Hi Guys,

I've been meaning to start a thread for a while, more to keep a log of the build/ keep up with the history than anything, so here goes...

I've hankered after one for a long time and had promised myself once i was in my own house i would treat myself. As you can imagine the house choice almost certainly revolved around the garage space available. We hit it lucky and almost as soon as we were in i started looking, perhaps not the best time to nigh on skint myself but with the prices on the up it seemed like it was now or never!

The brief was quite open, any colour, round or square, standard or modified but the body/shell had to be very good, I'm fine mechanically (relatively speaking!) but bodywork scares me. I wasnt even bothered about body style initially and nearly went for a touring project but then in my head my perfect 2002 vision wasnt a touring.

I had nearly sorted a deal for a very nice standard sahara beige 2002 that was on the 02 forum but through the sellers holidays etc the sale dragged on and whilst i was on a 4 hour round trip parts run for said car i received a PM on there offering me the car that i ended up buying.

It had a restored body and a nice list of parts, during the resto it had had a colour change and turbo arches/ airdam, this car was already 'ruined' to the purists and i had always intended to modify the car and do euro drives/ track it. The Sahara beige example was original and perhaps too nice to 'ruin' and i ashamedly (in a way) decided to back out of the sale.

The car i bought was located with James at JFI Classic Cars in South Wales, an 02 specialist. Long story short i ended up buying it minus an engine or gearbox fitted (a tii bottom end and e12 head included as well as a super rare 235/5 gearbox). The car was 5 hours away so the better half and I set off at 3.15am one Saturday morning in respect that James was to open up especially for me to view the car, the journey was great and we arrived an hour early:



The car was as expected and it was great to meet James, a deal was struck with the owner in the back ground and i returned with a friend a month later to bring it 5 hours up north, this journey wasnt so great as the transporter broke down 80 miles into the drive and we had to stop overnight in Barnsley and bodge the drive belt in the morning to complete the other 450 miles or so! Pic's at JFI and just before departure home:













Tucked up back in its new home around 6 hours later:



When we picked it up the bottom end was sat in on its mounts, the head was in the boot along with the gearbox as well as a host of random parts/ nuts and bolts. First job for me was to get the bottom end out and onto an engine stand, whilst it was a rebuilt bottom end and hadn’t covered many miles it looked to have been sat a little while and I’ve always wanted to build my own engine. As the head was already off I decided to strip the rest down and rebuild it.

I’m lucky in this sense as I’ve helped out at a competition engine builders for the last 14 years or so, my boss that runs it is oldskool and a wealth of knowledge on a whole host of marques, especially bmw. It’s a small ‘man in shed’ type machine shop but a lot of well-known companies get engines built by him and his son, his cylinder heads/ engines perform unbelievably well in a lot of cases. Engine stripped and packaged off for me to take in:











Crank was checked and polished, clear to see that it’s had some trauma in a past life with the amount of grinding it’s had previously. This was a cause for concern at one point as I was going to run 144mm rods and some custom pistons with a higher compression ratio however something else has taken up that allocation of that money so I’m sticking with the bottom end as it is for now (more on that later). The pistons in the block measured up well and in great condition so a simple hone was all that was in order:







Whilst the bottom end is staying standard i’m still going to have the head modified, to accompany this we’ve spec’d a camshaft for it and to match this I’ve selected the mildly uprated Schrick single springs and KM Cams steel rockers. Standard valves will remain for this iteration of the engine. Along with this I’ve got all new rocker shafts and hardware, some random pictures:







The car also needed a clutch, I thought I’d future proof and go for the Helix Autosport one along with a steel billet lightweight flywheel. In total, including the clutch, there’s 3kg’s saved here. Not too much for what will primarily be a road car but enough that it should make a nice difference to performance in the lower down gears. I’m still waiting for the shorter 22mm arp flywheel bolts to come in so we can balance the bottom assembly.

Once I had the car up on axle stands I could have a better look underneath, all new to me as I’ve never looked under a 2002 before! The shell is like new, the sub-frames powder coated and complemented with new bushes (some look like black powerflex items) and new kunifer/ braided lines ran throughout. However the rear driveshaft boots had split and chucked moly grease everywhere and the diff looked like it had been sat at the bottom of a river, along with the state of the driveshafts:











This led me to refurbish the driveshafts and after checking that the diff plates weren’t worn I had the cover off and refurbished that and gave the case a lick of paint:











The driveshaft bolts were loose/random/ rounded off so I ordered all new hardware to mount them again, new crush seals and LSD oil. The spacers for the e21 diff that had been used appeared to be old stub axles with the stub’s cut off, this in my eyes is a bodge and they are also rather weighty. Tom on here was luckily selling some Jaymic aluminium ones:



Pictures all back together:







Whilst on the subject of the transmission, the gearbox was reported to have a slight crunch from 3rd down into 2nd when driving spiritedly. Being that the car will be driven spiritedly a lot we thought we’d get the box apart to inspect it. I was nervous about this, any reports available on the internet makes it seem like it’s nigh on impossible, luckily my good friend helping me with this build is more confident and competent at this sort of thing. Results were not good, corrosion on gears 1-5, 1-4 needing replacement, 5 is useable. 4 out of 5 baulk syncro rings also needed replacement. As you can imagine these 235/5 gearboxes are quite rare and parts are expensive for them if you can even find them. The following pictures are where the piston/ rod fund has gone, im still awaiting the baulk rings before it can go back together:















We and the specialist who supplied the spares are under the impression this box was built with knackered gears to sell on, I feel sorry for the owner previous to me who probably paid an arm and a leg for this box. All bearings appeared new and the casing restored and other than the knackered gears/ syncro’s, it is a gem. My dream ’02 has always had a dogleg box in it so I can forgive this expensive development in the project.

I plan on running the car on Jenvey itb’s and a DTA ecu, for this I need a high pressure fuel supply. The car ran EFI injection in its previous guise but when I got the car it had an old carb fuel tank with it, somethings a miss but nevermind, ill work with what I’ve got. The tank is out and currently being vapour blasted, having a fuel return boss welded in then getting painted. With the carb tank having no baffle round the pick-up I decided to run a swirl pot set-up instead. Webcon do a swirl pot with integrated high pressure pump which should do around 200hp with ease, I bought one and mocked everything up along with a facet to act as a lift pump. With this being above the tank I expect it’s life to be reduced but we’ll see how it gets on. It’s all installed properly now and awaiting the tank:











I also got the steering wheel that I’ve always envisaged for the car. My friend that is helping me runs a garage that mainly specialises in porsches. One of his customer’s cars hillclimb cars has the exact seats and steering wheel I’ve always lusted after:



After seeing these in the flesh I think this is the type of interior ill be aiming for. Steering wheel first up though. I always sourced an old Momo horn push for it, momo center holes must have been slightly bigger at some point as I had to ‘modifiy’ my brand new prototipo for it to fit, a little daunting!









To bring me about up to date, I bought some camber/ roll centre plates. These needed modification to clear the ball joint fixing and a bolt needed cutting down but they were on after not too much chew. I was missing a lockwire bolt so have ordered one up and then I can lockwire them as bmw intended. There also wasn’t any spring perch pads so I bought some new ones and stuck them in place. I’ll also wire the springs to the top suspension cup before I reinstall. I’d like coilovers up front to get the car sat right but haven’t the money for them at the moment.









Also had the seats out, I’ve never taken much notice of them really but im growing quite fond of them. I need to research seat options later down the line, I’d like the Cobra rsr copies of the recaro items in the Porsche above but need to see if they can be mounted on original ’02 mounts and not be too high. The e21 Recaros have been cleaned and leather treatment applied, I think ill have the bases off and refurbished with new stickers which seem to be available. If i get offered a good price i think i may sell these at some point though.





Thanks,

Scott

Wow, overwhelmed with the responses, thanks to everyone that has commented. Im glad it comes across that im trying to do things properly and to a high standard!

I've now got all the gearbox parts and the oil so that can go back together soon, further to that i just need a new coupling and bolts and the box can go back in.

Front struts are wired and built back up and reinstalled, brakes all sorted and installed too.










The tank has been blasted/ welded and had its fuel return welded in and is being painted soon, just need to buy a rivnut tool to secure it properly, i wasnt overly chuffed with how it was fixed in when i got the car.



The block is finished (Decked, bored and honed. Needs a paint of course!) and the 22mm s14 ARP bolts i needed for my flywheel have shown up so the bottom end can be balanced now. After that im just waiting on the head modifications to be done and can build it all up whilst i save for the jenveys/ DTA ecu. Sadly it'll be money that slows the project down as much as anything else for the next 6 months or so! Hoping to have it on the road in its first iteration for Spring/ Summer next year!







Cheers for now!

Great work and an enjoyable read, thanks for posting.

These have such a lovely shape and such elegant lines. Pretty sure if I'd not been brainwashed into Saabs at an early age, I'd have one of these in my classic garage now, along with a Lancia Fulvia (equally lovely lines).
Thanks, appreciate you reading it!

We must have similar tastes, I had looked at fulvias and even though the handling is good I wanted a rwd car to do and have always been taken by the 2002. Stunning things though, we have done a few of the strange and quirky engines in them where I lend a hand on Saturdays.

Lovely looking BMW, but I couldn't let this last pic go... if you are going to do this Bavarian build properly you need to sort that glass out!
Haha noted! Sadly (or not) this car has come before many household items that would be much better in day to day life than a none working 2002. I should move an Erdinger glass further up the list though!

Always loved the 2002 and this one is shaping up to be a bit special.



Are those two/four-piston brake calipers standard, or has it received uprated brakes at some point in it's life?
Thanks, I'm hoping it'll end out being pretty special when it's done too.

Well spotted, the calipers are m535i 4 pot items, hubs are 6 cylinder e21 and discs are vented e21 320i items. The rear has also been upgraded from drums to mk1 golf solid front discs with what look to be Mk4 golf rear calipers, including the hand brake mechanism. Sadly this means I can't run 13 inch wheels.

The front calipers have 4 bleed nipples and dual feeds as the 2002's came with twin remote servos. I'm going to keep them for now and see how I get on!

If the car wasn't a tii then Volvo 4 pot calipers and different hubs can be used (much the same but different spacing) but the tii and turbo came with much thicker stub axles.

This looks like an awesome build! I await to see what happens.
Thanks! Update below!

Feels like I’ve spent quite a lot of time on this but don’t feel all that much further forward! I guess I’m almost back to where I started when I got the car except everything mechanical is now done properly and there’s also lots more shiny bits!

The main focus recently has been building the bottom end back up whilst I wait for the head to be modified. The gearbox is still in bits, thinking being I can use the input shaft to set the clutch on the flywheel so the gearbox will probably be one of the next installments!

I got the block back from where I help out at on weekends sometimes (read Saturday job of 14 years!), great job as I knew. Even though its spent hours in the chemical hot wash I can’t stress the need and importance of an immaculately clean block. I spent hours further cleaning all the oil galleries and mating/ bearing surfaces. New compression seals, o-rings, gaskets etc throughout. Following this I painted it in satin black and started the bottom end build.





Before and after as an example on big end:





Piston:





I set about balancing all the static items since all rotating items had been done. This took me around 6 hours, one piston was 8g heavier than the rest and that’s a fair chunk to take out of a piston, it wasn’t balanced very well as it was. In the end I got the rods perfect and the piston assemblies to within 0.4g, rather stringent for a basic build but when your own time isn’t costing money it was worth it! My board of scribbles:



Job done:



Next was for ring gapping and building each assembly up, all spot on out of the packet so no need to change. I did check every single one though and took the corners off, something many people forget to do:







Crank in and torqued, turns nicely so that was a relief!



New Keyway:



Pistons in:





E21 oil pump rebuilt and shimmed with 2002 pick up pipe, new pulley and locking tab installed:





Chain and guides on:



Front cover, water pump, crank pulley etc all fitted as well as that lovely flywheel:







Then time for the baffled sump that my dad kindly painted for me, also has oil temp boss in it with m22 to 1/8 NPT reducer:





In line with the car patiently waiting:



Next update will hopefully be with the boot finished up and fuel tank in properly then onto the gearbox build!

Thanks for reading,

Scott

Looking good Scott!

You'll be done before me at this rate!
Cheers Ed, and i doubt it but never know the way things are going!

Looks great Scott. (Great Scott!!? Sorry. rolleyes )

Car is looking great.

Hopefully once done you'll come on one of the 02 runs or maybe Llandau for a track day? The 02 crowd are a good bunch as you may well have found out already? James @ JFi is a friend and genuinely nice guy.

I'm sure your e21 seats will sell quickly should you decide to part with them. In fact, I probably know someone for them. Anyway, look forward to updates.

Mark smile
Thanks Mark, both of those things are on the agenda! Agreed, the community feel with these cars is great, completely cemented my decision to skint myself and do what im doing haha

James mediated the sale of this car for me/ the seller so will always be grateful for that, you can tell James does it for the cars and not the money too which is nice.

Thanks, I don't like selling things because of how most people are but if someone you know really is in need of a set and makes it an easy sale with a fair price for the both of us then i'd let them go. They are great seats but don't really fit the long term plan for the car so feel free to send them my way!

What great attention to detail, and the 2002 is the best looking BMW to my eyes (along with the E21) - delicate but purposeful.

You're not a million miles from me, I'll keep my eyes open once you're on the road.
Thanks, im along the same lines, its certainly my favorite bmw! I see you're in Richmond, not far at all, im just up the A1 towards Durham. The competition engine builders i help out at is in Northallerton too!

I had a 2002Ti back in the day with twin 40s IIRC, Martini stripes, and BBS wheels, natch. It always struggled to stay in tune for some reason and the gearbox had the same 3rd to 2nd graunch that yours had. Come to think of it, my later E21 320i had the same issue too.

I'd love another 2002 and if I did, I'd want one just like yours. The workmanship looks fab. I don't think I've driven any car with better visibility.
Sounds interesting, dont suppose you've any old pictures? Bet it sounded great on the twin 40's? I love the idea of carbs but just dont trust them thus the idea of jenvey throttle bodies!

Did your 2002 have the optional dogleg 5 speed? They have the old style porsche baulk rings which by all accounts are a little 'fussy'. Mines yet to be rebuilt but have all new baulk rings and gears 2-5, an expensive do but this gearbox is an important feature for me.

Appreciate the kind words, i've never driven one so ill have to take your word for it!

mumbojumbo1 said:
Could i ask what you used to achieve the black engine block finish?
Sure, im ashamed to say i was lazy and used this stuff from halfords! I was dubious but the stuff is great, goes on really well and dries smooth. Satin is my favorite finish but there's matt and gloss too and red if that's your sort of thing.

I'm just thinking about my next track project so will bear you in mind (although I have a house extension to pay for first).
I'm a desk waller in my full time job and purely go there because i enjoy it so safe to say i make no money from recommending them and purely do so because they are genuinely awesome with engines. Im new to the house owning but can see it will take up all of my funds in the future too!

My advice: Finish the 2002 before you do anything to the house.
I used to have several car projects on the go, then I bought a house (late, I was 33 when I bought my first one - see aforementioned car projects) and the last project was never finished. Now, 14 years later I'm really only just getting back to where I can do 'car stuff' as often as I'd like to.
Finishing this is quite high up on priorities, rightly or wrongly! (Before marriage, kids etc! Luckily i've taken the plunge young enough that this is feasible and makes sense in man maths terms and i have an understanding missus!)

This is going to be awesome when done. Nearly pulled the trigger on one of these but the wife didn't like the look so no go. Guess I'll have to enjoy reading about yours getting built up instead.
Thanks! They are supposed to be ridiculously fun to drive so i really cant wait, i sure hope it will be awesome!

A little more progress. I mentioned previously my dad had painted my sump for me, I also had my fuel tank soda blasted so he kindly painted that for me too. I had a boss welded in for the fuel return as my car came with a carb tank instead of the Tii one. With the fuel fitting in the boss it sits a little proud but it’s not too much a cause for concern.

I also snapped the pipe on the old fuel pick-up/ sender unit so I bought a repaired one and the fella who I bought the car from kindly sent me a spare that he had, much appreciated. I fitted that with a new o-ring and installed some heat reflective tape I had for where the rear silencer gets rather close to the tank.







I bought some sticky back foam tank lining from wallothnesch and installed that. Because the tank is a carb one, the securing holes are different for 3 out of the 5 holes so I had to rivnut these but now the tank is properly secured. Also bought a new rubber filler neck/ gaske arrangement and a lockable petrol cap. Tank in:












I need to get some smaller bolts but the longer ones did a great job of installing the tank with the foam at its original height, without risk of me stripping threads etc. Now the foam is compressed ill just swap the bolts over with shorter ones, 1 by 1.

To finish the install at the rear I need those shorter bolts and a 6mm to 8mm fuel hose connector and a small length of 6mm hose and I can get all the hose clips on and tightened up. The hard line to the front is already in, as is the return. I’m also going to carpet the small section of the boot at the rear that is body colour, underneath the swirl pot arrangement but I need my new battery/ battery bracket to show up before I can do that.
I also popped into my friends garage (A Local German specialist that builds/ looks after/ repairs some high quality cars, mainly 911’s) to borrow a slim 30mm socket so I could torque up the crank pulley nut, the new pulley with integrated trigger wheel wouldn’t allow the socket I have inside! My friend also helped with the initial stripping of my gearbox so whilst in there I grabbed my input shaft so I could fit my clutch. Pics below:







That’s about it for now, hopefully we’ll get the gearbox back together at some point soon and my cylinder head might get started…

My battery, cage and m6 female to post mount adapters arrived yesterday and it was a rare night where I was able to spend it in the garage! Box of contents that showed up at work:



Thought I’d weight the new and old and was pleasantly surprised, I knew the old one was a big old beast but not this heavy! So overall a nice 12kg saving.





Bit of a mock up:



Some drilling, Riv-nutting later (lots of sweating, drilling into the thing makes me stupidly anxious!) and amateur carpeting later:





I’d bought a big roll of automotive felt backed carpet off ebay along with two cans of carpet glue. It was my first experience of carpet glue so I’ll treat it with a little more respect next time, that stuff is STICKY! Sometime next year when ill hopefully have a cage in ill use the rest to carpet out the rear.

I also bought a 3/4 pressed plate off ebay and got that on. I’ve got the full size one for MOT’s but with that fitted it blocks off the vent in the airdam and I think this is where I’ll fit my oil cooler when I get around to ordering one.







Thanks for reading,

Scott

I am biased because I own a Dolomite Sprint but having driven both cars I think that the Sprint and the 2002 tii are about neck and neck, that the Dolly edges it on steering, whilst the BMW edges it on overall urge and looks.

The points the dude makes about BL potential are well made.

Edited by Breadvan72 on Monday 9th October 12:36
My comment was tongue in cheek but especially the way 2002 prices have gone, the dolly will be the better buy no doubt. Big fan of the sprints, especially the look from the front end!

Steering on the 02's seems a bit marmite, i've stuck with the steering box set-up (im actually refreshing it all now funnily enough!) until i can make my own mind up but may convert to rack and pinion further down the line.

Yeh its a shame about BL, the article sort of brought it to light for me how close it was, what could have been!
