does anybody know if you can get 245/35r17's on the front of an M3 on 8" rims? ET15.

Unlikely IMO. They will likely rub on the arch liner when on lock.

Use Wayne, hes awesome. That's where i'll be taking mine when its done and thats who my friend running the 911 specialists solely uses.

Yes, he does have a very good reputation and I know he's done a good number of s14's before. He's also developed a coil on plug conversion for people running the OE ECU etc. I just wish he was a bit nearer! It'll mean trailer hire and hotel but sure it'll be worth the effort.

I was thinking the same thing. In the past I ran 215/40 but I wouldn't mind going a little wider if it were possible without swapping to Evo front wings?

Another shout for Mr Scofield here! (he did a very thorough job on my old 106 Rallye hill climb car) Or even Dale Bladen of Bailey Performance (using him for a full MS3 install on my 951 race car in the new year, he also has a great reputation).

Well done for persevering with this and I'm very surprised with the issues you've had with the previous mapper, as he had god-like status with the peugeot racers!! Completely unacceptable attitude shown to you, what a complete disgrace!!

Hope you have much better luck this time around

Some people have issues with 235/40 17. The Evo front wings don't help with the issues folk normally have, that is rubbing on the liner and rubbing on the inner wing seam above the wheel arch. Along with the Evo wings (which have a 10mm larger cutout diameter, but are no wider), the Gp A cars had extensively modified inner wings so they could run low enough with larger wheels.

I've made contact with Wayne and hopefully have the use of a transporter for when the time arrives, which will make life and the 6 hours plus (350 miles) a bit easier. As it stands though, I'm unsure of the final build cost and it could mean I simply cannot afford the additional cost of fuel, hotel etc. I'm working / saving as hard as I can but it may be that I have to sell my split rims and redeploy the cash.

Funnily enough, I re read the exchange of email / messages I had with the previous chap to see if I had said anything that might have instigated his response and at one point he actually accused me of tampering with TPS settings and causing the episode of rich running I'd suffered back in August. I hadn't touched a thing. He also accused me of wanting to pass his map on to at least 2 of his competitors. Quite how he deduced that I have no idea? Again, it wasn't true anyway. He certainly holds himself in very high regard though!

I saw that on an M3 shell ARM are modifying for its owner, so that it can run some 18 or 19'' super touring wheels. (Against their advice I might add and it was such a mint shell too) Unfortunately the owner appears to be motivated by ''stance''.

What tyre sizes would you suggest Steve? (on 8 x 17 ET15 all round)

[s62]

I have been running 235/40/17 on 8" Ultraleggaras w/o problems.

Would like to be able to run wider in the back, what is the consensus for max rear tire width?

[anonymous-user]

Ok, i'm a bit late to this thread, but i think it's pretty unlikely a rod spun due to any over heating! To get sufficient loss of clamp on an otherwise perfect rod bearing due to rod temp would be difficult without leaving obvious witness signs on the rod. What did the crank and shell surfaces look like after the failure, any pics?

[SebringMan]

I have just read this thread from where I last was. Unfortunately a few of us have been there and got the T-Shirt. Good help can be very hard to find!

It is a real shame that things have panned out this way but hopefully you'll be on the road to victory soon.

I guess I am moaning a little much about my E46 but it's all about perspective at times .

I echo what Rich said. The mapper in question is practically worshipped in Peugeot circles! It's not the first time I've seen a brand specific person in the scene be iffy however.

Likewise here is to you having some better luck now .

The overheating was just one of a list of things that accumulated over time to be honest.


Thanks chaps. Hopefully there's some better luck on the horizon for 2018?!

Happy Christmas!

A random question but when did you change your username! I always knew you as E21Mark from all of the other forums, including RR .

The new name is more fitting to the car I admit .

A couple of months back I think, although only on here. Mind you, this and RR are about the only forum I use nowadays. I still use s14.net but mainly via FaceBook.

Am looking forward to attending both RR events in 2018. They're about the best shows out there in my opinion and I love the diversity of cars. I've met some really good people through both forum though.

My ITB's and valves are on route and should be here on Wednesday. Christmas and New Year always end up being a bloody delay I could well do without.

I still haven't bought any tyres either.

[e30m3Mark]

JC Racing did a great job on the ITB's and also supplied a couple of inlet valves I needed.

Ordered 4 of the little plastic caps for the adjusters. If indeed they are adjusters? Those a new boot roundel were over £90!

I think I've decided to go with Nankang AR-1 tyres. They're their version of r888's and the reviews I've seen are all pretty good. I'm just waiting to see what they can do for me on price before I commit though.

The only other part I need to get is the new oil cooler from Mocal. I just need to be sure I get the right size. I'm also tempted to get an Accusump. Anyone who visits here ever used one?

Glad they came through on the itb’s Mark, they look great!

I think I’m going to go for the r888r’s on the 02, or the Dunlop dz03g if I’m feeling especially flush!

I must admit, I am pretty impressed at just how much improved they are now. One of the butterfly was slightly twisted before and they are all spot on now. They also matched the mounting block ports. Obviously being nice, clean and shiny is an added bonus.

The engine should hopefully be back for the weekend and this time I intend doing a few smaller jobs that were missed last time, such as painting the block and milling the M Power script on the cam cover. Other than those few cosmetic jobs and buying a larger oil cooler from Mocal, we should pretty much be there. Inside, apart from the Stack dash display, I would like to get my seat mounted lower in the car. The problem is there's not a huge amount of space and I have to run a larger seat, as I'm built for comfort not speed. I'm hoping I can also bring the seat forward an inch or so, then recline it a little more, so that my helmet doesn't hit the cage. All that leaves then is to fabricate a cage door bar, that is low enough to run parallel to the sill, so I can get my weaker leg in and out more easily.

I've never run the r888r's but the older r888 were very good. I also tried the Silverstone FTZ and they were very good indeed. They were quite a bit cheaper too. I think I am pretty much sold on the Nankang AR-1, although I believe there is only the one compound available. They're one of those brands that I seem to recall were pretty poor a few years back and were considered to be about as good as Ling Longs etc. Mind you, when I was a kid the worst tyres for our bikes were Yokohama, or so said the word on the street anyway!

Accusumps are fitted to Lotus
I had one on my 2-11
Easy to see the pressure is maintained but from memory they are a pain to setup and maintain - in so far as there is a procedure

Gaskets leak were common on mine

[Richair]

I have AR1's on my 951 and have been impressed with them. Testing with them has been limited to just a day at Curborough and one Oulton so far, but I struggled to cook them at Oulton doing some very long stints (circa 8-10* air temps). They were also good during damp conditions. Comparable to the R888R and DZ03G's it seems, I rate them.

GrpA cars used baffled wet sumps and oil filed to the first kink on the dipsick. This was sufficient to prevent oil surge issues in long high (higher than you are likely to see) corners.

Do you have a horizontal baffle in your sump?

WRT Oil cooler, as I have said before, you should be fine with stock. Improve air flow to the stock cooler would be my first port of call if I had oil temps above 115 on track. It is just another unproven change which injects risk. If it aint broke and all that.

[e30m3Mark]

Hopefully the tyres will be here by early next week. 235/40 are out of stock, hence delay. Good to hear more positive comments about them though.

Yes, the VAC sump is baffled and I'll be sure to make sure the oil level is as you said. The Accusump was just a thought really but have read too many problems to really consider fitting one. Am going to alter the cooler mounting, although my OE cooler is looking somewhat tired / battered, hence swapping to a similarly sized Mocal. I know what you mean about risk Steve but ARM have run the same one for a few rally stages now and seems up to the job.

[stevesingo]

I believe this is your sump.



You can see the size of the opening through which the oil pump passes and the use of what appears to be sprung trap doors.

Now compare to a replica BMW MS sump



The aperture for the pump is much smaller and the cutout for the big end to pass through is a minimum. This stops the oil surging up the timing chain cover under heavy braking. It also uses rubber flap valves for the lateral baffles.

Keep an eye on your pressure when under braking!

[e30m3Mark]

I see what you mean. I'm going over to the workshop later so will see if I can take a look for myself. Thanks for taking the time to post Steve. I'm no mechanic but am still keen to get an understanding of what's required.
