As a hi to many that posted on an older thread (ade pointed me to it), I had some time tonight and thought i would offer atleast something in return and post some pics. And I hate posting pics.
Nothing too stunning in the photo dept, just some hipstamatic filtered phone dumps but maybe it will break up the monotony.
Its truly a shame that some of us dont live closer enabling the sharing of a local pub.

Some of you know ive been slowly building a little cheater hot rod. No rules restrictions for this one and its going on the road too. I want to get back to just firing something up and getting out there when I feel like it. I sense thats where everyone shifting back into aircooleds from 997s instead of going forward is coming from too, but thats just a guess. It might just be smelling of petrol though, if so i am covered just fine here too.
Its all from the porsche parts lists (just maybe not parts lists that most get to see) so its really in the spirit of what Porsche used to be about when they would embrace and encourage this behaviour. If you get what that was, or are just prone to nostalgia this car will probably tickle you. I know most wont get any of that but thats ok too. Its a watershed moment once again, just try to remember when you look back, a few of those being left behind might just be swimming in the other direction. We dont all need your pity.

Engine went into the car a couple of months ago but I have literally had zero time to follow it up with more work.
if you like looking at engines, hopefully this will give you an enjoyable few seconds away from the usual posts. If you are used to looking at these things you might get several seconds extra fun.

If you want me to tell you whats roughly going on with it let me know and I will share a little bit of info.








The box is a regular 2005 spec 6Cup piece. Freshly rebuilt but totally stock. Insides are a bit different from the street box, the diff is a monster and gear ratios are very different. Some of you might notice the oil supply is filtered and theres no plastic crap on the heat exchanger. Its solid mounted too. If you think those Cup cables give you in cabin noises, give this a whirl.


Ive also thrown in a couple of cabin snaps since i had them. Might give folks a smile if nothing else.

Dear Boy! Looks similar to the view I remember from a 996 cup but with Motec (?) dash and no doubt a great big hairy arsed engine! This chap looks like a lot of fun as does the setup conundrum! Does one take a little camber off the rear to help deploy the humongous torque that ( knowing you ) the engine has and risk oversteer city or do you go optimum and draw from the skill cabinet??

Thank you for posting Old Thing. You are in danger of making this forum interesting again. But prey tell, how will you possibly be able to drive such a vehicle whilst using your arms, legs, arse and your brain all at the same time??

Surely it is impossible???

Great to hear from you again, looks like you have been quite busy too!

Your hot rod build is looking good, wish I had the time/skills/patience/money/intelligence to build one biggrin

Maybe there should be another separate sub-forum in the Porsche section for major modifications like in the TVR section.

Now this is what PH is for smile

BUT how many owners has it had? Did you get the DME checked before buying the engine? Have you had a low temp thermostat fitted? Your warranty will be void. And what about depreciation?

Merry Christmas

Its 3.6, I like that engine for the 996 (and that engine in general) though its not a run of the mill 3.6 Cup engine thats for sure. Even the engine case is a bit special.

The car isnt built to run for any events. This is just my, screw it, I will build what I wish porsche would project and chance to build what I always felt would be a fantastic car. There was a time not so long ago when they would have given you a whole bunch of support to do this sort of thing. The will evaporated a while back (before I ever had a porsche) but the way was still there even with the 997. Now theres neither.
There was always so many ideas or improvements that were just crying to be brought onboard in almost every area of the car but regs limitations on the race cars mean you cant ever do anything. Free from those shackles meant I could just build the best (in my mind) damn car.
Im going to drive it on the road when i fancy a blast, take my kid out in it, hopefully do some trackdays with friends etc. The friends part being more important than the track part. Without people its just going round in circles. I sense a nice trip up the west coast as part of a convoy coming in my future too.
The only slightly odd thing just now is that its existed as a concept/idea/work in progress for so long that I am struggling to change its function back into an actual car now its moving under its own power again. Im sure the arrival of spring will help.
Ive not settled on a final decision for the interior side yet though. It has a 1967 911R vibe going on just now that I will suck and see once I get using it properly. Its a bit more homely than a regular Cup but not a lot more. I may find I need to dial in back a touch yet in that regard. Technical decisions are always easy, aesthetic ones much less so and interior is very much the latter. Its probably hovering right around 1100kg total weight at the moment though so thats adding to the leave it as it is feeling.

hahaha, The secret to reaching equilibrium on the first paragraph is to be very much slower than you are Mr Rance. Then your compromises are all sorted by the natural order of things.

Thats actually a topical point raising though regarding setup, I have work to do there for sure.
Its currently over 4 deg neg camber front and back and looking at that and some PS2s one can see immediate problems right? Add on a total rubber free ride (the entire car, subframe, engine, gearbox, joints etc etc are solid mounted) and theres a need to get it corrected in short order.

Excitement overpowered common sense and I drove it round the estate (industrial, not country sadly) when it first ran. No setup at all and each wheel toeing in a different direction. Never again. Test runs are cancelled until at least a starting point is set so thats first point of order when I next pick up tools. Second is to remove the lock stops on the RSR steering rack. I left them on confidently after conducting some very scientific road situation avoidance tests (I drove round some trucks in a paddock) and passing with flying colours. Apparently they were less to scale than I first thought. I had to do a multi point turn just to get round some less than obscene corners. Horror inducing when you are wearing L plates, abject mortification when you are in a bewinged brute running a 110db exhaust with a 1500 rpm idle and belching smoke as the assembly lube burns off the engine. Subtle it was not.

LOL at the last part. No kidding huh. Did you notice the lack of vacuum line on the intake plenum? No booster and no ABS for me. And a real cable on the throttle pedal. My dash has GPS installed though along with a bunch of data logging so its not quite the stoneage express.

Dont worry, I have all that covered. I know the rules!!!!!
Max RPM stored in the ecu- 9370. Thats type 1 right? warrantable?
Low temp thermostat- bizarrely yes (go figure).
hmmm, things get less clear after that. I shall get my coat.

Merry Christmas to you too.

Great stuff! clap

Makes a refreshing change to read about a properly technical and truly exiting project from somebody so hands on.


Keep us all posted, and all the best for Xmas and new year.

Great thread fioran0, I hope to convert my GT3 into sort of a road-going cup car spec one day, so will keep an eye on this thread with interest smile

Just saw the car on your profile. Very nice. You're not far off a Cup.

Very nice.

So, tell us a bit more about the chassis setup :-)

And how does the sequential box cope with road use? Do the downshifts get messed up if you change gear at less than 6krpm?

Lol, thanks, it's about the experience for me, so would like to strip the interior and have it painted white along with neat wiring loom, full cage, etc. it's already madly fast, so making the experience "feel" faster with more engine/ road noise and an internal race car look is on the cards next smile
