964TT

Hey Tim,

Thanks for the kind words, really appreciate that. I have been on Rennlist for years and got so much solid advice here, I feel like I owe it to the community to give back and share my findings and progression.
This year has been slow, as I had to do a complete rebuild of the engine and ran into some unforeseen issues. And luck will have it that the moment I can pick up the car after a year not driving in it I broke my left foot during sports...
But the car runs amazing. I could already tell by driving it from Hamburg to Amsterdam that the last updates to the engine are quite special. The main things that changed are the new pistons, the large valve & flowed heads, new cams, GT3 crank, GT3 oil pump and larger stroke&bore to 4.0L. It feels like the character of the engine changed quite a bit as with the very conservative tune it feels just the same as it did in the full tune with the engine I had before! Of course you are in unknown territory when you do a project like this. You change things and hope it works better.
As soon as I get to drive a bit more I'll post some findings. I'm definitely curious how the final tune will turn out on 98 fuel, I'm hoping some number around 750hp, that would be incredible.

So good to drive again!
The brakes are great, just cold feedback needs a bit more milage to improve. They told me between 200-500km when driven hard.
I haven't seen any other 964's with carbon brakes. Yeah Singer, but are those still 964's? I guess. Or not.

Here are some photos of the new brake system. Only thing I'm wondering is if I need to change the P/V, it is standard 964 C2. If anybody can share some ideas based on my configuration that would be great!

This is my brake system now:
-Front and rear 993TT caliper, front&rear 322mm rotors
-Pads are Pagid RSC1
-993 master cilinder (23,81mm)
-993 vacuum (9”)
-Original PV (45bar)
-Castrol SRF brake fluid
-Race ABS from BMW E30 M3 Cup

Gorgeous day around Amsterdam. Went for a drive, did some photos.

Beautiful shots. You definitely want a C4 m/c to help with those brakes.

I'm not sure why. I'm with a 993 m/c and vacuum now.

Car looks awesome! Just read the first 12 pages will read more when I get time. Great thread

Only missing bit from your brake spec is what carbon ceramic discs you are using and where from...Could you share that information please?

I did a bit of work with Freno the other year but nothing came of it. I nearly pulled the trigger on a 997 cup set-up a couple of times but wasnt sure if I was going 17" rims, but your solution sounds like the dream!

On the master cyclinder how about a modified 997GGT3RS - modified as per Snowmouse on here:

I'm intrigued regarding the rear brake setup...
993tt rear calipers require bigger discs that don't allow you to keep the park brake!
So what have you done here?

Whatever happened to the Volk wheels you were going to put on? I'd love to see a picture of them as I'm leaning towards buying them for mine. Thanks.

Hi Thomas,
what's the latest with the car?
I still think it's the coolest build out there & have been scanning the boards to hear how it's going since it's been run-in.
Have you managed to dyno it yet?
Are the gearbox & clutch holding-up ok?

Best regards,
Tim

Found this thread today. F*cked my my day totally.

Amazing story to follow. So much work!

Well done!

Lol just spent quite sometime reading this too I admire the OP with his unending love for the car. Finding the right shop, builder,and tuner is the secret. Not in my 964 but I went to almost the same experience under a scammer tuner on my 996 tt build fully built configuration (motor/trans and stand alone junk ECU almost 3 years!) never ran right and always breaking up above 4500 rpm. I changed shop and tuner and viola! 925 (1140 crank) to the wheels and can redline anytime without hiccups. Good luck with your car OP and Happy Motoring!

Haha, sorry!

To all readers, I will get back on this thread and continue reporting. It has been a difficult journey the last two years, to say the least. At the moment I am really confident that the people working on it now are solving all the issues and the car is coming back fresher than ever.
Over the years too many hands touched the car and crap has just piled on. I will share details about all this so others will work with more caution after reading about my problems. But what we are doing now comes down to bringing it mostly back to how Porsche engineered twin turbo engines. So the engine now will be very similar to a 993TT engine, with the oil routing and turbo position all the same. But of course I have better turbos, 4.0L and very different heads and exhaust.
In a week or two the engine goes on the bench and after adjusting VEMS and testing it will go back into the car.
Look forward to detailed report, photos and videos coming up.

Can't wait. I hope you can manage with the intercooler in the front. Would be a shame when you have to fit a big spoiler on the rear...
