Interesting!

So what other bits are you doing and why did you decide to change the crank and not go for a slip fit kit?

Hello Nick,

this is the second attempt with an other crankshaft, the first engine i build 2012 with a crankshaft from Australia, thats not good quality, the flywheel have not the right position, the sizes from rod bearing not corect, oil driling missing, and i have after 350km rod bearing damaged.

the steel was not good nitrided and soft.

for the summer i rebuild to 3,6l with H beam rods, ported cylinder, Gt2 inlet manifold, upgrade VTG Turbos, exhaust, intercooler Gt2 RS and other parts the result was ok but not enough for me 695 PS and 1100NM Torque (flywheel value)

here further pics from the first 3,9l engine (crank with 82,4mm stroke and new pistons 100mm)

Why you didnt go with OEM gt3RS 4.0 crank that most of us use..?

I would like go a other way, gt3 RS 4 l can anyone

But you`re right there would be less problems

PKM, I am in Stuttgart as well in Vaihingen. I have an 08 TT. I would LOVE to see your car and your build. I haven't been able to link up with any Pcar owners here ( I am an American and have very limited German language ability).


I would PM you but I don't think you have enough posts yet

Great looking build!

Very nice project.. Very nice work.. Congrats. I tried gt2 intake too but i saw more power on top rev and not at mid range...
I use now 996 gt3 intake with 83mm ypipe and gt3 tb. With this setup i have power also at mid.

Looking good!
