Well after my engine failure March 10 2010 - its took me a lot of research and time to decide the way forward with my R35 GTR.

May 8th 2010 - I decided to go with this spec.

FOR MY CAR








ENGINE -

JUN 4.0 STROKER KIT (still unsure on the heads as of now).

Reasons behind decision -

JUN a cult name in big power japanese cars.

Got a great deal of Junichi Nakata (JUN main man)

Stroker designs lowers compression = improves the cooling of these engines.













A little info on the 4.0 Jun Stroker







TURBO KIT -


Greddy TD06-20G

reasons behind me choosing this kit.

i still believe the stock turbos and manifolds will create too much heat in the VR38 Engine.

this comes with maifolds, wastegates and other nice bits for a few K more than having my turbos re worked..

nope - but spe world of the 2 fastest R35 are doing it next..


basically then engine will work the same as a stock vr38 but because it will be strokered it will spool up faster and have more torque than a non 4.0 stroker..and also a good point it will improve the cooling of engine.

thistle and GTC will be doing the map

Are not sure I like the TD06 20G turbo. If you've ever taken the turbine wheel out this is a BIG / HEAVY turbine wheel. Looks like a boat anchor next to the Garrett GT30R turbine wheel. I'm sure this affects spool / response... Any one have thoughts on this?
