Nismo just released their S-Tune Spec 2 engine Kit (S2) to all japanese z owners (sadly if we want to do that, we gotta ship the whole engine back, then they will build it there to receive Nismo ECU, Air Intake system and the Carbon Fibre engine cover). It surprised me that they only changed conrod bolts at the bottom end though... didn't use any forged piston or rods...

They are using nismo cylinder heads and I guess the power figures quoted are very conservative... running around 11.5:1 to 12.0:1 compression ratio and only achieve 325HP on the 06 and the anniversary engine and 320HP on the 03 and 04 engines...

But anyway... good too see that they have got it out finally!

Looks cool, too bad we always get the shaft when it comes to acquiring japanese parts for our cars.

 

is that flywheel or whp?

 

^ If it ain't at the wheels it ain't anywhere for what that's gotta cost.

 

Very Strange
The VTC sprockets are now missing in this upgrade, hence the lower HP than the original S-Tune Spec 2 on the 287 motor
