I can always build a good engine and turn the boost down that is no problem, I have sold all my standard engine parts the only thing I have at the moment is the block, which is ready to be sleeved. I'm in the market for a P12 head which i will purchase from Nissan Japan at some stage. 250rwkw will not be enough for me, after driving my 800HP + R32 GTR, but as with any new car i will start off with small power and slowly wind the power up until I reach the sweet spot. The wider the tyres i run the more power I can lay down. I may even purchase a set of 12.5" rims as my 11.5" were for my +50mm Guards, I am now running +70mm guards. More measurements need to be taken.
