how much more bhp you gonna get?
not sure realy,i would imagine it being over the 300 bhp mark.the current set up is only limited by the following things,the exhaust manifold,which if i changed it now would pull the plug and prob add another 20 bhp on its own, then there is the fact that if the top and bottom of the engine is strengthened,forged pistons and all the other bits,cams head work, that will allow the boost to be increased and also the rev limit.
courtenays recon they could add another 4 psi boost,which is just a pully size change,and is actualy quite alot ive been told, so i guess you could look at 300 bhp maybe.
