Okay here is the deal.....I have run out of time on this turbo project and it looks like I will not be able to get this head fully built. The Question of the day is:

How much boost will this take? GSR motor, godzilla sleeved block, je 9:1 pistons, crower rods, all new honda bearings, YS1 cable LS big spline trans with stage 5 clutch, and Quaife, Speed Pro, 900 cc injectors, aeromotive pump and braided hoses, ........BUT STOCK GSR head. I am running a STR style intake manifold....but I will NOt have time to get the head work done as planned

How much boost on a stock GSR head? Thats the Q.

Sorry for the grief.....just tired of riding my bicycle.

Noone can tell me what a stock GSR head can handle with good tuning?

 

all you would need on the headis some new valve springs and some good retaineers so you can rev it past 9000rpm. Overall the headwill get you around 450hp at around 25psi
