You could just buy another mr2 with the gze already in it .....
Bugman..Guaranteed to give you 200hp? thats pretty much the limit of the gze, and they guanrantee it
But big Mike definately go the turbo, (im still lookin for a manifold )buy the gze motor and get the turbo on it b4 u put it in the car there is way more power potential from the turbo than the sc(like i said b4 200hp is pretty much the limit, turbo is wayyyyyy higher), and with todays bb turbos you can almost get as much torque anyway. HAVE FUN!
