Trying to decide which route to take with my 91GT 5-speed. Do I go with the twisted wedge heads, TFS stage 1, new roller rockers/pushrods, upper/lower intake, & throttle body. Or just bolt on a 9lb Procharger and be done with it? The car is currently stock (Ex. pulleys and exhaust) With either option I will upgrade the fuel system, MAF, and install 3.73's. The cost for both options is about the same.
Which option will give me the most power for the $ (NO NOS)? Can the stock headgaskets handle 9psi?
