hey i need some help i got the gm stg2 i was thinking of getting the gm stg3 pulley its 76mm and the 2 pass intercooler should i just go for like a 2.8 or 2.6 and 60lb injectos that wont harm my engine? and at the gmperformance web site i read the stg3 FAQ and it said that if i go smaller that a 76mm pulley i need a icebox intercooler and exhaust ported head to control temperature is this true if ya got some good ideas or the best way to do this it would be freaking badass if ya helped me

 

It all depends on what your going to do with the car, is this your daily driver, do you still make payments on it, do you want a warranty, alot of factors play a role. Imo i would go with a 2.8 personally if your going that route, but other then that why arent you happy with your stage 2, the lower you go in pulley size, the more problems and other mods your going to have to buy to go along with it.
