thanks a lot andy. great info. one more question. in terms of turbos, what is the difference in lag between a t3 and a t4? i know that they have the t3/t4 hybrid to have less lag like a t3 and more boost like a t4 but how much of a difference is it? aka at what rpm do they start to gain positive pressure and at what rpm are they fully spooled up? thanks again
I really can't say for sure, I haven't done much tinkering with turbo's. A straight T3 should be spooled by around 3000-3500 rpm, I'd assume the T3/T4 be a few hundred after that and the T4 coming in a few after that. It depends on turbo manifold design, compression of the engine and a few other factors. As far as I know, a T3 and T3/T4 hybrid are both very street friendly turbo and can usually be turned up to provide enough boost for just about any street car. Seeya.
