senior project

[blackeclipse]

I have to do a senior project to graduate high school so i decide to do a new turbo and exhaust. My questions are: what are the differences between b16g and evoIII 16g such as spool up time, and power on a pretty much stock system, how high can the boost be on either with stock fuel pump and injectors, and should i get just get a 3" cat back or get the 3" downpipe too.

evo III is a little bit better turbo.. little bit faster spool and moves a little more air than a normal big 16g. max psi on a stock fuel system? about 15. if you are going to do a 3" exhaust do the whole thing. 3" downpipe, 3" test pipe, 3" cat back oh and dont forget to port the 02 housing to match the 3" downpipe or get an aftermarket 02 eliminator exhaust for even better flow.

one other thing i forgot to say was when you put that exhaust system on expect it to creep. Order the turbo with the bigger flapper mod and if it still creeps you need to consider getting an external wastegate.

At about what rpm does each turbo hit full boost/ start building boost.

well i have a evo and the one on mine is considered the Big 16g and spool starts at about 2800 id say after 3000 its pushin power like a muuuhh facka
