Hey, I was wondering if you could give me some advice ? I have a horsepower goal from somewhere at 350-(450 after the motor is built up). I am wondering if you can suggest a turbo/motor work that will get me in that goal while still making the car a fully daily driver and having it be reliable as well. I am considering the gt 3040, the 2540 , t3/t4 (not sure what trims...too many to choose from, but probably similiar to the one at enjuku), and also the bigt28 from forced performance (i think its less of an options because of horsepower goals, I also thought about the disco potato turbo, but again horsepower goals.

I am wondering if you can give me an idea of the spool ups on these turbos ? I want to be able to use boost fairly like the stock t25 but possibly a little more lag. But i'd like relatively fast spool up because i commute and in the traffic i like a little more power right off the line. I know that you can always downshift to combat turbo lag, but not if ur just trying to daily drive. I want to rev to say 3-4 and shift and have the turbo kickin a little. Maybe you can suggest a different turbo i've not heard of ? and I'm very lost as far as motor work and costs ?

How much of a difference would a BB turbo make as far as spool up versus something like a 450 hp t3/t4?

I've done all my own work on my sr including install, heres my current list of mods, greddy rspl fmic, apex s-afcII, greddy profec b, 3 inch all the way no cat, hks megaflow w/ z32 maf.
