Just do your self a favor and go t3 .48/.60 , quick boost strong all the way to shift with a turbo thats meant for it ;-)

a .48/.42 vs a t3/t4 is like night and day at the boost youre running on that motor. Id say your running it on the ragged edge of its efficiency right now. Even a t3 60/63 would be a huge step up.

Oh yeah copy pasted this from g2ic turbo giude-[As opposed to exhaust system diameters where bigger is better, here bigger is definitely not better. The larger the pipes are, and the longer the pipes are (plus the larger the intercooler) the more volume the turbo will have to fill with air before it becomes pressurized, creating lag. But there is another side to the coin. If the pipes are to small they can prevent sufficient air volume from reaching the engine even though the turbo is more than capable of providing the required volume. Generally 2.25" is good to about 400 horsepower.

charge piping is a good top end maker in larger size, so it was a very applicable suggestion. Sure that 400hp car on 2.25" charge pipe might rip nice, but change that same setup to 2.5" and I bet it'd make more.
If you want another suggestion, you might look into intake mani, larger throttle body, and some headwork/cams.

Honestly just get a cheap dry nitrous kit and jet small.Tune your a/f richer to compensate when its activated.A small 10-25 shot will give you the topend you need till you upgrade the turbo.Ive used it before on my own cars and other dsms.Works very well.

Thanks for the replies to those that did.What Im most likly going to do is sell my t3 either here or on ebay then use that money to put towards a new or good used condition t3/t4.I wont get around to this until late august.Maybe get some sweet charge piping and a new wastegate while im at it.Anyone know where I can find a nice 2.5" charge pipe kit cheap as dirt?Also trying to find an uberdata tuner in the south Florida area.
