Wow, we have had a lot of dumb first posts lately. Like the man said, search, and if your answer isn't found, ask. When asking, you might want to actually give the info needed to answer your question like how much $ you have, what you plan to do with the car, what are your hp goals, etc.

K... I grow weary of hearing turbo sizes called out in "Trim" Because it means next to nothing with no other measurments.

Go to Turbobygarrett.com and read until you have a better understanding of turbo sizing, that might even answer your own question.

You could have a 50 trim t25 that maxes out at 200 hp, or a 50 trim t04e that maxes out at 550 hp. So Yes, get a 50 trim, then tune your nos timing... because thats why your unloading in 3rd... You'll run 9's.

Yeah bro I was wondering which 50 trim your talking about??

How much HP you looking for?What kinda driving/ what are you looking for?Big #'s or better response

Beware you might also blow the welds on your intake manifold. Then a bucket of nuts & bolts will fall out from your floor board. lol :-)
