gt25 v3 gt28

IMO, The best one to go with for a stock engine woudl be a GT30R.

so even bigger then what i was going for huh?

it really depends on what you're planning on doing...im autocrossing so i would go with a smaller turbo that spools at low rpms thats why i just bought a 14b which is similar to the gt25...

but if you're planning on drag racing or something similar go with a bigger one...

the gt30 is nice i just dont think i'd take full advantage of it on a small curvy auto-x course

well i am planning with the auto cross thing with some buddies at work. but im a drag racer. so im taking it that the gt28 is simailar to the 16g?

or what about a t series turbo or another simaliar one to these discussed?

How much horse are you looking for? For 300whp, here is the gt3267. Looks like it's a pretty optimal range t/c. (I'm hoping this is the link I saved.)
