I wanna buy this turbo from this guy but i dont know if i should. Its a Small shaft t3/t04b. Garret .58 a/r hot side, Air research .60a/r compressor side with a Stage V wheel. I plan on puttin this on my ls swapped hatch but i dont know if it would be too small? The guy said that it would spool before 4 and thats pretty low. I plan on puttin a vtec head on it later this summer would this turbo be too small?
