I'm thinking about turboing my 16v...either t3 or combo t3t4 but i have few questions...one...what trim do you suggest? I'm lookin at 57 but the turbo im lookin at ( Garrett T3/T04E Hybrid Turbo ) offers 40 46 50 54 57 60...i don't really know what this trim means...also...A/R...would i be better off running low A/R like 48 or running towards 63? i want my car to be really fast...i care more about top end but i don't want horrible, horrible lag...like boosting for only a few 1000 rpms...i want to be able to be in boost for longer but my main concern is top end so im guessin a higher A/R would be better...also...T4 or T3??? EIP offers both manifolds and i have no clue as to which i wanna use...please any info will help, thanks. oh keep in mind...im a turbo noob!
