made 289whp 241 lb/tq.

Stock rb25, cometic intake, exhaust gaskets, freddy intake manifold, q45 TB. tomei adjustable FPR, 3"downpipe 3.5 inch straight pipe exhaust. thats about it. Using a hallman MBC to turn boost up to 12psi and stock ecu no tune.
anyway it served me well this summer and now its back in the garage for a new HG, head studs, some major chassis modifications and a turbo upgrade. going to go with either nistune or the haltech plugn play ecu. as for turbos. i want decent spool time, it is being used as a drift car, but i also want to be able to get some HP outta it. was looking at this turbo on a local forum for sale. its a precision t3/t4 .60 trim with .63 hotside. wondeirng if that would do me any good on my rb25. if anyone can reccomend me some decent setups i would love to hear some opinons. thanks! will post a snap shot of the dyno sheet soon.

thanks guys! it does seem a lil higher than most and i had checked compression earlier this year it was a even 140 i believe across all 6 cylinders, series 2 motor. anyway about that turbo upgrade.... can anyone recommend me a good one? looking for the possibility of close to 500whp capable. but also something thats going to spool up decently quick. im sure my tune is going to be in the upper 300whp range for next year. i also want to mention im going to still use the cast exhaust manifold with a welded in tial flange inbetween the #3 and 4 runner for a ewg.
