Hey guys im looking to buy a GT30R for my SR20DET but im not sure which a/r turbin houseing to get, the .63 or .82 ?

Dose anyone know when I could expect full boost with these a/r's ?

Would I be loosing much topend if I chose the .63 or would they feel pretty similar ?

Also is there a difference between the GT30R and GT30 ?
Or is it the same thing ? some people put an R on the end and some dont ?

Cheers...

GT30R is the way to go.. the GT30 isnt all that..
T04S comp vs T04E, not to mention the new wheels and bad ass center section (ball bearing)

if u want to make any real power (high 3xx to 4xx+), go with the .82 a/r other wise if you are just looking for fast spool, dont even bother with a GT30R, you may as well get something smaller, perhaps the disco potato would be good for you (GT-28RS), just depends the kind of power u wanna make...

i beleive it reaches full boost at 3500-3800 rpm depending on different conditions..... its good for 475 on the sr20 according to wolf... the compressor flows 53-55 lbs/min...
