anyone know the specs on a T60 turbo with a .63 exhuast housing i believe/the turbo maker said it makes 500 and spools off the line but i want at least 400 to the ground?

 

That exhaust housing is too small go with at least a .81. As far as spooling off the line, You can cure that problem with a 2 step revlimiter so you can produce boost off the line. But my recomendation is stay away from that small exhaust housing. You can definately make 400 RWHP with that turbo.

 

i dont wanna two step i would just use that with my t78

 

AR.63 is a T3 housing. T4 housings are .36/.40/.48./.50/.58/.69/.70/.81/.84/.92/.96/1.00/1.15/1.30/1.32/1.71 and these numbers include N~Q trim with HKS housings thrown into the mix. You will need atleast an AR.81 to get the numbers that you want.

 

He needs to go 1.00

 

what?1.00?my t78 does it with a 96 and is laggy as hell

 

Do you have an exhaust port? If your engine is stock, then go ahead and get an .84 That should definitely do the trick.
