Turbo options on a 1JZ 400-450rwhp

[JZA70 R]

had i kept the 1J i would have had the exact same setup but with a 6boost or ETM manifold. With a sweet tune you wont be dissapointed, it will spin 400 without breaking a sweat.

Yeah, that's what I'm aiming for! Will be interesting to see how the tial exhaust make it spool up. Apparently they are so efficient that you can get away with the next size down, not taking that chance though

[JZA70 R]

next size up you mean?

[codez]

i think he means that they are designed to flow so well, that a smaller housing may not be too restrictive

[spiller]

Yeah codez, that's what I meant. Todd, I guess going up would possibly not effect spool as much as it would on a standard Garret housing but no way a 1JZ needs a 1.06 rear.
