Is there anything i should know before using one of these on a 1JZ? It's going on a automatic transmissioned car. HP goals right now are not big, i just want it to run good.

It would rock it nicely. Very nice turbo with good response. Hard to go wrong with it, unless you stepped up to a GT40R.

Ive been stressing my stock twins HARD (20+psi), i can imagine they wont last but another month or so. I'll be putting this on detuned for a while til i get everything to handle the hp.

IS that a good street turbo to have? I mean where I don't have to wait for 4000rpm to even make a turbo spool...

I would say on a stock 1jz with only basic fuel mods and free flow exhaust and daily driven car..

that turbo is smaller then a sp67... 67 is laggier but has a bigger compressor wheel

The car won't be stock fuel or cammed. It just wont be tuned for 30psi for a while.

highly doubt it... 67 is laggier but will make more power by far.

67's have hit 700 WHP which is insano power.
