which turbo to pick

[slowsupratt]

I'm not sure which one of these two turbos would suite my application the best. The car is mostly going to be a fun toy car which will see very little track time.

Both turbos are precision 67's

1) .58 a/r hot side which is a p-trim

2) .81 a/r hot side which is a q-trim.

I know the first turbo will have a much better spool and the other more top end. I'm not sure which will be better suited to run on a non-track 1jz car. The car has crower 272 small core cams so that makes some of a difference.

turbo #1. Just be sure to save some fuel and stay outta boost

I had a 67 with a .70 p trim.. was a nice setup imo..

Since your not into tracking your car and just having fun wiht it, it will be the quickest spooling option, but still flow good hp up top.. My .70 p trim had power all the way to the limiter (7600) with the crower cams.. Peak power I say was ~ 7200.. but power didn't fall off, just leveled out..

Is a .58 a/r housing to small?

I dont think so, itd probably choke it out on high power.. I'd say with a .58 max of about 600-650 whp..

I have a .58 & I love it. Spools relatively quickly for the size turbo I have.....

I think the .58 is perfect for the 1jz, however it might surge on the 1jz. I know that the t67 .58 will surge on the 2jz, so it might on the 1jz also.

Go big or go home! That's what I think of when I put parts on my Supra. More power= more speed= more fun. Yea sure it will suffer in the lower rpm's but once you hit that boost, you'll be thrown into your seet and the compatition blown away. If it were me; .81 A/R for sure. GO BIG OR GO HOME!!!

Unless the competition is going around corners... Plus I doubt he's going for more than 600 whp anyway.

ended up with turbo #1. Thanks for everyones input.

You wouldn't have like the Q trim... it was a little laggy on my 7m.
