Just seeing if anyone has had any experience with these 2 turbo's. Such as hp numbers @ such and such boost along with when it hit full boost. I'm looking into a PT67 w/.68 hotside with the chance to get a .81 hotside. So if anyone has any imput and hp and anything good about them let me know.

I got a its 67 p trim .70.. it spools quick on my 1jz.. i'm only running 9 psi, but it spools quick... i think my last log i was getting 7 psi (wg would open then creep to 9 psi (.6 bar spring) by 3300-3400 in 4th..

im expecting ~ 480-500 on 18 psi.. we shall see how it plays out though..

ive seen high dynos 500+ at 16-18 psi, but usually they have been q trims.. p trims usually start to choke out and dont give the hp.. at least the few graphs i've seen..

I had a SP67GT on my car with both a .68 and a .81 housing on it for a T4 flange. The turbo had a p trim with a 3 inch v band adaptor on the back of it and a .70 TO4S compressor housing which has the 4 inch inlet and 2.5 discharge. I made 450 rwhp/418 rwtq @ 16 psi,518 rwhp/475 rwtq @ 19 psi, and 557 rwhp/533 rwtq @ 26 psi with the stock intake manifold. I made 525 rwhp/ 470 rwtq @ 19 psi, 604 rwhp/522 rwtq @ 26 psi, and 633 rwhp/544 rwtq @ 29 psi on my front facing intake with the .68 housing and 639 rwhp/ 574 rwtq @ 29 psi with the .81 housing and blowing out spark from 5800 rpm to 6700 rpm. I could have made more power if I could have revved higher and I didn't dyno again after I installed my DLI which fixed the ignition.
