To clarify a couple things...10psi was at 3500, full was at 3800-3900. The lag is not at all what I expected, and that was also on a stock ported manifold w/ a t4 flange welded on...I'm running a full tubular, way higher comp so I should spool it up a bit quicker even.
With that said, the turbo doesn't even get in it's efficiency range until 15psi+. The difference between 15 and 18psi is HUGE...You can do over 500rwhp on pump gas easily with this turbo if you tune it right.
I did 450 hp and 418 tq @ the wheels at 16 psi on our Dynojet after I went back and took the smoothing off the graph. From 3000 to 4800 rpm the car jumped 300 rwhp. My turbo specs are an SP67GT with a .68 a/r and a p trim with a full 4 inch exhaust system and an HKS cast long runner manifold.
I think the PT67 would be a great match for the 7M motor. Based on dyno results, it looks like the stock head and cams on the 7M start to run out of flow in the low 600rwhp range. This is right where the PT67 is making very efficient power. Sure, your turbo will need a few more hundred rpm to spool compared to a 61mm, but this turbo is considered a baby to MK4 guys. And, I bet its the hot ticket to running some 10 second 1/4 mile times with a 5sp.
I just bought a PTE67 for my car. I'll be running it on an HKS long tube manifold. I also have a built head so it should make good power. Something else you have to remember is say you want to do 400 or 500rwhp the 67 will do it at a much lower boost than a smaller turbo allowing for more power on pump gas with less heat.
so, what is an optimal exhuast housing and exhaust wheel to eclipse the 600 whp mark (at high boost, of course) while still mainting relatively fast spool. I really like that full boost by 3800 to 4k rpms idea, and my motor, ems, and fuel are good to at least 600 whp at over 28 psi of boost
I have been on the search for the thermostat housing or water outlet as toyota calls its, I just need to front piece that goes between the thermostat and the radiator not the piece that is bolted to the block please message me or comment if anyone has a spare for sale It would be much...
its hard to find a true clean MKIII anymore. i'm sick of going out on weekends and all you see is a million big talkers with their little vtec/si civics, accords, integras and when you do find a supra its usually rusted up the wazoo, falling apart or destroyed cause somebody tried to rice it...
so these are my plans i plan to get straight exhaust, cold intake,performance headers,performance cams,performance ignition kit,plugs wires coil,,,,,,,,turbo controler and what else..... simple cheap things less than 500 dollars, ive heard that people turn in their ecus to have chips added to...
Hey all, I'm repairing my harness and I'm trying to figure out which connectors I need for the various sensors on the thermostat housing; mainly the two A/C water temp. sensors (light green/red and blue/white wires). If anyone can snap me a quick pic I would appreciate it MUCHO.
Can anyone tell me where is the fuel filter located on a 1987 toyota supra turbo. The manual states it is next to the starter. The dealer states it is under the intake manifold. But I still can't find it.
