My newly installed ct-26 or something else with my setup is acting up a bit.
For what reason i haven't discover yet my car decides to start boggin down really bad
and and dies. Check engine light is on. It happens after i get on it a little.
I accelerated (not a ridiculous amount honestly..) through an intersection and got up to about 50 mph
and was just going constant 50 or so down the road and it started boggin. I let off the gas and coasted and then shiffted back into 5th and it bogged and died. Assure you i didnt miss shift and kill it. Similar thing happend later that night. with no coasting after it starts to bog. If i let the car sit off for ~5 min it starts up and goes fine.
If i try to start it before i let it sit long enough it bogs up and down around 600 rpm and then dies.
All i have installed is the turbo and all the neccessaries and an oil pressure gauge.

Possible facts that could help diagnosis:

i have the supra mkIII injectors
oil pressure gauge only (got boost gauge today)
no timing or fuel controllers to speak of.
no intercooler. It was about 40 degrees the night it bogged and died.
I haven't driven over 3200 rmp since and it seems to run ok.
At stop lights or signs @ idle the oil pressure reads like 2 psi.


My thoughts.. Turbo wheel is not spinning freely and bogs the exhaust gas and kills the car.
Boost or pressure somewhere is leaking and messing up the whole rhythm of the car.
I can drive the car around like a granny and nothing goes wrong but I didnt turbo my car to
drive slower than I can accelerate on my bicycle. Help!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks, i bet your right. The more i think about it.
I did get some stuff off e-bay but most of the 3sgte part i got from
a guy with a blown alltrac. I'm pretty sick of hearing about how cutting corners will blow your engine. The only way i could have spent more money on this is if i would have bought all the parts from toyota brand new. who the hell is going to do tha? You cant tell me i need a brad new cast iron manifold.
I have a problem and if i put on an intercooler with this problem, im still going to have a problem. I obviously don't know what im doing and all my info comes from these forums. I installed my injectors long before i put a turbo on my car. Now i know that the injectors are fine and not my problem because i tested the car with only that changed. See how that works? If my car actually runs with the necessities. (no intercooler for example) than i know that when the ic is installed its the ic if i have a problem.. I know this is not normal but i just want a basic setup of a car that drive normal. Once i have that then i can get equipment to tune it and then i can drive it like a turboed car. I'm not just slapin' everything together and then stomping my foot to the floor.
Sorry i had to vent.
It just seems that if anyone has a problem on these site eveyone else tells them to not cut corners or there car will blow.

Yeah its probably a vac leak.
