Turbo Problem
 

I'm pretty sure somewhere out there, there is a thread already about this, but I don't care...because its 8 am, and I haven't been to sleep.

My 88 Supurbo yes I combined them. Is not wanting to release the pressure built up by the turbo. Which means, I have tons of acceleration, but it's a horrible air/gas ratio, and the engine isn't wanting to spit out as much gas as the turbo is air. It's going to 8 psi and dumping, then itll repeat until i let the gas off. No I don't sit there and do that...I rarely get it up to 8, but I can't do anything for real in it.

I think the wastegate might be stuck, if so I'm going to order a new wastegate...so if anyone could help me with this problem I would be glad to say thanks, and help out with what knowledge i have.

If it is the wastegate, what is the site that offers stock supra parts and OEM ones. It's not a very well built website, but it is high trusted and I can't find it anymore... =(:werd:

Mklll don't come with wastegates. I think you're referring to a blow off valve. It could be stuck closed which will cause a large amount of pressure build up in your pipes.

You are dead wrong.... the CT-26 uses and internal wastegate. The wastegate actuator is the round metal can with the rod coming out that is mounted to the CT-26.

BOVs do not vent from boost; They vent when the actuator sees vacuum. They are not a device for controlling boost levels.

Cyto, wastegate actuators are generally not cheap. I would start with trying to find a used one to swap in. Have you actually tested the wastegate to see if it is likely that it's sticking?

When the HG blew, he had to take everything off, when he put it back together, he found out that water had gotten in the exhaust and melted the honeycomb in the Cat, at first he thought it was the wastegate. The problem: not wanting to rev up.
Solution: Gutting the Cat of everything(straight pipe down the back now).

Utter bullshit. Water is always flowing past the cat, it's a natural byproduct of the combustion process... besides, ceramic, platinum, manganese, iron, nickel, palladium and rhodium are not water soluble and all have a much higher melting/burning point than water could ever achieve...

All that was said by a local mechanic, I figured it was stupid. I didn't question it though, however; he did completely strip everything out of the converter.
I'm not too car savvy, so bare with me? lol

I wasn't questioning your intelligence... I was pointing out that that remark was either based in pure ignorance or it was a complete fabrication for who knows what reason.

Its k, he's a drunk redneck... So you're not offending me in any way...

Actually BOVs do vent boost. Waste gates prevents boost from occurring by venting exhaust gas from the turbo fin.

You'd have high boost lag if your turbo was running full boost. You'd have high acceleration if your BOV was stuck closed.
