1991 Toyota Supra Turbo

How can I make the turbo blowoff sound louder? I have heard of removing the silencer but I am unable to find anything about this on any forum.

Gotta agree with Noodles on this one.
I saw you turned up your stock turbo to more than 10psi. I've got an 87' and I would love to do the same thing. How'd you do it?

if idle sound is an issue.... then put a bigger turbo on ur engine... smaller turbo means lesser weight which means that even at idle the back pressure will spin ur turbo blades.... if ur turbo is spooning at idle.. it's a good thing most guys aim at doing that... Dont worry...Be happy

Mk3 Supra Turbo Boost Gauge Problems


The gauge is working fine, the turbo will not kick in untill the engine is spinning fast enough, as the turbo is propelled by exaughst from the engine. So, you can drive around normal and never use the turbo, and climb in the gas and spool the turbo up, what you are noticing is called turbo lag, which is the biggest down fall when compaired to superchargers!

Timing Dpecs for Toyota Supra 87 6 cylinder


1987 non-turbo: 10 deg Before Top Dead Center (BTDC) @700 rpm
1987 Turbo: 10 deg BTDC @650 rpm.

To set the timing, you will need to connect a jumper wire between terminals E1 and TE1 on the diagnostic terminal. This diagnostic terminal is located just aft of the engine compartment fuse box. It is a black plastic box marked "diagnostic" on the cover, which flips open to reveal the terminals inside. There is a diagram on the inside of the cover which explains the terminal positions. On the Turbo model, you need to remove the forward section of the engine cover to gain access to the number one spark plug wire.

1991 toyota supra blue smoke from tail pipe when get of the gas


The intake valve guide seals are worn and are letting oil slip by under high engine vacuum--as when you let up on the gas. The only fix is to take the cylinder head off and replace the valve guide seals. This problem is pretty normal for an older car with high mileage. It will probably run just fine. Just keep checking the oil level and keep it topped up.
