SOURCE: 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.

SOURCE: 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!

SOURCE: I want more boost out of my stock 87 Supra Turbo.

hey mate,

You can get a aftermarket part for your car called a boost controller there are many different types manual and electric, if you go to your local car parts store and ask for a boost controller there is a type called a bleed valve which works by restricting boost to your actuator which controlls the wastegate causing it to open slower than it usually would therefore creating more horsepower... * BE CAREFUL THO AS STANDARD ENGINES, ESPECIALLY OLDER ONES CANNOT HANDLE MUCH MORE HP THAN THE FACTORY SETTINGS *

SOURCE: What feeds the boost gauge?

The boost gauge is fed by the Turbo. It tells you how much extra air the turbo is putting into your engine. This is turbo ONLY. Usually a little plastic line from the turbo to the gauge.

87 thunderbird turbo coupe misfire from idle until 3g then hitting boost n runs smooth


check that the turbo is actually working at the lower rpms.check to see if it is a variable vane turbo where the vanes for the turbine wheel can be altered to produce boost at lower rpms. The vanes are controlled by a actuator on the turbo and is controlled by a vacuum hose controlled by the ECM. The misfiring may be actually over fuelling ( mixture too rich as the boost is too low for the mixture)

My 88 toyota supra shuts off when it make boost


If you overboost , there is a sensor that shuts off ingition spark to keep you from breaking your engine.
Have you modified the turbo in some way that would have caused an increase in boost ?

What feeds the boost gauge? On my 87 Supra Turbo, my boost gauge isn't working properly. Is it vacuum operated? Or are it's readings supplied by the MAF or MAP?

I want more boost out of my stock 87 Supra Turbo. Not to sound totally clueless, but is there some kind of adjuster on the turbo to turn up? I'm just now leaving the world of carburetors.
