Its eather the gauge or sending unit. On a single wire unit,if you ground the wire ,the gauge will max out.This means the unit is bad. I hope this helps.

1987 Supra What is the in-dash warning light left of the temp guage? symbol: carriage light, filter?


Radiator, usually comes on when the exterior plastic tank gets low . Sometimes these leak as a result from low antifreeze and the plastic tank will crac k at the base, where the wire comes out which activates the little symbol light to the left of the temp gauge you are referring to.

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?


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.

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.

Temperature needle jumps.


check the connector at the temp gauge sending unit, it may be corroded, engine movement causes the connection to make and break and this gives the fluctuation in the needle of the gauge..
