    Voltage Drop, what should i do?

    There is a high-amperage MR2 alternator available for the MR2s with electric power steering. Unfortunately the case is much larger than stock, and interferes with the 7M crankcase vent hose behind it. The terminal positions are also rotated and that requires some rewiring.

    Too much torque?

    If anyone thinks torque = energy then they either flunked their junior physics class, or never took one to begin with.

    audio help!

    Some have an external amp under the passenger seat. If yours does, you will find the standard Toyota 6 and 10 pin plugs there. This set up is pretty much used on almost all Toyota cars except for the upper end models. Adapters are everywhere to convert the 6/10 plugs to aftermarket radios...

    Emissions help

    Rich indeed at 8.99:1. It is interesting to note that 440/750 * 14.71 = 8.63 (compare with 8.99) I suggest going back to 440s to pass.

    Help...Confusing coolant problem

    Here's a real simple test. Squeeze the upper rad hose and check if any coolant flows into the reservoir. If it does, you have a bad or incorrect rad cap (there are two caps, and the 90+ cap does not work with the older style 86-89 rads. All aftermarkets I've seen use the old style cap. Hope...

    Air bag light

    The SRS system is well designed, and not that hard to troubleshoot. The biggest problem with it is the confusing documentation in the TSRM. Start by reading the codes. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=AB&P=29 If you get a code 41 then the problem, whatever it...

    Alternator and Tire concerns

    High resistance at the connector. Remove the connector (its a nut) and clean all the surfaces, then reinstall.

    ebay recirculated DDP - fitment and specs?

    At the cat end, the position is defined by the hanger, so it is basically the stock centerline, except the pipe is bigger so that pushes it a little closer to the body.

    Testing VF,confusing results...

    Since the ECU is open loop and not setting any codes, it must not be trying to run in closed-loop mode. Perhaps it is stuck in warm-up mode. This can happen if the water-temp sensor is bad, or the thermostat is stuck open and the engine never warms up.

    fumoto valve

    I've got those on all my cars now. Got the ones with the nipple so that I can run a hose straight into my drain tank for zero mess. If your present plug is dripping, your flange probably has a dent in it from some jiffy-lube monkey over-torquing the drain bolt. There is a cutout in the...
