    Wheel Fitment & Question Thread

    Coil overs for these cars are always small skinnier and lighter. You can gain about 1-2inches of space from just switching from spring/ shock to coil overs. Also just for kicks. My old coil overs seemed to weigh about 30lbs or so. My bilstein and eibachs felt like 70lbs. Just a guess from...

    Bolt on Big Brake Kit For around 300$.

    Your using the wrong bolts. Mercedes has 2 bolts. The fat ones and the skinny ones. You need the skinny ones. There 4mm thinner than the mercedes calipers. The mercedes calipers are 32mm new and min thickness is 30mm.

    Bolt on Big Brake Kit For around 300$.

    how did they not center the rotor good? I used the plastic ones on 2 cars. i had to sand them down a little bit to get them to fit easier as they were a tight fit.

    You have to wire up the body plugs in the same way the non digital cluster is wired up.

    So many options to choose from. MS3? Haltech? AEM? Something else?

    Aem v2 is a lost cause. Barely got flex fuel late last year when it was supposed to have had it when it came out. Support for it is basically done and aem has moved away from it to the infinity.

    most problems with megasquirt are user inflicted. especially true with the ms2 as it takes quite a bit of hard ware config. ms3 pro is super easy to deal with same as ms3 with 3x. I do not have experience with haltech sorry.

    2jz na-t cuts out

    Yes but your running 850cc Injectors with likely a 550cc injector chip with the Vpc. For example a 550cc Injector would want say 4ms pulse width at idle. The 850 will only want 2ms. And same goes for entire range of rpm. That setup is a bit wrong.

    Help me convince my Dad to buy an MK3 Supra! [PROBLEM] {LONG}

    The radiator is about to pop. And once it does it's likely the head gasket will go with it. Also looks like everything steel is rusting. If the rest of the car is too not worth it.

    So many options to choose from. MS3? Haltech? AEM? Something else?

    A flex fuel sensor only measures the ethanol content in the fuel. So it cannot tell if you are using 87 or 110 gas. It can tell you if your using gas or ethanol or anything between tho. Imo i would skip looking into an aem v2. I havnt dealt with the infinity which is supposed to be nice...

    2jz na-t cuts out

    51 is tps. check that first. Second the na fuel regulator is not a rising rate fuel regulator. turbo regulators increase 1 psi of fp for 1 psi of boost. na do not.

    MHG Leaking?

    Sounds more like improper build. If it had an older design of head gasket some of the rivets need to be drilled out as they interfere with sealing.

    headlight not actuating

    http://www.cygnusx1.net/supra/Library/TEWD/MK3/manual.aspx?S=Main&P=060 Check continuity from connector to integration relay. If wiring checks out the it has to be the integration relay for retract control or the motor. They have common power, signal, and ground.

    Higher oil PSI?

    Also it's best to replace the squirters bolts. They lose tension over time and start opening very early.
