    Rear diff ratio decision

    Hello all, It's been a long time since I've posted here. I recently noticed that Driftmotion.com sells rebuild/upgrade ring and pinion kits for our mk3 supras. A few years ago I was trying to find a replacement ring and pinion with no luck. Since DM.com now has these in many different...

    A/C inop after electric fan conversion

    Hello everyone, I haven't been active on here for years, but I'm hoping someone might have a solution to my issue. Probably 4-5 years ago I installed and wired in some electric fans to a switching thermistor. The fans have been working wonderfully for cooling the car, they turn on and off when...

    Thermoswitches for electric fan operation

    I'm installing two electric cooling fans soon, and would like to have both fans switched on/off independently with (more than likely) two thermoswitches in the thermostat housing. I've been searching for what on/off temperatures would be appropriate, and also if there are thermoswitches...

    Help understanding BC 264 timing card.

    I emailed BC to get a hold of another copy of the timing tag for my BC 264 cams. I'm trying to understand it.... It looks like the exhaust valve opens at 48 deg before BDC, and then closes at -8 deg before TDC (why didn't they just put 8 deg after TDC) and the intake valve opens right at...

    Spark plug "holder" or retainer part search

    I'm currently in the process of finishing up a 7mgte build, and am running into some trouble finding some parts. I'm looking for the clips that hold the spark plug wires to the coils.

    Choosing piston brand and other internal engine components

    I recently purchased a spare 7mgte block and head with the plans of building it up to handle 500+hp. I am currently running around in a rebuilt 7m, but I had built it when I was 17, and wish I had done things a little differently. (Didn't do anything aftermarket with the head in terms of...

    Loss of power...trying to find boost leak

    This past spring I installed a sp61gtbb and bc 264 cams. After that the car felt great. But now the car will barely spin in 1st gear, and the car overall just feels... weak, completely different. This seemed to be more of a gradual change. I suspected a boost leak, so i made a tester and...

    Part Throttle Tracking Maft-Pro, CEL

    So inorder for the car to stay in open loop, the oxygen sensor signal has to be removed from the ecu. But after doing that, you'll be running around with a check engine light on constantly... Is there any other way to make this work while keeping all the danger lights off? Thanks, -Alex

    another maftpro issue, crank/no-start

    This past weekend I tried starting my car for the first time on the maftpro/speed density setup. It sputtered a little, after that, it would just crank and crank... After thinking for a while, I remembered that I didn't adjust the mainscale to compensate for the 550s I have in it...So I pulled...
