  1. MKIII Technical
    Recently rebuilt the top end of my 89 Supra Turbo starting from the head gasket up. As of now the car has a very strong idle and starts with very little drama and with no assistance from the throttle. The issue arises when you try to give it some rpm in neutral. The car will not react for about...

    Hi! So the past week I accidentally discovered how cheap mk3s are, and since I have been kind of getting bored of my 1.8T vRS and always wanted an 80s japanese sports car/gt, I decided its time to save up and get a supra. So as anyone would do, I typed the engine into google paired with "common...

    I'm in the process of rebuilding my CPS with the driftmotion hall effect sensor kit. Actual rebuild is done, but I want to verify that I'm putting the cam and crank sensors in the proper locations. Kit comes with 2 identical hall effect sensors that are pre-wired to a connector but I just want...

    So I just bought my first mk3 with bhg. The engine was rebuilt 80,000kms ago with the block o’ringed and machined with the head, arp head studs and the oem gasket. Just wondering if anyone else has an o’ringed block and could give me some advice on what head gasket they used? I’ve read that...

    Back in Jan I bought an 89 Turbo parts car for $1,500 for the R154 and diff. Engine was not running at the time. After a few weeks of messing around found the TPS was not right and was the reason it would not run. Car ran good and strong after that. Long story short my plan was to take this...

    My 91 Supra had issues moving from a stop, I would have to put it in Low to get it started then put it in drive after getting up to 2nd gear speed to for it to move without it acting like it would slip from a take off in Drive. I drove it to work (car dealership) and it stopped wanting to move...

    Hey guys! I’m new here and looking to start some mods on my 88 Supra. About to do an oil change soon. So figured I’d do some small things like upgrade the oil cooler and coolant lines to steel braided while the system is drained. But after a little research I’ve come to find the oil cooler...
