The cheaper parts (with lower part numbers) are typically obsolete. The prices reflect the fact that the last time they sold the obsolete one was years ago. Toyota often updates parts over the life of the car, and the newer part number with a higher value in the last 2 digits is typically the...

Had the same problem with my original Toyota CD player. The electrolytic caps dry up after 16+ years. Its a major amount of work to replace them since those old CD playes are a jumble of circuit boards and wires. Even after I replaced them my player skipped badly and I eventually tossed it...

Thanks! The things that seem to be missing to me are the turbo water/oil line gaskets, the water bypass pipe to thermostat housing gasket, and the EGR gaskets. Plus some of the gaskets on the intake for ISC, throttle body, and so on. I was going to order those if they are not included, but I'd...

I am trying to find out what's included in the Toyota Valve grind kit p/n 04112-42023. Based upon the parts catalog illustration I came up with the following list. Can anyone confirm? valve grind gasket kit contents 1 90301-07001 6 fuel injector o-ring 2 90430-14007 1 Gasket, Pipe...

Running out of ideas here. Has the car ever run properly since you got it? Maybe it has turbo injectors (440cc) instead of the NA injectors. Otherwise, looks like time to find an NA ECU. Have you tried disconnecting the battery for 30 minutes to reset the ECU?

Sheesh, I need to read more carefully. Okay, how about the cold start injector. Not likely to be the problem given that you are holding fuel pressure, but if it comes on you will have a severely rich condition. I would also check the cam timing to make sure you haven't skipped a tooth on the...

Please test the TPS and let us know if its okay. Also check that VTA-E1 resistance varies smoothly with throttle angle. I am wondering if the TPS is giving the ECU a WOT signal when it is not. http://www.cygnusx1.net/supra/library/TSRM/fi/FI_101.html

Umm, the tachometers are different between the GE and GTE. You can either swap them, or change some resistors. http://www.autosoftsys.com/supra/tachcompare/

If the head gasket was going go, then it doesn't matter who was driving. You don't break-in a head gasket like a set of rings! :icon_conf

You can start with this paper that explains the Torsen in great detail and compares to conventional differentials. It is by no means the nice tight summary you are asking for, but if you put in the effort you will come out knowing a great deal more about what a Torsen diff is all about...

Yeah, sorry about that. Boostin88T is your coilpack moved somewhere else?

You can replace plug #2 without removing the coilpack?

If the seal is old, it is certainly bad. They get baked hard in the exhaust side of the head. If the seal is new, then it may have been damaged during assembly, or you have a leak through the cam bearing shell like Johnathan said. Note that the bearing shell needs FIPG goop applied during...

If it doesn't go full firm on braking above 37mph then you have a problem. Follow the diagnostic procedure in the TSRM. http://www.cygnusx1.net/supra/library/TSRM/fa/FA_34.html

First thing to consider is if your battery cable incident caused any damage. Since a lot of current probably for a few seconds you would want to make sure all the ground straps on the engine are still functional. You could have melted some of the smaller ones like the one from the firewall to...

Should go full firm when braking above 37 mph (60 km/h).

Jetjock, have you passed ASM5015/5025 without the precat? I've got one coming up and would rather not put the stock DP back in. The Supra seems to be classified as a high emitter in CA these days, so I expect more scrutiny than normal.

The issue is not a warped surface, but the average surface roughness as defined by the the Ra number. Roughness is measured by special precision instruments that measure the vertical deviations when traversing the metal surface. Ra is the most commonly used parameter to describe the average...

The stock head bolts are reusable per the TSRM. Note that non-reusable parts are clearly indicated by a black diamond on this page of the TSRM. http://www.cygnusx1.net/supra/library/TSRM/em/EM_32.html Also note that the factory recommended torque on the head bolts is 58ft-lbs. I am...
