    Boost leak - compressor to oil passage

    Not the high pressure supply - the drain passages.

    Boost leak - compressor to oil passage

    After some reading around, Im pretty convinced that the amount of leakage Im witnessing is normal, and in fact helps prevent oil leakage into the housings.
  3. Yo. Im sorting out a few boost leaks, and one of them is between the compressor housing and the turbos internal oil passages. With a tester attached to the turbo inlet and the rest of the intake piping capped off (disconnected from the engine), I can see oil being pushed through the turbo drain into the sump (I have a transparent hose, so can easily see this). This is a TD05HR. Is this normal? Or do I have a problem?

    AW11 MR2 with thin flywheel

    Ended up solving it by ditching the vacuum bleeder and using the pedal to create pressure instead. No more air bubbles, now goes into gear. Still using the longer slave rod, though. I know the best solution will be to space out the pivot, but tbh I would rather avoid taking the gearbox off! Another day.

    AW11 MR2 with thin flywheel

    Thanks guys. I made various lengths of rod out of old head bolts - some improved the feel, and I actually got it into reverse, but I could feel the car wanting to roll backwards when letting off the brake, so it's almost there, but not quite. Doesn't want to go into any forward gear at all. Going to have to adjust the pivot, space it out. That requires dropping the gearbox, which really sucks.

    AW11 MR2 with thin flywheel

    Hey. Ive installed a thin and lightweight flywheel in my MR2. Its definitely a 4AGE flywheel, but is about 10mm thinner than the factory unit. Ive bolted it up and throw the gearbox on my turbo engine and bolted the whole thing in, but upon bleeding my clutch lines I find that the slave cylinder actuator rod is not engaging the clutch at all. There is slop in the clutch fork - I can push it forward until it finally makes contact with the clutch, and at that point there is a 10mm gap between the fork and the rod. Obviously I could take the engine/gearbox out again and throw on a factory flywheel, but there has to be a way to get this working. Any ideas, gents?

    DIY Fuel injection thread.

    Hi guys. Over the past 8 years Ive gotten progressively deeper into FI, to the point now where I have wired a complete custom system, run via Megasquirt, and learned a lot along the way. Any questions, ask away.

    AW11 flywheel and clutch compatibility

    Im honestly running out of possible explanations, so Im willing to entertain that possibility! Everything looks like it should work. Ill attempt it again, this time in the C56, when I swap engines. And Ill attempt to break it in a bit. Fingers crossed.

    AW11 flywheel and clutch compatibility

    The clutch thickness is pretty much the same as the old one that did work. Hmm. I mock fitted the clutch inside an old C50 I have lying around, and measured the distance from the bellhousing lip to the flywheel gear ring with the clutch fully disengaged (so, sitting on the release bearing), and came out to 16mm. If at all possible, can someone check this for me with a working clutch? Curious if its different.

    AW11 flywheel and clutch compatibility

    Ill check that with an old clutch I have sitting around that definitely fits - thanks.

    Could you elaborate on the offset to the fingers of the pressure plate, and how that could cause problems?

    AW11 flywheel and clutch compatibility

    This happened a few years ago, and when it was apparent that it wasnt going to work, we took it off and put the original clutch back in. It is a heavy duty clutch, sourced to go in the turbo project, but because the non-clutch parts came from a few different cars, and some werent known at all, there was some guess work involved. The engine is a 4AGZE smallport from either an AE92 or AE101. The gearbox is the C52 that came with the AW11. The clutch is a 212mm unit, as is the flywheel. The shop asked what engine etc it was for, and so put the kit together with that in mind, including release bearing. Toyota NZ tells me there are two sizes of bearing - 74.15mm and 83.8mm. Its possible the release bearing that was provided was not correct for the application.

    Fuel line flame explosion prevention

    Cool. And to make up the lines with fittings appropriate for an AW11 and pressure tested, Id contact ENZED or some similar shop? Recommendations?
  14. Hi guys. What is the relationship between engine, gearbox, flywheel, and clutch? My 4AGZE smallport was mated to my C52 gearbox through a lightened flywheel and suitable clutch, I presume. It bolts up to the flywheel just fine, and is the right diameter, afaik - 212mm. Everything looks right. When it was installed in the car, the clutch wouldnt disengage fully, and wouldnt let gears be selected. We bled the system over and over to ensure no air in the system, and could not find any. The flywheel is 262mm diameter, with a 212mm clutch surface. It is 27mm wide at the edge, and 9mm wide in the center. What do I need to do to make it work? What do I need to keep in mind when mixing parts from various 4AGE types? Also, I will be swapping the box for a C56 soon. Will this change the math at all?
  15. My car is 32 years old, and I cant imagine the fuel lines have ever been touched. Should I be worried? Fuel is the one thing you do not want ever leaking, especially on an EFI system. Do people upgrade to braided steel lines? Or will regular lines do the job just as well, or better?
