    Conversion from NA to SUPERCHARGED NOT Turbo....

    No documented build, but I did look into this rather extensively. The GE's electronics package is not suitable for forced aspiration. (It can be done, but it's such a pain that I wouldn't bother.) You are far better off going with the turbo ECU and electronics, and with that, you're better off...

    7MGTE upgraded (550/57 trim) CLUTCH question...

    I was too old to do silly things in residential areas when I was 16. That's what the industrial parks were for. :D The stage 1 that I had was indistinguishable from the stock clutch to me, and I was comparing that to the stock W58 clutch at that. Objectively, I know that there was more pedal...

    block machining question

    TSRM Page EM-68 Remove the rear oil seal retainer, remove the oil pump driveshaft, remove the lower timing cover (The one that gets decked with the block), remove the oil pump, then remove the mains, and the crankshaft lifts out. Don't remove the main caps until the last step. Good call on that.

    7MGTE upgraded (550/57 trim) CLUTCH question...

    Whoops. That's the one that I meant, instead of the extreme one that I linked. It should be fine for what you want.

    7MGTE upgraded (550/57 trim) CLUTCH question...

    I had a spec stage 1, and with the 60-1 turbo at 16 psi, it let go at 4000 RPM. It stank in the car for 2 days, and the clutch was toast. Flywheel cracked, generally didn't look very pretty. It did last about 3 years before this, though, so it's not like it was ALL bad. I went straight the the...

    7MGTE upgraded (550/57 trim) CLUTCH question...

    ACT Stage 2 clutch. Very streetable. Really, I'm using the Stage 3 kit and am having no problems with engagement. I've never had it chatter, and can drive in a civilized manner on the street.

    block machining question

    The tolerances on the crank are tiny. I wouldn't polish it myself. It's cheap enough,a nd you'll have the block into a machine shop anyway, so just get it done. Get the block magnafluxed first. Some people have still had issues come up after, but it SHOULD catch any issues that you didn't spot...

    Gaskets & Fuel Question

    Heh. If you're asking if you need the 400lph, then the answer is: "You don't." You'll know that you need it because you'll have to do some serious building and tuning on a 3L engine to get there. The 255lph in-tank kit is your best bet, and it will have what you need to install it and have it...

    Help removing turbo knuckle

    PB blaster/WD40 doesn't burn hot enough to be a problem, though you won't want to have it in the car.

    Gaskets & Fuel Question

    There is a Walbro in-tank pump as well as an in-line pump. The in-line pump will also work for you, and won't require you to drop the tank, but will require some creativity to install. I'm using an old, "tired" pump with my turbo engine, and it's keeping fuel pressure just fine. (Nearly half a...

    BHG repaired, crank but no start.. no injector pulse.

    FYI, there are 2 very similar looking resistors. One is for the fuel pump, and it's on the right side tower. Both GE and GTE will have that one. The other is on the left tower, and is for the injectors. The heat sinks look the same, but the GE car will not have the second one. The mounting...

    BHG repaired, crank but no start.. no injector pulse.

    7M-GE has no resistor pack for the injectors, since it uses high impedance injectors. I had to install one on my NA-GTE conversion. The Haynes manual isn't keeping the info straight between the turbo and NA models. Go to the on-line TSRM, it will be a much better resource for you, including...

    What did you do to your supra today? Pics

    I really hate problems that go away by themselves, because I'm always waiting for them to come back by themselves.

    Help removing turbo knuckle

    Lots of penetrating oil. If you don't want to pound on it any harder, go buy a 5" bench vise and a triangular file. Put the point of the triangular file so that it's a wedge between the turbo hotside and the elbow. Put it in the bench vise, and use a snipe to crank on the vise handle.

    brass flakes in oil pan..just bearings

    No way to know until you pull the crank, but if there's no noticeable knock, then I feel that it's likely that your crank will get by with a polish.

    Furious But Lazy 7M owner who gave Up.

    Problem with taking them to court is that you have to find someone who is willing to testify that they did something wrong, and can help prove it. I've always had the experience of shops being very careful about pointing fingers about stuff done wrong, no matter how clear-cut it seems to be that...

    Engine swapping from Turbo to NA car

    Addendum. '89 is its own special year. The ECU is NOT compatible with the '90+. It's grey plug, but actually closer to the yellow plug harness from the pre'89 cars than it is to the grey plug '90+ cars. They hellow plug engine harness will plug into the chassis harness, though with minor...

    Full 3 inch exhaust system causes fuel cut?

    "losing power" is kind of an ambiguous term. I've only felt FCO in my car once, and that was quite the experience. I thought for sure something had failed. It was only after fuel was returned, that I figured out what happened from others' descriptions. Probably a different experience in a...

    EGR Revival question

    This. There is no reasonable explanation for heat buildup in the head from an EGR delete, except for the potential increase in EGT, which NO delete system can prevent. This is also only under part throttle where this can happen, since that's the only time that the TCCS should have the EGR...

    Furious But Lazy 7M owner who gave Up.

    Well, I guess that I don't feel so bad that the machine shop that I took my 7M to didn't do any assembly. It does mean though that if anything goes wrong it's my own damned fault... In that video, the first few seconds sound EXACTLY like the 7M that I'm pulling out, in which I'm expecting to...
