  1. What would be a safe amount of boost

    MKIV (1993-1998)
    Depends on compression ratio, octane with meth and rev limit? If stock 8.5 you can probably run up to 25psi around 600whp. I'd recommend having your tuner take care of that info for you. If it's just a drag racing car maybe you can run even higher boost pass after pass.
  2. I can build MKV to be an amazing machine.

    2020+ Toyota Supra General Discussions
    Codes and lights shouldnt be an issue because it's a BMW ECU that gets used in half their cars. Programming it for a manual 6 speed is easy if you know how to work with their systems. The gear ratio will be long though, 1st gear to 40mph 2nd to 75, 3rd to 110, 4th to 150. Changeable by the final...

    Yeah using a transmission that's already used for the B series would be the way to go. Maybe even the S55 trans although its more expensive. The swap that was already done probably cost about 3k. A couple grand for the trans and clutch combined and then the small BMW parts like shifter boot and...
  4. Second Borg Warner turbo warped turbine housing - heat

    General Supra Forum
    If you do eventually change turbos check out the new Garrett G30 series. Fully stainless steel and Mar-M alloy for higher temp tolerance and long term use. Great job and that heat shield too!! Looks similar to what AMG uses on their M139 engine
  5. What’s the problem with MK5 ?

    2020+ A90 Toyota Supra News
    It's a BMW ZF tranny specially made for their modular B series engines. They pulled it from a 520d I believe but had custom make the clutch pedal box to fit under the dash. The driveshaft had to be extended 3 inches and the shifter linkage 2 inches as well to sit back far enough. It's a small...

    This is part 4 of the build. Soon to be at SEMA so thumbs up on getting it done to these guys.
  7. 2JZ-GE oil temperature

    MKIV Technical
    Perhaps its type of sensor or sensor location too? Inline vs sump or turbo side of the block? If it's not shielded and you live in a hot climate, seeing 100 to 115C in stop and go crawling traffic is possible. Engine bay heat is not identical for every car depending on the shrouding and stock vs...
  8. A90 MKV Supra exhaust systems

    2020+ Toyota Supra General Discussions
    I had no clue the UK Launch editions were 1 in 24. The aftermarket exhausts sound okay but the extra pops seem so annoying after a while -_- The garage though with the Ford GT and McLaren Senna 🔥🔥🔥
  9. Built motor and built head - What cams ?

    MKIV (1993-1998)
    Yes 9.9 is interference. Over 9.5mm is actually if i recall correctly. GSC S1 cams would be fine for your power goal. S2 will get you past them if you plan to rev above 9k RPM but you will probably lose some torque at low RPMS. Especially if you're still on a low compression motor.
  10. Second Borg Warner turbo warped turbine housing - heat

    General Supra Forum
    Upping the boost will give you more midrange but the torque drops off up top still instead of staying steady to redline. Power is still there which is great but the turbine is an issue regardless.
  11. Second Borg Warner turbo warped turbine housing - heat

    General Supra Forum
    My guess is you have a 74mm turbine with the .91 twin scroll? So you're 6 up from the bottom here. It's for quick response which you have but over 6k RPM it can't breath. Probably why you need meth to keep it going up top. It just can't get all the heat out effectively while your pumping all...
  12. Second Borg Warner turbo warped turbine housing - heat

    General Supra Forum
    Not just Xona, Garrett too. In case you've never looked at the turbine maps for BW, they are NOT designed for high rpm use on those old models. They really fall off up top as everyone knows. A larger A/R would help but 8k is still too much on an inefficient turbine. Precision doesn't show maps...
  13. Supra First Drives are in... add them below

    2020+ Toyota Supra General Discussions
    Virginia International Raceway. Its a nice sized track but the Supra seems to come up quite short of expectations for a 2 seater pure sports car. 5 seconds slower than the Porsche Caymen GTS and 3 seconds slower than the Audi TTRS. Luckily it does does surpass the WRX and Civic type R by a...
  14. jakie wrecks his zupr4

    2020+ Toyota Supra General Discussions
    That's some interesting info on the base model. I wonder if he will make sure this one is completely track eady for Buttonwillow finals. We know what happened last time when he used poor tires for too long, now he might need a brake upgrade too
  15. Let's break down the MKV Supra's Engine (B58B3001)

    2020+ Toyota Supra General Discussions
    Yes, 6 individual exhaust ports and twin scrollish log manifold. Completely different from the small 2 port non rotary head Toyota uses. This is OEM vs aftermarket which gets used on builds with larger than stock frame turbos
