  1. A90 Supra Chassis Codes DB42, DB02 VS DB4A Coilovers

    Not sure if it helps but AFAIK the 6 port cars here in the Middle East are DB01 IIRC. I might be remembering incorrectly.
  2. Seeking Opinions on Valve Covers for My Engine Build

    AFAIK, the only aftermarket valve cover is the aluminum VTT one, and I guess Visconti that deletes or deletes the stock PCV from the valve cover. Some people have run the VTT valve cover just fine, but it requires catch cans to vent PCV and CCV.
  3. V8 MKV Supra will compete in Australian Supercars series

    It looks really similar to the GT300 Supra platform chassis wise
  4. Toyota Deutschland announces GR Supra Convertible!

    Not so bad. Liked the Targa too better, but I’d imagine this is probably easier to manufacture on a mass scale.
  5. New 2025 High-performance A90 Final Edition announced for JP/EU/AU (No GRMN - S58)

    It shouldn't be too hard, BMW guys have been doing it for a while. The only issue is that it might require an FSC. If it does, out of luck. Can't flash it over the DME with E-Sys if it requires an FSC. If it doesn't though, it'll be a cool OEM plus tune that doesn't really void the warrantee for...
  6. Stainless Steel Exhaust Identification + Dual Valve Question

    Steel 'clone' or of the Boostlogic exhaust. Same thing as the GTHaus one swrdply400mrelay mentioned (GTHaus are just rebranded Alibaba exhausts). https://www.supramkv.com/threads/aliexpress-exhaust.10490/
  7. Should I add CSF coolers or not

    Supposedly CSF kit does not reduce heat soak as much if at all compared to stock. Only reason you see it everywhere is because they send it to ā€˜influencers’ for free on builds. if you *had* to get a new heat exchanger for whatever I’d probably say PWR, or maybe Forge. I haven’t changed mine...
  8. When to build the motor? Advice on drivetrain upgrades on MT? Cooling recs? Anyone running pure 900 ? Random wheel question

    Yeah, the general use is that they hold more clutches but also in high torque application, the cast aluminum E hubs tend to break when launched. I think in track applications it’s fine. E clutch hub on the autos fail when launched with high torque. There’s a few references of it happening on...
  9. When to build the motor? Advice on drivetrain upgrades on MT? Cooling recs? Anyone running pure 900 ? Random wheel question

    Pure and ATS trans upgrades are auto only, not intended for manual. For reference though to answer the question, they replace the failure prone E and C clutch hubs, added friction discs on C and E to hold torque, and machined pistons to accommodate clearance.
  10. Best Race Seats

    My car only threw the airbag error, I didn’t have to code out the seat position for whatever reason. I ran resistors for a while until I needed to code out the drivers wheel airbag for something else. 3.3 1 watt works fine but you’ll still have a restraint error if your car has the seat...
  11. Best Race Seats

    I swapped my stock seats out for a set of Bride seats. In my opinion more pronounced bolsters, as well as a lower seating position was a nice quality of life change on auto cross and spirited drives. The stock seats are fine though. I think the only annoying thing is how the headrest is...
  12. 600 RWHP what’s needed? Future proof & cheap way

    AFAIK Probably have to go big turbo on something like MS109 since it’s more energy dense. Be it stock frame or aftermarket. As a general principle, you add more ethanol to increase octane when pushing a turbo out of its efficiency range. The more ethanol you’re running means the more your...
  13. Why isn’t MG Flasher more popular?

    Reflex integration with Custom Code recently dropped on MG Flasher. Will move over to a custom tune and Reflex with PI sometime soon and report my results.
  14. Has anyone switched this bar out?

    Anyone have an idea where the lower bar bolts into? Assuming top part either goes where the factory bar goes, either Cusco or USM, but I can't figure out if the bottom part bolts into existing places, or if Toyota/BMW added a dedicated spot for it.
  15. IF iT WaS A rEAL ToYOTa, thE SuPRa wOULD'vE BeEn BeTTeR..

    It’s pushing 100hp per cylinder on the 3 cyl GRC that runs about 20+ psi boost. The car is going to be octane limited with little headroom. Anyway I don’t get why people still dog on the Supra for being a ā€˜BMW’. The G series are boats. The Supra is the lightest and cheapest B58 platform to get...
  16. Garrett G35-1050

    AFAIK only one currently selling an IWG kit is Big Boost. Doc Race also had EFR but as long as you're using a T4 turbo it should still work minus the downpipe v-band. They supposedly are willing to sell the old EFR EWG kits but they ghosted me twice on further inquiry. Anyway, any regular turbo...
  17. Unlocking ECU through middleman or send it straight to FEMTO

    I get the sentiment of the earlier days when the Femto unlock process was still really new, and the only way of getting a hold of femto was through their Instagram. It seems a lot more reassuring to send your DME to essentially get hand delivered, than by courier to an address dropped on...
  18. New 2025 High-performance A90 Final Edition announced for JP/EU/AU (No GRMN - S58)

    Still kind of cool, essentially a road legal Supra GT4.
  19. Aliexpress B58 Gen2 Manifolds??

    No quantitative data. Useful in particular other than that the IATs were low enough to switch from using meth kits for cooling. That, and nothing has failed yet. Definitely hyped to see OPs experience on the manifold assuming it’s not a shill.
  20. Aliexpress B58 Gen2 Manifolds??

    A couple of guys out here run the manifold, no one has mentioned any sort of bad effects coming from them. Don’t know if I would take the risk of any of the welds failing on a W2A integrated manifold/intercooler.
