  1. Slicks and wet don't mix, anyway, is this a total?

    Not a great day, I put the story in reddit: https://www.reddit.com/r/Supra/s/Kd4Y87vJSF Here are the pics: All the bags were deployed, cracked windshield and probably the frame is bent, but... what do you think? I'll know for sure but I would like to know what do you think. Seems to me is...
  2. 305/40/18? Is 27.6" too much diameter?

    Hello, I would like to know if someone has tested this diameter or knows if it would fit in the rear? Not the width but the diameter. I'm hitting 130mph at 6800 rpm or so, I would like to drop it to 6500 or closer. Wheel is 11" width and 18". Thanks
  3. Supra Manual - Comparative Performance Analysis

    Hi, I would like to create a pinned post with real world data about the Manual Supra compared to other manual cars in the same market segment or same power levels.

  4. Best valved titanium exhaust?

    Hi, I am looking for a not so loud exhaust. It must be made of titanium for the weight savings but I don't want a loud one. There are a couple of options out there, some are valved, some are single exit. But honestly, I am reaching 40 and the loud exhaust gets old very fast to me, like, every...
  5. Compression ratio for the B58 in the 2023+ Supra?

    Hello, Does anyone has the factual info about what is the compression? There seems to be conflicting information: First 2020 Supras had the 2 port exhaust and 11:1 compression ratio, but then for the 2021, the B58 was updated to the 6 port exhaust, but I remember that the compression was...

  7. A word of caution for meth injection sprayed through the throttle body...

    Not to scare people or trying to cause panic or judge people using this setup. Just sharing some information, that may be useful. This fellow blown his B58, the culprit seems to be running lean in some cylinders while spraying meth: This is the main reason I would go port injection instead...
  8. Opening front plastic cover? [Solved][Dumb question, radar is there]

    Hi, If you take a look at the grill and the intake design, looks like the plastic cover is exactly in place to cover air: Not sure why Toyota put this cover in place, maybe for safety and avoid having debris and water out of the intake, or to protect the heat exchanger behind? Haven't seen...

  11. Basic questions on Meth Injection...

    Hi, I am thinking on going with Meth Injection, maybe this was covered before, but can't find it. I do have very basic questions: Where to get it? Like, it is true that the washer fluid is ok?, maybe adjusting the mix to 50\50 ? How long does it last? Like, the fuel tank is good for 250 miles...

  13. Share your IAT and Ambient Temp. (If you log it)

    Hi, I am doing some experiments with the Intake, I bought the MST CAI and it sounds great, however what I see is that there is an increse in the IAT. With the stock air box was about 85°F driving and 95°F at a stop on idle. Now with the CAI is about 95°F driving and up to 110°F on idle... at...
  14. [Update/Fix]Transmission acting up. No Drivetrain Malfunction msg.

    Hi, So all started today at the dragstrip, I did a burnout and then, at the time of the launch, I floored the gas and keep spinning all the way until fuel cutoff and I got the drivetrain malfunction message (only this time), so I drove slowly to the pit area, no CEL or anything. Shut the car...
  15. AMS Downpipe + MST CAI + BM3 E30 OTS = 124 mph trap and 11.6 1/4

    Hi, I went today to the Sac Raceway, great people running today. My best was 11.6 s with 123.9 mph, worst 11.7 124 mph. I really need tires and practice, this trap speed is for a high 10s run. The setup is just AMS Downpipe and the MST CAI, with the OTS Stage 2 E30 from BM3. I don't think...

  17. Phantom Matte Gray Owners, Manifest Yourself

    Hi all, I've been lurking the forum for a while, just tuned my MKV yesterday with the Bootmod3 OTS 91 Oct map and I am very happy with the results.
