The official ask zrk anything thread

[zrk]

Ever seen this @zrk? Not pulling any new codes with it which is weird. Came on after an alignment. Going in the shop today to see if he can make anything out of it or turn it off.

Someone suggested this on another thread. So I’ll show it to my mechanic. Thanks for your expertise and any suggestions you’ve got

Damaged ride-height sensor. Common/likely after alignment.

Will check that Sir! Wish I could send you a phantom grey Supra sticker or sumthin….. at shop now ??

Edit: The sensor looked good, was plugging in. We unplugged it and plugged it back in. Reset tire pressure (read that somewhere). No fix yet. Headed back over to the alignment shop to check it out.

Otherwise, the car is not going into limp mode from what I can tell. Just no nannie helpers and lots of on screen alerts letting me know. The new alignment feels amazing! So I still want to try it on the track this weekend.

Anything else you can think of?

kind of a dumb question, but ama ask it any ways since I'm learning more about my car each day. Why doesn't the supra have that stu stu stu sound, is it from the turbo it self or the waste gate. How do I get that flutter. Lmao

It does from the wastegate, but it's muffled pretty good with the factory airbox. You can replace that to get more turbo sounds.

The B58 also doesn't use a BOV. You can add one, but it's literally pointless unless you're running a big turbo.

Hey zack, coming to hit you with a few more questions

Sooooooo I saw this ad for a used jb4 for the b58, dude had it for about a year, but its not for the supra he was using it on a 740i. Just wondering is it the same fitment as the supras? P.S when going to get it what should I be looking out for, or asking about

Also, do O2 spacers work on Catless downpipes? I got a 22, but if I can get a spacer that works I would want to go catless, if not could u recommend catted downpipes that dont blow a hole into my wallet lol

Not a question. I really want to redo this flowchart for clarity. But I'll let it go.

What is your goal for your car in terms of time in the 1/4 mile? If you hit that goal, will you be happy, or will you still want to be faster?

Firmly into the 8s this (2023) year. 7s next (2024) year.

I can do that. How do you want it clarified? It's pretty accurate.

JB4 - Harness is different, but the internals are the same. Wire lengths will be different. If you're handy with a soldering iron, it'll be fine.

O2 Spacers.. hit or miss from what I'm told. You're not going to get much more performance out of catted vs non-catted w/ JB4. I used the MAPerformance Downpipe when I had a cat, it was relatively affordable, no CEL.

I wasn't questioning the content, I'm just anal about crossing lines in a flow chart.

Oh, no. I'm not going to do that.
