stays the same when on brakes. already pulled rear wheels and check calipers,and pads

I have a lot of vechicles with bad wheel bearings....doesn't seem to act the same..

87000 miles

hi guys iam having somewhat of an annoying issue. iam getting a bad vibration from the rear that almost feels like a broken belt in the tire or unblaenced wheel. ive had the car to the wheel and tire place twice to check tires,rebalence ,realign etc. noise is still there. the noise is not consistent come and goes. it seems to come back if I come after it. ive tried pushing in clutch and coasting while noise is there, still the same. iam assuming its drive line related. but really don't know where to go with it. any ideas?

hi guys iam currently in the process of removeing all the sequential stuff cause iam in permanant ttc and iam fabbing up dual intakes....anyways i have everything figured out except for this 3rd actuator that looks like a waste gate in the number 2 turbo....i was under the assumption that we only had 1 wastegate? it looks like this one opens up a flapper that connects the 1 and 2 turbos exhaust ports.kinda like a bypass? correct me if iam wrong but could this be somthing that gives number 2 turbo a little bit of exhaust flow before opening up the large flapper on the #2 turbo when in sequential mode. kinda like a prespool? anyways iam wondering if this should stay shut or be wired open when in ttc? on a side note if all this is true with only 1 wastegate wouldnt the #2 turbo just spin wide open and the #1 turbo regulate the boost.....? thanks in advance

// ok but i dont wana fool anything. i actually need it hooked up.......someone must know of a ignition wire that can be cut and routed through the clutch switch??

the switch under the clutch peddle that will let the car start only if clutch peddle is pressed in.iam pretty sure the uk version come factory with them but not the j spec. i purchased the factory switch from toyota and have it installed but dont know what wire i should cut and divert to the switch. there must be an ignition wire somwhere close......

hi i have to install a clutch switch for safty inspection here in canada. my j spec supra does not have one from factory so iam asking what would be good wire to splice the clutch switch into? thanks in advance!

main reason iam switching over is to reduce stress on the 2nd turbo...have read alot of horror stories of the 2nd turbo going to pieces due to the sudden smash it gets from the sequential operation

ttc stands for true twin conversion. its when both turbos spool together rather then 1 and the 2nd kicks in after(sequential) and yes iam factory tt

hi there i will be switching to ttc and wondering if the 12v fuel pump mod is needed? ive read it burns up fuel pumps...and after buying a walbro dont really wanna burn it up.but i dont wanna run lean either during the transition the fuel pump makes from 8v to 12v either. ps i do have a greddy fcd installed already if that matters thanks in advance for your comments!

Took it out looked fine. Cleaned anyways. Installed still the same any other ideas???

Ok I'll try that send let ya know

No mil light

Hi there guys iam wondering why my car is running so rich while cruising it bouncing around 10.5 while cruising at a steady speed. Is this normal I thought it was supposed to run around 14.7

ok thats all i wanted to know. in conclusion i will just step up to the med sized jet and leave the ratio at 25% meth. thanks everyone for the replies

25% meth is what i mean, as far as failsafes i have the boost safe wire from the aem meth kit hooked to the scramble boost wire of my aem tru boost so it will knock the boost back to stock if somthing happens

bump for info

very helpful guys thanks for the input. one more question tho where i only have 91 octane would it be benifical for me to up my meth mix to 50/50 to help with timing and such or should i leave it at 25%, iam running the smallest nozzle the aem kit comes with

isnt 12 getting kinda lean.

also do you guys think it would be more benifical to up the mix to 50/50 or leave at 25%

ok even tho 12 for a sec kinda scares me.....

yes on stock jspec turbos,ive heard ALOT different numbers bounced around for stock turbo limits, i have two settings on my aem truboost,18 psi and 15 psi, i run 15 psi on the street and only use the 18psi when my buddy with his turbo charged mustang gets a big chest.

hi there my current setup is bpu running around 17.5 psi, with a meth kit mixed at 25% with smallest nozzle installed that the kit comes with(aem)only can get 91 octane here ,ebc,fmic, anyways when iam giveing it, my a/f ratio hits 12.0 for a sec then drops down around 10.5 to 11, iam only running the stock jpsec 440 injectors with a walbro 255. can i up to the mix of my meth or go to the med sized nozzle to richin it up a little or are these numbers ok. any input is great, new to the supra community. thanks.

hi there iam currently running stock 440cc highimpedance injectors and iam want to switch to 550cc injectors, i would like to just get a 550cc high impedance injector to replace it rather then go through the hastle of switching to low impedance. any suggestions?
