Code 42 comes from the speedometer speed sensor I'm pretty sure. My supra was a swapped N/A (no ABS) to 7M-GTE, no codes. AFAIK, AC shouldn't throw a code unless you hit the button.

The seat is a Kirkey Intermediate, Road Race, 20 degree lay back. Nice seat, even though it's bolted to the floor! I picked mine up locally, but I see them at Jegs online too, for a fair price. I paid extra for the Air-Knit fabric, with the denser foam. I want some comfort... Van
I like it looks great with the cloth do you know what the width is on the bottom? looks like it might be around 20 inches the bigger size.
I have the 17 inch hip width seat w/ Air Knit cloth. Additionally, I ordered the Kirkey seat mounting brackets and back brace. Total cost: $502. I also purchased a five point DOT/SFI approved racing harness for $280. Getting the seat professionally installed cost me an additional $260. It starts to really add-up quickly!kakanator;1849473 said:
The seat I ordered tends to run a little big, so follow the directions closely when ordering yours, so you get the fit you expect. I experience shifting around in the seat on tight, fast corners, which is fatiguing during a race, as I'm not tightly fitted into the seat. Consequently, I must use my stomach and back muscles to keep my upper torso from moving as it does (too much). That movement also affects my ability to steer accurately, as I have to use the steering wheel as a support for my upper torso. The pressure on the arms limits them for use in steering the car. Even though the seat is made of aluminum, we can only bend the upper portions of the seat so far. The next one I get will be a 16 inch width seat! Van

So, the JDM ECU isn't getting a signal from the USDM speedo? What consequence does that have on the engine?
I removed all the AC components from the Supra... That's the cause for the AC code.
Thanks. Van
The Supra blew out a clutch last week; it was regularly thrashed at the track and DD since 2007. It's in now for a replacement from Driftmotion: Action Stage 2 clutch kit, which includes a 2800 lbs pressure plate, stock clutch disc, throwout and pilot bearings. I also am having a new Fidanza friction plate for the 11lbs flywheel installed, the stock Toyota clutch fork and mount, and hub, as well as a leaky output shaft seal on the r145 transmission replaced.
The flywheel and clutch assembly will get spin balancing before going back into the Supra.

Oh ya! It'll allow me to brake later in the corner too. Reducing rotating mass there will improve the moment of inertia, like you said catching those revs quicker, especially out of the turn. Ideally, a smaller diameter clutch disc, PP and flywheel, would drop a lot of rotating mass, but at this time I don't have about $2k to apply to that combo. Exedy makes a great clutch kit I'd prefer to have installed. A 7.8 inch clutch w/ twin plates that has good drivability and reliability. Van

The no ac wont cause a code unless you try to turn the ac on. Code 51 is also shared with no park / neutral signal (for autos) and no idl signal from the tps.
And I had a jdm ecu when I was n/a, went to a usdm ecu when I swapped to Turbo. Didn't change the speedometer. No codes. I'd check the circuit between the speed sensor and the ecu. I'm not sure what the ecu uses this sensor for. I'm sure somebody else would be able to answer.

The Supra's getting the pressure plate CNC'd today. Plan is to install it on Monday. I'll see how much difference taking off 1.5 Lbs on the aluminum flywheel improves shifting...
The next thing is to go out and get some track time! Van

Yes, the goal is to reduce the rotating mass where it has the most effect, near the ring gear. The scalop was done in a CNC machine around the inside edge, being careful not to lose the balance. I'll have the total weight loss figures on Tuesday, when I p/u the Supra at the shop.
There was a small oil leak coming from the rear aluminum spacer plate I made to fill the gap between the crank scraper and the rear crank seal housing. The mechanic removed the rear spacer, cleaned the surfaces and replaced the spacer, sealing it with J.B. Weld. We'll see if that doesn't eliminate the seeping oil. Otherwise, the rear crank oil seal was dry, as was the transmission input shaft seal.
The transmission was leaking out the output shaft seal; The new rear transmission seal that I got from a local Toyota Dealer, was leaking, and it was replaced along with the clutch, with another "new" seal from Driftmotion.
Anybody ever have that happen; install a new seal, and it leaks?

yeah, ive seen brand new seals still in the bag be put in.. and see it the next day, looks like its in right, but it wasnt and leaked.. so it dose happen..
Okay, $2,100.00 later I can hardly tell the difference shifting the car on the street; off I go to the track! I know that it is only 1.7 Lbs lighter than what I had in there before, so I may not realize a noticable difference in performance on the street.
I'm very pleased with the way it downshifts into first gear, better than before (with the seven year old Action stage two clutch kit). The new clutch is an Action stage two clutch kit from Driftmotion, plus all new Toyota clutch fork, hub, washers and fork spring. Van

you know after saying that, i wounder wheres the point after you take so much off, that it has basically no gain to the power band or holding power? hmmm..
I don't know what has happened to my Supra, :dunno: but it definitely has more power, since getting the new clutch kit and the flywheel lightened. I also had the mechanic install the energy suspension brand transmission mount. The car is breaking traction in second, by just stepping on the foot feed; something it never did before! When over four thousand RPMs, pushing the foot feed to the floor, causes it to loose traction in third too. Time for wider wheels!
What has improved the torque and power to the wheels?

sounds like you need to barrow my 275s and see what you think.. so it seem like it has ALOT more power now then before?
Yes, it has never been able to break the tires by simply flooring the gas! What I need to do is get the Supra down to VIP Performance for a Dyno test.bloodasp90;1869137 said:
I suppose the seven year old clutch, flywheel and pressure plate friction surfaces, may have contributed to loss of torque to the wheels... That all the drivetrain components are new plus the harder transmission mount, may have been all the Supra needed to make it not very streetable. I had to turn down the boost yesterday. Van

I'm impressed that you dd a car you track. Mine feels (well, felt) harsh on the road and like a wet noodle on the track.
What does it tip the scales at (sorry if it is posted and I didn't read).
