Hi all, I keep getting a recurring code 12, "no ne of g signal to ECU within 2 seconds after engine has been cranked". Unfortunately, this is all Borg to me. "Trouble areas: cps, cps circuit, starter signal circuit, ECU". The car seems to run okay, but sometimes it takes up to 3 seconds for...

I want to do Tookwik's c.o.p. mod, and I was wondering who is running it now, and if anyone has an extended harness for sale. I have the other components, but I pretty much suck at wiring, so I need the extended piece with the coil plugs and engine harness plug. Or if someone has done this and...

I should know this, but is there any difference between n/a and turbo heads (apart from casting revisions and the intake cam)? Reason being, I'm rebuilding another 7M, and I have a good condition n/a head, I was wanting to use (with my turbo cams)...are the valves the same composition and size...

I want to do a coolant system flush, then I'm switching to Xerex g-05. Where's the best place to put a "t" to flush the whole coolant system out? I searched but missed it. I did find jdub's advice in another thread...so the Prestone would be the wtg? Did you use Prestone Heavy Duty Cleaner...

I have a rebuilt '90 7M. It failed aircare with very high NOx readings. It currently has a Lexus Afm, RC 550's, Denso MK IV fp, AFPR, and 3" exhaust. My wideband reads fairly lean at cruise and idle (high 17's) it drops into the high 11's under boost. My fuel press. is set at 30 with vacuum. The...

I have a chance to buy a pair of folding mirrors, can anyone explain what all I need to make these work on a LHD car? Is there a control box needed as well as the mirrors and switch? Is there alot of wiring involved? I'll try to search some more to see if this has been covered, thanks.

I was looking for rear brake rotors, and came across these, has anyone used these, are they any good? http://cgi.ebay.com/ebaymotors/1990-TOYOTA-SUPRA-MA70-MK-III-Drilled-Brake-Rotors-Rear_W0QQitemZ320097030986QQcmdZViewItem?hash=item320097030986&_trksid=p3756.m20.l1116

I remember awhile back folks talking about a stock looking boost gauge that goes up to 30 pounds. It fits in the stock location and looks the same.(with the exception of more range...). Anyone on here have that? I'd like to get one if so.

I"m putting my driveline (manual '88 7MGTE) into my '90 Auto car. Has anyone done this? From what I've read I don't need to change anything except the cps (for diff. plug), the throttle body, and the water neck. I'll of course use the '90 harness and ecu. Am I missing anything else? I realize...

Is anyone currently running these wheels? Any pics on the car if so? I'd like to buy some, but am unsure of max widths front and rear, and offset. I was thinking 17X9 front, and 17X10 rear, +35 mm offset. I don't want them to rub though. I'll be using Eibach blues and Tokicos. If anyone has the...

I'm currently rebuilding my '88T, and I have a used diff. to go in. It looks nasty, and I'd like to know the best way to restore the case's appearance. I was thinking of removing the back cover and sandblasting that, and wirewheeling the rest...anyone else gone through this?

Can anyone help me with an "idiots guide to AFPR installation"? I bought a used one but didn't get any install directions with it. It obviously isn't rocket science but I seem to be having problems. Apparently you can discard the FPD with this unit, but some install directions would be a great...

I was checking the oil and I put my hand on the ignitor, damn! Is it supposed to be this hot? Maybe not glowing, but I couldn't leave my hand on it, whats the deal? Is my wiring harness not grounded well or is this by any stretch of the imagination, normal? As a matter of fact the fuel pump...

I'm currently budget building my '88T and I bought Tokico shocks and Eibach springs for it. I'm wondering what else I should do to improve handling, ie balljoints, subframe bushings, better swaybars, different swaybar bushings, that sort of thing. I've tried to read the pertinent stuff, but any...

I'm currently building an '88T, and I'd like to relocate the battery to the spare tire bay. Can anyone offer any insight on this? I'm not sure the best place to run the cable (from back to front). ie. Interior or Exterior. Thanks!

I was hoping someone could lmk if the "generic" clips from HPF for the wiring harness are the wtg or if there are ways to change the inj. themselves to accept the stock harness clips? I bought some 550's for my build awhile ago, but didn't get clips. The inj. I have don't fit the stock harness...

My '88T project is slowly coming together, but my harness was in rough shape due to an out of car garage fire. I found a decent '88T auto harness but the car is manual. Are there any important issues to consider by using this harness? ty for your thoughts on this. Merry Christmas folks!

does anyone have a pic of an '88T tps? I can't find mine after teardown, and I don't think the brown backed one I did find is from the '88... (note to self, organize parts better after garage fire)

I am in the processof upgrading my '88T and I'm wanting a FFIM. What connectors/sensors will be needed to hook up to it if I'm running Maftpro with s/d? Buddy is building me one, so I just want to make sure I've got all the required fitting sites drilled/tapped.

I've looked thru the offerings @ HPF etc, but I'm just wondering what people are using on here...Any kit recommendations? Or is it easier to buy universal parts and diy? tks for any input.
