My head gasket might be ok, (key word MIGHT) I bought the car from a 50 year old guy 1st owner, he was not a car nut. Anyways, I did the retorque last summer. Drove the car all summer with now issues running at 8-9 psi. And I didn't baby the car around. Mods 3 in exhaust (DIY pipe...

Ok, I have done a retorque up to 70ft/lb, when I retorqued I found like many other supra owners that the back bolts were at 10ft/lbs, In otherwords they are stretching, and failing. I have read other forums where guys have taken out bolts one by one and replaced them with ARP Bolts...

As my dad says " don't fix it, if it aint broke" I don't feel like replacing my stock head gasket but I would like to make sure it stays in place. Everyone says put in head studs instead of bolts because they torque more evenly. I was wondering can I replace the stock bolts with ARP...

I own 2 cars, an 89 Supra and an 88 Alltrac, now reading on the alltrac forums I have found that there is a Fuel Cut mod that you can do to help with boost cut. I know there is a lot of similar design on these cars so I was wondering if this same mod could be used on a supra??? Whats sensor...

Yes I know my alternator is bad. I just tested it and I am only getting 12.5volts out of it. And I checked my brushes and they are done. All I want to know if there is suppose to be grooves that the brushes run in on the shaft? It says in the TSRM that you only need approx. 1.5mm of...

My Brake, Battery and Burnt out back lights, are all on at the same time, This happend all at once as I was driving home from work. I did some research on it and found that other guys had this problem when their alternator was going. I checked my alternator and it wasn't making any charge. I...

Nope she bolts right up to the downpipe, as for the loudness, I guess I was a bit wrong about that. It doesn't sound very loud inside the car, When you hit boost I can hardly even hear my exhaust (from inside the car) But I was driving beside one of the guys I live with and he has a Ford...

Just built my own 3 in exhaust and love it. Check http://www.supramania.com/forums/showthread.php?t=17342

As for the 1/4 inch flange, ya it was what I had around the shop. I don't have a Video Camra but maybe I can borrow someones and get something up here for you guys. Thanks guys for the positive feedback. I am all about the DIY thats the best part about building my car. I think that I...

DIY Exhaust Supra I know there are a lot of hardcore Supra owners out there and they are probably going to bash this because it’s a barnyard job, but I was happy with the power gains so I figured I would post it. What you will need: - 1/4 inch plate to make exhaust flange -...

Saskatoon SK 1989 Supra Turbo

I just cleaned my cold start Injector today. I had the same problem with taking it out it comes out quite hard. If you take and pull it towards youself and play with the wires in back to loosen them up a bit it will come out reluctantly. (take gas line off) Just a toothbrush and some gas...

Ya I have the same problem with my heater, Its -15 and I can't defrost the front window

I am pretty sure it is not my battery because it cranks over fine. Cold start injector, is there any way to test it? I am not familiar with them I just got the car. I guess I have some research to do.

Changing the subject slightly I seem to have a problem starting my car. When it is cold I have to let it turn over for a while before it starts. It starts every time though, but it just cranks over for a long time. The car Idles fine no codes it just seems to start hard. I am going to try the...

Thanks Guys thats what I needed to know on that, one more question Since I am on a school budget I will hold off on pumping up the boost, but as a precautionary measure I would like to retorque the head. I have the tools... know not to torque more then like 10-20 lbs at a time. My Question...

If you don't mess up your head when taking the old gasket out shouldn't it be fine? Can you explain why you need to with a metal head gasket and not a composite one?

I just picked up a 89 supra and am wanting to do some precautionary measures before I start making HP. I have been told by a few guys in my engineering class that I don't need to machine (Ground/Lapped) my head when replacing the head gasket. (Note: My headgasket is not blown, and I am assuming...

I have just purchased myself a 89 supra turbo, I am having issues with it running rich. I am getting code 31 (((7M-GTE) Open or short circuit in air flow meter signal)) I am wondering if there is any way to test if my AFM is working properly? I have tested the ohms for the temp reading and it...
