I believe you only need to have 1 working cat in place in CA. Tho the 2nd one would prolly help your chances so long as its good and up to temp.

Yes they come on when the engine is too hot or anytime the a/c is on. And ya i meant cant. Can always either refil the clutch fan with new fluid or get a new or good used one. The 1hp gain you get from removing it is lost in amp draws on the alternator.

There good systems and there newer and better updated than the old hks stuff. Esp the maft pro because then you having timing control.

Welcome. Looks like the shocks are on backwards.

You can find used maft pro's for 500 and then havfuel control, timing control, boost control, and wideband. Or you can get the standard maft for 400 new and run speed density. Or you can get the maft gen II and run the gm blow through sensor and just mount the sensor somewhere in the ic piping.

Why not just get a lsd. You can get them fro the junkyards on 50% off day for 90$.

Thats not that bad. I wonder if there is a way to trim them down a tad.

They should work fine. If they are too tall they will just be about as tall as the top of the valve cover. Just need to make a mounting bracket for them.

Time for a twin disk.

Im sure you could. Idk what plugs changed on the body harness tho. Putting a 89 harness into a 87 is not that bad tho.

Damn that revved fast.

Gray plug hac sensors are built into the ecu.

It also helps in keeping the heat in the exhaust.

http://www.cygnusx1.net/Supra/TechTips/engine_error_codes.aspx Codes will be different tho i think. Have to google for the codes idk where the link is for the 1jz. Tho they might be similar on some.

Could also be the valve lash out of spec. Squeaking noises under boost? Squealing>? Whining? Could be a belt or could be the turbo going out.

Check the codes by jumping te1 and e1 and counting the check engine light flashes. Also verify spark. verify fuel. verify the ecu is good.

You need ecu grounds. There are 2 grounds on the intake manifold for the ecu. Grounding the block to the chassis and head is not going to do that. They go from the ecu through the harness to the manifold.

Yes it is. Or else its going to take forever for the oil to warm up. Stock goes off pressure so no oil even goes into the oil cooler until you reach the pop off pressure for it to go to the cooler. And then it just goes to the pan after. With no stat your basically having a hot engine with...

Ya open it up and look for leaking capacitors. havnt heard good things about the guys business so idk about his wiring. But are you not using the stock grounds that are on the intake manifold?

Whats up with the red wires? What did you use to do the wiring? Is the ecu good?
