My thoughts: Your '91 auto already has the wiring harness, and the ECU that works well with the automatic transmission. I would therefore keep the '91 wiring harness and ECU, use the sensors from the '89 engine that clip up, and change over only those that are different. I expect that...

Good t'hear that it's working for you.

1. Check to see if you grounded out something. I do this my checking continuity from the terminal to ground. The +b terminal should NEVER read continutity to ground. 2. Re-check your gauges. Coincidences are rare, and if you changed something in the electrical, that's more likely the...

So this may not be suitable for the OP then, since he seems to want loud. I don't MIND loud, but I'd really rather have silence. If I'm lining up against someone, the only clue that I want to give them that my car isn't just some NA poser is when they are watching my taillights recede in the...

Actually the stock headgasket isn't really the problem. Never was. The stock torque spec definitely is a problem, but the gasket itself wasn't bad. Granted, a MLS gasket is better, but when I had my engine out for a tear-down, I couldn't strip it to a bare block to get the block machined...

My ABS system has never caused me a problem, and has, in fact done things that are frankly impossible without it. Coming around a curve on the highway, and there's a jacknifed semi on the road. Hit the brakes. The right hand wheels are on sand, and the left hand wheels on good asphalt...

You won't know for sure until you clay it, but I would expect contact.

So by those numbers, the boost controller and SAFC are almost as much as the MAFT-Pro with all the toys... Hmmm... Kind of makes it a no-brainer if you want both of those functions. This is starting to sound like a better and better thing to me. I presume that it can be tuned for larger...

Okay, so you've got 0.050 milled off (1.27mm) and are compensating for that with a 0.2mm increase in gasket thickness... That still takes more than 1mm from your clearance. Add in increased cam lift and I can about guarantee that you are now running an interference engine. Take good care of...

I thought that it COULDN'T be my valve cover gaskets... But when I changed them, the problem went away... For a couple of years. The bolts that hold in the #3 cylinger head gasket (As Toyota calls it) are also possibly suspect, as was mentioned.

Anyone else running the HKS SSQV recirculated? This is what I will be doing, as soon as I get my IC piping finished.

Isn't stock bore 83mm? At least it is according to page EM-75 of the TSRM. In any case, I believe that the oversize gasket will work fine, but I would rather get the correct one myself. The 1-1.5mm lip around the cylinder bore may have some effects on the combustion chamber, and will...

The automatic climate control will not turn on the fan until the coolant in the heater core is above a certain temperature. Not sure what that temperature is, but when my VSV failed, the system wouldn't turn on the fan, let alone get heat out of the system. You can check if the VSV is...

Do you mean that the threads stayed in the block, or the whole threaded part? If it's just the threads, run a tap though it to remove the extra metal bits. If the shop doesn't take care of it, then those will be in the oil system, which is going to be a bad thing. If it's the whole...

Well, I feel sort of guilty for not having a cat. Sort of. Not enough so that I would pay to have one. In fact, not enough so that I would pay for a test pipe so that I could install one. I got the RT downpipe that eliminates both cats.

I don't know about all, but it's fairly common. Of course that's also usually in hot weather. :D I can't see how, but it fits the symptoms.

Timing belt? When my timing belt went, the engine would crank over all I wanted but it would never catch. The clue was that the tach stayed at a flat zero while it was cranking.

Could it be heat soak? Boiling of the fuel in the fuel rail. The resultant bubbles don't feed the injectors properly and the engine doesn't run until it gets a chance to bring up the fuel pressure. The problem isn't so bad once the engine cools, because the fuel recondenses, so all you...

Step 1, check codes. If the engine won't keep running, it's almost certain that it's going to throw codes. Check out The online TSRM FI-23.

Running on the lean side is a risk that I for one would not be willing to take. Besides, this still does not address fuel cut. Fuel cut is determined by the ECU based on air input. You can defeat fuel cut with an FCD, and hope that you don't run too lean, but that's not RAISING fuel cut...
