Be glad you're not in California. We have one of the toughest vehicle codes in the country. No mods are allowed unless its been approved by the state, or is OEM on the same year or newer. We have dyno type smog inspections every two years. They're even talking about smog inspections on...

I've heard Porterfields are good. I've got a couple of sets in my garage for my cars, but I haven't installed them yet. I'm very easy on brakes, so I don't have to replace them for 100k mi. or more. I got the Porterfields for my wife's car. She uses brakes annually. The ceramic I hear don't...

300 HP at the crank is no problem boosting up to fuel cutoff using basic mods. The stock turbo will make it. Once you go to the Lexas mod, you'll of course have to "tune" it.

Pull the 15A EFI fuse and check to see that it has power on one of the terminals. Use chasis or battery (-) as ground. If you don't and you have an open circuit down stream, you won't show power even if there is power. No need checking things that aren't connected to the same circuit or...

The basics wire diagram and format is the same. But there are some differences in certain places. I don't have a scanner so I can't scan it for you. I forgot to mention that the circuit also supplies power to the ABS computer and condensor fan. (Sorry I missed that.) And you problem could...

UPS isn't really good either. I had sent my home stereo amp back for warrenty work to the mfg about 40 mi. away. When the mfg got it, they called me, one of the solid aluminimum handles was gouged. They repaired it and sent it back. When it was returned, it was damaged again. So the mfg...

$15!!!!!!!!!!!! I paid over $100 back in '87 when I got mine with my car.

I'm looking at my '87 TSRM. Power circuit A runs off the 80A fuseable link ALT from the battery. It powers: Alternator Rear Window Defogger Stop Lights Tail Lights Fog Lights Dome Lights You do have the dome light turned off? I've left mine on before, but it takes a couple of days to...

The Black-Red wire coming out from under the EFI relay won't have power unless the EFI relay is energized. That means that either the EFI relay isn't energizing, isn't working when energized, or isn't getting power at the switch part of the relay. The relay might be clicking because the...

Toyota told me that the TSRM is not the way they set it. They short the service connector to get into basic timing mode (I forget which terminals...T1 and something?) and turn the TPS until the timing jumps down from advanced to basic. Then lock down the two screws. So thats how I set mine...

So if I want 500whp minimum on pump fuel, with a Spearco intercooler kit and what ever supporting mods needed, including an AEM EMS, what turbo would you recommend? And I'd like a ball bearing turbo for faster spool up.

The fuse boxes won't have a short in it. It just has the wires going in to the fuse and relay terminals. The box just holds these terminals for the fuses and relays. There's no ground wires and its made of plastic. The ground wires would be on the other side of the electrical component that...

So where's this going? I'm looking for a turbo that's good for 500whp. But I know nothing about turbos.

Do you have an huge aftermarket stereo amp? They draw a lot of current even at idle. And that circuit thats suppose to turn them off when the head unit is off never seems to work.

Any news?

I've heard that if the PCV system isn't working, you can develop pressure inside and oil will blow out from under the cam covers. Valve cover leaks are a common problem. But I think most of the problems is with the screws that hold the cover on. They should not be too tight because it'll...

If it were me, I'd go with GTE everything. Almost if not all of the high HP mods are only for GTE. The Lexas mod is good, but you have to tune it for your injectors. And you have to use it with the GTE ECU. If you go with the Lexas, you should go with the 550 cc, otherwise you're wasting...

Did you do any of the things on my post? I linked the wire diagram. But if you can't read it, do some of the simple things I suggested and I should be able to narrow down point your problem. If you have a volt meter, then you should be able to pin point the problem yourself. If you need...
