I have a few things I was curious about concerning Limp Mode, specifically in my 1JZ ECU. Just a quick background, I have a 1JZ swap in an '89, Holset HE351, basic supporting mods, and a MAP-ECU2 to tune with. I have the car running without the O2 sensor plugged in. I do have codes 21 & 25 which...

So I just completed my 1JZ swap. The car is running great but I have a quick question. I relocated my battery to the trunk. I have a distribution block near where the battery used to be. The shell I bought has one of the 2 white wires coming from the + post cut off. What does it do? Where does...

This one's pretty simple. I just bought a 50MM Ebay Wastegate (SSAC) and I'm about to finish up my 1JZ / Holset swap. The turbo has 3 ports on it. A big one and a small one on the top, and a big one on the side. The screw in elbow will fit either of the 2 large ones. I'm going to be running the...

I'm a week or two away from having my 1JZ swap running and I'm beginning to think I don't have my fuel routed correctly. It's a JZA70 1JZ and a late '89 Turbo chassis. The chassis has the 2 fuel lines coming from the tank. One has a barb on it and accepts rubber fuel line. The other is the...

I have a quick question about my 1JZ and the stock O2 sensor. I have a '89 Turbo with a JZA70 1JZ swap about to be completed. I'm going single from the get-go and using a MAP-ECU2 for tuning. On the MAP-ECU forum most users say to leave the O2 sensor unplugged so that the stock ecu won't...

I'm in the final stages of wiring up my 1JZ swap. I'm going to be using a Holset HE351CW turbo and Map-Ecu2 for my engine management. I only plan on controlling fuel initially but eventually plan on doing timing as well. I attatched the file to wire the Map-Ecu2 into the 1JZ harness and I'm...

I'm curious if it's ok to dunk injectors in a parts cleaner without harming them. I know that they need to be sent to RC or Witchunter to be cleaned and flowtested correctly but these are just some JDM 440's I'm putting in my 1JZ to get the car running. I won't be turning boost up past 8psi...

I just got a present in the mail today. It was a 1JZ SPEC Flywheel. I haven't seen anything about it on here so maybe it's a new find. The store is LMP Performance or LMP Racing. There are 2 websites and they appear to be the same company. The flywheel is steel. I'm not sure of the weight but it...

I started tearing apart my 1JZ today in preperation for replacing all of the seals and gaskets. I also plan on going single. I noticed there's a coolant line that goes from the back of the WP housing all the way around the back and to the intake side. I assume this line fed the turbo's and it...

I've searched around and suprisingly can't find anything about these on here. I noticed them on EBay a few weeks ago. They're throttle bodies from XO2 that claim to be direct fit for 1JZ, 2JZ, and 7M. They also claim to use the stock TPS and vacuum lines. They have them in 65mm, 70mm, 80mm, and...

I should have called it ECU and not CPU in the title. Figured I'd throw that in there before someone corrects me... So I began tearing apart my '87 Turbo today and ran across a curious part. They guy I bought the car from had already done a lot of mods and when I took the CPU out the top of...

I've always assumed that jaxed.com was a known thing around here but I searched and it doesn't seem like it. Anyways, jaxed.com is a site that compiles all of the listings from craigslist, ebay, cars.com, and a few other sites. It does this with mostly rare or hard to find cars and the Supra...

Ok here's the background to the question. I currently drive a '87 Hardtop Turbo but I'm restoring a '90 Targa NA. I'm going to be doing a 1JZ swap into the '90 NA and parting out my '87 Turbo. The question is what should I consider swapping from the Turbo to the NA as far as Suspension parts go...

I've searched everywhere and can't find any information on these fenders. It seems too good to be true so I'm assuming they are. MimoUSA has a listing for Z3 style fiberglass front fenders but they are listed for 2 Supra's, either 80-93 or 93-97. I don't think MK2 and MK3 fenders are the same...

Just a quick question. I searched everywhere and looked in the TSRM but couldn't find what I was looking for. How do the vacuum lines for the EGR Modulator hook up? Right now I have the "Q" side going to the line under the intake and the "P" side going to the EGR itself. Is this right? I do have...

I just finished putting my car back together after doing a headgasket and everything's working smoothly but the throttle body is sucking air. I used the gasket that came with my gasket set but it's still sucking air. I have no toyota dealers anywhere near and I have to get it on the road...

OK, I was finishing up my first headgasket job last night and the oil dipstick wouldn't line up with the mounting hole on the turbo (it was lower and when I tried to raise it to meet up, it would "pop" out of the hole). So I just zip tied it to the wheel well. After I finished and started her...

So I'm in the middle of my first headgasket replacement and I was wondering what else should I do to the head while I've got it out and torn apart. I'm using ARP studs and a Fel-Pro gasket to put it back together and I don't plan on exceding 14psi. I'm going with a Fel-Pro because I don't want...

I was wondering if anyone was familiar with these injectors?? I'm pretty much a noob with Supras (only owned one for a couple of months) and I'm in the middle of doing my first headgasket (what was I thinking???) and the p.o. told me the car had the notorious Venom injectors but when I got...
