I got rodknock, now I'm really contemplating getting a jdm 7m from one of the many engine importers. Just wondering if anyone's had good luck going that route. Thanks, Eric

If the ecu's not the problem, you may not be getting enough fuel. Try bypassing the stock fuel dampener.

I had one on my 88 1jz, and I couldn't have been happier with it. The sound was amazing at WOT and at idle it purred like a kitten. It's not loud unless you "Get on it" And cruising you can't even hear or feel it in the cab. An awesome exhaust.

Hey, I live close to GR and I have a black 87 Turbo.

You should have no problem using a BCC, it's a great tool. Just make sure to use a wideband gauge to make sure you're not tuning it lean. With 440's though, you shouldn't have a problem. But the best way to avoid hitting fuel cut, is to get AFPR and up the pressure in the line, while using...

The white wire is the sensor wire

Cool. Someone else has the same problem as me. My car was doing the same thing, and I opened up the ecu and have a leaky cap aswell. Send your ecu to DM.

I talked to him on the phone about it, he thinks the capacitor leaked. Hopefully this is the problem with the car, seems like it's worth a shot to send it to him for repair before doing hours of diagnostic work, or having it towed to a shop that knows nothing about 1j or 2j. I try to turn my own...

My car has been running wierd for a while. Sometimes it will run great. Sometimes I'll feel a sudden loss of power. But I went to start it today, and it fires up, but immediately dies. I checked fuel, so I decided to open up the ecu. This is what I found. Is this what a blown circut or "cap"...

How much does a new O2 sensor cost? I heard somewhere crazy like 400+???

I believe my car is running in limp mode. Could the O2 sensor be doing all this? And what is a code 47? Anyone ever get this code?

I have a problem. My jza70 is throwing error codes. I get codes 21 = O2 sensor 31 = MAF????? 47 = ???? Now, I went to cygnusx1, and the code 47 does not exist for the 7m. 31 is a MAF. And since it's a 1j, there is no MAF. So I need help figuring these codes out. What do I need to fix? My...

^ I am running a 1jz with safc and fcd, my boost is set at 17psi. Stock injectors and turbo's. I'm still in the 13's a/f r. Why is everyone running lean?

driftmotion. Very good condition. Runs great. No issues whatsoever.

Where can I get a map ecu harness for the 1jz? I've been looking, but can only find ones for the 2jz.

^ You are correct, it is attached to the firewall just to the left of the brake booster.

I finally finished my 1jz swap and it's been running in my car for about 2 1/2 months now, and I'm happy to say that it was worth it. The only problem I have with the motor is the low end torque. Obveously the 2jz is the better mtor to swap into your car, but penny for penny you're better to...

Elaborate please.

I just read this entire thread. And all I have to say is "What the hell?" Go to SF and look at the 1/4 mile time for 1jz's with stock twins. Some are in the 12's in a full weighted car. I'm getting a WB tomorrow and going to Martin dragway next friday for test and tune. I'll come back here and...

^ Is it even possible to swap out the twins with the engine in the car? The piping on the rear turbo hits the firewall :(
