If there is no pulse 12 VDC to the subject connection to the ECU during the START, is it likely that the ECU will not recognize that the car is started and limit the engine to 4000 RPM?

Here’s the dilemma, I put on a Recaro steering wheel (JZ)and as a result had to delete the cruise switches on the steering wheel. I would like to keep the wheel on. Is there an alternate mounting place for the controls for cruise? I could take the switch apart I guess, and or wire some new...

Can't seem to get the fan to calm down, running at full blast. If I disconnect the fan ECU it slows down to "idle". I've checked the components as per below. Am I missing something? Pin # Dest 1 IGNITION (actually 7.5 AMP PWR, rewired to B1-16 + 12V) (checked OK) 2 SOLENOID +...

Took the car out for a 1st run tonight to see what it could do. Was quite peppy and starts, runs fine. Took it out on a highway to see the spool and torque at higher RPM.... The engine will not go over 4000 RPM. Just seems to die out like someone cut the electrical power or fuel. I...

I installed a stock boost gauge and a pressure switch and wired it per the TEWD (although not clear). I used a JZA70 cluster to figure out the connections for the drive circuit. I had to cut the printed circuit board so that I could make the connections (the cluster is from a N/A). I read...

So changed rear sub frame, all engine and tranny seals, new clutch, wiring harness. Now I can't seem to get it to mount in the engine bay. The rear turbo hits the firewall before the engine mounts line up. It was my understanding that the 1JZ went in with no mods... I don't see how it can...

JZA70 1JZ into '87 NA Looking for experienced feedback on which method is better. The extend or reroute. Option 1 : Extend main harness 18" and rewire JZ harness plugs to MA 70 Option 2: Drill 2.5 " hole in firewall below speedo cable (flat spot) reroute harness over AC and to...

I bought a 90 JZA 70 front clip to do a 1JZ swap into my ’87 NA. I have the option of keeping the ’87 bumper or putting on the 90 (I will be changing the rear tail lights). So I thought that it would be interesting to hear others opinions of which bumper set looks better.

I am doing a 1JZ swap into an '87 NA and was swapping out the rear subframe to take advantage of the stock JZA70 rear end I got with my clip. Things were going quite well until I noticed that the rear bushings were slightly different. So I just cut the rubber bolt / bushing centering molding...

Hi I'm doing a IJZ swap into a '87 MK3. I just read some posts on engine mounts and now i'm a bit confused. Sorry to be a pain in the keister.... My plan is to change the subframe from the JZA70 front clip into the MK3. One engine mount was broken when I pulled the engine out of the...

Hi, I was wondering of anyone has done valve seals on the subject engine, when it is in the engine compartment? If yes, which valve keeper removal tool and seal remover tools were used? Thank you.
