I have a 92 sc, with a recently added turbo kit. Now I'm having some issues. Car revs up fine until 5 grand and then will just sit there and not go past it. Anyone ever have a problem like this? My downpipe didn't have the right 02 bungs so both are disconnected at the moment. Could this be my issue? Or any other ideas. Everything else is stock besides the turbo kit. Wasn't doing this before the install.

Needs more boost, all of it actually. jk

I would say get everything plugged in like it should be first. No need to go chasing rabbits when the car isn't put together yet.

It's definitely not the O2 sensors. Still stock ECU? Is your coil wire shorting on your turbo intake? Did you use the 4runner distributor cap? What are you using for tuning?

Check to see if your MAF sensor is connected or positioned correctly.

check you neutral safety switch. If the loop for that switch is close which means engaged the car will not rev above 5k start there. This is the reason for guys going from auto to manual have to engage the neutral park switch to start the car but have to disengage the switch to let the engine rev past 5k I hope this help
