Hey guys, I'm new to this an I just bought 91-92 Nissan Bluebird SSS has atessa Awd, sr20det. Problem is that when it warms up to operating temperature it goes into limp mode? And won't go above 1500-1600 rpm then drops. I have already done a new Maf, Thermostat, Heater Core and Distributor, Fuel and Plugs. But it still does it. Originally thought it was blockage in the coolant system. But now thinking it could be a clogged cat? Any ideas? Before I drop anymore money into it haha. Thanks.

Sounds like it could possibly be intercooler piping.

Have you checked for boost leaks?

Yes. I have it all seems fine. I don't have much intercooler piping since this is awd it has a top mount

I had a problem at a track day where the car would not rev passed 1000rpm.
The wiring to the maf was loose and not connecting properly.

I'm going to have to double check everything I have already checked, fixed and replaced. Thanks so far guys.
