ok heres the deal I just recived my 89 Tubo II and i had to take it for a spin it ran great and iddled well and everything. But when I got to about 5.5K or 6 thousand it would seem like a limiter would cut on and it would kind of jerk for a second and my revs would drop down a bit and then accelerate fine. And I thought that this was to low set to be a proper limit. Could it be that becasue its a J-spec car the limiter would be lower. Or do i have problems. I am very new to the Rotary but know something of pistion engines. Thanks

oh and by the way, i did search and its a brand new exaust system so i dont think it was my cats. But I was going to gut them anyway so I dont know. I just need some insite

You dont know if its a full exhaust so it could still have the old cats.

Fuel cut at 8.6psi. This is controlled by the ECU, and is nothing to do with the J-spec engine. You need a Fuel Cut Defender to avoid this. Search for "FCD" and you'll get tons of info.

Fuel cut, do you have a boost gague to see how much boost your getting, you might be getting to much causing the ecu to cut fuel to the rear rotor. A fuel cut defender could help you if your not going to much past stock boost.. Try searching for it.


Edit: Got beat to the punch

Mikol

It seemed i wasn't getting much boost at all. But I will take it for another burn tomorow and check it out. I hope it is, becasue if its a cloged cat i dotn want to buy all the parts to keep the boost from creeping

How much boost are you running? If you don't know, the first thing you should do is go buy a boost gauge.

And you don't need to buy parts to stop boost creep, you port the wastegate.

Hes got the factory boost gauge, what boost should the car be running stock?

Totally stock ~8psi.
