I just put a b20v in my integra92. I'm running the stock ecu with a b16 head. It has a ls trans 70mm throttle body. And also using a ls dizzy. It runs fine but ounces it is driving and hits 2 grand it starts jumping and cutting out. Could it be the dizzy???

 

You're running a PR4 ECU with a vtec head?

That's the first problem.

Second problem is the wrong distributor.

 

Bouncing around, probably backfiring.

I checked the part #'s for the distributor between the ls and gsr, they are definitely different. But that could be because of the housing bolt hole are different. The internals should be the same.
