So I have a ‘93 EJ2 DX Coupe that had a D15B7.
I swapped it out with a JDM D15B that has a p08-5 VTEC head on it. I have a few questions here:

I have a virgin p28 but with it installed it won’t rev past 5.5k. What should I do there?

My dizzy is going bad, I have a misfire upon startup, I hold at about 2.5k rpms then it goes away, what kind of dizzy do I need?

When i’m at 4k rpm+ I get a white smoke out the exhaust, head gasket?

Was the the original head that came on the block? Cause the wiring harness that came with the D15B doesn’t have a wire for the vtec solenoid
