I have a 1997 Integra GSR. I bought a B18C Type R. I had the engine rebuilt with the following. Ported and Polished Head, Re-sleeved with 84mm Flat Top Arias Pistons, new race bearings, all new engine seals, Sachs clutch, Fidanzza light weight flywheel, AEM Cold Air Induction, JDM P73 Type R ECU ( Stock ), new old pump, all new belts, etc...

I have a couple questions:

One, when I start my car it sometimes lets a big puff of smoke go, somebody told me it might be a valve seal that is has unseated, but it will adjust after time. Is that true?

Two, it is very jumpy at low RPM’s and very slow, once I hit VTEC it pulls like hell. how could I fix this problem? I was thinking a Hondata S200, or S300. Will those fit on this ECU, or what ECU would be the best to get for power? And I don’t have the money for an AEM. I just want it to have power all around and not just at 6000 rpm's. I think the S300 is my best option so I can have Multiple Programs. But I need some input.

Also I live in CT will my JDM P73 pass all emissions tests, or will I need a USDM ECU?

I just want the best performance I can get for what I have into it. I built the car for all motor I don’t want a turbo or Supercharger. I don’t want it to be jumpy anymore and I want some all around power and torque.

Please give me some Knowledgeable Feedback.

 

Uh, a motor that built I would not be running on the factory ecu let alone be getting on it.

How many miles are on it?
Who built it?
Do they warranty their work?

Why all the built stuff and then stock cams?

S200 if buying used, S300 if buying new(since they don't make S200 anymore)

 

The ECU I have will that work with the S300? If I get the S300 will it pass emisions test? Lastly is my ECU the cause of burning a 1/2 quart of oil a week, I was told it was because its a brand new engine (1000 miles) and everything needs to sit in.

Thanks
