I recently did a stock jdm gsr swap into my civic ek. Im also using the stock p72 obd2 ecu. Anyways after the swap I drove it around and it feels like a single cam vtec or a d16y8. It only feels strong when I hit vtec but for daily driving it hesitates for a while. Am I loosing fuel pressure or something? Somedays it feels really torqy where I barely have to step on the gas and other days its very sluggish. I have no cel lights but my spark plugs are kinda white indicating that Im running lean. Btw Im using the stock civic fuel line. Maybe thats why its running like a single cam?
tribalpaintball do you know anything about a gsr? I am running the stock ecu which is a p72. what are you talking about?
w/ your engine swap you should at least get some sort of a/f tuning device. apexi has a real good one. buy one, get it tuned at your local shop w/ dyno, and you should be pushin at least 160 to 170hp.
