I took my 88 integra to PIR (Portland International Raceway) this weekend. Pulled a 16.5 as my best time WITH a bad launch. Nobody was able to launch that night cause the cleaners weren't doing their jobs very well. My 16.5 was against a 89 square back that had headers, full exhaust system, high pressure injectors, and a difference ecu.. I dont remember what one. Keep in mind that the squarebacks are almost exactly the same as the 1st gen integras.. same chasis, almost the same weight, same weight distribution, basically the same engine, and the same rated hp and torque.
So you might not want to get rid of your integra just yet. I was BONE STOCK.. Literally nothing done and I barely beat him. But just in that race. The rest of the night he was pulling 16.2 continually.. But still
