What other than an ecu chip can be done to a b18a motor that is in a 91 acura integra to boost performance.
It is ran in a 4cyl strictly stock class on a 3/8 mile dirt track. But any suggestions on some hidden tricks would be awesome. Not much of a mechanic so easier is better!
Also would running it in 2nd around the whole track damage the engine??

Thank you!!!!!  

I wouldn't run second. 3rd is your best bet but give it a try as long as you are not keeping the revs up really high. I went with a header and intake on my 1990 Integra.
