Ok so Im putting a c20ne into my 1.8 cavalier soon, and Im just wondering what can be done to them on a budget to get a few more ponies.
I searched google etc and most people seem to say dont bother unless youre going to turbo it, but Im pretty sure theres been absolutely loads of these tuned up over the years.
It already has a 4 branch manifold, and Ive heard the 20seh cam is a good upgrade? I know its never gonna be rapid, but if possible Id like to make it a bit more lively.
Also.....what are the differences between my 1.8 single point injection cylinder head and the NE head?
Thanks guys.
