A huge improvement over the stock CA20S single cam 8-valve carburetted w/automatic trnasmission. Previously, I was at best 87ish crank HP, and now I am at stock 205 crank HP with the SR20DET swap. This is a full OEM swap with the exception of the intercooler and piping and recirculating valve. I am not looking at adding power. Just something that is reliable and will get me from point A to B in a respectable fashion. This was completed back in June.
