head swap
I have a 89 CRX DX and need just a little bit more HP. I dont care for huge power with this car, I have a Subaru for that. Can I replace the head with one from a SI?

The best swap for that, rather than a head, would be a MPFI swap... Swap out your DPFI (2 injectors) for MPFI (4 injectors) from an Si... Lots of wiring tho, but would be worth it, and give u that extra boost you are looking for...

Ok, if the heads are the same what about cams for the 1.5? I don't really want to mess with wiring, and I don't trust anyone with a "custom" job. I was hoping it be something I could swap in a day maybe a few hours (with the parts).

I actually know what you mean.
