So I want to swap my engine out with one that has a bit more power... I currently have a 1989 Acura Integra 4-1590 1.6L DOHC (D16A1). What engines could I fit that would give me more HP? Do I have to stick with Honda motors? Super Charged, Vtec, anything that would fit and function correct would help. I think I can fit a 1.8L if that helps... I have a 1990 Honda CRX.

Thanks!!
