I have a 1990 CRX HF with the D15B6 or 1.5l with a manuel Transmission and i am trying to get more out of this car. There is not a lot of selection around my area as far as parts.I am thinking on trying to chip the ECU. I already have installed the following: cold air intake (2.5 inch) ss header and 2.5 inch exuast to an N1 burnt tip turbo muffler (open baffel) 10 mm plug wires NGK V groove spark plugs new oem distributor cap new oem rotor bug short shifter 38mm stering wheel 17 inch alun mag rims coilovers top strut braces black halo headlights black marker lights black alteza tail lights aero dynamic body kit (in progress) the motor runs a little lean and some times hesitates on take off. it also feels to have verry little power. I have looked into doing a swap but I am having problems finding a suitable engine to use. any suggestions would be greatly apprecieated because I know that some of you gus know what you are doing, unlike me.
