sup guys i need some help with my 91 crx HF. I want to get rid of the head and swap a vtec head on but is it worth it. Will it even make a difference and should I ditch the 4-speed transmission. Also can I just use a vtec controller or do I have to change my ecu. Damn this engine is super weak like a mofo. Please give me as many suggestions as possible. I know you guys must be tired of crap questions like this but here in Guam everyone mostly builds B motors. I wanna be different. thanks......
