i had install a 90 crx si camshaft in my in my friends 93 civic dx last year and he swear that it made power but now the car is total. he just bought another 93 dx and wants me to install the crx si cam in there again. i need to know if anyone knows or think it will make any power at all. if its a waste of his money to pay me for the labor, i wont install it.
