so you just want some bolt ons? you could start off with an aftermarket intake, then header and full exhaust, my friend has an 88 si rex with those bolt ons and its pretty spunky, for the parts i would go to ultrarev.com, or at your own risk you could look at some ebay sh1t, the excedy clutches on ebay from gripforce are actually true exedy, my buddy with the crx has an ebay exedy and it definatley grips better/harder than my oem clutch
