yeah i seen that site yesterday a little pricey but i guess when it's all done with that kit it should be bulletproof. and yeah i dont have mix match parts it should all be s14 parts. also a little off topic but my speedo has never worked since ive owned it i heard since its a s14 motor with s14 wiring i need something to make it work. dont know what i need the tach works and everything, just no speedo??
