just did a LS vtec swap. have a 96LS. put a 97 GSR head on it! its turning over but wont start. i checked the compression only 50lbs. whats going on?! timing belt off?! head warped(hope not)?! need help asap! oh and if it matters i havnt touched the ECU or anything! all the wires and everything are from my stock LS. just want to get it out of the shop as soon as possible! would that be it?! i know the vtec wont work or anything but will that keep it from starting?! and what spark plugs am i suppose to be using?!
