It looks like you are using F23 head, F23 crank and rods then why not just use an entire F23 motor. Also, the Vtec on the F23 is a little different then other single cams.
thanks, i havent built a f/h b4 and the only reason i was thinking bout it is because i just have these parts laying aroundin in great conditiong. the reason i dont use the whole f23 is because i only have these parts. next question can i just slap the f22 vtec head on it, because my non vtec head is bad, if so is this like lsv or is this as simiple as putting a head on? can the f23 crank and rods and pistions work? is that going to be too high comp for turbo later?
