Since I have this torn down, might as well do some upgrades. i have a question about injectors (like this hasn't been covered right?). Didnt find quite the answer I was looking for though. Since my engine was originally non-inter-cooled, but I have an intercooler now, is there a difference in the injectors besides being 9mm for 1st gen, or 7mm on the 2nd gens? Can I run 7mm injectors with sleeve on mine, or would it just be better to get a 2nd gen 12 valve head with 7mm injector ports? Any other input would be great also if there's a different way to go. Thanks!
It sounds like you are looking to make more than stock power... Non-ic heads are prone to cracking because of the bigger bore. I *think* the sleeve option is for better selection of nozzles, not necessarily less chance of cracking. Pop pressure is different regardless be between VE an P7100.
