Hey guys, Im about to send my block to the machine shop to get sleeved and machined and all of the good stuff Now i need to pick which head to use. Im not sure how much boost i will be running but im pretty sure that it will be 20+ on ocasion but probably less than that on a normal basis. I was debating between the GSR, ITR and CTR heads. What do you think is the best choice. And which one would i be able to get the most power out of with the lest amount of machining for the money?. Also I have a guy that wants to sell me a bare brand new ITR head for $500 so should i do that and just buy the internals for it that are good for turbo?
THanks JMAN
