I agree with nemo on the CHRA.. the only time this is a good idea is if it is a GARRETT BallBearing turbo, i.e. 530bb or 700bb otherwise if your stockers fail.. upgrade. Get some decent breeze clamps that you can tighten down do avoid boost leaks. As far as heads go ARP studs is the way to go. Check FAQ clean and lube your IAA and IACV on the back of the plenum. Might be a good time to ohm your injectors make sure all of them are in spec. you will need lower and upper gaskets, use your old ones to portmatch for added flow. Pick up a set of JWT VTC springs. Everything i mentioned is more a list for you to do than parts. Unless you are digging into the bottom end you should be ok with what you already have. Nismo Thermostat might be a good thing as well.
