for cheap intercooler kits hit up justjap for the stealth piping cooler kit, no need to drill holes in batter tray & it doesnt look messy with piping running across the fan shroud.
Yep i meant a perma-cool relocation kit with a few extra hoses & cooling pro core (will have to buy the proper fittings to fit the hoses on as they arent screw type like the braided ones) was going to get a B&M core as well but i found out doing it this way is heaps cheaper.
you can run a ext gate on lowmount, just need to get your lowmount manifold modified for the ext gate.
your turbosmart boost controller will be able to keep boost levels at 7psi.
as for injectors, i believe R33 GTST ones fit too. that might be an option for you and theyre easier to find as well.
if you shop around & take your time, you can get all the parts required for this conversion for arund $2000ish + installation & tuning with aftermarket parts (only stock thing is the manifold & injectors - cheaper of course if you use standard smic & exhaust)
