Why lower compression pistons? Personally i'd prefer some higher compression (ae101) pistons.
The cams mentioned might be a little big? coupled with low-comp pistons it might be an anus off boost.
I used a bog standard bigport GZE with RWD manifold. Standard fuel system (except pump), turbo manifold, oil feed line/T-piece, oil drain, water lines T-d into heater lines, custom dump/cooler piping, intercooler, no oil cooler. Same loom as GZE.
The only problem I have had going to GTE is overoiling the head and losing all its oil out the breathers at high revs. I'm assuming you wont have this problem though.
