For me,
Bottom end:
Standard rb26 crank, nitrided, chamfered oil holes, Standard rods resized and shot peened,
Hypertectic pistons, id have to look into brands before deciding, but i do not believe forged slugs are required, pistons to suit 10.5:1 comp with valve relief's, steel comp rings, low tension oil rings, restrictors fitted to oil feeds and head/block returns drilled out
Head: stock valves, heavy springs, cams 260/262 10.5 lift dialed @106/110, a good throat job and trim valve guides, head decked to suit chosen pistons,
Turbo and pipes: small diameter high mount turbo manifold, hks 3037s, 50mm gate with 2inch open screamer, 3 inch dump, no cat or mufflers, strait to the rear
2.5inch stainless cooler pipes to replacement factory sized cooler, water/meth nozzle directly before inlet to plenum,
Id run 18-20psi, i believe a good tuner could really lean on this combo and make a rediculasly responsive weapon that packs a punch
Hmm, first question to get a post out of me in a while lol
