hi all im only new to this site but badly need some advice i have a vr commodore (auto) with a awsome body kit but i just got a spare engine to play around with and wondaring what you guys think i should do so ill give you the 3 options and you can tell me what you thing and where i have gone rong and if you can give me a estimate on kw for each that will be great

option 1. keep it N/A with custon twin throtal body menifold, custom induction, bigger injectors, forged con rods, forged valves, forged 40 thow over flat top pistons, stage 2 cam and lifters, a little bit of head porting, extractors, valve springs and possibly yello terra rockers

option 2. i have a evo 6.5 turbo and a small garrett bb turbo which im considaring fitting both of them and useing the small turbo to spool up quick and the bigger for higher revs running at around 12psi obviosly have all the forged internals and low compresion 40thow over pistons and custom intake menifold basicly what i said in option 1 but with lowerr compresion pistons

option 3. same as option 1 but only use the evo turbo


thanks heaps in advance guys
