What would be the best combo to make power to 8000 rpm? What cams at what lift/duration? What sprockets? What turbo? I'd like to make 270-300 whp. I don't care if it doesn't make power until 4000. I like some lag to stay out of boost while cruising. But a 3500-4000 rpm pull range would be nice. If your wondering what I'll use if for that would be fun. Just something to beat on and raise general hell. Thanks

You won't need cams to make power up to 8,000rpm

You will need a bigger turbo, injectors, engine management, fuel pump, exhaust, intercooler and tune

Turbo wise something like a HKS2535 would be good if your looking for around 300rwhp and its not that laggy either

ive got the KKR480 turbo... runs about 17psi. bit laggy, full boost by about 4.5k but turbo is still new so gotta let it settle a bit.. but apart from that.. car revs happily to 8500rpm with out so much as a tune yet

i got intercooler, exhaust, gtr fuel pump, remapped ecu and electronic boost controller...

Meh to valve springs and all that. Just get a nice turbo rated at around 400hp, something like a TD06, 3071 etc and get it well tuned with adjustable cam gears. I run a TD06 on a std motor and on plenty of occassions have ran it to a 8,800rpm rev limit with 18psi or so jammed into it. Though i tend to try and run either high revs or high boost, not normally both.

I know what supporting mods are necessary just needed some advice on good combos to utilize. Thanks.

I really have no good reason other than "just because" or the sound and to do it often. At least hit 8k in neutral, 2nd, or 3rd every day till/if it pops(I know I'm a ricer). If it does it can be rebuild. I love the power/sound/revs/price of the rb20. Its perfect for me.

Who here can mod the stock mani to use an ext wastegate? How much? Isn't the 20g what some dsms have stock but uses 3 bolt flange or what ever?
