im building my g20 here are my current mods:
-bc 264 cams
-bc dual valve springs and retainers
-wiseco 9.0:1 pistons
-custom long manifold with a gt3076r
-tial 50mm bov
-tial 38mm wastegate
-calum realtime
-hks 720cc injectors
-competition cluch stage 5
-walbro 255lph
-street fire ignition
-aem water/meth kit

i think that is about it... what is the power im looking at with these mods? mind you im on pump gas(94 octane)

800hp easily...

550 max, you'll be restricted... no disrespect

ok realistically no need for smart ass'...

550whp? even with that clutch... i think the clutch is gin to be one of the main issues next to my transmission

How about instead of guesstimating, you take it to a dyno?

what MAF ae you running. Thats usually the limiter, then turbo, then fuel

I agree with 550, after that you won't get a tranny to hold any more.

B15, P11 will hold over 550 if you treat it right. Sometimes even if you do it will fail like everything else.

550whp? even with that clutch... i think the clutch is gin to be one of the main issues next to my transmission

Well that's just my guess... with a good clutch, the power band will climb faster with the power of the car and hold the power on top. But 550whp applied properly on the streets or the track is wicked. these days with the technology that's out there you don't need much to break great numbers. but again i could be wrong but i deal with a lot of EMS tuning on turbo cars and some of them still do surprise me. But I could guarantee you something, whatever power you make, after that change the log manifold to a EQL length or a long tube and you will gain 50whp. And the Meth Kit is a big ++++++++ :biggthump

thanks ye im *** scared that clutch is goin to blow out and then ill have to buy a twindisc clutch... i have a z32 maf... the car isnt together yet motor should be done thisweekend and saturday it gets put in and then finish it up...thanks guys

gl with the build keep us updated
