wut kinda power gains am i looking at if i swap an itr head with jun valve train 2000 usdm itr cams itr gears jg manifold 65mm tb aem rail and reg and hytech header on to a stock jdm gsr block

 

without a tune i say somewhere around 180 to the flywheel

 

thinking about that again, probably closer to 190

 

ok so wut abt on a tune with hondata s200 and with cold air intake world sport 2 exhaust and full msd ignition

 

10000000 hp! Dude there is no way to acurately tell unless you dyno tune the thing. Everyone can guess but it wont make any difference if you dont get it setup properly. Plus why do you need an MSD ignition and AEM FUEL RAIL AND REG? Is this making near 500 hp? If not then your stock stuff will handle that setup.

 

the stuff is coming with the parts i bought and msd was already instulled on the car with a 2step...i just wanted an estiment on hp i wanna get 200 whp but im thinking ill be more around 180 idk

 

i would say somewhere around 180 prolly less, i had an ls/v with skunk2 stage 1 cams and it bearly made 180, and that was with 12 to 1 compression

 

my set up now only put out 185 with the same cams as last setup and 6lbs of boost

 

ya I doubt ur gonna get 200WHP without doing something to the block itself.
