built turbo gsr. how much whp??
i'm in the process of building a new motor for my car. i have a b18c1 block with an 81.5 mm bore and block guard. i am using eagle h-beam rods, forged arias flat top pistons 10 to 1 compression, stock gsr crank, acl race bearings, arp main/head studs, exedy racing flywheel, act 6 puck sprung clutch, gsr head with 5-angle valve job, black nitrate valves, dual valve springs with titanium retainers, gsr cams, cometic head gasket, skunk2 pro series intake manifold, 68 mm throttle body. also, walbro 255 fuel pump and rc 550 injectors, hondata s300. full 3" exhaust with test pipe. i am looking into getting either a gt2871 or gt3071 with 3" downpipe and 38mm tial wastegate with ramhorn manifold.
what kind of power can i expect to make out of this setup if i'm running 8 psi daily, but also tuned to 15 psi? will the 550 cc injectors be sufficient or will i need 750cc? does anyone know how much lag i can expect out of these turbos? any input would be appreciated. thanks.

550cc injectors are good for about 350whp you will likely want to get something larger like 750's or 880s. dont get so caught up with psi, it means pretty much nothing. set a power goal.

Re: built turbo gsr. how much whp?? (TheShodan)
with the parts that i'm using in my build, how much power can the block handle? my goals are to build a motor that can possibly handle 500 hp, but run it daily at around 350whp.

lol, but it also depends what turbo the OP is using.

Re: built turbo gsr. how much whp?? (VTECth1s)
so far i am leaning towards the GT2871r because i'm told it will spool up faster than the 3071. i'm hoping that this turbo can make 350whp with no problems.

that still wont work. what if he gets another block and it blows up sooner than the first one ??? or what if it blocks up way after the first block, the OP then has a bad generalization
