Instant response is required say 3000-3500 10psi at this rpm to 15psi at 8500rpm. Im currently stuck between a ATP modified gt28rs .82 T3 housed 4 bolt turbo (will flow more as t3 based) and a gt2871, will the atp version of the 28 get me to 350hp without dying off by our dyno standards here? (basically trying to make it as close as possible to a na setup but linear to 350hp)
what u guys think? or go the t2871 400hp version t3?

330-350HP at the wheels? or at the motor? I have the gt28rs on 7psi currently pushing 240hp atw's in my b16a2.
if i pushed it to 10-15psi i could deff be reaching the 330-350hp atw's mark. I love the gt28rs to be honest. spool time is very short. Not that much lag. I find it nice to be running in 5th on the freeway and to put the foot down and have power their to play with. With other turbo's ive had, ive needed to drop back to 4th to feel any significate power. But the gt28rs does slightly die out after 6 thou. But the Vtec is their for the rest :)
atw just want a nice linear graph with lots of area under the graph...
keep in mind these gt28rs are t3 .82 so bigger than the t25 flannged variant. motor will be running wiseco pistons prolly around the 10cr mark, skunk 2 im or victor x, 38mm tial gate, 2.5in cooler piping, valves springs retainers undecided on the manifold as yet but eithr ss log, mini ram or ramhorn (want to try run a full size radiator as will be for circuit if i can)
Dont get the 2871R. Either stick with a .82 28RS or go upt to a .64 GT30. For road race though, i would choose a 28RS.
Oh and those HP estimates are all flywheel. Dont U wont get anywhere that at the wheels. For upto around 220kW, get an RS. for over 220kW, get a GT30.
hmmm shit, whats the spool like on the gt30 .64 i need good throttle response but also hold its own up top to 8.5k rpm need a power band of around 3-3.5 k to 8-9k rpm with nice linearish graph suited to a monster of a road/circuit car
If you going to use it on the track, why do you do you want low end response? You be above 5k rpm all the time.
low speed, 2nd gear corners...Quote:

basically im trying to replicate a na setup as much as possible with the power delivery but have 330-350hp on tap.
Manifold is a min-ram with 44mm tial gate 3in dump which is coming in 4 or so weeks.
If you wanna replicate an NA power feel then just get a High end supercharged setup. i don't know if it will get you to 330-350hp but it will be close with alot of mods.Quote:
