Have bet with buddys.What do you think?
You can see the list of mods I have in my signature and I am about to upgrade to Rtek7 2.1,add boost controller and put 550's back in as primary injectors.When I take it to get tuned (between 10 & 15 psi) what kind of numbers do you guys think I might make?Me and two of my buddys at work have came up with some numbers but I wont to know from some people that might a little better.It's killing me I have to Know I can't wait.

I'd get a boost controller, a fuel pressure regulator, port the wastegate, and a fuel controller.
otherwise, running that car at 15psi all the time will definitely make the engine go boom.
my old 87TII did 244whp with similar mods. but i had a boost and fuel controller. I also did the tuning myself.

^^ he said he wants to downgrade from 720/720 to 550/720. I am telling him that that is not necessary, and in fact he might as well keep that injector combo in case he goes with a bigger turbo later. I am also telling him that 250rwhp is the practical max hp for a stock turbo.

you're gettin 15psi on a stock s5 turbo w/ stock ports?!?!
I have mild streetport, s4 turbo,2.75dp, midpipe, and cb.fuel controller and im only boostin 8psi max... somethings wrong...

my 88t2 will creep all the way to 11psi without a boost controler. its because the wastegate can't flow enough to drop the boost. all i fhave is midpipe and cat back. still have stock precat(i promise to replace that soon, car came that way).
if your's is ported then you'll definately need to get a boost controler. if not....then your turbo might be on the outs. pull your intake elbow and give your turbo a little spin with your fingers...it shouldn't have any resistance. pull on the nut and see if it has any play in it.
anyways...my guess... 212RwHp!!! hahahaha

Well i just got the Rtek7 2.1.Also a boost controller and M-spec front mount intercooler and hardpipe kit because my tune guy said to.He is telling me that he should be able to get me 290rwhp at 12 psi easy with my mods.Hope he's right.He does tune Rx7's for a living.

Top Down, Boost Up

That being said, if it is in fact a hybrid turbo and you pull out those 720s and stick the 550 primaries back in, you'll almost certainly run lean. Like arghx said, the Rtek will let you run the 720s properly and give you enough fuel to supply a small hybrid turbo.

Well I am going to keep the 720's in and i don't about the turbo as far as I know it was stock but the boost never falls back so maybe it is small hybrid .About ktunes thread besides the port I have a little more done then he has listed.
-M-spec front mount intercooler kit
-Greddy RS BOV
-3" intake
-Full 3" racingbeat exhaust
-720cc injectors
-Electronic boost controller
-255 walbro fuel pump
-9mm spark plug wires
-ACT racing clutch(to help get more of the power to the ground)
-Rtek7 2.1 (for real tuning)
-And steady boost all the way to redline
-Oh and 93 octane fuel
He listed 2.5" exhaust,injectors,font mount and afc.So I would think I could get a little more whp which would put me close to,at or above 290whp.
