Hello everybody! I have an upcoming project and i was hoping i can get some insight from you all. I have 2005 honda s2000 with a turbo greddy kit. Like the countless greddy kit owners i am tired of it so i want to upgrade. For my very near in the future project i have purchased a hondata kpro, 750cc rc injectors, 70mm berk hfc, 3inch down pipe, invidia q300 exhaust, a pfab greddy replacement exhaust manifold with a t3 flange welded on, garret t3 gt3076r .82 turbo, external tial wastegate, manual halman boost controller, and better clutch.

I am planning to do 13-14 psi. Can anybody off the bat give me an idea on how much whp i could probably make? Will i hit 380whp? I tried searching and it appears my set up is unique, i could be mistaken of course. Thank you all in advance for your time and responses.

 

3076R and 14 psi on a stock compression AP1/AP2 should yield 400-425 on pump gasoline, from my experience...

 

Sorry mate been there done that complete wast of money at 15 psi you might scrape 350whp then heat will be your problem,i hybrid my greddy turbo into a 600 hp turbo and managed 320whp at 13psi the log manifold is the problem causing heat so internal engine det is low,so more timing is needed this losing alot of power.Trust me go get a elm or side winder manifold and you will never look back.

 

Ditch the RC750 injectors. They're junk it's been proven time after time. ID1000s will not fail you.

I have a gt3076r on a pfab eltm at 10psi and I'm at 444whp

I ran this setup for a year or two. PM sent.

 

So if i were to get a elm what additional modifications do i need to do of whats left of the greddy kit? For example do i have to get different oil lines than what it came with, will the lines get in the way of what appears to be a huge manifold?

 

I just replaced the whole hotside with a fullblown stage 2 sidewinder ,you got to play to pay .New lines needed ,but keeping the greddy IC im getting full boost by 4200 rpm.

 

im putting down 310 hp with rc 750's at 6-7 psi on pfab log manifold.

 

I agree that you would be 350-380 if there's no significant knock. If there is significant knock (crappy pump gas), it could be a lot less. With a tubular manifold and that turbo, you could easily be in the mid-400's on pump gas.

Geeze how many times am I going to have to post this today?





There are undoubtedly better injectors out there than RCs, but they aren't "junk". There are plenty of people who have used them without issues, including myself. They work fine for lower output/budget applications. Personally, I wouldn't worry about upgrading the RCs until your tuner tells you that you need bigger injectors.
