Hi,

Looking to do a swap from my HKS GT-SS setup to a Single on my GTR. Don't really want to fk around with having everything made up custom work etc

what companies make off the shelf single kits for the rb26?

I know HKS make the T51R kit but i think that is way to huge (looking for 400hp ish)

400hp.....is that a typo?

nope.

ideally i like to stay with the twin setup however, after rebuild them 2x now, and having issue with the std fittings i am just sick of the setup and working on it isn't the easies thing to do compare to a single

I don't want to to push anymore than 400 maybe 450hp max because the car is predominately a race car and with the known oil issue in the rb engines i don't want to lean on the engine too much.

i'm currently making 370rwhp @ 18psi with the gt-ss power is limited by my injectors (600cc @ 90% duty cycle, then need to be clean and flow tested)

Also i do miss the gate, and the way a single makes power compare to twin setup... i find the gt-ss laggy

Big sump and sort our your catch can/vent setup. People still turn bearings on standard turbos and engines.

600 cc @ 90% for 276 kw at the treads... Something wrong there. Rebuilding them x 2, something wrong there. SS's laggy? Wow.

Find someone to fix the setup you have, there is something wrong.

as mention my injectors need a clean, i had been using them for 2years in my previous track car before i put them into the gtr and they were bough second hand. When i had the car tune i wasn't interested in upping the power as i just wanted more seat time but since then the car hasn't been driven for almost a year and only recently have i started working on it again

rebuilding the turbo 2x nothing wrong... 1st time was because they had done the bearings, second time my filter let go and destroy the wheel.

I find the GT-SS laggy my previous track car was single turbo rb25 with similar power. Also doesn't help my other track car is an evo which has insane levels of responses

i understand this but the car has spent more time sitting in my garage then driving if the sump was to come off i know it would soon turn into a very hardcore build which atm i want to try and keep as simple as possible. The car was already achieving good times at the track with n1 turbos and std ecu.. i just wanted something less laggy and more reliable hence i went with the gt-ss

Push a Garrett GT35R/T04Z to 400kw+.

FY,I GCG sell both of these as a kit with a manifold, gate and other bits and pieces. No dump pipe though.

thanks will check them out

I was getting full boost (20psi at 4500rpm) even though my dyno graph shoes 4800rpm lol with -7's.

Running a GT35 now and its on full song by 4300rpm and makes 80hp more on the same boost.

It is possible there was something wrong with my old setup in terms of response but they were making the power they were meant to be.

It wasnt the turbos or actuators but Im done thinking about it, quite happy with the single setup im running now!.

    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
