Straight forward question... For a daily driver, ease of maintenance, simplicity of installation etc which would be the single to go for on a stock RB26, to not run more than 1.4bar or so and have comparable respnse to GTSS's.

Or is this just not ever done...?

Yeah, I'd be tempted to try and roll with a .78a/r GT3076R...

Thats the same turbo was suggested by beer barron in this thread 2 yrs ago.

but it never eventuated. So far all ive found with search is that URAS has a K5 on a rb26 thats setup for around 300rwkw.

Also aparently a factor when boost is approaching 1.4 bar is wastegate flow and boost control.

Seems there isnt too many people that head down this path.

Yeah it seems they are programmed into thinking that a good single turbo which isn't suited for >700hp is too small for a GTR, I guess it allows the "twin low mount" purists reason to believe that big singles are laggy. The reality is a GT3076R feels at least as good under foot than the stock R32 GTR ones yet is capable of substantially more power too - if you were going to go for an upgrade focussing on response with a measureable amount more power, a single GT30R I reckon would be the dogs bollux on a GTR. Don't tell a person about to drive it that its running a single instead of a pair of little twins and I doubt they'd work it out, aaside of course from the fact that a pair of GT-SS don't have a angry little anti-surge whistle haha.

Im really keen on a medium single for my gtr; i want it because of the gate, ease of maintenance and clean appearance.

After reading beer barons thread and seeing those dyno runs from URAS with the blitz single im contemplating the conversion.

Has anyone ever used a t67 from trust on a gtr? i know they run them on sr20's so im sure it would run responsive on a GTR

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • 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
