You *might* get away with safc - i'd check with your tuner. Usually if you change injectors or MAF you want a proper tuneable ECU rather than a signal bender like a safc, since the tuneable ECU will work a lot better. But, if you're happy with running an non-standard MAF with the safc and are tight on cash, you might be happy with slightly larger injectors as well. To an extent they can offset each other, so you'll require less signal bending with both in place. AFAIK, i could be wrong...

as for which injectors. i'd say go for s15 480cc injectors. nice upgrade, fairly cheap, fit straight in (still need tuning though)

buy used ones, but get them cleaned and tested before using them.

ignore all that. i didnt see its for a gtr.

Save you pennies and go for an aftermarket engine computer...

Worth it in the end, cos then you have endless upgrades.

I'd suggest: Power FC is prob your best option but if not, try a Haltech, EMS or Microtech. Have a look through those company's respective web pages and see what suits your budget/needs.

RE: injectors, depends how much power you are making, you didnt include any info on your power targets, boost levels, of size of your current (leaky) injectors.

RB26s use top feed if im not mistaken, so you cant use SR ones, some nice nismo 550s or sard/denso 500s would go well with a Power FC. Find a tuned and speak with them, cos im sure that combo, of stock turbos, big injectors and power fc has been tuned many times before...

Good luck!

hmm if you dont have a tuner near you then things get tricky...

i wouldnt suggest you tune anything yourself. tuning is a very complex thing, youd need a shitload of equipment, then the knowledge which comes from 10+ years of tuning a car, to churn out a decent power FC tune on an RB26.

you still didnt mention how big your injectors are...

it its leaking, check the o-rings are the correct size and that you've installed them properly...

where are you located mate?

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      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 😂

      Cas issue

      By GTSBoy · Posted

      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.
