it's a manual RB25DET equipped GTS-T, seems to have the 'super HICAS' on it, whatever that is :P ....and it has one of these little f**kers on it, which I've no idea what to do with..

how do I set it up properly, the boost on both settings seemed to be wound ALL the way down so it made all the funny turbo noises with no power produced :P

I don't know shit about turbos OR skylines really since I've never owned either. Educate me!! :D We smashed some new oil into it today, replaced driver's seat that had a rip in it, and gave it a quick backyard spec alignment (was way off, probably due to something i haven't worked out yet being bent..) and it seems to be going alright. Tried winding up the boost on the high setting a little; seemed to work somewhat but I'm worried about leaning it out because I know nothing about these things :) is the factory boost gauge usually fairly reliable/accurate?

Anything I should be looking at changing immediately on purchase? Was thinking plugs and leads but I fail there because it doesn't have leads :) lol..

Anyway interested to hear ideas on how I should approach this! I need to learn a lot about this car.

Thanks

Sam

the factory boost gauge is far from accurate, and you should also note that it doesn't read in PSI. first thing you should do before playing with the boost is get an aftermarket gauge.

as for how much boost you can run, that depends on your mods, but if it's still running the stock ecu then if you go too high the ecu will start to work against you. you shouldn't have any issues with it leaning out (unless the fuel pump is shagged) but the opposite. the stock ecu will make it run rather rich.

got RWC today.

turbo timer is on the to-do list, along with figuring out why it doesn't like WOT..

any recommendations on brand for the timer?

Coilpacks are Splitfire, look brand new, and I replaced the plugs with NGK BCPR6ES as recommended by an antilag member.

Boost gauge definitely on the hit list, need ideas on where to mount a few gauges as well as types that don't look too homo....

      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

      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
