Sounds kinda like the 3SGTE Supra on Hi-Octane... lots of dollars tho and they did it for weight distribution reasons. Its not a good idea for $$$ reasons if thats what you are thinking. The conversion would be soooo expensive, you might as well make the RB tougher.

Off topic,

Though i think Top Secret picked the 4 cyl to mimic JGTC rules, in which you can run higher boost.. - i think.

You have an extra half a litre of displacement and a cast iron block. I'd say you've got a good chance of getting more bang for your buck with the RB25 than the SR20.

It might cost a bit less to maintain, but considering no-one does this conversion all your bits will have to be custom....which will cost you a fair amount. Your TCO will inevitably be higher.

As everyone else has said, unless you're prepping the car for motorsport and you want to weight balance gains (and perhaps rules on engine displacement may affect you) I can't see a gain.

Nah the SR20 will have such a hard time in a heavy body, especially if you get the old S13 Red top with no NVCS (variable valve timing) which'll make off boost torque even worse. The good thing is that aftermarket parts are everywhere, but I'd still take the RB25 anyday. Hell I'd love to try a RB25 in my S chassis!!

    • 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
