Keep the 20 and highflow a standard 20 turbo. Mine makes 219rwkw with a rb20 highflow, injectors, front mount, bigger fuel pump, microtech and full exhaust.

You've already got exhaust and front mount so all you need really is to upgrade your fuel system, tune, afm and to get a turbo that is capable of more then 15psi and you'll have around 220-230 rwkw.

Fuel pump $250

AFM $200-300

Injectors $300-400

Tune $850

Highflow $800-1000

Cam gears $150 plus new high tensile bolts $5

Easily done for under 3k.

I'd sell the rb25 turbo as there fine when standard on a 20 but once highflowed forget about it, way to much lag. Either a rb20 turbo highflow or hks 2530 is best for a rb20 imo. RB20 turbos are what like $50, hyper gear will do a high flow for around $800 and your laughing.

Get some cam gears to, thats my next mod. Apparently helps heaps with bringing on boost. I had some on my last car (hr31) untuned and i noticed a fair difference in power delivery.

I have gtr injectors and the resistor pack for sale to if your interested :thumbsup:

If you going to rebuild something rebuild a 30

if you dont need to rebuild then stick with your 20, just make sure you only buy stuff you can use when you get bored with the lack of torque.

    • 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
