coils won't get you any more power mate. only if your old ones are breaking down.

you'll struggle to make anymore than 350hp on a highflow turbo. you'd need something like a gt3071r or a hypergear atr43tggathkj. thingy. if you run any more boost than 18 you'll be out of the efficiency range of the turbs.

but looks like youve got most of the basic supporting mod!

+1 for big clutch.

ps keep in mind 400hp is getting close to the limit of the stock engine!

thanks people and i forgot i have a exedy heavy duty cushion button..any other mods i havnt done?

well you've only just scratched the surface and the mods you've listed are practically bare minimal requirements...

and as others have said you wont make your goal power figure with your list of parts...

I guess we could start listing suspension, brakes and cooling mods to make it so the power can be used and controlled, but Im sure youve already done that yeah, right, yep done that uhuh...

whats with this magical 300 number anways...?

why do you want 300?

Check out the hypergear thread if you want to keep the stock manifold and dump. Check out the kando thread if you dont. I vouch for the hypergear atr43g3, with those cams, you should see 300rwkw. You can install it yourself if you're confident enough and have some tools. I hear lots of stories about those return flow coolers overheating, not sure about the blitz ones.

    • 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
