Post up what you'd like to achieve (and the budget!) and we can offer some advice.

Try to set out what you want to do with the car and set a reasonable / specific goal for what you want to achieve - what you need to do / buy then flows from that.

 

Trex is on the money, read up on some of the other build threads or dyno results threads under "Forced Induction Performance" to see what others have done and it will prove invaluable to see what needs to be done and gives you an idea of the sort of costs / parts involved to get to that power level.

At an absolute minimum you'd be looking at:

$800 to $1.5k+ for a turbo (depending on what you want + extra if you decide to go for a better manifold)

$1250+ for a plug in like an adaptronic / nistune / link etc plug in

$600 for decent injectors

$200 for a better fuel pump at a minimum

$500-$1.5K for misc crap  for making the above work correctly or fix other problems you come across while doing it

$1k - $2k for a clutch to handle the increased output (if required)

$??? for any workshop work to fit the above (if not swinging spanners yourself)

$??? for tuning - highly dependent on who you go with

The AFC is a nice bit of kit when turning up the boost a little on a standard car but at ~450hp at the wheels you are going to be asking for a lot more than what the AFC is capable of safely / sanely doing. The plug in will give you much more flexibility and safety in the tune, not to mention being far easier to tune and a better base to build modifications off.

I have never used one personally but I am well aware of how it works. The sort of modifications that you are looking at is well beyond what this would be able to handle as it is really only meant to be able to manage fueling on a relatively stock engine and not deal with massively different injectors and a much larger turbo etc.

With what you are doing the nistune is an absolute minimum and really the engine management path you take is sort of dictated by who you are getting to tune it - you will get a better result using what they suggest / prefer rather than one they dont know / can't tune properly. 

If you are poor don't buy rubbish you don't need. Just try to save up a few grand and in the meantime do some reading along the lines of what you have been advised above. Sell the AFC Neo.

Just to spell it out none of the items on your list will make your car go faster.

And don't feel bad that you don't know enough - we all have to learn - some of us the hard way by spending a lot of money that could have been used more wisely - so don't be in a rush - you can't do much until you can afford a bigger turbo and the bits needed to support it so just keep researching and saving!

    • 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         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
