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!

    • As I said, there's trade offs to jamming EVERYTHING in. Timing, resources etc, being the huge ones. Calling out the factory ECU has nothing to do with it, as it doesn't do any form of fancy boost control. It's all open loop boost control. You mention the Haltech Nexus, that's effectively two separate devices jammed into one box. What you quote about it, is proof for that. So now you've lost flexibility as a product too...   A product designed to do one thing really well, will always beat other products doing multiple things. Also, I wouldn't knock COTS stuff, you'd be surprised how many things are using it, that you're probably totally in love with As for the SpaceX comment that we're working directly with them, it's about the type of stuff we're doing. We're doing design work, and breaking world firsts. If you can't understand that I have real world hands on experience, including in very modern tech, and actually understand this stuff, then to avoid useless debates where you just won't accept fact and experience, from here on, it seems you'd be be happy I (and possibly anyone with knowledge really) not reply to your questions, or input, no matter how much help you could be given to help you, or let you learn. It seems you're happy reading your data sheets, factory service manuals, and only want people to reinforce your thoughts and points of view. 
    • I don't really understand because clearly it's possible. The factory ECU is running on like a 4 MHz 16-bit processor. Modern GDI ECUs have like 200 MHz superscalar cores with floating point units too. The Haltech Nexus has two 240 MHz CPU cores. The Elite 2500 is a single 80 MHz core. Surely 20x the compute means adding some PID boost control logic isn't that complicated. I'm not saying clock speed is everything, but the requirements to add boost control to a port injection 6 cylinder ECU are really not that difficult. More I/O, more interrupt handlers, more working memory, etc isn't that crazy to figure out. SpaceX if anything shows just how far you can get arguably doing things the "wrong" way, ie x86 COTS running C++ on Linux. That is about as far away from the "correct" architecture as it gets for a real time system, but it works anyways. 
    • Holy hell! That is absolutely stunning! Great work!!!
    • It does when you start adding everything else in. But it's not just compute. It's the logic. Getting your timing right (I'm not meaning ignition timing for the engine). Making sure of your memory mappings, seeing your interrupts. Microcontroller devices only have so much capacity. For the most part, you want all those timers and interrupts in use on your engine control, which means you're left with less than ideal methods for timing and management of other control functions.   Let's put it this way, my job is all about building custom hardware, that goes into cars, and integrates with them. We're also waiting on a media confirmation from SpaceX too fora world first we've just completed with them in NZ too. It's not just the little toys I play with. But you know, you can think and believe what you want.
    • I don't think it's a good buy, the trend looks bad     lol.
