420A Engine management required for 300hp

[James Browning]

I currently have a 96 RS that I am in the process of fixing up to get it running. I have a few mods planned after that, and I am wondering what I will need in combination with these mods in terms of Engine management to get me to my goal of 300hp. This will mostly be for autocross so that's why I'm going for a 16g as opposed to an 18g or 20g. Also I know that I will need to get a Walboro 255 (and maybe bigger injectors?) but what else would I need to get fuel wise. I know that there are a few threads on this but all that I really want is the bare minimum required for 300hp and I am unsure on how extensive that will be.

Mod Plans:
Forged Wiesco pistons
Eagle Rods
Also some of the less expensive engine parts I will replace because I might as well if I'm taking the engine out
16g Turbo (obviously with all the non-engine management things required for this such as fmic, exhaust manifold, oil lines, etc)

(I think this is ok but this is my first time starting a thread so please let me know if/how I can improve)

The most reliable way is to go with megasquirt (plenty of documented info out there) or an AEM FIC. Dollar for dollar the megasquirt is the better of the two.

The cheap way to go is to use an fmu which raises fuel pressure based on boost which basically tricks the ecu into injecting more fuel (due to the higher fuel pressure). This is also a very documented method. It less desirable.

Oh wow, I've read your thread more times than I can count man. Your build is really inspiring especially after all that trouble you had at the beginning! Why would the fmu be less desirable? Is ECMLink an example of an fmu or is that something different? I've read a lot on ECMlink and all but I'm still unsure whether It serves the same purpose of the megasquirt or something else.

Found another thread you posted on and answered my own questions, thanks a ton for the help though and pointing me in the right direction!

Thank you. I'm glad you have found my build thread inspirational.

Best of luck with the build and keep your build thread updated. Not many 420Aers left on this site.
