So heres the story, a friend came to me asking me to design him a custom turbo kit for the mazda protege5 wagon. And i have been thinking about the fuel system. I have alot of experience with turbo hondas and i also own a mitsubishi eclipse turbo.
Never the less i run a very cool, cheap, and easy fuel system in my turbo honda.
Here is the parts you will need
Large fuel pump
apexi SAFC (add on fuel computer)
Larger fuel injectors, say 40% larger. I used 450CC eclipse injectors in my civic.
The idea is....with the larger injectors and your AFC set at -40% for fuel, you lower the MAF input signal so far that you extend the maxium allowed MAF input signal. This allowed for 10psi of boost on my honda and im guessing similar results on the mp5.
The end result is very very smooth power, silk like 1/2 throttle driving. For a low boost application (10psi or less) its awesome. Nothing is as good as the stock computer..so why not just use it?
The eclipse guys use this same type of setup, increase the fuel injectors and lower the MAF input so they dont hit fuel cut as soon. No reason it wouldnt work on a mazda.
Here is a write up i did on honda-tech.
