DIY Turbocharging and Modifying an Automatic Protege5

[MuffinMan06]

Added 440cc injectors and the AFR goes from 13 when nearing boost to 10.5 at the full 6 psi. Build complete minus some fine tuning (for now).

If you don’t mind my asking, what. Tune are you running right now? I’ve been running the split second for a little while now and I keep getting into the 9’s on my afr. Still working on the tune.

Surprisingly I set every box to 10 while pulling 1 degree per psi with the splitsecond kicking in at 0.5 psi and the automatic ecu maintains 10.5-11.5 under boost

Nice! I may have to try that after i finish converting the hardlines with an fittings.

Info for y’all regarding the transmission strength. If you have a 2003-2003.5 model year car with the auto, it comes with upgrades such as:
-Single sided frictions
-higher performance friction material
-Single piece bonded pistons
-higher performance torque converter clutch material
-compression seal pump vs old o-ring style
-updated accumulator piston

Shouldn’t slip below 180 lb/ft

Also, the metal stator, heavy duty sprag, and lock up clutch can likely be sourced from a ford CD4E torque converter

Picked up a vortex’s FMU because the ecu was freaking tf out after 500 miles since the 440cc injectors cause it to max out the fuel trims.

Which Vortex FMU did you get, 12:01?

I believe mine is 10:1 so I will be going back to stock injectors

Is your MAF and Air Temp sensor in the stock MSP location or is it located right before the throttle body like a regular Protege?

Relocated my maf to right before the Throttlebody and the temp sensor is right after the air filter
