MTCavity’s 2003 Galant Turbo Journal
I put this together over the build of my Galant and plan to keep on going, even though another model might be added eventually. Some of the future plans are GETTING NEW RIMS!!!, 5 speed swap?, disk break upgrade, coil-over suspension, EVO DOHC head swap, rod/piston upgrade, and would love to do a AWD (there are enough Eclipse’s that did the AWD swap and it’s about time a Galant does).
My other side project is ECU programming studies and the Open ECU Forums. “Johnathansgalant” has been one of the most active that I know on the subject and will hopefully someday be able to test out some other concepts behind engine management myself. The Galant in stock form is considerably an “emissions friendly” vehicle, where the ECU is programmed for emissions control, I would like to build a program to revamp the data to function like Haltech, AEM, Electromotive or Motec.
But without further “me me” BS, here is my “baby” and her upgrades.
As the G sits now.

Parts list and description;
PLX Wideband O2 (DM-5 digital display module/SM-AFR Wideband Air/Fuel Sensor module). PLX is not only affordable for the mild tuner, but will be right at home in the race environment due to the incredible expandability. It allowed me to tune in the fuel delivery with EASE. I will be replacing my EGT, Oil pressure and Boost gauges with PLX Devices.

Turbocharger pictures. Small .42 air .48 hot for fast spool low boost (I want 15lbs or less). I chose a smaller turbo for my build because of the nature of the 4G64 power band. Most of the power is derived from 2200 RPM – 5500 RPM, with a red-line of 6500. Stock HP is rated at 140 @ 5500, Torque (lb-ft) 155 @ 4000 RPM, out of a SOHC head with a bore and stroke of 3.41 X 3.94. Factory compression is just begging to be boosted of 9.0:1. Full boost is realized at 2400 RPM and can run up to 12psi steady, although I run it at around 9psi for day to day driving.

Cam gear. This will allow me to make timing changes "across the board", while leaving the "tuning" to ECU Flash. This is probably going to be tuned back or "retarded" (he he) so I lower the chances of knock.

Waste-gate, I will be plumbing into the exhaust system myself also.

Injectors!!! I purchased 2 sets not feeling very safe about the output. The left 4 are 335cc/min Bosch high impedance, while on the right are the make "me feel safe at boost" 450cc/min Lucas high impedance injectors, along with injector harnesses.

. If I could do it all over again, I would just have gotten E-Manage. APEX’i is pretty good stuff though, for the money.
