All of the work done to my Galant was performed by me, in a persuit to understand engine managment and turbocharging concepts. I would like to thank the members at The Galant Center, TGC is to this day, an astounding help! One of the most active and involved group of Galant owners of any forum I've ever used. If not for them my Galant would be stock! Thank you all...

The Galant Center (TGC)

Recent pictures of the Galant (and always being tweeked in a new way).

It looked like this up to the summer of 2007.

TURBO BUILD

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.

SM-IAT (Intake Air Temperature - Sensor Modual)

SM-EGT (Exhaust Gas Temperature - Sensor Modual)

SM-AFR/DM-5 AFR (Air/Fuel Ratio - Sensor Modual/Display Modual)

They just came out with a new product DM-100 Digital monitor. DM-100
Intelligent Multi-Functional Display (iMFD)
Universal 2 1/16" (52mm) OLED Color Display for all PLX Sensor Modules. Here are some of the features.

Customizable gauge styles, backgrounds and colors
Analog, Digital, Graph, 4 Parameter styles
Organic LED display
Set peak and hold points
Intelligent warning
Daisy Chain up to 32 Sensor Modules
Simple to Install
PC Interface Software Included
Comes with Remote Control
(Also offering sensor/gauge modules for IAT, EGT, Vacuum/Boost, Temperature, and Fuel/Oil pressure with probably more to come)

I will have mine before the end of December. Knowing the state of my engine systems control and feedback is absolutly important to me.

The highlighted is my 2003 Galant ES ECU Block diagram.

Timing belt, balancing shaft belt, timing tensioner bearing, balancing belt tensioner bearing, and timing pulley bearing. I love you NAPA!

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.

This is an exhaust manifold for a 4G63t, but mounts up to the 4G64 like rabbits in April.

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.

Wastegate, I will be plumbing into the exhaust system myself also.

Blow off valve, not installed.

BOV dry and ready.

Turbo oil line kit, supply & return lines and fittings.

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.

This is a TRE-Performance 255 lph (112 psi max) fuel pump and relay for wiring a constant 12 volt+ and higher rated amperage power supply line.

OBX enlarged fuel rail for the 4G63t. I had to "enlarge" it a little more myself, more on this later.

FPR, Vacume lines, Fuel Lines and Fittings.

Intercooler and piping, although I will not be using the couplings sent with this kit and purchased Polyester Re-enforced Silicone Couplers.

This is a the approximate turbo base mapping for the setup I am running. I will "rough tune" with ECU flash, then fine tune with SAFC NEO while using NEO to also tune in my fuel for boost.

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.

Oil Catch Can - Prevents oil buildup in throttle body and intake manifold.

Hayden Tube & Fin, Power steering cooler.

Oil cooler (Bar & Plate) and filter relocator, I am still waiting on a thermostat to allow for quick warm-ups. Installing this looks fun and yet complicated. Like I did not have enough crap under the hood to take care of...

Hayden Bar & Plate, Transmission Oil Cooler.

New MAF adaptor, the K&N 5 1/2" will be too hard to plumb into the intake/intercooler system.

Stainless Steel Flex piping, 2 sections of UJ mandrel bends, 2-5ft sections of straight piping and 3 flange kits for exhaust. I plan on breaking it down into 3 sections for easy removal.

VIDEO
Fast ride over Blue Mountain, 35 deg grade. The turbo keeps me from down-shifting like the NA. It is not a insane ride! There were others on the road, so I kept the speed reasonable.
