Intercooler Pipes Upgrade
Price has not been determined because they usually sell these in group purchases.
The stock intercooler pipes are a HUGE restriction.
Front Mount Intercooler Upgrade
Road Race Engineering sells several different intercoolers that work great with their intercooler pipes.
Just ask Mike at RRE which is best for your application.
This computer from HKS converts the car from a MAS (air mass) system to a MAP (absolute pressure) system in the intake.
This gets rid of the restriction the MAS causes.
The VPC also allows you vent the BOV to atmosphere instead of being fed back into the turbo's inlet.
You will now be getting rid of the stock air canister and will be replacing it with a large K&N air filter.
Watch out! The turbo can breath!
After you get 550's and you use the VPC, you'll NEVER hit fuel cut again unless you make the VPC run insanely rich.
If you get 550's while using the AFC, you will not need a new chip.
You will only need to re-tune the AFC.
The popular 16G turbo can be purchased from a variety of vendors.
The 16G looks almost identical externally to the stock turbo.
You will be hitting fuel cut like crazy and needing more fuel than your stock injectors can handle.
Don't be fooled into thinking that your stock injectors can handle a 16G.
Running leaded race gas for 12 seconds is a lot easier on an engine than driving like I do everyday.
If you get a lot of boost creep because the mods you have added to your car is just too much for the internal wastegate, then an external wastegate is the only choice.
Turbo Trix sells a 95 exhaust manifold and Tial 40MM wastegate with the proper mount for a Galant.
This controls your boost and dumps the exhaust from the wastegate into the atmosphere.
This dump to atmosphere occurs at WOT or at boost levels at which the wastegate opens to maintain set boost pressures.
Extrude Honed Intake Manifold
Fuel Pressure Regulator
Adding a large fuel pump like the Supra pump causes the stock regulator to not be able to bypass enough fuel to create the correct fuel pressure.
