Yes, you can get the manifold with or without an intercooler. I wouldn't waste time getting one without.
Terminator Intercooled Kit for the '99-04 GT
Included:
# Aluminum lower intake manifold with remote coolant thermostat housing.
# High capacity intercooler resides inside the lower manifold directly below the customer provided '03/04 Cobra Supercharger.
# Front engine cross brace assembly that provides a independent 8-rib supercharger drive assembly with all belt tensioners and idlers.
# 7" lower piggy back style crank pulley that attaches to the factory pulley dampener to complete the separate 8-rib drive belt assembly.
# Installation is straight-forward and can easily be completed by any DIY enthusiast with basic hand tools in a weekend or less. Our detailed Installation Instructions are shown on the left side of the main page, or see the link below.
Also needed:
# Terminator Supercharger with pulley and appropriate belt.
# Larger fuel injectors to meet what ever HP/TQ level you achieve. We expect most who use this kit will easily achieve 350 to 400 HP, depending upon boost level so TTI suggests at least 39 to 42# injectors.
# Upgraded in-tank fuel pump.
# Air to water heat exchanger.
# Fluid pump to transfer coolant between the intercooler core and the heat exchanger.
# Fluid reservoir to allow for a place to add coolant and check fluid level.
# Coolant lines, hose clamps, engine belts, etc. are not included since we do not know what you plan to use for a heat exchanger, or where you will be mounting it.
# Complete intake assembly, such as a throttle body, intake tube, MAFS, and filter.
# Custom computer tune
^^I have seen ALL of these things (minus the tune) sold at one time on Ebay for less than $1000, on multiple occasions.
Last time they had the price listed, the intercooled manifold was around $1900. So $1900 for the manifold + $1000 for the blower and accessories + $300 for a tune + $300 for miscellaneous stuff you always need =
$3500 total. Pretty sweet deal for a PD blower when you consider it'll be at least a couple thousand more for a Kenne Bell.
