LS2 intake asm will bolt on an LSX engine,
It will require
The new fuel rails and lower injector o-rings seals and .300" rail spacers to make up the different in height between the injectors.
The original current rail can be use with a buncha tweaking, but the new LS2 are a much larger diameter.
90MM LS2 drive by wire throttle body can be retro wired to current PCM and be fully functional.
Extend MAP sensor (use current lsx sensor ) wiring 21� to reach the front from current rear position.
Current fuel rail covers will not directly bolt on, but will with a tweak to the fuel inlet and some tweaking with a die grinder
All the current Brake Booster,PCV lines etc as well at the 4"OD inlet hose are the same.
90MM LS2 Throttle body will work with the following information
PIN ID LS2 90mm
A.) ACT2
B.) ACT1
C.) +5v TPS Reference – Common to both TPS’s
D.) TP1 Signal 0-5v
E.) Common Ground
F.) TP2 Signal 5-0v
98-04 Wiring hookup
A.) ACT 2 - Brown
B.) ACT 1 - Yellow
C.) +5 TPS Dk Green/Wht
D.) TP1 Signal – Drak Blue
E.) TPS GND – Purple
F.) TP2 Signal – Pink
Yes it works better and much cheaper than an LSX manifold, and the drivability of the 90mm TB is very good. The bell shaped entrys into the runners seem to work very well. They also moved the injector entry higher in the runner, so not it does not block the port roof.
PN are avail at your local dealer..it can be weasled if you know how. Should be avail straight up in less than 4 weeks. The only major snag for most will be the new style connector for the throttlebody. I suspect most will use the old style packard pins on them (they fit) and solder and epoxy them in place. The Delphi part #'s have not hit the market yet, it is the new corporate standard plugs so they will be used in a lot of different applications.
