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 cover 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 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 – Dark Blue
E.) TPS GND – Purple
F.) TP2 Signal – Pink[/QUOTE]

questions Looks good.
Does anyone know how this will fit with the Speed Inc. fuel rails?
On the injectors- is anyone making an o-ring/spacer kit to help with fitting injectors?
Finally- does anyone make a cable operated 90mm TB besides FAST? Can the stock on be bored out to 90mm?
Thank
Ben

Stock TB has a different bolt pattern. So, you will need a specific TB. It is a returnless system just like the stock Vette. You could convert it though.

Does the intake clear the cam sensor? What about the knock sensors? Im putting together a twin turbo 402 LS1, and was told this intake is the one to use! But when I go to buy one, they ask if Im putting it on a LS1, and said its too much work - stick with a LS6 intake.

Yes, we make the o-ring/spacer kit.

We are also making a Map sensor extension harness and MAP/Knock/CMPS adapter harness combo that should be available soon.
does anyone make a TB that will bolt onto that manifold without problem? The LSX intake will be prolly the only real option since it has the correct bolt pattern.
what about the older mustang style TB's? they have a 4bolt mounting, i just dont know if its the same bolt pattern? anyone, if a mustang accufab bolted up that would be awsome, as they are not terribly expensive.
