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]

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

I asked speed demon about the stock TB being ported to 90mm and they said no. Give it time though. The new corvette still isn't on show room floors, they will have something. Watch.

Is that a return line on the fuel rail? If so, where's the pressure regulator?

J-Rod

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.

Is the GTO TB drive-by wire or is it like the Fbodies TB? And how can we use a normal TB set-up for our Fbodies?

So how does it perform compared to an LS6? LSX?

But will it fit under the cowl of an F-body?? Looks real tall.

Its just about the same height as current.

nice, let us know when there is a power comparison.

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.

Thats what I was thinking, unless power is huge, thats a lot of custom work what the FAST or LS6 could do.

To many things to do to get it to work, That why I'm selling my LS2 intake never installed.

so the LS2 fuel rails are not a direct bolt on ?

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


It is with the spacers.




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.

My Nick Williams 90mm TB bolted up just fine using all 4 bolts.
