LS2 Intake and TB??
1 - 20 of 20 Posts
They are direct bolt on. However, the wiring harness and adapters are not the same.
The LS1 has the map sensor in the back of the intake where the LS2 is in the front. So, you need a wiring harness extension.
In addition, the LS2 TB has a different connector and thus you need a wiring adapter for it also.
Hope that helped.

I did notice that the TB for the LS2 is not cable operated. It is operated by electric motor. It also said... "It also eliminates the need for an idle air control motor, cruise control module and the "throttle relaxer" for traction control."
Does all that make it not possible to use on the LS1, or is it a very involved process to make it all work?
Also, where would I find the lengthened adapters for the sensors?

I can't speak specifically for the LS1 - LS2 swap as I've only done an LS6 - LS2 swap. However, I was thinking that LS1 cars were throttle by wire also. I could be wrong.
I think I got all of my cables thru SDPC. I don't recall exactly as it has been a while since I bought the parts.

also the ls2 injectors are different. the ls2 are shorter and fatter, and have different connectors, thus you would be able to use the same fuel rails.
So are you saying I would need to use LS2 injectors but the fuel rails can stay the same? Or do I have to change to LS2 fuel rails as well? Thanks!
To tell you the truth I am in to factory looking racing applications! I understand the fast products are good, I am just after a factory look!
I have quite a few friends with different modified LS1 F-body cars who have the different aftermarket companies products all over the place....their cars are very fast, but everyone knows it just by looking at it! I am after a factory looking engine with plenty of extra power.
My plans are to buy a set of LG Headers and an LS2 intake manifold. I'm going to take my factory heads, the headers, and intake to a local professional shop and have the heads CNC port matched to the headers and intake... To go along with the porting job on the heads and the LS2 intake manifold i will put a 90MM LS2 throttle body on it. All of this combined with a new cam of course and some rear end gears and I will have a very quick car that appears to the eye to be factory....with the exception of headers!
This is what I'm after so I can kick some but and look stock doing it!

honestly, stay away from the fly by wire BS, its to much trouble, if anything find a way to convert it to the ls1's throttle linkage, you should be able to use the same plate from the ls2 tb and mount it on the ls1's shaft hopefully... either that or just use an adapter for the ls1 or ls6 tb
Do you have only one fuel rail, or both?
The fuel rail is a one piece assembly.
