Has anyone done a LS1 TB swap yet?

[JonZ71]

That's exactly what im probably gonna have to do... lol

 

[JonZ71]

Heading down to my buddies house tomorrow where we are going to grind down the shaft and then flatten out another portion of the shaft to make it work.

 

[JonZ71]

Boom. I'm done. I had to cut grind and weld the end of the shaft to make it work for the tps sensor. I got it down to .3% tps. Thats the best i could get it so im leaving it lol

I have never done them that way. I grind the weld off of the LS1/Gen3 throttle body at the cable attaching arm. Then rotate it and match its clocking to the smaller Vortec throttle body. I tig weld it and try not to introduce too much heat into it. Too much heat can warp the shaft and fatigue the spring.

Lex, are you talking about the very end o the shaft? I still got another shaft sitting here that i may mess with some more.

 

[JonZ71]

I keep throwing a p0122 code which is tps a circuit low input or some.. What does this mean

Lex, are you talking about the very end o the shaft? I still got another shaft sitting here that i may mess with some more.

Yes, Where the cable arm is welded to the shaft.

I gotcha. Well im still trying to figure out this damn p0122 code.

 

[JonZ71]

I gave it up lol, getting a new throttle body tomorrow

So you gave the whole deal up?
I was kinda wondering how you where going to go about getting more fuel since you have now incresed the air?
And I mean that as if you where gonna finish it out and use it.
