LS TB on L67/ecotec

Hi guys,

What are people doing for the vacuum sources for things like the purge solenoid and charcoal canister as the LS TB doesn't have the vacuum ports on the side like the V6 TB does?

The purge solenoid comes from the charcoal canister above the diff, so there should only be one vacuum hose. I’ve seen them put brass fittings straight into the elbow,but on my old car I drilled through the side of the adapter plate that I made and fitted a press fitting in there like the factory one in the tb.

What ubend are you using and if its the stock one what adaptor plate are you going to run.

I made my own adaptor for the stock ls1 throttle body and drilled the adaptor for one fitting and cut out a section of the plate so the fitting on the throttle body worked

This LS TB is on a mates VS L67 using the MACE adaptor plate.

They mill out the adaptor so thats sorted you just need one vac line.
You may be able to drill one i to the side of the adaptor?

Bump on this 4 year old post.
But looking at doing ls1 throttle body onto my l67.
Do i just use the sensors that are on the ls1 throttle body
Tps and iac
Or do i fit the l67 ones to the ls1 throttle body ?

Have to use the LS 1's as they're both completely different & wont swap, but just plug & play from memory & then tune to suit!
