i have an ls intake manifold off of a 94, but no throttle body. i purchased an SI throttle body, i was wondering if this is possible and if so, which throttle body gasket should i use for this?

si throttle body on an ls intake manifold...should i use the si throttle gasket or ls throttle gasket? confused on that part, it would be great to get the correct info cause that is all i need left in order to get my ls motor running. lmk thanks!

 

i would just go with the SI i think the LS TB is 60mm and a SI is 58mm but the the SI gasket should be fine

 

I would go with the gasket that matches the throttlebody. In this case: Si.

 

I know a 3rd opinion isnt really needed, but the two above are correct. The Si TB gasket would work the best.

 

that'll be the gasket that i'll be using then. thanks!
