ok, i know that i'll have to do a dpfi to mpfi conversion, but will i need new knuckles like you do when you swap into an HF? is there anything else that i'll need, other than everything you need to swap into an Si? thanks

 

No you won't need the knuckles.

You may however need some new ones after the engine swap

Glad to see another person from Colorado postin

 

Only the HF knuckles are smaller.... what parts do you have?
