what do i have to change?? i am gettin engine for sick low price, and i wanna know if i could leave my gsr tranny and just change the ecu?

 

c5 is the same as gsr cept for internals, cams, head, manifold and TB.. everything should run fine, just run an itr ecu.. i was gonna wonder why you're swapping those motors until i saw that you're getting it for a sick price

 

You don't have to change anything. You can use any B-series tranny you want. It will be a straight swap.

 

Be sure that the seller is legit, and that the engine isn't stolen.

 

no not stolen.. never support the theives. just that my warrenty is buyin me used engine, and i told em i would pay the diff to get the c5, and sell my old head. so not thinkin it will cost to much
