Im getting ready to this swap, im wondering if theres anything i should know as far fitment and compatibility issues. It seems like it will be real straight forward.

Im thinking the itr header will not bolt to my stock si exhaust because the itr collector is 2.5"...is this correct? If so can i temporarily use my b16a2 header until i can fab up an exhaust?

any other issues i may run into? are the ecu's interchangeable?

 

Im pretty sure the b16 header will bolt onto the itr block until you can fab up a 2.5" exhaust.

Anyone else got any insight? im gonna be helping him do this soon.

 

inspection issues...

 

can you elaborate

 

obviously you cant bolt on the b16 header to the itr block!!!! buddy you should becareful he doesn't know much about engine swaps! the b16 header fits the block but the oil pan will actually be in the way!! trust me learned it the hard way!! have fun with the swap though

 

Nice first post

It appears you are the one who "doesnt know much about engine swaps" because the manifold is on the motor, in the car right now.
