Hello, i have a 91 si and it already has a b16 on it. i was wondering how hard it would be and what i would have to do to get a gsr swap to go in it and work?

 

should be bolt in, plug and play...

 

i think i remember that some wiring will need to be done but not critical just making some wires longer etc. but its for the most part straight forward

 

Not exactly.....

Because of the weird *** manifold the gsr has, some wires will have to be extended, plus a wire will have to be added for the secondaries in the intake manifold.

By using either a new type r style manifold on the gsr, or swapping the head out from your b16a, the swap will be plug and play. Don't forget about a new ecu.

 

What ecu would be the best for this set up if i put my b16 head on it?
