Im about to get a Skunk2 IM for my GSR with I/H/E, I was wondering if i should go with a aftermarket throttle body right now or keep the GSR throttle body on the skunk2 manifold?. If i should get another throttle body what size should i get?, and also what size is the STOCK GSR throttle body?.

 

if you go w/the gsr TB you're not gonna be able to use a strut bar b/c of where the throttle cable bracket sits. other than that the stock gsr TB should be fine, if you want take a dremel to it a bore it out slightly. i ended up going w/a jdm b16 TB w/a typeR throttlecable bracket
