Whats up guys. I am looking at buying a usdm obd2 gsr swap for my civic and i had a few questions. 1. What ECU should i run.. i know the obd2b ecu has the immobilizer so i can't use that 2. What do i do about the exhaust as of right now i am running a WS2 cat-back 3. What mounts should i use..i am thinking about just opting up for hasport mounts 4. I know i can use my engine harness and most of it is plug and play but what would i have to cut and extend 5. What are my options in regards to the butterfly valves should i keep them or opt out for a skunk2 IM thanks guys for reading my post. I think that is all the questions i have for right now but i appreciate all the feed back i can get.
