Everything you need to swap a k20a2 into an EP3

[WhiteOnRice]

I am copy and pasteing my thread from EPHatch so non-EPH members can get a write up. Please add it to the FAQ Todd On with the show: This is a list of things you need to swap a k20a2 into an EP3, motor up and out. No messing with the subframe. What I've gathered that isn't obvious or doesn't bolt in: -Replace RSX-S power steering pump with EP3 idler pulley -Serpentine belt: 64" 7-ribbed or EP3 belt (will be on the edge of spec but works fine). 64" 7-ribbed belt: http://www.autopartswarehouse.....html -RSX-S engine harness, EP3 can be used with modification for reverse lockout. -EP shifter may need to be cut to reach reverse ( http://images.sportcompactcarw...m.jpg ) I had to shave the piece that sticks out to the right (my ep is 2002). Had to disassemble and shave whole thing piece (it's about an inch tall from right above the arrow and up). -Use your ep shift linkage. -RSX-S ecu (use EP3 until you get your key reprogrammed to ECU by Acura/Honda, keep RPM's low until while using EP3 ECU) Costs 0.5 hours of Acura's time - $55 and some cents for me. -Use EP3 axles. -I used an EP3 DCRH. You'll need custom work if you want to use the rsx-s em/dp (I don't suggest modifying your exhaust this way). Let me know if I should add anything. How to retain A/C if pulling engine up and out: Yes, a k20 can be pulled up and out. a3 belt tension on a2: Oh, if you don't take a picture like this, your new motor will immediately throw a rod on startup: If anyone have a2 swap questions, ask them here please.

That mod never answered. Use the a2 alternator and you'll be good!
