Sir mangina, you can use the jdm accessories fine I did, The usdm ac line only has one bolt in it and needs a little bend to reach perfectly but mine sealed fine with only one bolt. Same with the P/S you just have to bend it a bit and make sure your threads match, if they don't, remove the adapter you'll find in the JDM pump and your usdm hose should now connect to it fine. Use the lower mile accessories if you get them , why wouldn't you right?
Edit added some pics.
Ac lines sealed fine!!
You do have to repin this connector, easy and obvious..
The clutch setup I currently run and recommend:
Stock newer version pressure plate
ACT 6 puck sprung or sprung full faced if your scared
mid-weight flywheel 11-12 lbs.
Stock disc material is old school tech, heats up and burns up too easily if you ask me. Plus this setup can be had for cheap, I did mine for under 300 with flywheel. You can use any clutch if you know how to properly shift. Im on the glass 5-speed and launch perfect all day.
