I have experience with this, I swapped out my auto to a 5spd in my 91 prelude. And if you're getting a JDM H22, the engine code is H22A, not H22A1. Any number after the second letter tells you that it is not JDM.These are some things that you will need...Jack with jackstands...you'll need to figure out if you're gonna remove the auto tranny from above or below the car, so you might want a cherry picker as well. The auto tranny weighs a hell of alot more than the 5spd5spd tranny w/startershift cable linkages shifter master cylinderslave cylinderlower clutch lineclutch pressure regulatorclutch pedal settranny mounts...you would need a rear 5spd tranny mount as the autos dont have one.shifter cable bracketclutch, pressure plate, throw out bearing.flywheel w/flywheel boltsYou might need a 5spd halfshaft (intermediate shaft) but i'm not sure with your generation lude...you will also need a new lower radiator hose, they are different lengths. You need to relocate the battery ground wire, and get a new heater core return hose.I also had to drill through the frame, because the auto tranny mounts differently than the 5spd. It's not a big deal, the location of where you need to drill is right next to the auto holes. You will need 4 grade 8 bolts and nuts.In order to get the pedals in, you will need to unbolt the steering shaft and drop it down from the dash....idk if im forgetting something....You'll need lots of time and patience, you should do a lot of research before doing this swap. Good luck!
