External coil conversion - Honda Prelude Forum

What is up? Can anyone give me a clue how to convert my H22 internal coil to an aftermarket high energy external coil? Going to go forced inducton and want to upgrade the ignition system as well. Any help would be greatly appreciated.

All I can think of is to use a H23A distributor...

You can use the jdm distributor. All you have to do is remove the internal COIL, there are 2 wire connected to the COIL. The one with 2 connectors you keep and just tie the extra connector off. Make sure its not grounding out or you will fry your distrib.(I learnt that the hard way) Remove the second wire. If your carefull you can take a wire from an extra harness and use the same crimp connector. You need to connect that wire to the open connector, punch a hole in the rubber seal, and wire it into the open spot on the wire harness. Connect the extrenal coil and a external coil cap to the distrib and your set.

hey i saw this an article of honda tunning.....so from the mag im reading you'll need:
(1) msd power tower, (1) tube oo epoxy, 5/32 and 3/8 inch drill bits :hacksaw or bench grinder (1)distributor cap Drill and an old feeler gauge

ok first locate the contactor inside the coil, take the 5/32 and drill it out, if the aluminum collar pops out just pop it back in.
(2)Turn the cap over and the the 3/8 inch drill and drill only about 1/4inch into the cap, this is only so you can recess the power tower.
(3)insert the power tower from inside of the cap, and they cut some of the tower off for being to long
(4)turn over the cap insert the red insulator, than the brass terminal nut.
(5)mix the epoxy in an old tray or something, than by using the feeler gauge pour the epoxy on the inside of the cap of the hole oyu made.
(6)now your done in 20-30mins...

thats what honda tunning said it was last months mag, it has the silver 95 prelude on the cover thats the only reason i bought it.
