Can you interchange(swap)hitachi and tec dizzys
I have a 96 honda civic OBD2 after a lot of consideration i'm pretty sure my coil in my dizzy is bad. I need to know if I can replace my hitachi dizzy with a TEC one without any modification with ease. Please let me know thanks.

any tech dizzy with internal coil will interchange coils to any other tech dizzy, whether civic or accord or whatever.

thericepatch, you are almost right. The 88-91 Civic had a little differently shaped coil with the post coming out the center instead of off to the side.
If you go to a wrecker for a coil, grab the ICM also. Commonly if the coil goes, it takes the ICM out with it. Try to avoid the no-name ICMs at least, Hitachi and NEC are OEM brands and are the best. Replacing your plugs and wires on time will protect your coil and ICM. If you have too wide a gap and too much resistance, it will overheat the ICM and coil, making them go out. Putting a little thermal compound, like you use for the cooler on a computer processor, on the back of the ICM where it attaches to the metal plate will help suck the heat away and prolong it's life. A little tube will last you a long time. I got a syringe of Arctic Silver 5 years ago and built 3 computers, did a couple ICM swaps, various other things, and still have a bunch.

HXs came with a Hitachi distributor, I'm really not sure why. We didn't get HXs in Canada so I've never really had an opportunity to look into it.

Re: Can you interchange(swap)hitachi and tec dizzys
Thanks for the info, FanBoy. I am not as sure on the specifics of d series tec vs hitachi, but I would think it would be the same as the swap I just did on an F22B. The 92-97 (maybe more, but those I'm pretty certain) tec has three sensors in it: TDC, CYP, and CKP. The Hitachi only has the CYP, the others are on the crank. I got a JDM swap that has no crank sensor and put it in a 96 accord EX that came factory with Hitachi dizzy and crank mounted sensors, so I swapped in a tec dizzy (which required some wiring/splicing) and ran the wires for the other two sensors to the ecu and shazam I got a running motor without the expense of sensors, crank gears, and oil pump. So to answer the initial question as fully as possible, yes you can swap a tec dizzy in the place of a hitachi and only use one sensor, but the reverse is not really feasible.

Would a 95 Accord EX have a hitachi dizzy? I've been trying to find the difference between the two because mine is leaking pretty bad. Sorry, though, I can't say anything useful to the thread.
