Internal External Swap

As to Ace's post minding the H23a H22a swap. I still can't figure this out. First Is it a manditory change to swap in the ex. coil? Second If so on a 93 si usdm - jdm vtec there is no plug in. I read that you have to open up the distibutor.

Steps till swap completion:
Ecu Wiring :thumbsup:
Header and Downpipe installation :banghead:
External/Internal Coil work :banghead:

You only need to open the distributor only if it's an Accord to JDM h22a swap. When I first did mine, I was confused about what people were saying on the net too.

You want to be using the h23a's distributor and external coil to make things easy. Your car is already prewired for the external coil, so use it. Doing so, you do not have to open up the dizzy because everything is a direct plug in. If you decide to use the JDM harness and internal coil, then you have to open the distributor and rewire to convert to external ignition.

Good luck man, it feels REALLY good to have your car pop into VTEC for the first time :wink: (although you should probably keep from getting up there until the break-in period is over)

Why is there a break-in period for a used engine?

despite it being used, it's most likely been sitting there for a while. meaning, stuff starts to settle, sediments start to form.

you're gonna want to clear your motor of all this junk before you push it really hard. hence the need of a "break in period".

Ahh.. I usually clear shit out by running it hard.. gets all the fluids moving.

I would probably flush my coolant and most other vital parts of my engine before I installed it though..
