All 01+ motors have vtcs msm or vvt. Only the 99-00 has vics.

Similar enough to say yes, but enough parts and part numbers different to be able to argue either side. But for sure it has the silly vtcs, and not the cool vics.

Msm is 99-00 block and head, '99-00 valve cover but with vvt coil mounts, vvt intake, and a few other differences. Major bastard child that's made even awesomer with an 99-00 valve cover, vics intake, and a turbo upgrade.

block is different cause it has proper oil feed port. head has different cam in it, so kinda different. Bunch of people mentioned several things different over the years, like bearings and such ( think it was Ben that mentioned it last) but I don't remember the specifics. oil pan is different too, obviously. just little things.

mazda really likes to mix-n-match stuff

Thats cool, wreck more cars so you can send more of them over here and drive the cost down.

Why would you put a 99 valve cover on an msm engine? Arent the 01+ coils supposed to be the best coils that came on the miata?

Hm, I'd heard the opposite, that they were weaker than the 99-00 coils (although perhaps less likely to randomly die).

One benefit to the 99 valve cover is that you can use the TSE bracket for Toyota COPs.

The 99-00 coils are a common failure. NB2 coils dont seem to have this problem.

You are all missing the point of swapping over. It is all about looks, you are running LS coils anyways.

Yeah, you missed the point. You can mill down the "COP" bosses, and bore out the spark plug holes. Or throw on a '99-00 valve cover. The point is definitely LS coils, NOT the shittyest of the shitty '99-00 coils.

my point was that there's less of a reason to run ls coils if you already have 01+ coils.

For boosted and/or high RPM, I disagree. LSx coils are really good for OE coils. Nothing that came OE on the Miata is really good. *

Maybe one day I'll show you guys my black powdercoated MSM valve cover on my BP4W with LS2 coils. Oh the horror.

*The 90-93 coils are ok if you put a better igniter in front of them.

Dude that's a flash from the past, but I seem to recall that the MSM engine has the updated larger thrust bearing, where the BP4W has the (potentially) failaids thrust bearing.
