Well first off.. the Miata is RWD and your MX-3 is of course FWD.. so this little gem of an issue will create all kinds of little problems you will have to research and solve. Cams & distributor location might be an issue, the oil pan will likely be different as well as the oil sump tube, a 99 car will definately be OBDII so you would likely have to swap out all the sensors, assuming that you can locate OBDI sensors that will fit. This is stuff just off the top of my head.. there could be LOTS of other issues.. my advice is to start reading the 4Cyl FAQ forum.. there is a TON of information in there about what 4 cyl engines are compatible with your MX-3. Cheers

Yeah I know it's RWD... that's why I was asking if my tranny would bolt up?

With the OBDII I was thinking of bypassing that problem by just taking all the wires and the ECU with the engine?... does that compute?

I've read the 4CYL FAQ's over and over... and all I can find that is helpful is that one that I got them to put in there.

I'm just wondering if anyone is more knowledgable on this subject than I, cause my reading resources are not turning up answers... or if someone could point me in the direction of answers.

Did you see this write up that Gro did?

He went into pretty decent detail.. granted it doesnt cover engines as new as 99.. but I found it helpful.

Yeah I read that one, but like you said it doesn't go into anything over 1997...

I would just walk into your local mazda dealership and ask one of the mechanics in the back if they think it would be possible, and what kind of problems would ya run into. I have always found mazda dealerships to be top notch and even help ya out if your just asking questions.


Then come back and tell us what ya learned

It won't work...

Lol... anything is possible.

I think the only complications would be a tranny.

You will have many more than that. My question is why? A good ol' fwd 1.8 BP will work for less money.

Why?... cause I always want to be different... but I guess you're right... I just like the fact that it goes away from hydraulic lifters to solid ones, and the VVT.

I think we all have are own preferences. You can still use the solid lifters in your engine and you would also need the right shims to go with them. VVT is just another high dollar techno gadget that really does little for you. If something breaks, it gets expensive....

I've always liked the simple OBD I stuff. You can slap a turbo on it, electronics are realitivley easy to work with, swaps are easy, and parts are cheaper...

If I had the money, I would go for a brand new spanking engine and have everything else replaced that would need to go with the new motor.

But I dont

So its just a stock 1.6 DOHC for me

Still pretty good though.

The bottom end of an engine from a miata will not fit into a FWD chassis unless you also have a FWD BP for donor parts to swap over to the newer Miata block.
