1993 mazda mx3 1.6L 16v to ‘90 ford festiva L swap

[Anoldfestiva]

I am currently negotiating a price to purchase a 93 mx3 that has a bad transmission. I may go see it tomorrow and decide to get a tow. Is the engine swap possible to do with this engine? Thank you. I am also looking for shops near Detroit, MI that do major repairs and engine swaps.

Paste this in the search bar (without the " "):
"B6-ME OR B6ME"

Physically the same as any B6 swap. But the electonics, Fuel Injection control systems, and ECU are what you have to worry about. They will not be identical, and you will need to search here to get info on what to do for the wiring.
It is a very feasible swap.

It is NOT physically the same as any B6 swap. Depending on how you mount the engine you may have to clearance the firewall a little to make room for the intake manifold. You will also have to relocate the VAF to the other side of the vehicle which usually means that you have to move the battery to the passenger side to make room. There is a little electrical stuff but it should be pretty easy.

I am a bit of a newb here but because of everyone Who had done engine swaps it inspired me to do one. Although I used a particular year car/engine with not a whole lot of info about, but without these guys I would have never done it.
I’ve just been working on this same kind of swap, Well almost the same, I used a 1994 mx3 1.6.
and like ice dawg said, The electronics and wiring are different then the festiva. And in the 94 mx3 the wiring was different enough.
Rather than wire tracing identifying And resplicing the festiva wiring harness. I found It easier to just remove the entire wiring harness “and install the mx3 harness, routing it where it would fit. Relocating the ecu. A little bit of shortening and lengthening of certain parts are necessary.
The only wire splicing involved was the rear lights/ fuel pump/heater blower motor and control/ Hazard light switch/rear defroster switch/ a few small things. I was also able to use the MX3 wiper/turn signal combo switch in place of the festiva one, and even the ignition key switch.

and also like firebush said I had to get a slightly smaller battery to fit it on the passenger side
no firewall cutouts were needed though, just positioned the motor as far forward as possible. And it would be way easier for you if you used the stock festiva E series 5 spd trans.
i didn’t though I had the Mazda 5spd manual f25 trans.
anyway good luck. Hope to hear something of it if you go for it

Did you need to weld the transmission cross-member for mounting?

Yes I did I had to cut off the rear angled type mount and bolt in its place a welded bracket, and weld in a riser for the front mount

most of what I’ve done is there, It’s just not up-to-date since my last post
