is it possible to take a mx-3 v6 engine and 5spd transmission into a 94 protege?

Anything is possible. Sounds like you need some more research.

If you search you should find your answers. Short answer is yes. You'll need to find a donor MX3 V6 in the junkyard though to scavenge quite a few parts off. Off the top of my head, I think you need of course a KL engine, engine computer, airflow sensor, and transmission. MX3 axles, crossmember, engine mounts, axles, and engine wiring harness. I'm sure I'm missing something in there. Do a search.

Wouldn't it be better to ask the Protege guys about the swap?

Yes it fits, it's a bolt in swap. Lakersfan1 put it in a nutshell.

You can use 4 different V6 transmissions. The MX3 GS and Probe GT both have the same gearing (shorter), while the MX6 and 626 share the same gearing (taller)

I'm in the middle of this project now.

Ok so it starts on page three, but it has some good info.
Ive completed the v6 into a protege swap, but gone about it
a little differenly.

How Ever, you need to check that the protege chassis is a BG
as 94 was a swap over year for mazda and you need a BG chassis
to fit the MX3 running gear.

Ive used the front and rear running gear from a mx3 as its wider
than a 323 ( as its known down here )

Ive used a standalone ecu setup, so i have no idea over wiring loom
issues.

Since yours is LHD you have no issues with the master cylinder.
Me ive got a damm v6 smack in the way! (RHD)

Headers are a tight! and i mean tight issue, im currently running the
stock logs and they seem to be ok, the radiator can be moved forward
into the valance area for more clearance.

Other than that and mine is a two door hatch, power to wieght is
WOOHOO! though you need to have soild mounts and decent suspenion.

Since the BTP is a cast iron block and all the bits hanging off it
its not very light to start with anyway.

the stock springs gave what i would call a nice stance, but way
to soft for the racing im doing, so yea

put a corn cob in ya bug hole.

Do you know this for a fact??? The last time I checked the weights of the KL and a BP were nearly identical with in a few pounds. Even looking at them on paper it is pretty easy to see. The BP is an old school cast iron block and the KL is a open deck thin wall aluminum casting. In addition a BP-T has the additional weight of the Turbo hanging off the engine and IC that is ahead of the front suspension line this has the disadvanage of shifting the weight bias of the car for forward rather than maintaining the same front to rear weight bias. Even if the engines were the same weight just the fact that you have an additional 30-35lb of that weight hanging that far forward of the suspension it actually increase the weight over the front wheels by more that just that 30-35lbs.

BTW in talking to various people at Mazda over the years, it seems that Mazda cold weather beta test the K8 in a BG Protege in northern Canada back in '90 before releasing the MX-3/ MX-6/ 626 on to the north american market.

Not that it's a biggy, and I didn't even notice the previous few times when visiting this thread that the title reads "MX6 V6", yet all of the discussion is MX3 V6. No matter, the reason I was a bit concerned was that I'm guessing that there may be a problem using the MX6/626/PGT IM with regards to clearances near the brake master cylinder. Just throwing that out there.

I've seen a Protege in Toronto with the MX3 V6 in it. He got his Protege J-Spec bumper shipped in the same box as my MX3 J-Spec bumper. Haven't seen him around the boards in a long time.

so i found this website http://www.jdmracingmotors.com/index.ph ... rand=mazda
For price factors i was thinking about putting the JDMKFZE 2.0L V6 in. The one that is $595 cdn. its about 700-750 by the time it gets to me in Halifax. so you guys are saying it will fit? and yes i know JS i put that accidently and juts didnt bother to fix it. tell me what you guys think

If you are going to go that route - K series engine into a Protege, why not go witha big boy. If a K8 fits and has "X" amount of HP, and the KFZE will also fit and has a bit more HP than the K8, then the KLZE will also fit and it has the highest HP rating. The KLZE is going to be a bit more $$, but the significant HP gained for the $ spent on the engine difference cannot be achieved any cheaper through add ons onto the KFZE or K8. Best HP per $$ spent by far. If you're a real HP freak, there's also S/C or Turbo posibilities down the road.

Your a better man than me to fit a turbo V6 into a progete, it would
be the qiuze from hell! check the link in my previous post.

Im not at home at the moment so i can't run the tape over stuff
but the camside engine mount to firewall in a BG is 100mm less
than a mx3, and the over all engine bay is a lot shorter.

As for hp watch and wait. go the 2.7!
