626 coilpack FS engine

[rarefc3s]

My 01 2.0L spun a bearing and is dead. I ordered an engine from a supplier who is in Canada (tigerjapanese.com or jdmtigerjapanese.com) and list the engine as such: FS engine, Mazda 626, 98+ coil pack.

How much of an issue am I going to run into putting this in a Protege. I figured worse case everything on my block and head will have to be swapped over. I don't think this is actually a 'JDM' engine rather it is likely a Canadian motor and pulled from a 626. Everything I can find says it should be the same as the Protege FS as far as compression ratio etc. If its the same block and head then I'm good to go minus wiring the coil packs which people do anyways to get rid of the crappy 'coil on plug' setup.

Anyone used one of these before?

Engine is here. Pretty damn clean too. I find one sensor that is busted I'll just use the one on my motor.

^^^ Possible issue here; a flex plate? Also notice white crud in the throttle body. The screws on the butterfly inside is a bit rusty too. I have an expensive aftermarket flywheel but what I don't know is is the manual and auto interchangeable without switching anything else (bell housing)?

thats a flexplate, but thats not an issue. flywheel will bolt right on. keep the intake manifold and use that one VS stock. swap valve covers and ignition. does that one have a cam sensor on it?

Is that the single runner 626 one? There is a large plastic box bolted to the back of it/under it.

I have your manifold on my car now and was going to use it or leave this one on if it is the same.

I was hoping to use this ignition. Looks about the same as the Miata coils people seem to like. I'll check for a cam sensor.

looks like the cam sensor on the 2nd pic from the bottom....unless i'm thinking it's something else

and yeah that's a single runner intake mani.....if you use his put that one up FS

Think you are right.

That was the plan sell one or the other. I'm loving this purchase so far. If it all works out I'll do a little write up with pictures and my progress.

and you can use that ignition i believe.....in fact a lot of pro guys mods for that ignition....or one like it

 

[bgibb68]

how much was that block? and how many miles on her??

 

[rarefc3s]

It looks exactly like the Miata coils.

$490 plus $180 shipping. 25-35k miles. The bonuses could be intake manifold and coils. That is why I bought it. I think if it works out I might start a fad, lol.

Have fun fitting it!

I just changed mine over this weekend.

I'd say that the hardest part is trying to re-connnect the gearbox back up, and lifting the 300kg(ish) back up into the engine bay!

 

[rarefc3s]

I'm just about ready to pull it finally. Haven't really worked hard to get it done. I'm left with draining the trans and pulling the axles. Should be ready to lift out after that.

 

[bgibb68]

that's a kick ass deal....someone in jersey just got the fsze(s'posedly) for like 550-600 with less than 60k.....i hope i can find a deal like that when it comes time.....i would much rather build up a block(with less milage) and do a swap plus i can keep my car running while i'm doing it and come out with a spare, just in case

The motor is in but I have not started it.

From the original Protege engine I had to swap the water temp sensor, the thermostat cover, fuel rail, and the oil sending unit. That is all. You could use the 626 fuel rail but you would need to run older style fuel lines (mine were some snap on 'quick connect' lines).

I did open up the wiring loom and pull the coil wiring out to reroute it. I left the coils on the front of the motor in the factory bracket and moved the wires to it instead of doing the opposite. I've seen the turbo guys move the coils to the passenger side and away from the turbo manifold. If I ever go turbo I think I could easily do that since I ran the wires in a separate loom.

Interesting to note that the 626 header does not have a pre-cat and appears to be a better design in that it is not a log. Its actually 4-2-1 it appears. I do have to take the car to a muffler shop to make about a 4-6 inch connection from the header to the exhaust pipe. While it is there they will have to put in another 02 bung. The 626 manifold does not have an 02 sensor in it.

If it starts and runs without issue I'm going to do 3 pulls on a dynojet to compare it to old engine.
