Hi Richard,

By any chance have you run across pics of the exhaust side of the motor?

I'd like to see how the exhaust manifold is configured.

Thanks,
John

No, I would love to find a cross section of the ZY-FE though.... I will let you know if I do!

Very nice questions you have, I would love to see the answers!

Answers some of your questions...I can clean this up and get it stick-ied if dessirable...

If you need questions answered, PM me, and I'll see what I can do

^ Awesome! Thank you! And Yes, if you want to clean it up (or I can), I will edit the first post to reflect the new data so it can be permanent info on the forum! Thanks again!

Edit: Updated! Thank you again!

If there are format issues that you see, please let me know...

If you'd like to, go right ahead. I'm just here to provide information, you can make it look as "purdy" as you'd like Just make sure we get some credit! lol.

Thanks Guys,

Lovmyrx7, got any pics of the back of the engine so I can see the exhaust manifold configuration? Also, do the auto and manual transmissions have different ring and pinion gears with different ratios? If so, I wonder if they interchange?

Much appreciated,
John

Thanks!

Just stumbled across this info on gearboxes

http://www.protegefaq.net/transmission.html

there is multiple versions the F35M-R one with some good ratios.

2.059:1
1.392:1
0.970:1
0.795:1
FD 4.388:1

Does anybody have rod length, shaft & pin diameters?

rod length and pin from what?

u mean connecting rod?

since there are no push rods, i assumed that the con rods are the only rods in the engine.

Using keyword "Rod" @ Mazda EPC2

oh, yes, i'm definitely talking about PN 66-934.

I'll try to find it if nobody knows.

Quick question, is the U.S. 1.5 an interference engine? I know it shouldn't be an issue since it has a timing chain instead of a belt but I'm curious.

Click to expand...

My understanding is that it's more likely an engine is an interference if it *does* have a timing chain...if having the timing go off can cause your engine to blow up, you'd want to use the most reliable linkage possible.

It's a safe assumption that it is an interference engine. Just about any engine made these days will destroy valves if the cams are far enough off.

I'm curious about your curiosity.
