Hello I am currently working on a turbo buildup project. I didn't have much luck at focaljet on getting information on the differences between the zetec pre focus. If anyone could tell me even the smallest details would be much appreciated. I just want to make sure I don't spend too much money and find out that I will not be able to use this motor. Also is the crankshaft the same as i'd like to stay stock in this matter as this motor may well be seeing 300 hp. Should I replace the maincaps?
The biggest differences are in the head and the windage tray/oil pan design. I have a set of main caps I think you might be interested in. PM me for details. The focus crank works, the rods and all that work, unless you're trying to use FSVT rods and pistons as I think they have an SVT specific design. I think you could use FSVT rods and pistons togehter (with some machine work to lower CR would be needed on the Head and pistons) on a stock focus crank and have a pretty decent setup capable of 300HP easily.
So are you tring to put a pre-98 Zetec into a Focus? Or are you trying to put a Focus motor in a Pre-98 Contour?

If you have the metal 00 mani port that Biznatch and get'er done!
hi, i put a focus M45 jackson racing supercharger kit on my 2.0 mondeo zetec silvertop (which is year 1994). the differences where the alternator, PAS pump and entire drivebelt route/pulleys is totally different setup, totally different engine mounts, sump/oilpan has the recess in different place, exhaust downpipe and cat totally different, IAC valve, throttle body and throttle cable all different. as is the traction control and cruise control units. cambelt is shorter on the silvertop.
also the fuel rail and injectors, fuel pressure regulator, MAF is 6-pin instead of 4pin (easy to convert though), then theres the internal differences like hydraulic tappets on the silvertop.
the cams and cam gears are interchangable, as is the inlet manifold but you may need to mod it around the alternator.
i can go into more detail if you need it just giz a shout.
I just posted this on the Foclajet Forums. Correct me if I'm wrong with anything...

The pistons, rods, and crank are the same. Similar coil packs and wires, but some models had clips on the wires, others didn't. The oil pan is a one piece design that is shallower on the accessory end, deeper on the transmission end (opposite of the Focus). The oil pan and pickup are totally different from the Focus. I've been told by Tom (focus-power) that the main caps are all the same. The heads vary.
Pre-98:
-Hydraulic lifters
-EGR (no VCT crap)
-single timing belt tensioner (won't work with Focus or FRPP head)
-centered water pump (won't work with Focus or FRPP head)
-4-wire MAF with seperate IAT
-different oil pump design than 98+
98+:
-mechanical lifters (same as Focus)
-VCT (no EGR, you can tell by the funky cam gear and the taller valvecover)
-Timing belt tensioner and idler (same as Focus)
-offset water pump (same as Focus)
-6-wire MAF with internal IAT (similar to Focus)
-same oil pump as Focus
In order to drop a Contour/Mystique/Cougar into your Focus, you would need to swap over the passenger side motor mount/timing cover piece. That would restrict you to 98+ Zetecs. Either that or you would have to swap your timing/accessory drive from your Focus onto the Pre-98 Zetec.
Also, it is probably a good idea to stay away from a 95 Contour/Mystique Zetec. They used OBD-1 and some other funky stuff. The motor is the same as the Pre-98 though.
Ford Contour, son of the Mondeo, father of the Focus. 
I hope this helps.
I do have one question though...with the large amount of Focus motors out there why go for a pre98 zetec? I could understand a new focus zetec in a pre98 but the other way around?
I think the Focus guy got a '96 Contour Zetec for cheap. Not exactly sure though.

I would, and I am on my turbo build-up. I wouldn't trust any of the stock cast pieces. I'm going with ARP main studs, ARP head studs, forged rods, billet main caps, and forged pistons. I'll probably also have the block o-ringed.
BTW, I see you bidding on that FRPP head. You suck. If I had the cash I'd be all over that.

I got the motor for 150 bucks pulled which was pretty cheap considering being handed a motor without worrying about shipping, etc.
I'm basically doing the same parts for the same reason as you BP. I'm hoping to land the head as it would very sweet to have.
You probably already know this but... Have a machine shop check it out to make sure that nothing bad happened to it. You'll probably want to have it hot tanked/boiled to get off all of the old crud anyway.
I was lucky enough to get a new '96 Zetec for the same price.
That's going to be my turbo motor. (I actually bought it for $500 but sold $350 worth of parts that I didn't need.)
Have you taken the oil pan off of your '96 Zetec yet? I'm hoping that there's oil squirters for the pistons. I heard that they got rid of them on the later model Focus Zetecs.
BP
Mmm just checked the motor and I believe it does not have oil squirters. How big of a hurdle is this going to be? Should I just sell what I have and go buy another motor? How would I be able to tell if the motor has them?
btw BP you have a pm in focaljet
I didn't know any zetec had oil squirters. But anyways, I don't think it's that big of a deal. In fact, I saw a high hp dsm engine with the oil squirters removed for some reason.
Actually your right Kremit. I somehow forgot that the newer zetez does not have oil squirters, why I don't know but I don't believe they are really needed from what I hear. The svt foci do have them tho and there are cgi WRC blocks that have the option of having them.
It's really not a hurdle. It just would have been nice for added insurance against detonation.
I thought from reading Mad Mole's Mondeo Madness that the Pre-98's had oil squirters. Maybe it was just the older CVH style engines.
