Zetec/gearbox/injection or webbers?
Okay, these are probably questions which have been asked a million times before, but anyway, help a newbie:
-How can you connect a Zetec (1.8-2.0) to Type 9 or MT75 gearbox? Does it just bolt on, or do you need a special bellhousing?
- Which box is prefered, and why?
- To save costs, it seems to me it's easy to use the existing EFI system, instead of mounting a pair of Webbers. But why do I see Zetec's with
Webbers everywhere? Why shouldn't I just use the fuel injection system supplied with the engine?
- BEC is also still an option, but since I also want to use the car to cruise around, I'm wondering how practical a BEC is. How's the noise,
compared to a "CEC"? And overall driveability? Isn't a BEC too "nervous" to use in traffic?
I'm looking forward to some help on this subject, so I can decide which way to go...

The bolt pattern on the MT75 is identical to the Zetec. If the Zetec was originally fit with a 5 speed then you are in business. The only challenge
is fitting the starter from the MT75 donor around the sump pan of the Zetec (requires some creative grinding, but that's all). The Ford Focus pan is
different (and a little more accomodating) than the Mondeo (Contour) pan. A new pan can be had from Raceline. It is exactly what the doctor ordered
for a high performance RWD configuration, but you're going to pay dearly (something like $500US... or maybe 500quid... I don't recall... a lot
either way).
I know that the pinto and zetec bolt patterns are identical... so if the T9 is sourced from an old Pinto 2L, then again you are in business (not as
easy in the States... bugger all). Again you might have to get creative with the big ole' sierra starter.
Birkin makes an excellent bellhousing for joining a T9 to a Zetec and it uses the original Zetec starter (smaller, lighter, high torque) in the
original location (out of the way of your feet).... It's a brilliant solution, but about $300US.
I highly recommend you source a Zetec that was originally fit with a 5 speed instead of trying to convert from an automatic. Otherwise you'll need a
manual flywheel, starter, and crank sensor bushing/housing as a minimum... not impossible... just more bits to buy.
I don't have direct experience with either box, but I know that the T9 is lighter than most and it is sufficient for all but a truly worked-over
Zetec. You might consider gearing ratios as well when making a choice.
I plan to use the stock fuel delivery system... my Zetec is from a Mondeo (contour). The intake manifold is a massive beast that will barely fit
under my custom chassis's bonnet.
In relatively stock form, this engine will put out 140 ponies... plenty for me... no need to go with the extra cost of webbers. I pulled all the
donor wiring and computer to go with it.... Maybe that's why a lot of people go with webbers... they didn't get all the accessories from the
start.
Not familiar with the term BEC and CEC... no opinion there. 
Cheers,

Note to all: I really don't know when to leave well alone. I tried to get clever with the mods, then when they gave me a lifeline to see the
error of my ways, I tried to incite more trouble via u2u. So now I'm banned, never to return again. They should have done it years ago!
