I've got one and it should bolt straight up to a type 9 as its essentially a zetec. MT75 should be the same bolt on job as the type 9 as well.

The exhaust side bolt holes for my engine mounts are missing tho, but that shouldn't bother you startign from sctratch, its just they are different to the zetec.

A huge piece of the sump needs cutting off. Flywheel needs changing as the ST one has a weird floating centre.

Good news is it should have a spigot bearing already in the crank. Thats probably to support the floating bit of the flywheel.

I'm hunting for a (free) Mondeo box to make a bellhousing with that leaves the starter under the inlet and removes the need to butcher the sump.

And welcome to the forum, where in the world are you?

Cheers,
Steve

If you use a t9 think about the power you are putting thru it i would think a H/D t9 would be better or use the mt75. I thought the starter went on the exhaust side (right side if looking from front to back) although if you have a ST150 that is a Duratec engine.

Just seen this snippet of info on the totalkitcar website and it may be of use to someone out there

http://www.totalkitcar.com/home.php#1662

"SNIPPETS 2……So, you’ve got or are building a Ford Duratec HE four cylinder-powered kitcar and don’t find the Type 9 or MT75 gearbox particularly thrilling, especially for more potent applications. The answer? The Mazda 6-speed, as fitted to the current MX-5, bolts straight on and is well up to coping with 300bhp. It’s a relatively cheap option, too. Expect to pay around £700 from your local scrapster."

st170 out of ford focus

hi guy thanks for the threads but if im looking at the front of the engine the starter motor is on the inlet manifold side so the d9 nor the mt 75 box will fit the starter on because the motor is in the way the gearbox or coversion needs to be on the left near the top of the bell housing ps wheres the mazda 6 speed starter fit on the box

Focus ST170 is a Zetec not a Duratec even though its badged as such.

Standard type 9 bellhousing fits with mods to the ali section of the sump. Removing the ali around where the starter will fit is straightforward.

I've not done it yet but it has been done with Blacktops which is what the engine esentially is.
