Yes indeed. I've worked on a few of those. Explorer girdle is better than the dry sump one but still not perfect. The 24v engine is a bit of a squib imo.

Don't have a better pic of it, but this is the dry-sump pan:

 

 

you can only see two of them, but the mains were bolted down with ling studs that then were tied though the sump pan to pin them together (relatively) than then to the block surround.

 

this helped eliminate the twisting moment of the mains as the crank oscillated, they were a right PITA to line up, but done right, I never had a crank or block fail (plenty of others did).

 

Engines a bit of a dog, the blocks are ship anchor material, some 170Kg's for a bare block and almost no real good points, heads were a cut-down Cosworth YB, just adapted to fit, clearly done to a budget else they would have junked the block and started again.

 

even with increasing the stroke/bore and using slide-plate throttles etc, they struggled to make ~320-330Hp and were as lethargic as an elephant.

 

Still, the ProSport was an interesting car, could match running pace with the Moslers of the day (2007 Britcar 24), with 140L of fuel onboard.

Yeah, I've seen a few of those, it's a similar system in the explorer sump pan.  You can bodge the heads onto the 4L explorer engine which seems to work OK although the timing chain is a ballache! You can just about make out the sleeve bolts here:

considering the volumes, etc. makes you wonder why they did not just design another block/engine that persist in designing stuff to bodge round the fundamentals.

 

I guess Ford have not actually designed a new engine for what? 40+ years, the current ones are Mazda derived.

[FLD]

From what I heard there was some dissagreement with this one.  Ford put a very tight budget on it which is why it ended up with the oil drain for the head being external and the woeful timing chain set up.  The revised 2-chain set up was only released after pressure from ford os cosworth weren't happy with it.  From my experience the single duplex chain stretches whilst the twing single chains snap.

 

I was always a fan of older ford stuff but since being involved with LSx and later GM stuff they really have been left behind.

[Scuffers]

interestingly, I always ran the single duplex chain, yes it stretched, but once it had done so, they tended to stay pretty consistent. it was a dam site safer than the twin chain disaster! I can't see anybody actually snapping a single chain?

 

For me, it was easy enough to adjust with 4 vernier pulley's, without that, I can see it being a right PITA.

Yeah, I never saw a single chain snap but at over 2m long the stretch is quite significant.  I always swapped them.  I have seem some interesting variations for the cam timing though.  The OEM setup is a dimpled washer that locates the sprocket.  I've seen people sand the old one off and re-stamp the dimple; I've seen it drilled out and off-set dowels used; etc.  Verniers is by far the easiest way of doing it.

not sure where this thread went... but carry on

Sorry ed, VNT / VGT gets my vote

Today's random question.... Does the lsj/z22se supercharger manifold fit the b207 head? Cheers Ed Edit... Here would suggest 'yes' http://z22se.co.uk/t...nd-z22se.24657/

[leevx2.2]

Yes same head as z22 and lsj just different casting

[Doctor Ed]

With a few extra benefits...

[Bargi]

Yes. B207 head on z22se block is common mod.

[Exmantaa]

Actually, the supercharger manifold is designed  for the (US version of the) B207 head... It happens to also fit onto the Z22SE head, a slight modification.

(LSJ = B207 with ab SC instead of turbo)

[Doctor Ed]

Thanks. It's never clear (simply fishing the Internet) whether small things change in generations resulting is slightly different bolt patterns etc. Im completely new to this engine family... There's a lot to figure out/understand, complicated by the fact it appears under various manufacturers who I know exactly zero about

Have a look for the build book. There's a few versions which do change as experience was gained. It's downloadable
