Supercoupe Belt System + 4.2 Stroker Worklog

[DMX]

[history]

Got tired of of tracking down 112.5" belts and waiting for shipping as they're never in stock, got tired of fighting belt slip and the last straw was of course the "custom" crank pulley that no one wanted to build (for less than $600)


1999 Windstar Engine being built up on the stand - 3,028 miles ~6/2006

Just picked up a jackshaft, the tensioners, crank pulley and waterpump pulley from a supercoupe (already have the alt and ac)

[/history]

Its time to find a way to mount the jackshaft,crank and accessories from the supercoupe. This will give me access to sc aftermarket parts to over/underdrive by any ratio I want.... without hunting for a custom made [xxxxx] again.


More of a status update than anything but there is a question here though...


The supercoupe waterpump I picked up doesn't quite line up on the windstar timing cover, it does however bolt right up to the 95 Taurus timing cover.

It would have been nice to use everything from the new engine but is it really so bad to reuse the taurus timing cover? Besides the oil pump there really isn't anything that "wears out" after 100,000 miles is there?

Also, with the jackshaft in place there doesn't appear to be room for the distributor so for now I stabbed the cam sensor back in, obviously i'll have to make a bracket for the tensioner. No such thing as a slim/low profile dist for the 3.8 is there??

Thoughts ?

First of all.... welcome back!

Your the expert, but use the front cover. The only things to wear out are the front crank seal and any side seals / gaskets.

If the jackshaft fits the SuperCoupe, how does the distributor fit in that?

[rudedog]

Yeah, you're the man on this 3.8 stuff. The only other thing I could add to Luke's comment is that sometimes the front cover will corrode at the water jacket locations. Thus causing leaks and becoming unusable.


Is this still your gen2??? Will you be able to use the cam synchro, because I've got an 07 engine from a Taurus that I'd love to use all the EDIS components in my gen2.

I'm no expert I just love tinkering with my


On the supercoupe they use the distributorless system, perhaps because of the same clearance issues i'm seeing now, i'll attach a few of the engine bay pictures i've been looking over to see my options.

I was a little reluctant to give up the windstar cover since they alreay have the crank reluctor sensor(?) for that 36-1 tooth wheel. If you remember I love tinkering with electronics too and I wanted to assemble a megasquirt system some time in the future. From what I understand you just need that crank sensor, edis-6 controller and coil pack - the megasquirt system will interface with it. There are SAW and SPOUT signals for the edis and distributor systems respectively but unfortunately they are incompatible.

For the brackets I see that they run the ac on the opposite side, i'd like to run the ps pump there instead as it will be a hell of a lot easier to bend and route steering lines instead of those huge ac lines.

I hope the pictures clarify things a bit, just bouncing some ideas around since it literally dropped 30 degrees in 5 hours ---- too cold to work out there now

does the SuperCoupe use a cam position sensor like the later Vulcans in place of a distributor? I wonder if you could use one as a spark trigger for a MSD ignition setup.

BTW - Rudy... I was going to suggest the same thing to you for the '07 engine.

I believe we swaped everything over from the SC including the timing cover.

Got a little more done today

I think i'm going to mount the alt on the upper left bracket where the supercoupe guys mount their ac. I'm my opinion its 1000x easier to relocate a power wire+pigtail than either ac or ps lines. We'll see if that works out though.

I mocked up some of the brackets to check alignment, it looks like i can just flip the upper left tensioner something like this......

That should eliminate the need for all that thickness where it originally mounted -- hopefully enough to clear the distributor.

Also the timing covers were 99.9% the same, there's a slight thickness that required a long stud in the block for the windstar timing cover, no big deal just undo it and place a 30mm bolt in its place. (Windstar tc has the yellow oil filter attached)

The Last shots help to show the three belt tracks, crank1 to jackshaft1, jackshaft2 to blower, crank2 to accessories.

Thats enough for one night, i'll post more updates if I get out again tomorrow.

[DMX]

Not too much done out there yesterday, I've made up my mind that one way or the other i'm going to get the alt mounted on that upper left ac bracket area

As far as the ac itself I just took some rough measurements to make some kind of offset bracket - basically to extend it since it is tied in with the front motor mount. It looks like a 2" offset would line it up perfectly with the crank2 pulley.

so many belts and pullies

I love your supercharged taurus.
