Not sure if this helps or not, but this thread is from a chap on RHOCaR who fitted the same engine in to a RH 2B.  The 2B is a bit more agricultural than a Westie but there may be some useful links to parts etc. and he may have had to overcome some of the issues you may come up against.

A socially distanced pass 

Well after 8 months with no westy in the garage I'm now the proud (Well ish) owner of  a lot of parts that may well, one day, end up drivable  A cheeky eBay bid later (not expecting to win mind) a

Not sure it would make much difference. The pwm bosch valve has very small increments of movement. A 1 percentage point of movement is almost impossible to see by eye.   Got back on to inter

There’s a link to his pictures on there but the YouTube videos are no longer available unfortunatly. I remember seeing this at the time and was impressed.

Looking forward to seeing your build progress Steve, I imagine it could become a blueprint for others to follow!

Oopps, sorry, not sure why the link didn't work, but it may be that I was signed in to the RHOCaR site.

At least you have a working link now.  I hope it helps.

Yes thanks I had a good look through it last night.

So today i cracked on with getting some mounts made. Good old cad.

Rough cut out of steel plate. Even managed to pick up the holes ok.

20180606_131114-2016x1512.thumb.jpg.b08f0a79b583c76596be69dff248dfd4.jpg

For the odd angled hole I cut a hole then cut a piece of spacer tube and bolted in place.

Then welded into place. So the bolt goes in at the correct angle. Having second thought about the sensor I thought I'd cover all bases and add access. If nowt else it'll lighten it a bit.

So the idea of the enlarged plate is to incorporate an alternator mount. And it'll sit somewhere here20180606_140117-1512x2016.thumb.jpg.cad8793c55f191cd689791a8d5b9da7c.jpg

I've never actually had the pleasure of mocking up an alternator and have a couple of questions. 1. Is it ok to run directly from crank to alt pulley with no other pulleys? Obviously I'll need a tensioner at the alt. I'm planning on an electric water pump so no other pulleys.

2. I've not done the calcs yet to see if this pulley is ok size wise. But if it is are there any issues using a 4 rib belt on a 5 rib crank pulley?

Got the gearbox mount added as the mx5 mounts way further back vs the mt75. 

Then after checking a few dimensions here and there got the nearside mount started. Some discs made and nut welded on

Then assembled the HD rubber mount and tacked the nearside up

The off side is a breeze in comparison look at all the pick ups!

Then the swimming lesson run cut short my play time before I could tack up this side.

Another question. Are they there any implications of having the engine mounts offset slightly? There's may be 4" difference on the left and right sides?

Spot on mate, thats fine. As for the alternator running direct off the engine, its what @IanK (Bagpuss) has done with his with his tiny alternator. Worth looking how his is done as he is running an electric water pump.

As for the pulley belt, should be fine, just make sure they line up across the grooves. The grooves are the same width.

Not sure what rubber mounts you have for the gbox (if any) but the ones supplied with the mx5 SDV kit are too soft

I went for the uprated RS ones as recommended by a few of the SDV'ers. They seem pretty solid.

Narrower belt on the crank pulley should be fine. I think I've seen engines with two different belt systems running off a wide crank pulley!

About the offset, what will the torque reaction do? Thinking out loud, with the left mount further forward, I guess the rear left corner is going to try and move (up or down depending on the crank direction), which wouldn't be the case with aligned mounts. So it may eventually end up putting some extra load through the gearbox mountings. It would be better if it tries to push that corner down, which way does it turn?

Nice work on the mounts :)

The piece of tube is a great idea!

Got the drivers side mount tacked today.

Lower alternator mount made. I've made up some small gussets to reinforce once I do the final welding.

I had thought I could see a pathway between the mount and the headers for the steering column wirhout modification but no joy so need to have a measure up to see a way through.

I'll then be able to remove everything and refine things as all the mounts and stuff look a bit agricultural at present.

The torque was what was concerning me. However I looked a bit closer at the oe mounts and they aren't bang on either. Granted not as off as mine. But I've gone steel vs alloy and my mount rubbers on both engine and box are uprated hd ones and much stiffer than oe, so I think should be ok. It's going to have to be a suck it and see approach.

You could always add a high level torque reaction bar if it’s a concern or if it moves about too much.

 

forgot to say, I’ve been using plenty of CAD on my project too, although being the hi-tech sophisticated sort that I am, I’m using recycled cornflake packets. :)
