Most likely it would be from Australia so the shipping cost alone would be a killer.



Back in the early eighties a buddy of mine working in mining exploration got sent by his employer, Teck, to Australia, but he said he'd go only if they shipped his MGB down there ( from Vancouver) and they did.

There is no separate bellhousing, it is integrated into the case half.

As much as I wanted to button it all up and be done
with it, I discovered the 5th/synchro retainer snap
ring was considerably worn. Would hate to do all
this work and have a $.30 cent part fail.

Be very careful using a 30 cent Chinese made snap ring in your transmission! Transmission snap rings are very specific in there size (thickness), hardness, and flatness. Cheap rings are not consistant thickness, and often have a large radius at the edge from being stamped in manufacture, and can be forced out of a groove with high axial force if the radius it facing outward, or if the ring thickness does not match the groove well.

You are absolutely correct.
This is a quality snap ring, made in U.S.A. and not of
the 'Harbor Freight Tools' quality. However upon closer
inspection, it is in fact a little off.
While it's probably a better fit than the worn snap ring,
I have found a better match, guess I'll have to be anal
about it and order them up, fortunately they have an outlet
close by so I don't have to wait for shipping.

Actually I'm already good at some of the stuff having done it so many times. I could replace Mk1 tie rod ends and balljoints with my eyes shut since I've done it so many times. It was mainly trying to fix the ECM electrical and now no start problem in the '88 carburettted Forsa I recently bought that I was finding to be a F'ing pain in the Ass. It's on the backburner now though because I just bought a 1998 Chevrolet Metro 4 Door Sedan with a 5 speed manual trans that runs like a top and I'm going to get one of my '88 Forsa turbos and my '94 Swift 4 door sedan back on the road before I get back on to fixing the '88 Forsa carburetted.

That's a far down the road project because I've got a pile of Sprints, Forsas, Fireflies, Swifts, Geos and Metros to get back running in stock configuration first, and I'd better get cracking on them before they all rust weld themselves into junk status, but I can use the time to plan it out and acquire the parts to turn one of my turbos into a super fast super good handling car.

Not a lot of updates here, spare time has been pretty sparse,
but I have managed to get a few things accomplished.

Polishing is almost done on the intake manifold, total PITA
I will probably not do this again as it is too labor intensive.

I did get some work done on the head and manifolds, got tired
of looking at them sit on the bench. I'm determined to get this
beast back together by the end of the month.

The head was fully ported prior to rebuilding. Now using the gasket
as a template, I've finished the port matching on both the intake
and exhaust side.

Image

The alignment pins were pretty much pickered, so I got some
thin wall hobby tubing and used a razor knife to slice off some
sections to make new ones, then chucked them in a drill to
bevel the edges. I probably saved a couple of grams each on
weight over the OE ones, so I know I'll be getting a better overall
power to weight ratio when finished. =)

Image

Perfectly matched intake side.

Image

Image

Exhaust side is done.

Image

And here's the underside view showing the new valves.
Stainless steel exhaust valves, and 2.5mm oversize intake valves.
This required some seat work at the machine shop.

Image

I'm cleaning up the cam gear backing plate which required hunting down some new grommets,
I'll be reusing the metal grommet inserts. Hand cut gaskets for the middle section of the throttle
body using gasket material, scissors, razor knife and a steady hand, as well as a handmade gasket
for the distributor mounting flange. Popped in a new temp sensor for the idiot light as well.

Image

Image

Image

Biggest accomplishment was dropping off my down tube and custom header for
ceramic powder coating, which should be ready next week.

Unfortunately I did have another setback, it seems the spark plugs on the head
I chose for rebuilding had been cross threaded. I never checked them when I pulled
the head out of my parts stash, and neither did the machine shop.
I discovered this when I went to index a new set of plugs and had difficulty
pulling them out. I ordered a spark plug thread chaser and hope there's enough
meat left to save. Fortunately I discovered this before mating the head to the
block, in case it requires a machine shop repair.

Slowly but surely coming back together. :mrgreen:

Some other minor updates, mostly tedious work,
stupid shit, and waiting for paint to dry stuff..

Various bits 'n pieces, coil bracket, fuel filter bracket,
brake line securing brackets and such.
Cleaned and/or wire wheeled and repainted.

Image

Cleaning up more of the engine bay while the transmission
is out. Previous battery acid damage did a number and I patched
things up best I could when it was running. Now that I have better
access I've got a chance for a more thorough cosmetic makeover.
Not high tech at all, just some light sanding and Rustoleum primer
and paint and the patience to let it dry properly between coats.

Image

Also got a chance to install the rebuilt alternator, OE alternator rewound to produce 100 amps.
Forget the GM alt upgrade, this is a piece of cake after my local guy hooked me up.
Unfortunately the magnesium pulleys for the MK2 did not work out, after mounting an MK2 water pump
and sizing up the crank, WP & Alt serpentine pulleys, they did not line up. Bummer, that would
have been cool having that ultralight setup, but just as happy to have the OE v-belt setup.

Image

I'm mating together a larger reservoir for the alcohol injection.
I took my modified water bottle and hacked off the bottom and mated it with an
aluminum tube that was a water filter housing. The fit is perfect, just gonna seal the
2 pieces together and I'll have enough reserve for an estimated 4-5 days of daily driving
without refilling. The bottom half aluminum should polish up nicely for some bling, and the
whole thing is slender enough to fit where the OE washer bottle was mounted and still
clear the strut tower brace.

Image

Nicely enough the spark plug chase showed up today, so I might get a chance
this evening to try to save threads. Not bad for a $10 Ebay buy, and got it in
about 2 days with just a click, it appeared like magic with no effort on my part.
Keeping my fingers crossed. :-|

I'm curious what that alt will put out at idle. Rewinding for more output hurts the low rpm charging and that's almost doubling the output. The regulator would need to have been changed too no?

Yes, the lowspeed output was low when they tested it,
but it had that funky large pulley on it I was gonna try so
I had attributed some of it to that. Typically full output
should be achieved @ 1200+ rpm.

I had almost forgotten about that. I do not know if they
changed the regulator. I'll report back on actual output
once it's back together and running.
