MG T-Bar Quiz

Half right Paul.

8G is an A-Series Gold Seal/Silver Seal (reconditioned) engine
84G is a B-Series Gold Seal/Silver Seal engine

So the codes would denote a "Gold Seal" or "Silver Seal" reconditioned engine had been fitted

Also half right CJ, my names Lee :lol:

although i'm sure you're right, this is what I found:

1956 to 1970 'A', 'B', and 'C' Series engine Prefix

The 'BP' prefix was dropped once BMC had its three engine types, A, B, and C. Again, there is a prefix, consisting of a number, then letter/letter/letter, then the engine number.

but then it does make reference to the 8G furhter down the page. :broon:

pants, i think i just missed some irony :slapme:

Correct the reference is to the Gold Seal replacement engines. However, although the source I was looking at says 84G and in fact 86G for the C Series, I seem to recall 48G also being mentioned by other MGB owners. My source is Neil Cairns' guide. The B Series in factory numbering would have been 18G for the MGB starting with 18GA going to 18GK and then 18V.

Needless to say though , next question please! I guess in fairness cj was closer but fight amongst yourselves as to who sets the next question.

you go for it CJ, i'll have a stab at the next one :broon:

When launched in 1985, the MG Montego Turbo was a very conventional car in pretty much every way.

However one aspect was unusual and that was down to the French.

What was it?

was it the talking dashboard? i knew about it, but had to google who came up with the idea, and found out some interesting things that i didn't know. the talking dash was first utilised by the french on the renault 11, some two months before MG did. also that nicolette Mackenzie did the voice :broon:

any good?

Nope.

The Monty Turbo had analogue instruments.

The first MG Maestros and a very few MG Montego EFis had solid state instruments.

It was something far more fundamental. Also some Metros had something similar but provided by a British manufacturer.

hmmmmmmm. *shuffles off with head down muttering under his breath*

Well, if you overlook the use of a turbocharger, which wasn't particularly conventional on a family saloon, I presume you are referring to the use of metric wheels?

I am indeed.

Turbos weren't very conventional, but were not unheard of by '85. The SAAB 99 turbo having been introduced in 1972!

But in a family saloon, the Michelin TDX system was very unusual, as was the fact it was a metric size, 365mm diameter wheels which is 14.37"

The Michelin TDX system was also unusual in that it had 2 grooves on the rim and the bead sat between the grooves and the edge of the rim. The idea was that the tyre could totally deflate/blowout (the TD part of TDX) but the tyre remain on the rim for long enough to bring the car to a controlled stop at the side of the road. Needless to say I never tested it. The only issue was tyre availability. With it being such an unusual size, the fact only Michelin made them, and that Montego Turbos weren't over common, finding them was hard, and when you did they were very expensive. About £140 per tyre in 1989! It explains why MGF wheels find there way onto Maestros and Montegos.

A similar system was fitted to the Metro but the tyres for that were made by Dunlop

damn! i found the bit about the 'run flat' tyres, but never twigged they were michelin :slapme:

nice one MGmad :broon:
