A series MG 1275 engine rotation
Does anyone know if the rotation of an A series MG Midget/Marina engine is the same as ford?
I ask as one idea i had was to use an A series 1275 engine and plop a turbo on it from an MG Metro. Not great power but i'm not after
performance.

Same as crossflow and pinto

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

most likely be same as B-sereis and that went clockwise when veiw standing in front.
in fact you cab bet all engines do this apart from some Honda ones.
BTW you may need to lower CR but A-series are quite low anyway, well, comapred to modern engines. new pistons, thicker head gasket, enlarge
combustion chamber

I have a friend who builds and services mini's so i'm sorted for turbo info!!
What's lowering the CR? Is that combustion ratio?

Compression ratio.
If you can get hold of them, the pistons from a Metro van gave a nice low CR for upping the boost. In it's stock form the turbo had a fairly
high CR (9.3:1 IIRC) and boost was limited to a measly 4PSI around the peak torque RPM increasing to 7PSI as the RPM increased. This was primarily to
save the gearbox from destruction, but running 7PSI on an unmodified engine also resulted in detonation. Mostly down to the lack of intercooler I
suspect.
The proper Metro turbo head has sodium cooled exhaust valves as the standard heads suffered from burnt valves.

adaptor
You wouldn't use a sh+++y bmc gearbox though would you!!!!!
You can get an adaptor for the type 9 Ford
Could be OK an 'A' series is not too heavy.
Didn't the standard Metro Turbo have about 90bhp?

Where or who does the type 9 adaptor?
I had a midget years ago and the gearbox was fine.

Sorry iank that a 5 speed conversion for the orig box, not a conversion to the ford type 9 which i thin is only available for the k series engine.

99% certain it's a type 9 to A series (or chocolate 1500cc Triumph engine). Not that it says that on the 5 speed page, but it does admit
it's a 'Ford 5 speed box' on the price list page. In the past they had a 5 speed toyota box but the donors ran out IIRC. A quick
google finds at least one reference to a 'sierra' 5-speed to 1500cc from Frontline.
Give them a call to confirm one way or another if you're in the market for one.

93bhp, 85lbft from the factory. They have been made to push out over 200bhp, but it's probably rather closer to a grenade than an engine by
that stage.
I have to say that I really like the A series. It's crude, rough and limited by the 5 port head, but still a great little engine considering it
first saw the light of day in the early fifties. And of course it was one of the original fitments to the Lotus 7.
