Turbo Mini Forums

I'm thinkin of buyin an mg turbo engine of a guy .The thing is it's already been tear down and im buying it as parts.

Could please help in what things to look out 4? Especially since I don't know if the that took it to bits guy has any mechanical skills

It's a mini thing you will not understand

look at wear on the bearings, crank journals and cylinder bores. Thats all i can think of, i am sure the other guys will advise you more

As above, but to do it properly you really need some measuring tools, ie micrometers and, ideally, a bore gauge.

With experience, you can pick up severe wear just with a fingernail (ridge near the top of the cylinder bores on the thrust side, ridges on the main bearing journals where the shell oil groove would be, etc...) but only if you've examined similar before.

But, no offence intended, unless you are experienced mechanically, you can tell very little just by looking.....

Unless something is actually broken in half ......

Schrödinger's cat - so which one am I ???

I think that the question to ask is why do you want turbo engine?

These are generally worn more than standard 1275s, and offer no benefit if a rebuild is required.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

Well the plan is to overhaul the engine in the next 2 years till I get me license then maybe tune it for some RWYB's and daily driving

It's a mini thing you will not understand

you can bet your ass its clapped out, it would be wise to do a full rebuild.

Another thing is, I would hate to get a box of engine rather than a complete engine if you know what I mean. Theres nothing worse than buying an engine in bits and discovering there some bits missing or say pistons that haven't been marked up and you don't know what goes where.

It's a mini thing you will not understand

If it is cheap enough then go for it, but keep in mind it is not a complete engine but more a collection of bits to set you off that can't be bought new, e.g. block, rods, crank, head, casings etc. Anything that can wear probably will have done and will need throwing away and replacing.

It's around £87 . But the whole collection of parts had been taken off a sole metty,back at the same owner

It's a mini thing you will not understand

£87 is cheap if everything (or even majority) of the parts are all there.

what is being offered for the sale, turbo, entire stripped engine and gearbox, manifolds etc?

Apparently this is an n/a mg . apart from the carb and turbo are there any other major differences?

It's a mini thing you will not understand

the cam in the n/a mg is slightly hotter, but will work well for a turbo engine.

the exhaust valves in the turbo have thicker stems and are sodium cooled.

the crank in the turbo engine is harder wearing

the pistons are different.

So if i''ll keep the n/a pistons and add a turbo will i lunch the engine?

And will the crank be a prob concerning reliability?

It's a mini thing you will not understand

the crank will be ok, its just that the proppe turbo ones seem to last forever due to being harder.

not sure on the pistons personaly, but i would expect them to be ok up to about 8-10 psi boost.

I'd have a read up in FAQ matey, not being rude but it sounds like you are starting out and have a lot to learn, however you are in the right place as all the answers are on here for you, but it is for you to look for them.

Yeah i'm a beginner Tom , already used FAQ very helpful but found few bits concerning MG na turbo motor

NA = normally aspirated, e.g. NON turbo

CAM6232 is used in both turbo and non turbo engines and does the job just fine. CAM6581 is fitted to a limited number of turbo engines, with no obvious reason, and seems to be harder wearing than the 6232.
Either of these cranks will do the job just fine.

Have a read of this post-

Thanks TOM very nteresting read .

Just to conferm the n/a oil pump is different from the turbo?

Alot of people use Avonbar or Minispares oil pumps. It will be a slot drive whether N/A or turbo.
