Turbo Mini Forums

I was looking for them plugs for ages, never managed to find anyone round here that sound them!

Coming on nicely!

oo coming along nicely. mine is nearly all done now with the maching work.

if people would like i'll get a load of plugs just like that from work and i'll send them out for what ever the postage costs, or free if i can get it snook though at work.

yes please!! it will help with my next build

pm me with your details. im out the office all next week, (weeks hol to get my mini sorted) But i'll be back after the bank hol, if any one needs ANY pneumatic bits let me know and i will get hold of them for you.

Not sure yet. looking at it i think we may have to put a bigger chanfer on the top of the bore. will have to see after when i have done the dry build.

If i cant get a good enough CR then i can always whack a turbo on it!!

very nice work.. are you going to be using the SC gasket as you are dry decking?

That sir, is not rust, it is the progressive mass reduction system

Yes, using the SC gasket. I'm basically following the SC guide with the exception that I'm shifting the bore centres to avoid fouling the exhaust valve.

Bit more done today:



Milled the top of the plugs level with the deck:



Now I need to estimate exactly how much to shift the head over.

Paul where did you get those steel plugs from?

Wolfie,

They are malleable iron. Link up there ^^^^^^^^^ somewhere

are you moving the head towards the alternator?

are you moving the head towards the alternator?

Paul, sorry this might seem a stupid question but whats to stop the plugs unsrewing? i can see some sort of threadlock but wont the heat break that up and let them unseal? with the block being thicker than the plugs how will this effect them heat wise

not trying to be funny i am not an engineer

Wolfie, the plugs are tapered so when you screw them in real tight, they grip real well! back that up with loctite ( I opted for high strength high temp retaining compound) to give a leak free seal. Also the rate of expantion of the metals will be pretty mush the same. I opted for brass plugs where no studs intersect in the theory that brass expansion rate is higher than iron and the will wedge themselves tighter when the engine is warm :)

Paul, it may be ok on the small bores but just so people are aware, moving the head forward and using the Specialist Components gaskets will not work. This is why i have a 0.6mm gasket available to anyone who might want it, at the right price of course

why doesnt that work Sprocket?

Yep, moving the head towards the alternator. Only a couple of millimeters at the most.

I'm guessing that this does not work on the large bores because the gasket would end up overhanging the bore. Am I correct?

i did think about doing this but i was too far into getting the machine work done. Hopefully it will be ok.

SC gasket should be ok on a small bore i reckon.

I have deviated from the SC build guide with the pushrod holes.

On a 1275, it would be OK to press fit a bung, because the bung would be bigger than the hole below.

However, on the small bore, if a bung dropped through, it would be in the gearbox in no time. Hence I've screwed in a plug.

what are you going to do about thrust washers?

will you be doing a lot of welding to the head to get the dry decking to work?

and how will you coolant flow? reverse?

I'm a bit phobic about ruining the heat
treatment by welding the head.


is the pipe in the block brazed ?
