Help needed with engine parts.
Turbo Mini Forums

Ok chaps, Tidying my shed earlier today in the hope of building my engine over the next few months, time permitting. Now I'm new to engine parts at this level so would love some advice and opinions from you guys who know more than me on this.
Below is a bunch of pictures I took today with some questions attached. The block has already been machined to match my cast omegas and had new cam bearings fitted and deck checked for straightness.
All opinions are welcome as I don't want to build this engine and find something wasn't right or up to the job.
So here goes:



Whats the story with this timing gear? Is it adjustable via the holes in the centre of the large sprocket or would I need an offset key? Or am I being really simple... Is that an offset key???




Is the timing case suitable?






Does the crank look ok? I appreciate that you can't give a 100% because it's only a picture. Just after a rough idea.



Anyone know what oil pump this is?



Am I ok to re-use cam followers or should i just buy some new ones?
Also is that a tensioner at the bottom of the picture, and if so is that pin next to it to fit into it like a hinge? Any other relevant info from these parts would be helpful.






Is it worth having someone look over my cylinder head?



Is this a metro turbo dizzy?



Does my cam just need a good clean?








Lastly should I attempt a full gearbox rebuild or stick it in after a clean? Also what do I look for so I know if I have a 4 pin diff etc etc?

Many many thanks guys, think I may have bitten off more than I can chew.

The tiing gear is dowel type adjustent so no need for offset keys. U just more the larger sprocket around by taking the dowel out and putting it back in where u need to. The timing case cover will need slight modification with a hammer and the backplate will need 2 bolt holes recessed so the bolts dont hit the timing gear. Personally I would chande the cam followers and you can get rid of the timing chain tensioner. The dizy is indeed an electronic 1. The cam depends on what it is and what you want from the engine. The gearbox rebuild is a very difficult question to answer without looking at it but I would put an uprated diff pin in it

Masturbation is not a crime its a hobby

Looks like it's got a x pin in there already.

Timing case has already been modified to clear the duplex.

In the 13's at last!.. Just

The two holes that need countersinking are already done too.

That gearbox has a minispares X-Pin diff in it already.

Cam looks okay, if that's the worst lobe I would fit it.

With the cylinder head I'd measure the chambers to see what compression ratio you'll get, it might need to be sent to one of our head wizards anyway. If not a strip and refurb should be adequate.

Buy new followers

The pin is for the tensioner yes, goes in from the back so the head sits in a whole in the timing chain backplate, against the block.

Oil pump looks like the standard 1275 one, worth replacing anyway, don't want it failing.

It all looks daunting to start with. Just tackle it step by step and do your research, there are lots of videos on youtube from minimania about how to check clearances etc.

I'd get new cam followers, but the crank tail doesn't look too clever, the heat marks might suggest the flywheel has been slipping on the crank, best to get that checked out.

Thanks a lot guys, last year I bought myself the 1380 engine building DVD so will be using that along the way. Just need to save up for the parts I'm missing now.

It might be worth a trip up to see Benross with the crank and head.

The head is also 11 stud, has the block been converted too?

MITP 2012 17.01 seconds 1/4 mile against "The Don"
MITP 2013 16.83 seconds 1/4 mile

what is the reference of the dizzy? you need this to check if it comes from a turbo engine or not...

Is there much advantage in fitting this dizzy over a standard metro one? Dizzy will be getting ditched for electronic ignition but not for a while yet.
Also the block is converted to 11 yes. Just not pictured because its already been worked.

Turbo dizzy's are slightly different from standard ones as advance with boost.

How do they advance with the boost. Is there a link anywhere showing how to wire one in?

Its in the dizzy itself pal

No they don't advance with boost, infact that's the opposite to what you want to happen.
The Turbo dizzy has a different advance curve to other models, so is often used as a starting point. Though as soon as you start modifying things it's unlikely to be anywhere near optimum really.

I'll just be using it until I can afford to replace it to be honest

I would spend a bit more on megajolt. By the time you get it on the rollers and get the dizzy sorted, to then go back later and have it tuned with aftermarket ignigion is false economy. I wouldn't run a tuned engine with std dizzy. If timing is out you can do more damage to the pistons lands and that would cost more than the cost of a decent ignition system

That head looks interesting. Is it an MED one by any chance?

If something is worth doing, it's worth doing half of.

Cheers Phil, for the correction.
I was always under the impression they did something on boost, never really looked into it though.
Always seem to get the terminology wrong too, must be a retard

In the box, the third motion shaft bearing is knackered and needs replacing.
