Blaasaaaaafjgfhdhdh!!!
Why am I having such trouble with this last piston, the other 3 were fine, this one yet agin had got stuck here whilst putting it on,
If I apply any more pressure with the press, I feel the piston will crack like last time.
Suggestions?

You tried heating the piston in an oven and freezing the pin in the freezer before trying to put them together? The pin will just slip in........

I wish I had gone for the Polo one instead of the 206. That's more to do with space (mini conversion).
A 4 2 1 is apparently better for lower down the rev range than a 4 1.
So the Polo will be better for a road car but the 106 will be easier to modify.
It would be handy to get a cardboard template of each of the flanges and offer them up to the head to see how close the port spacings are. Or buy an exhaust gasket for each and then sell them on Ebay when you are done with them.

don't forget the egr valve pipes will give you nice stainless micra flanges
I didn't think the Micra had an EGR system?don't forget the egr valve pipes will give you nice stainless micra flanges
sorry that wasn't very clear was it! VW egr valves have a stainless link pipe. if you look on eBay for "vw egr pipe" it'll come up. You buy two and lop the flanges of and the flanges are an extremely good fit to the micra exhaust flanges. ill try and find one to explain
Found the link, I had taken a prinscreen of it ages ago on my iPad to aid my memory

Yeah, think that'll do it mate

I put a saw drift in mine and used a sash clamp. Yours looks much closer. If I was doing mine again I think I would heat it and bend it as welding the branch back up was a pain.
Also worth bolting to a BIG chunk of steel to stop the flange bending. I didn't and had to use a press to get it straight again.

Had a quick go at the manifold today......ran outa stainless wire
Lined up ok, had to slice the right tube a bit to get it to bend, apart from that, bit of brute strength and lined right up
Need to do some dremmeling on the inside of the tubes to get the edges smooth

Can anyone measure the space between the head and the bulkhead on a k11 for me?
None of the scrappies round here have any micras
So can't measure stuff

hmm 10" from back edge of cam cover as it starts to curve downwards from the top surface to the raised seam on bulkhead, so 11" ish to bulkhead in the centre, 12" where it curves a bit around the servo bulkhead area.

Have you checked this on the engine? Looks like it will hit the bell housing maybe?
Major heat transfer?................Yeah, loads of room, can fit at least 2 rizla papers between them
Is a bit snug!

oil seal being the first point of concern.....
I was thinking more of heat transfer into the gearbox, via the aluminium bell housing.............Think it'll be fine
The cg10 flywheel I got from frank has had loads taken of the back of it, so plenty of room there, other than that , not much else the heat will affect I guess
