Since I have already cut 7 x 1 mm threads in the plug holes of the crank I do not really want to drill and tap them to a larger size. Since not being able to find 7 mm grub screws anywhere on the planet my next resort is to try 1/16 NPT tapered plugs which are easily found. The 1/16 NPT tapered plug...

looks like I will be inserting 7 mm bolts tightend into position then saw off flush to the crank web.

TS_TURBO is it necessary to plug the main crank journals of 2 & 4 after drilling in the block for additional oil supply to the bearings 2 & 4

I have removed the aluminium plugs from my 2.0 litre crankshaft and put a tap through to make a 7mm thread. (I broke 3 taps doing this process!). I now require 7 mm grub screws. Does anyone know where I can get these? Preferably in Australia. I could use bolts sawed off after tightend in position bu...

Does anyone know what material the cylinder liner is made of on the 2 litre engines? grey cast, nodular iron, ductile iron?
Is there a better alternative to the standard item?
I have heard of several modified high power engines having a liner split from detonation.

A successful way of removing the liners is by fitting a top compression ring to one of the old pistons and fitting it upside down the bore all the way down till the ring expands past the bottom of the sleeve. Then you can punch it out with a block of wood and a mallett. You may want to use some pene...

Maurizio, Thanks for that info. I was concerned as the head of the twin spark is 25 mm taller than the Nord engine. I thought the filler cap may hit the bonnet. The GTAM engine in the rally alfetta gt has the filler cap towards the back of the tappet cover. Plug leads are not a problem as I have mad...

Maurizio, I have come in to this discussion a little late. However I am currently building a performance TS engine engine. The head is from a 75 and are matching it to a alfetta nord block. A lot of work! I think the 75 and 155 TS have a 90 mm stroke crank which is why the rods are 1 mm shorter. So ...

Can the twin spark engine from the Alfa 75 fit with clearance under the hood of a Alfetta GT (4 cylinder hood)?

Thanks,
Dom
