Twin Spark Berlina

[Colin Byrne]

yea its crazy how much bump steer these cars can have in them with semi standard setups

what ride height are you running? we're both running fairly standard ride height to get some decent ground clearance

[LaStregaNera]

lower than you I would imagine, but not super low, see pic

[Paul Byrne]

Just to clarify track rod end points change to reduce bump steer with the risers in place.
I meant that I changed the pivot points so that there was a 15 to 20mm increase in the height of the outer pivot relative to the inner. I raised the outer by about 5mm and dropped the inner by about 10mm.
Hope this clarifies!

[LaStregaNera]

Yep, got it now

[Divano Veloce]

The gearbox did NOT want to be left behind so they both came out... I think it was binding on the spigot bush which pulled out with the gearbox

next off with the head. Again I used the block and tackle to save my back

Off with the battery tray

Engine bay after a wash.... When the TS motor was installed the owner had the engine bay painted... Thanks Nigel!

[Divano Veloce]

All pistons look like this on the inlet side, the rest of the skirt looks perfect


Big ends all look pretty good

[Divano Veloce]

No more bench space...

[Evan Bottcher]

By the time I'm done I will have a car that's probably too nice to enjoy the way I have....

Nice video, but you should have had your sleeves rolled down. Pit lane marshall slacking off 

[Divano Veloce]

Fark.. That's why I hadn't posted this vid...  Whoops

[Divano Veloce]

Turns out spare sills are a mixed bag. At best 1.5 lhs sills.... However unlike coupes the sill profiles are straight/parallel so can be easily made.

Nord rods perhaps? Bump up that CR...

[GTVeloce]

I think you should be able to re-use most of the TS bottom end. I doubt there is any issues with the block itself. A set of second hand nord rods in good condition would be very cheap. Get the original crank checked out for balance and condition. New (probably over-size) big end bearings. Have the pistons and liners checked for out of round etc. Then maybe have your pulley checked for balance as well.

Should be fairly cheap; be balanced; have slightly more compression and still have the TS motor. Only potential major problem would be if you need to replace the pistons and liners or crank.

I'm just envious you were able to pull the head off so easily! I'm guessing it has been off not that long ago.

[LaStregaNera]

I vaguely recall the nose being slightly different.
I'd re-use the TS crank - alfa cranks are pretty solidly overbuilt - maybe throw a can of dye-pen at it to check for cracks, but i reckon you'll find it's ok. They're Nitrided, so it's pretty rare that the crank needs re-grinding.

I must have missed it, what's the reason for engine stripdown?

[AikenDrum105]

The nord cranks are a little different on the nose - but there's also a difference on the radius on the edge of the bearing journals. earlier nords have a sharp edge where TS cranks have a 2mm radius.   You have to be careful to check the bearing shells you use are chamfered on the edges to allow for this radius in on a TS crank  (or just chamfer an earlier set with the edge of a steel ruler - thanks Vin...) 

I've been using an earlier 2L nord crank in the last two iterations of the TS in my super.  (because that was the crank I'd tapped grub screws into the galleys on already...   )

Ben's right - the nitrided cranks are super tough...
