That's it, bottom end done at last!
Since I couldn't find an Alfa 75 flywheel anywhere it's ended up being a low compression (approx 8.0:1) 2.8 using the 3.0 block / liners and crankshaft / flywheel from a 2.5 gtv6.
I was planning to use the lovely forged high compression pistons I got (plus new lightweight rods) to make a turbocharged engine eventually, but realized:
- The 2.5 crankshaft isn't nitrided so will get damaged more easily
- Putting 300ish BHP through a chassis designed for a max of 168 (in the turbodelta) would be a bit silly
- It should still make all the correct Busso noises but I won't have to worry so much about using strenghtened transmission components or blowing the standard transaxle to smithereens
- It should work fine with the standard 75-type l-jetronic ignition / injection system which I have in full, which will save me having to spend another age searching for bits to complete the partial 164 motronic system I've got
So now, at last, I can move onto doing the heads and then transaxle
All of which means I've got a big list of excess bits which I won't be using:
https://www.ebay.co.uk/itm/293222519210gtv6 2.5 short block
https://www.ebay.co.uk/itm/293203391840Alfa 164 loom - untested but all appears to be intact
https://www.ebay.co.uk/itm/293203391854Alfa 164 Motronic ecu - type 0 261 200 11. Untested but contacts look good
https://www.ebay.co.uk/itm/29322697377275 / gtv6 inlet trumpets and injectors - not tested, assume the injectors will need a clean!
https://www.ebay.co.uk/itm/29322740877075 / gtv6 2.5 12v cylinder heads - appear to be in great condition. I've kept the oil pump drive and camshaft sprockets but could stick an old, rusty set on if you need them
https://www.ebay.co.uk/itm/29323205736675 / 164 3.0 12v crankshaft - seems to be in pretty good condition from my measurements
https://www.ebay.co.uk/itm/293232058248156, etc 2.5 24v crankshaft - appears almost unused
https://www.ebay.co.uk/itm/293203391795164 3.0 12v inlets plus Motronic injectors Not used in ages so will definitely need a clean!
https://www.ebay.co.uk/itm/293226967731164 3.0 12v 'distributor' plus cover, cap and rotor Rotor arm isn't the best, but the rest is in good condition
https://www.ebay.co.uk/itm/293203391775164 3.0 12v 'distributor' Not the greatest, but it turns ok
https://www.ebay.co.uk/itm/293226967147164 3.0 12v 'distributor' Not the greatest, but it turns ok
https://www.ebay.co.uk/itm/293227391116those lovely Wossner forged pistons - brand new and unopened
https://www.ebay.co.uk/itm/293203391794916 gtv, etc 24v rocker covers - good condition
https://www.ebay.co.uk/itm/293227404086116 gtv6, etc 12v rocker covers - good condition
https://www.ebay.co.uk/itm/29323102534675 / gtv6 Busso sump - good condition, but will need gaskets. Just what you need for a fwd to rwd Busso conversion, along with:
https://www.ebay.co.uk/itm/293226757655Alfa 75 / gtv6 oil pump - Some scoring on rotor and can't claim it's perfect / unused, but it's within tolerances, and at least you know what you'd be getting
https://www.ebay.co.uk/itm/293226762861Alfa 164 12v oil pump - Some scoring on rotor and can't claim it's perfect / unused, but it's within tolerances, and at least you know what you'd be getting
https://www.ebay.co.uk/itm/293226766950Alfa 164 12v oil pump with pickup - This one's in surprisingly good condition
https://www.ebay.co.uk/itm/293226767995Random 75 / gtv6 / 164 12v oil pump bits - Rescued from the bottom of a parts box, may come in useful to someone
https://www.ebay.co.uk/itm/29322678588075 / gtv6 / 164 12v main bearing caps - Another rescue from the parts box. Seem to be in pretty good condition
