Alpha Twin Cam / pinto swap
Currently running a 2l pinto with twin 40s and Burton fast road cam. Still feels a bit heavy up front and lacks oomph.
Am thinking of swapping for an Alpha Twin cam or twin spark engine and box. Is anyone using one of these engines and could give a bit of advice?
What is best advice for selling the pinto (which runs great). Sell as a unit or split, carbs, head etc.
Thanks
Gary

Which box will you use?
The T Spark is a nice engine but there are many other engines that would be easier to fit.

Normal is getting dressed in clothes that you buy for work and driving through traffic in a
car that you are still paying for - in order to get to the job you need to pay for the clothes
and the car, and the house you leave vacant all day so you can afford to live in it.

The Alfa twinspark 16V engines must have the cam belt replaced every 36000 miles or 3 years.
Otherwise, it is very likely to fail resulting in not only bent valves, but also damage to the big ends (due to the shock imparted when valves meet
pistons.) Though this wouldn't necessarily be evident 'til about 1000 miles after replacing timing belt!
The 2.0 also has a balancer shaft belt which should also be replaced at same time as cambelt (has been known for them to fail and wrap around timing
belt causing it again, to snap. The Twinsparks also have a 'variator' which sits on the exhaust cam to alter valve timing as revs rise.
Again, it is economically viable to have this replaced at same time as cambelt.
Expect to pay around £400 - £500 for all the above to be repaced by your local Alfa independent specialist.
Its still not cheap to a diy replacement, as you must buy and use the proper camlocking and tensioning tools - otherwise cams will slip during
replacement resulting in incorrect valve timing.
The earlier 8 valve twin cam engines have chain driven camshafts and should last around 100,000 miles.
If you've got the room, why not fit an Alfa V6? They sound absolutely terrific!

I totally disagree with the idea that a bursted cam belt will cause the bottom end to fail. I bought a 156 with a busted belt and fitted new valves,
guides, a complete set of belts and tensioners, as well as all the gaskets etc and it cost me about £250 in parts.
Due to various web experts, I took the sump off and checked the main and bottom end bearings. They were all totally unmarked with no signs of damage
and they were all totally concentric.
I put 12k miles on the car before I sold it and it's still going strong!
Cracking little engine but as said before, there are better ones!!

Better ones like the 3.0 V6  now if only I could find an easy way to match it to a ford box I'd have one in my car tomorrow
