Why don'y you try Spyder who do the Elan Zetec conversions they may may be able to point you tpwards an owner who wants to sell.
I am amazed anyone who has owned one would want another, They have had their day seriously unreliable engines compared to a Zetec or K or even a BDA.

Certainly very old hat, they were the engine to have when I was at school, quite quick then but not now.

That's all BDA stuff I think, couldn't see any mention of Lotus Twin Can parts?

15k and it's a pile of bits, what a total rip off
For that you could buy a good BEC and get some real performance
There must be some real numptys out there

Cheapest place I've seen 907 engines for sale has been inside a Jensen!
They go for around £300-500, then you have the joy of breaking the car for spares!

I still have the engine and box from my mk2 Lotus cortina, all that was salvagable when the car was rear ended in 1981. Most definately not for sale,
one day I will find a home for it in a mk1 or 2 cortina or mk 1 escort.
But, the majority of twin cam heads had cooling problems, cos the wires used during casting to create warerways couldn't be pulled out, very
prone to warping etc.... A nice peice of history but I wouldn't depend on one to get me to the corner shop.
Zetec is the way unless you're after 100% originality, and have a car trailer.

I think the OP was looking for the original 1500 Kent based 1558cc Twincam aka Twink.

Never encountered cooling problems apart from leaky water pumps main problems were valve gear related --- timing chains, valve guide wear, propensity
to crash the valves if over revved.
Loads of other nuisance stuff like oil leaks from just about everywhere and on the Elans & Mk1 Cortinas 2 bolt Anglia starter motors that
weren't man enough for the job.
Real problem is a 1600 twincam engine with only 2 big angled valves per cylinder is never going to be reilable if revved to 6,500 rpm plus.
With a modern 4 valves per cylinder the much smaller valves and camshaft lift the likely hood of valves making contact with pistons is so much less.

Yes the BDA family were a whole different ball game from the Twink, in club racing the BD series (and FVA/FVC) were a lot more reliable than the
Twincam and of course the didn't run into the power out brick wall the Lotus engine did. By the mid seventies a good Clubmans A class spec Xflo
was more powerful and more reliable than a Lotus engine.
The name to be reckon with in Lotus Twincams was Vegantune I had one thier engines in my Plus2s.
Of course the Sierra Cosworth lump immediately made the Twincam, BDA & BDG seem pretty expensive to run.

As BT said earlier, even Spyder engineering have moved away from the Lotus twink.
Their own modernised Plus 2S uses a Zetec. 400 extra CCs and twice the valves. Mmmm, let me think about that.
Don't get me wrong, a Lotus was a great thing, but the cost in getting the numbers a modern engine makes is astronomical.
