Supercharged Austin seven engine advice
#21
Even as an expatriate Northumbrian I can't disagree with those prices, but the bit you don't mention is the labour and machining could add another 5 or 6k to the parts cost. Then to acquire all that might take 18 months because it might not be exactly off the shelf. Then there's only 2 or 3 people I'd trust to build such an engine, and none of those are exactly standing about waiting. Bottom line is starting today it might be 3 years before you got your engine. So the thought of 18 grand, now, for an engine by a known builder doesn't look at all unreasonable.

That’s exactly what I was thinking.

Then it all blows up!

Who built the £18k one?

Charles has built one, I haven't.
I will be putting an Aisin on my engine, not intending to spend a fortune, already have Phoenix crank and rods, Paul Bonewell cam, slipper pistons, enough to built a nice engine, and not for competition so no rules to comply with.

The cost of £2500 was for the machined assembly ready to fit.

The £18k engine was built by Paul Rogers Engineering

And yes, when it blows up in the Esses it gets expensive all over again. 
The call to my wife as I was driving home with a broken car went basically.
 "How did it go?" 
 "I broke the engine"
 "Badly?"
 "Yes, quite badly"
 "I suppose that'll be bloody expensive"
  Muffled excuses and vagueness from me

You need to speak to Zeto’s supplier!

Good luck with your rebuild.

You can do it with a coil crankcase too.
Not that I'm looking to do another!

Years ago, a well known and respected Austin 7 engineer used to provide me with two bills. One I could show my wife, and then the real one!

Thanks for the plug,I am now expecting hoards to flock to my door for special parts!

Here are the specs of my cranks and rods

Crank:  Forged CDM, fully smoothed and balanced.
Rods  : Pot Sheened to 60 degrees, complete with self locking hazel nuts and meringue shells.

I find Elmlea to be the best lubricant with these.
