2.8 short stroke question re: rods

[Tricky D]

Which rods do I use, the 2.2 rods that go with the short crank, or the 3.0 rods that go with the pistons?

[Scott Clarke]

A 66mm crank requires the use of the 2.2 or 2.0 rods. The distance from the wrist pin to the top edge of the piston is the same regardless of application.

[Tricky D]

Thanks Scott. Fortunately I have the rods, just need to get them reconditioned.

FYI, for everyone else:

- 66mm crank & rods
- 3.0L pistons
- 3.0 1976-77 Euro Carrera or 911 Turbo Case

= 2.8 short stroke...

Wayne,

What makes the 76-77 case so special, i.e., how do they differ from later Euro Carrera cases?

There is no other "European Carrera" per se (I guess you can call the 3.2 European versions a Euro Carrera, but no one does).

The 1976-77 Euro Carrera and Turbo (Carrera) had an aluminum case that can accept any crankshaft from 1965 through 1977. This allows you to plug this engine into any 914-6 or early 911 without any modifications to the transmission or clutch setup. This also allows you to build a short stroke 3.3 for use in these cars, or a short stroke 2.8 as detailed here.

It's a very rare and useful engine case.

Thanks for the insight Wayne. Perhaps you might consider adding this explanation to future editions of the book (or did I just miss it)?

One other thing, if I may. Are there any particular case numbers I should be looking for, like 930/52, 930/02, etc.?

Thanks again for indulging me.

Yes, you did miss it. See page 112 at the bottom.

See Appendix A for the list of the Euro Carrera and Turbo Carrera engine cases. When I found my Euro Carrera engine case at Pomona, I had to run back to my booth to get a copy of my own book to look it up!
