Bore & stroke, redline???

[spetz]

My engines bore & stroke now is 78 by 69mm
There is a hybrid engine available for this (6A12 MIVEC with 6A13 block).
So basically the MIVEC heads are joined with a 2.5L V6 block.

I was wondering what the extra capacity, namly the stroke would do to redline? 6A13 is 81.0 x 80.8mm

The engine has forged conrods and pistons, 12:1 CR, and of course is/will be mated to ported heads, big intake manifold, extractors etc and even stage III cams.

Anyone have any clues?

Mean piston speed will be higher.
Unless the parts are designed for the application, the redline would be less than stock.
Seriously though, if the engine has the parts you mention in it,
Talk to the man who built it.
FWIW, There is not a great deal of aftermarket support for these engines,
So do be wary.
Personally I've no idea why you would want a MIVEC orphan.

Mabey because it's a 2.5L 12:1 CR MIVEC V6 in a sub-1000kg car? :D

What PhatSol said!
Just imagine the torque in that thing...
What does FWIW mean?
