2.5l upgrades for the NA I5

[Mihnea Cotet]

Hi guys!

I've just done some mathematics and geometry today to see if a 2.5 crank 
coud fit in a 2.3 block.
This 2.5l engine uses a 82.5 mm bore size with a 92.5 mm stroke. As opposed 
to the 86.4 stroke for the 2.3.
The problem that resulted was that either the stock block is 5mm too short 
to accomodate for the longer stroke or stock rods are 5mm too long.
The distance between the holes in the stock rods is 159 mm for both engines.
What could be the solution?
Cutting/rewelding the rods? "Prolongate" the block? The latter seems pretty 
much like Sci-Fi :))!!!

Any BTDTs?

Thanks,

Mihnea
