What I mean by building a 2.6 is a waste of time is this.
If you need a new crank, rods and pistons plus paying someone to screw it together and allllll the costs (oil and water pumps, gaskets blah blah) what's the difference in cost of going a bigger bottom end? The bigger bottom end will be a little more exxy, sure. But the end result is so much better. (Some would argue it doesn't sound as good or whatever they dribble on about but that's another debate).
Now, being low mounts (say 2530's or so) and say you cap power at 350 - 380 kw and not spin it to the moon (7000-7500 max rpm), why do you need to build it?
The lasts two attempts have failed. You would have been better off whacking a stocker in it, getting it tuned and away you go. Odds are it would have lasted ALOT longer and driven exactly the same (save for compression differences which wont make a night and day difference anyway)
