I've done a lot of searching in all of these forums but have not been able to get these questions answered.

1)Has anyone bored and stroked and f23 engine?

2)How far can you bore out an f23, 2.5, 2.6?

3)How much hp could be gained theoretically?

4)Why is this not as popular with import engines as is with domestics?

It seems that this would be an easy way to gain hp and have practicaly a new engine since all new internals are used. Of course hp gains would be assuming I/H/E.

Domestics do this all the time, it's almost the norm IMO. Even Harleys get the same treatment. Why can't we?

 

cause you can only overbore a mm or so at most...
if you put in a darton sleeve kit you can overbore to 89mm and that is it.
