'Busa pistons
Building a spare engine in an interesting fashion (well it's a few weeks 'till uni starts...)
Does anybody know, what hone needs to be taken out of the bores when fitting busa pistons?

Re: 'Busa pistons
I cant answer your question...
...but I am interested in the end product  Is this a slightly cheapish way of making a big-bore SV engine? |

Re: 'Busa pistons
The worlds smallest big bore, only a hone taken out of the bores. Pistons are lighter by 17grams

Re: 'Busa pistons
I though they where the same so it was just straight swap, or have I been miss informed.

Re: 'Busa pistons
No, its reciprocating mass, so it's not exactly got the free revving effect as lightened flywheel etc. (also being considered...)
What it does do, is reduce stress on the rods due to lesser inertia.

Re: 'Busa pistons
Sortof... I'm hoping when I fit this motor after restrictions done that this will cancel out reliability penalty of tuning it to some extent.
