Even if you fit OS pistons, your still going to have to fit new rings so...yer. I have the full 0,5mm oversize-set lying here, i.e. pistons and rings :-) Re-ringing a used engine and pussy-footing around "running it in" can ...

Even if you fit OS pistons, your still going to have to fit new rings so...yer. Re-ringing a used engine and pussy-footing around "running it in" can result in glazed bores very quickly and incessant crankcase blowby. So ...

... It seems a set of rings would set me back nearly the amount i would have to pay for boring and honing the block. As i have a set of oversize pistons lying around, i think i would rather go this way. In the actual engine i replaced the valve guide seals about 2 weeks ago, but unforunately ...

... for about 10 bucks. Nistune is fine and with the appropriate software you can allow for a million psi of boost and enough rpm to send the pistons into orbit. You just have no decent features is all. However, if tuneable but stock appearing is your thing then forget all those 2 bob piggyback ...
