I was quoted 255 / piston, ex VAT and shipping.
Why would you need custom pistons anyway?
your just going with a bigger bore, and there are kits out there for a 3.2>3.4 upgrade...
You do realize your going to be broke and without GF if you don't curb your enthousiasme before it's too late???
you got a 3.2 , those are flat domed, no valve pockets needed, no twin plugging... what's there to customise?
All you need is the same thing, but with a 98 mm bore...
it's a standard Mahle kit

you'de only need something that ain't flat, if you change the cams to a hot spec, in which case you'll need new rockers, twin plugging, new intake/cpu... might as well sell me your roller for 500 bucks and get yourself a 3.6 from the get go
