I know there are titanium pistons, but I doubt there's any standard product for the Evo. If you get them made especially for you they'll be VERY expensive. I remember Honda made a bike (Some NSR, I think) with titanium pistons but it never made it to big numbers partly because of the cost of the pistons and some durability problem I think...

I asked Mike W at RRE about this. Here is his reply:
"The HOK guy is correct in the newest post. The turbine wheels of the turbo (exhaust wheel) is a titanium/aluminum alloy (TiAl)
The pistons are 8.8:1 compression and have oil cooling pssages in them but are not interchangble with DSM vintge stuff since the motor is backwards (valve dish cut outs in the piston are opposite of what they need to be).

Wish they would fit forged pistons as standard but sadly not. JUN do them as mentioned byHOK.
