Hi , new to this site, after some info bout a project iam working on, a p100 with 4x4 running gear , currently running with a 2.8 , have a 2.9 with a TT twin turbo set up i want to drop in. Have stripped the engine and need new pistons , what i would like some advice on is should i pay out for pistons , £800 , rebore etc, i hadnt planed on that expense, is it possible to fit differant , ie, cheaper pistons ? maybe look for another lump ? anyone got any ideas ? cheers
