would that mean i have changed the compression ratio to from the BWA to that of the S3? what could the benefits be apart from piece of mind

Well im running mine on a 3076R at 22psi at the moment.. Thats well over 400hp.. :happy2:

so uprating the pistons and rods, would mean im running the same compression ratio as the S3?...anything else that would be needed for the swap apart from the pistons and rods?

Yeah, your compression ratio would drop from 10.25:1 to 9.8:1..
I can't think of anything else, just a head gasket and a couple of seals etc..

hmm interesting. thats a definate possibility, i know of someone with the top end of an S3 engine incl cams etc that i dont think he has fitted to his K04 vRS, so that and the S3 pistons would mean id practically be running an S3 lump i guess.
I presume require a special revo stage 3 map to take into account the different compression ratio and cams. id be happy to call it a day for the car after all that me thinks, provided i dont get a ride in any BT GTIs or leons :surprised:
