Hi there, My s3 hasnt been feeling 100% from day one and everyday i feel like i loose that bit more power. After all the car has done 175k! so instead of replacing parts willy nilly and never have it running 100% due to the allover wear im thinking about saving up over the next couple of months and starting an engine build. The car will be used for daily driving but a reliable 300-350bhp would be what i am after, i'm just wondering what options i have and what people think is the best way to do it? eg: Buy a used lowish mileage engine, stick some forged rods in it etc etc or is a 175k mile engine save'able? by re-honing the bores and a new set of piston rings and bearings all round? obviously the second option would be cheaper but is it worth the hassle? Its starting to get tappy on startup so i dont think theres much life left in the oil pump as ive already cleaned the oil pickup pipe out. I have built engines before and i have built 1 forged engine which was a ford crossflow so im sure with a bit of learning over the next couple of months i am definately compatent enough to do it myself. If buying a used engine and sticking rods in it is the way to go which engine codes should i be looking at? my engine at the moment is AMK, also what would be needed to get the figure i want? Is this figure acheived with forged rods, standard pistons and which turbo would be best? injectors? i dont mind lag but i do want the car to be driveable off boost which it isnt at the moment, i even bloody stalled it yesterday as it has 0 power below 3k. Im not going to be doing this straight away but a heads up would be great so i can get learning and saving, thanks Obviously it goes without saying brakes and suspension definately need to be uprated as theyre on par with a boat at the moment but i can deal with that lot in the mean time, i was thinking about getting a mk5 golf r32 as i came from a mk5 golf and i do like them, but it will be cheaper to do this and i do enjoy tinkering with and tuning cars so why not ey, you only live once.
