Right i have a spare engine fully working order removed from my other GTI had 120k on the clock run sweet as a nut but as its a spare engine i would like to rebuild it fully.My options are rebuild it back to standard or bore it out and have lots of work done depending on what advice i can get on here and how hard is it to source parks for these cars like racing bearings forged internals stuff like that i have an in house engine re-builder at work will all the tools so just need parts what can any 1 suggest. I have a misses and little girl so need something reliable but when im alone power im not looking for 300 bhp or something silly like that if there is a reasonable priced option for and extra 10 - 30 bhp i will be happy.Any one know anything about superchargers on these engines....Any suggestions??
