_leon_ 0 Posted June 14, 2006 also remember compression ratios - higher for charger, same as standard or up to 8.5:1 for turbos. i would really recommend you to ask as many questions as you can and discuss options with the tuners to start getting ideas of where you want your project to go - trust me it takes time!

Blue_Joe 0 Posted June 14, 2006 iirc vag state the maximum bore diameter is 82.5mm. However 83mm has been proven to be ok. A lot of people seem to insist that you get your block ultrasonically checked before going out to 83mm. Mine are bored out to 83.5mm - But this is as I mentioned earlier quite extreme!!!! :twisted: Quote Share this post Link to post Share on other sites
Rob_B 0 Posted June 14, 2006 mine is 83mm with forged pistons and works well with some nice power. retained the G60 crank with some nice knife edging and balancing. not as extreme as some others but with a ported head it goes well and i havent had all the engineering issues that others have had Quote Share this post Link to post Share on other sites
