Swivelonit 119 Posted July 5, 2013 Report Share Posted July 5, 2013 I will be turbo charging the MK 4 in the next couple of weeks, all sorts of things have been purchased and I am now at the point of planning compression reduction to about 1:8.1/8.5 I am thinking of a head spacing plate and two head gaskets. I would like to know where the spacer can be bought from and secondly what other options are available for reducing compression? Link to post Share on other sites
Daverse 175 Posted July 5, 2013 Report Share Posted July 5, 2013 Either a headspacer to lower compression, or use low compression pistons, but their usually big bucks. Link to post Share on other sites

Swivelonit 119 Posted July 5, 2013 Author Report Share Posted July 5, 2013 Thanks guys, I will get me one ordered up, I have the diff to do this weekend and then it will be a few fiddly bits to pass the MOT, once that is passed Project V6T gets under way. I will keep the build up to date on my other thread, car will also be de badged and look very stock with scratches included! Don't want a flash looking polished Golf as this will make it stand out, not what it is about IMO. Link to post Share on other sites
