stealth_pug 0 Posted May 27, 2007 hi all, is it possible to use a xs head with a Uk rally bottom end without having to make any other changes? If not what would need doing? thanks Share this post Link to post Share on other sites
TKH 0 Posted May 27, 2007 The head is totally different so you can not fit a XS head casting as a replacement on the rallye. But if your thinking of swapping the Rallye bottom end for a XS one then the pistons have a large dome in the top of the rally. I suspect that at least the compression would jump up. As long as you check clearance you should be ok. If compression turns out to be a problem you can put a thicker head gasket on or even possibly two. Share this post Link to post Share on other sites

stealth_pug 0 Posted May 27, 2007 thanks for clearing that up mate. Just sold the whole car mate so won't need the bottom end. Cheers for the offer though. Share this post Link to post Share on other sites
Sandy 189 Posted May 28, 2007 Do you mean 205 XS and 205 Rallye? If so the heads are totally interchangeable, I think TKH is referring to the 106. Share this post Link to post Share on other sites
