I bought the windows off mike templar on ebay, cant see him on there at the moment tho, rally design do them tho, so they are available.
I'm really enjoyin this project been just under 2 years with it now, hopefully will be out for next summer. Is good not using a yb for a change, quite abit of potential in the zetecs and there plentiful right now.
I'll try get a pic up of the tops of the pistons, they have valve cutouts machined in them if that helps, there 9.0:1 compression, been lookin at altering this tho, will be getting stuck into the engine very soon.
Thanks all for positive comments it really does help drive you on in a project
