for the stress relieving it was done with all the engineering so ive no idea on cist but id imagine any competent engine builder/engineer should be able to do it

no idea on cost for the management as it depends exactly what you want, i guess motorsport developments is nearest to you for that stuff in blackpool.

cheers for the inlet comment, cant really take credit for it, one mate sed... 'i know what will look the tits... ill get it done' then his mate (rich_frst) did it well chuffed with it
