Hi Si,
I wonder if you might be able to help urgently, i have been working with Synchro motorsport (Basically honda in swindon) we have fitted a K20 into a jazz with proper sequential box etc, it flies, it also uses an evo 6 rad which has just let go, i dont suppose you might have a spare one kicking around i could have/steal/rent/buy???, we are supposed to be testing friday at silverstone.
Cheers
