i cant Recommend him enough his attention to detail and sheer knowledge is unbelieveable i know him Personally have helped him strip down and clean engines before work commence if you are having trouble getting through to his by email i ma going to see him this weekend "havn spoke to him for month's".my old 1.9cvh with a stage three head use to produce 240bhp @ 22psi with his head went up to 296bhp 298fbt @ 22psi flows 10%cfm less then a ported 16v zetec. brom at zoo motorsport has built me a 2.0 zvh with the following spec........

zoo motorsport built 2.0zvh eagle steel rods je pistons 7:8:1 compression ratio
David Newman custom cam
Pumaracing 45mm valve race spec larger insert cvh head with custom double valve springs
Gt25/40r 0.64 dual roller bearing turbo Simpson’s race exhausts tubular manifold hks filter
Zoo three inch exhaust system from the turbo back
Zoo turbo pre-rad and oil cooler with remote oil filter
Zoo spoon style inlet manifold with 45mm ram jets
Grs fm cooler grs 520mm rad
Uprated escort cosworth fuel pump
S8 ecu running coil pack, closed loop lamba
750cc injectors as well as supplying more fuel then my old dark greens these are a much superior injector due to the spray pattern coming from six port hole nozzles instead of one for better fuel atomization. These supply 56cc less then eight greens.
Zoo group a engine mounts and gearbox cradle. This what I can remember so far.

with the flow rate of the head and turbo there is no reason why at 2 bar this engine cant produce just over 400bhp on my last spec 2.1zvh L8 ecu same turbo but normal efi manifold, greens, two inch exhaust from the turbo back which was strangling the power, and the cam shaft not dialed in properly. engine produced 311bhp 296fbt @ 19psi but was starting to run lean I might not even make that figure but the Potential there, i will know for Definite in two weeks time.... hopefully ready for santa pod october 15th
