i don't have a gti head...
but i do have a standard 4g93 head from a mitsu engine...
it's has the same spec, size and performance as GTI...
call me 0123009602 for more details!
Besides 24 Hours Nürburgring, 24 Heures du Mans, the Tokyo Motor Show and the Nismo Festival, I think WTAC would be another motorsport venue and event...
