ok ive ordered a airtech turbo cooler so will happily guinea pig it for everyone, at £72 it was worth a shot before swapping intercoolers, Rads Etc Etc, after finding and curing a water leak it has seemed to bring the temps down a touch but i belive its running a non standard t2, and different injecotrs so clearly this is not helping my overheating problem at all, as for the Si Radiator fitment you need a front mount intercooler due to the size, i know cause im breaking my old Si and tried it but have been told by a few friends it will be the route to go next if this new bit of kit doesnt work, will update with pics and progress. and as always cheers marty.
