Ok people I had dave from ASE do me a custom cooler just before xmas. Core size - 450x450x75 Biggest possable able to fit WITHOUT having to grind anything, we deleted the inlet pipe crossing over the top of the cooler allowing more height.All that is required to fit is drilling a new mounting hole,relocate the horn,relocate the tranny cooler and a small bend in the a/c pipe. Obviously we built a new cooler pipe from the turbo to the cooler as well. I think Dave is going to sell these as a complete kit as well, you would need to check with him.
