ever thought of running the turbo transverse and reversing/stacking coolers? sorta like v mount but with a short and wide (11x31) rad mounted in the intercooler position and the intercooler mounted to the upper rad support (22x12)?
you would be one less bend into the turbine and one less bend into the compressor.
depending on intercooler height it could make it so you dont need the oil scavenge pump and so intercooler piping was less than 2 feet.
you would have to fabricate new rad hoses but its not like you havent done that to a point already. and it would allow you to use more off the shelf parts.
the only disadvantage i can see is that exposed surface area for the intercooler could be reduced for the intercooler on 02-05 models.
