So frustrated, I put the on the back burner for now and tried to fit the new front bumper and brackets to see hom much I need to widen it. Brackets and bumper aren't even close. I got 2 different front bumpers and neither fits, so that will need to be modified. I should have taken pictures but I forgot to.
Next, I tried test fitting the radiator in a few different positions to see what could work and what wouldn't.
(A)
(B)
(C)
Had to trim the front section of the spare tire well some more to get this to fit
(D)
pretty much like (B) but a slightly different angle and different bottom mount
Originally my plan was to route radiator exhaust through a hole in the hood ala mitsu evo 8/9. But if I can get enough clean flow to the fender wells I won't cut the hood which will probably look better (stealthy) anyway. I also need to make sure there's enough room for the radiator for the air-water intercooler.
