Note guys, not that I think there is anything wrong with the construciton / performance of a Hybrid cooler...
Just BE AWARE that they are a generic size and shape, not DESIGNED to fit an R32/33/34 GTS/GTR/GTT etc. They have been designed to a price and size, so that the fit a variety of target cars. Unlike a japanese type cooler, which is CAR SPECIFIC (as an aside, I understand that Jpananese mechanics charge like surgeons, so all aftermarket stuff is designed to be BOLT ON with no cutting of bars etc required), the generic type will need to be custom fitted specifically to each type of car. I hope you now see that while the Hybrid types may do as good a job at cooling as a Japanese type cooler, the extra money you spend for a Japanese type cooler is in the design of the placement and mounting kits. I put an ARE cooler on my GTSt (think it was 550x300x100 core) and it got under the reo no problems as it was measured up properly and specific for R33 GTS-t. Personally I would spend the extra money and ensure that I don't cut any structural parts of my car such that a *genuine* roadworthy can be passed.
