I am going to try this one, since i am in same postition in finding a intercooler for my self. Is this core for RB25 or 26? I have found a couple that will work with an aftermarket intake plenum. Arizona Z car makes a pretty decent one and they sell a radiator to go with it, the end tanks are on top of the core but not modified to fit. Another one that i have found is basiclly similar one to the AZC one, its called Megan racing intercooler. Which should work also, but same thing about the end tanks they need to be modified. Price is about $400 for either one.
I am allmost thinking of getting it custom made but i cant really find anyone to make one that will have 240/260/280z on hand to test fit it.
