This is something that's crossed my mind with all of the available oil cooler options: it doesn't seem like any of them are going to be compatible with a good-sized intercooler for super/turbo-charger applications. My guess is people who put on intercoolers are going to end up just moving their oil/trans/ps coolers smack up against the radiator and finding new ways to fasten them in place.

There is plenty of room between the AC condenser and the IC. As long as you do your oil cooler similar to the way its mounted on the NISMO car, you'll be fine. There isn't any room in front of the IC w/ out hacking up the bumper cover though, the IC sits pretty much flush w/ front end.

here's a retarded question, but it was bound to happen. Does the NISMO version in fact come with an oil cooler?

no.

Which NISMO car are you talking about?

I don't think so. The NISMO car doesn't come with an oil cooler btw. The official NISMO oil cooler mounts similarly to the Stillen, but it's taller (and may be set back some). The Stillen one mounts with a good gap between it and the radiator, and relocates the PS cooler back there between the two (and I assume their upgraded PS cooler goes in the same spot). Point being, there's not enough room in any of the gaps (radiator -> PS cooler, PS cooler -> oil cooler, oil cooler -> bumper) to fit the thickness of most intercoolers I've seen. Perhaps their plan will be to fit exactly two coolers up close to the radiator (one on each side) with the IC up in front of them. May work for 6MT (oil + PS coolers), but not 7AT (which also could use an AT cooler).
