I've been searching through the forum and have havent seen a clear answer or maybe I've missed it.

Would a Koyo HH030561 Evo 3 radiator fit?

From what I gathered it should but just wanted to know if that specific part # would

If so what should I expect with fitting and how much does it mount up compared to the stock one

I just installed that exact radiator about a month or two ago.

It drops right in (for the most part).

It does not have a bung for the radiator fan switch. I chose to weld one in.

The mounting points for the stock fan line up, but are taller and would require slight modification if wanting to use the stock fan. I ditched the stock fan and installed a Flex-A-Lite 123 puller.

The Koyo radiator felt like it sat a little lower than the stock radiator. I made some shims to lift it up about half an inch.

The radiator overflow hose barb points towards the engine rather than towards the overflow tank on the driver side. (not a big deal)

My ETS intercooler piping - the pipe that runs over the exhaust manifold had a clearance issue with one of the fan mounting points on the top driver's side of the radiator (but we don't have a fan there) so I cut that one off. Problem solved.

Overall, an easy install.

...and I've had no issues with that radiator and the FAL fan driving around out here in the desert on 115+ degree days.

I have a stock DSM fan in my car. Its shorter so I flipped the brackets under the support beam.
