Time for a cooling system refresh - OEM radiator still the way to go?

OE works great on track, just need them back in stock

I've been re-thinking my radiator/oil cooler setup. I'm exploring ways to improve airflow through the coolers, primarily behind the radiator. So far, I'm confident that I can go with a lower capacity radiator and a larger single oil cooler and achieve similar water temps and better oil temps. The problem is ducting air flow out through the hood. If I can push the radiator forward a couple of inches then I'd have enough room.

Try to tilt the front of the radiator forward so it sits more at an angle and build a shroud in back to send air up through the front hood vent. Potentially requires manipulation of hose attachments depending on how steep the angle is.

That’s exactly what I’ve been looking into. Vorshlag built something for one of their LS swaps. I’ve also been looking at something like Chase Bays tucked radiator which is a tad smaller.

But then custom ducting in the front. As Obioban mentioned, I’m a stickler for weight. All of this might add more weight.

I haven't kept up since I've been out for about 6 months, is your car lighter than a Miata these days?

2630 the last time I weighed it - no driver, no fuel.

I've found the Modine on several other sites in stock.

Can you share? Quick google search shows sites out of stock

Seems like several went out of stock. Some of this didn't indicate out of stock, but I'm not 100% sure.

Notably they we're in stock a few months back. Apologize if I teased you.

No worries appreciate you checking, I'll see if the dealer has an ETA.

Dealer said backorder until the end of Feb 2023

I am hunting down a radiator as well. Spoke to someone in dealer parts yesterday who said Germany has approx. 500 radiators in stock. One is headed my way, so orders can be placed / filled now with some certainty. My ETA is 3 weeks.

[CrookedCommie]

Thanks, just talked to dealer, they said same thing, ordered and gave me 10-12 business days to ship from Germany.

As a follow-up, no problems with the fit or operation of the Koyo.

Is it the Modine radiator?

BMW updated the part # - 17 11 5 A7D EF2, not sure if it's a Modine with BMW branding on it, can update when I get it.
