Any progress on V8 engine swap options?

FWIW, there's a guy named bisi ezerioha that did what was probably the first twin turbo 986 build. His turbos were remote mounted (where OEM muffler would be) and intake was plumbed into the trunk, where a large a2w intercooler setup was mounted with the heat exchanger being the front 3rd radiator. I've not gotten to talk to him directly about his experience but in an interview with Hoonigan, he said his setup resulted in IAT that never exceeded ambient temps on hard track days.

So you’re saying it’s possible to have stable IATs! Is this build documented anywhere?

There is/was also a Subaru powered Boxster out there that started with a pretty trick a2a in the trunk but ended up with a a2w in the trunk. See the link below. This guy also (I believe) simply repurposed the 3rd radiator for intercooling. That would be great and easy, but I would worry that engine cooling would be inadequate. Anyone have any thoughts or experience regarding only using the side radiators for the 2.7t engine and using the 3rd for intercooling?

The standard 3rd radiator doesn't look a good design in terms of cooling for a charge cooler. No issue with just the side radiators, that's what I use (with a/c condensers in front of them), ever had issues with engine coolant temperature, even on the dyno.

He's a nice guy and he builds cool stuff. He's only running small boost (<10psi?), I don't think his system has as much demand on it as mine does. Also, the car is a tool to promote his business, not convinced he'd say it performed like **************** even if it did.

The simple fact with all charge cooler systems I've seen is they work well for a short period but eventually you heat the coolant up and it won't come back down until you are off the throttle. That includes manufacturers with proper development. All the improvements (larger radiators, better pumps, more capacity, etc) just move the window a bit. That's the way I see them anyway.
