That's Ron's Pbase photo site. I about have the table of contents of his gallery memorized now.
Its truly amazing what he has done in terms of contributions to the MR2 community with his photo documentation. Hundreds of photos and many of them took A LOT of time to setup, edit and document, like the ones above. I love how he used blocks to hold up the cooling system and I think you can see someone is standing there in the side holding the heater core, and he used MSPaint or something to blot out the person ... if you look carefully you will see it.
