Bimmerforum looking for Pierburg water pump information, was redirected to RealOEM.com which allows extensive cross-referencing.
I pulled the known CWA/BMW part numbers from the TinyCWA website:
https://www.tecomotive.com/en/products/tinycwa.html
I heard back from TCP Performance and griffin radiator.
Basically I asked for information on building a "wide scirocco" radiator. A regular scirocco is a single 18x12 core measuring 22x13 total. Our radiator opening is 28 inches wide, so I asked for information on having one basically widened 6 inches and in a triple core format, ideally three 1 inch cores.
I also went back and forth with Chiseled Performance about a custom intercooler. Bad news bear, there. I'm not impressed with how he presents himself in language, and I kind of get the feeling that he's not interested in contributing to the project.

Thank you for contacting Griffin about a custom radiator.
3 core refers to a copper brass radiator. We build our radiators with 2 row 1.25” tube and 3” thick tank. You would not want to go thicker than that because it will reduce air flow.
We would be happy to build one for you based on your specs. We need you PRINT out our CUSTOM RADIATOR TEMPLATE and fax it in or scan it and email it to me at
[email protected].
Please PRINT IT OUT, fill it out completely, including: Core and tank size (pg1) dimensions, inlet/outlet positions, filler neck, mounting brackets etc. and fax it to my attention at (864) 845-5001 or scan it and email it. My builder will use your drawing so all information needs to be on your drawing.
Custom radiators generally
start at $650 and take 2-3 weeks to build. We will know more once we see your particular application.

We can build that. A 3 row 1" tube core would put the core at 3.5-3.75 then we need an extra .25 front and back for the tanks making them as deep as 4.25. or you can go with a 2 row 1.5" core that will be 3.25 thick making the tanks 3.75. Inlet and outlet on same side not a problem, we will baffle tank and make it a dual pass design which will enhance it's cooling ability by about 15%.
You would be looking at $825 plus shipping. Core thickness would be 3.5 3 row 1" tubes and the tanks would come out to 4".

I would not put two mini coolers, that just going to flow like crap and kill your boost, so 26" from air tube to tube ?, being that all these cores are 24" , that not enough room if going with the 703520-6011, you're kinda limited on space but the nitrous will help with the cooling, we can do the air tubes offset to the btm so the air tanks taper towards the top
>> OK, if they don't have a short core, then 28 can work, I'll just have to use pie cut's for the bends instead of mandrels. "Ugly but functional". Would also like V-band flanges for the connections.
This is the smallest you can make this, you are already small on core size,and air tanks cant be any smaller, can you fit a 4.5" thick core, and 12" tall?
>>4.5 thick won't package well, and would rather not do 12" tall :/
well youre kinda stuck then on this bud
