Hello, new here, question about Az Heat

[spdbrake]

The BDR comes standard with the OEM BMW E36 (325i) radiator. (1 row)
The alum fan shroud and 16" 2200cfm fan are fine as is.
You can upgrade to an 2 row aluminum 30% increased capacity either thru Backdraft. (Iconic parts)

Mishimoto MMRAD-E36-92 30% more capacity

Mishimoto also makes an even thicker radiator thats 91% more capacity than the stock E36.

Also you may take a look at your crank pulley dia. most kits come with the "Performance" underdrive pulley to give a whole 6 more HP and switch to the OEM dia pulley to give you more GPM especially at idle. Very helpful in traffic.
On mine I switched from.

Last thing. If your car is an RT4 I'd call Backdraft and question them on radiator to see if it has changed from the RT3. So far I only know of drivetrain and suspension changes on the RT4.
