    im using stock E36 m3 radiator in my S50B30 swap. paired with spal fan i have no heating issues....although mine is not a track car like yours.

    i suggest also have a look on r3vlimited forum in their engine swap section if you dont find much help here..

        I would check European S54 swaps. I think they use the e36 M3 3.2 radiator. It is not as tall as the US rad, yet has better cooling capacity

          I have been researching the same question. I am to the point that I need to purchase a radiator for my race car, but I want to make sure that it has enough cooling for the S54 on the track. I'm probably leaning towards some kind of aftermarket option if there is one. There sure isn't a lot of clearance!

            I have never really looked into it, but can't you fit an e46 M3 rad and bolt the fan in front of the rad in pusher mod?

              PWR is the goods, race version. Bimmerworld runs it on their swaps. I wouldn't go with anything less. Good luck.

                PWR is what I want to go with. Lee, my car has a pusher fan. I just don't see how you can really fit anything in there without moving the fan to in front of the radiator. In saying that, I don't have the motor moved back at all with a modified firewall. Obviously that gives you lots of options.

                  the best radiator to use is from the m-coupe z3 with the s54, it's longer than the e36 n the e46 s54, n use the m-coupe upper n lower hoses has clearance for the a/c compressor too, has the temp sensor on the side for the aux fan, i use the temp sensor form a 96 318i it comes in at 88/80 deg cel, u can switch the wires around, this works for me using the original aux fan for cooling no problem so far even with the hot day we been having in new york, even in traffic i'm ok,

                    I've had a few. I now have a Ford roundy round triple pass radiator for $199. However the key point is getting the air to the radiator more so than the actual radiator. I have an extra hole in the main part of the bumper (in addition to the stock lower opening). I put some mesh over it to protect the rad, but at COTA we removed it to reduce operating temps. Will not change anything on the next motor.

                      next motor? You going to have Bob help you GMW your BMW? What is the thickness of that Ford radiator or can you give me some info on it's dimensions and where to get it? Knowing you've got it working on your race car is promising! The thought of cutting up my front end to get more air flow doesn't have me too excited, though.

                        No LS, if I were to do that I'd buy Bobs car.

                        I thought it was a Ford but it is a Chevy. I think I have a 26 or 28. http://daymotorsports.com/proddisp.p...vere+overheati

                            I've a PWR, but if you want more for the money I'd also say Chevy rad. I have a few generics and a Ron Davis version. Way more cooling cores and easier on the wallet. Can even have some shops (Ron Davis) to put smaller inlets/outlets i configurations you need.

                              What about a $200 Mishimoto e36 rad?
