i was running e28 535i radiator on my s38 car but it didn't get enough ariflow at idle to cool the engine and temperature would start to creep up. I have not found a solution I like yet

I have a other e30 with s38 (m88/3) it has a e28 m5 radiator. The only difference between e28 535i and m5 radiator are the tanks on out lit nipples. On the black e30 s38 had cooling problems in the beginning. I had to two 10” more fan as pullers. In of the radiator is a factory AC fan. I drilled two more holes into Thermostat to flow more water. I’m using a lower thermostat. It keep temps down for 23 years with not problems.
I’m going to be doing the same on this build.

Lower Tstat with adjustable fan controller?

I put the lowest one. I drilled two hole into thermostat to allow more flow. I have factory ac fan on low and high speed plus two 10” puller fans. At 112 degrees it keeps temps down on my blk s38 m3.

I tacked my tips on my muffler. I am still thinking about oval tip like Hartge.
I am also wiring rear fog lights and switch.

I’m finished on rear fog lights. I need to replace rear back euro back panels with better ones. I’m having problems with front passenger side headlight. It seems I have a short in wiring. I checked wiring for breaks. No luck. I ordered a electoral short tester.

I ordered a oxygen sensor. I welded the bun on the down pipe.

I was thinking about my Hartge 280km cluster. I did not want to pull speedo out to put in my m3 cluster.

I ordered a custom Hartge 300km m3 cluster with digital
gauges. I the fuel gauge changed to 55 liters. Sorry about the pics not in order.

Thanks, Sam.

I have more cool things coming soon.
I was having trouble with HID light on passenger. It would flicker on and off. I found it was a bad ground in the wiring. It works now.
I received my two Spal 10” fans today. I will be running three Spal fans.

I agree with you. I just need to figure witch one that will look a a Hartge tip.

I worked on all three of my fans to fit in a tight space. I made some aluminum tabs and drilled them to allow air to flow radiator.

I had to adjust the pusher fan to be flush on radiator. I noticed when I ran power to it the air was not pushing all the air threw. It had a gap around a 1/4”. It is not bolted on radiator. It bolted on core support that is not perfect.

I think the S Blade version has a higher cfm. And if it’s a spal, they have fan gaskets to help seal the radiator.

Running AC? What are you going to do for a controller?

Thank you for input.

I didn’t know spal had a gasket. I managed to get fan up to radiator. It pushes three now.

No AC for now.🥵

I received this today.
