Cooler coolant thermostat?

[MatRacer]

I'm doing a overhaul on my S50. It will go in my E30...

I was thinking to go with a bimmerworld 71degC thermostat. Is there any downside to this mod?

Thanks!

Your heat may suck.

We usually stick with 80C.

[MatRacer]

Original is 88 or 92degC... So I should go with a 80?

Whats the p/n for the 80C?

[Danny]

I use the 80.

The 80*C thermostat is the e30 M20 stock thermostat.

[dude8383]

Oh werd? I didn't know the M20 one fits (coming from m42 here cut me some slack).

cars run better with the 80. only use the 88 or 92 if you get emissions checked. cheers, jason

I wont get emission checked. I will go with a 80C.

the part # would be: 11-53-1-466-174-80

According to the seal diameter, it would fit the S50
