Can an OEM RB25DET thermostat, work with an RB20DET motor?
Or should i just stick with the low temp Nismo brand?

they are both the same....only the RB26 is different

Why would you think the RB25 would be any different?

if you want cooler temps get a Nismo

yeah i would like to stay away from higher temps.
Nismo it is.

a koyo/mishimoto radiator helps alot too.
a lower thermo doesnt help much when you have a crappy radiator

Yep i do have a Mishimoto rad by the way.
I just want to manage my temps on that motor.
