120! Thats really quite hot...!
You dont have to have one with a thermostat, theyre often overpriced and hard to find.
The Just Jap kits are awesome, ive had one with a remote mount for a couple of years now and it does a great job. Street, track, even on a 30 degree day at winton it kept temps reasonable. And even though it doesnt have a thermostat, its doesnt over-cool the oil.
For $460 you cant go wrong.
