Just wondering if I needed to upgrade my radiator, thermoistat, and have a thermoistat switch in my Type R when I have 11.4.1 compression to run safely and not overheat ? The only other mod that I have is an exhaust...For those of you that have done it properly, please let me know...thanks alot...

 

mugen or spoon caps, and thermostats is suffice
really u just need fuel to keep stuff cool when it comes to compression
ect....

stock is suffice too, but having spoon and/or mugen parts is
cool! especially when its under a 100 bucks

 

Nope, you are fine....the compression isn't going to get the engine to overheat...unless you drive throught death valley at 8000 rpm.
