I was hoping I could get some help on this. I was wondering why do they only make the 36mm radiators for the HR and they make the 36mm(v core) and the 53mm(r core) for the de. Is it due to a different design where it is unnecessary or does it not fit?

 

anyone have any input on this?

 

I've wondered the same thing, to my understanding its not needed. Heard from a few shops that best be radiator is oem for the hr

 

Because no one like us HR guys.

 

Seems to be so.

 

Maybe its me but that doesn't make sense. The bigger the radiator the more coolant can flow through...idk. I know a local shop that makes custom radiators and I was thinking of seeing how much they would charge to make a 53mm

 

what the name of the shop? Im interested also.

 

I don't remember the shops name off hand, but I not at a rush to get this started because my warranty isn't up til april. I'm just trying to get some info together before I attempt this.

 

It's because the R-core doesn't fit without heavy modifications. I've had a DE Koyo R-core in my 07 for over 2 years. The rad required cut/weld fabrication of coarse, as well as serious modifications to the fans and fan shroud, overflow tank, and front support to squeeze it all in with the A/C condenser.

 

Is that the oem fan housing? Also what thermostat so you have?

 

^that is one heck of a custom fit job, def gna stick with OEM now...
