Yes you can get them built in...i have one for my G35 but I have a manual so no need for it here.

Fits fine in my g35 coupe...execept the fan shrouds have to be cut away a little for the charge pipes routing to the intercooler. The radiator itself fits fine...

Then they changed it. I can't remember who, but someone had one over a year ago and he said it was a PITA to install and required mods.

Vinh (drsifu) posted bad fitment. I think it was wrong pitch on the threads.

I've heard from someone that helped install a Mishimoto that it fit like turd, didn't come with fittings for the AT compartment.

good post copied from my350z.com:

compared to the stock radiator:

some close ups of the welds:





Here you can see another small touch where the craftsmanship is not up to koyo standards - the radiator fill neck is not welded on so the barb that the overflow hose connects to is parallel with the rest of the radiator. Big deal? No, but something that may bother some people.


My overall impression is that it is a nice piece for the cost. For perspective, I paid $200 shipped for this. That is just slightly more then half the cost of a Koyo V core (36mm) shipped to me. It will clearly increase both coolant capacity and cooling capability over the pathetic OEM radiator. If you are a brand *****, or aesthetic imperfections bother you, then you should skip the mishimoto and pay the premium for a Koyo. I am a function over form guy for the most part, so I am happy with this purchase. I cannot comment on fit yet because my car is still completely torn apart, but all the mounting tabs and brackets lined up with the same points on the OEM radiator.

^^^ those welds arent too bad... but that is a 350Z rad right? So the G35 isnt going to be as much bigger over OEM (but still bigger nonetheless)...

welds on the koyo are a little tighter & cleaner, especially around the mounting studs and inlet/outlet. koyo & mishimoto g35 radiators are larger than the stock radiator.

All the oems are the same size thickness. Aftermarkets usually come in a double or triple thick core. The Z thread is a double thickness core.

G35 triple thick core on the left 350z double thick core on the right. You can tell by the location of the radiator cap which one is which.

^^^ thanks for the clarification... I was thinking the size was the other way around in post 34... but yes, the fill hole is an identifier I should have paid more attention to.

So is this to say either can be had as double or triple thick core? I’m surprised the G would be bigger than Z – unless its an option for either… or is there more room in the G for a thicker core?

The G has a little more room, not by much though. The PWR only comes in one size, mishimoto may come in 2 sizes.
