FS[NorCal]: Koyo 36mm radiator and GTM fan/shroud
#1
Koyo 36mm radiator and GTM fan/shroud
Price: $750 or best reasonable price; debating on shipping; if I go the shipping route, the price will be $750 + shipping or Best Offer
GTM Fan/Shroud was purchased for $650 plus tax
Koyo 36mm with Sam's customized touches with the GTM Fan/Shroud. The Fans are the 12"/14". Purchaser will have to buy 2 Spal controllers in order to set the high/low temperature settings for the fans to kick on.
This setup was on my 07 G35 Revup coupe with Vortech supercharger for about 2 days, but I ended up going with 56mm radiator with GTM Fan/Shroud. I waited for the 56mm radiator for 2 months and I made the decision to go with the Koyo radiator because I couldn't wait any longer. Then the other radiator became available and decided to go with the larger one.
The Koyo 36mm radiator is currently at ZcarGarage in San Jose, CA. Rob and his crew did the install and there were not any installation problems or clearance. According to Rob at ZcarGarage, the car did cool down to 185F. In the summer months with my Vortech, the coolant temp would easily climb up to 220+. For additional information about the Koyo 36mm radiator/GTM fan/shroud setup, please call Rob at (408) 452-0300. If your in the San Jose area, you can swing by Zcargarage on 140 Archer street and ask Rob to look at the setup.

Let me know if you have any questions about anything? What radiator do you have? I wanted to wait until the end of next week to see what happens with the Radiator/Fan/Shroud. If your interested in the Fan/Shroud, I would be willing to sell it after a week has elapsed.

how do I get the fan shroud to mount o my koyo?? do I have to drill any holes or is this plug and play for me?
#10
it should be plug and play as far as the mechanical install. i can't recall if you'll have to lift up the radiator to mount it at the bottom.
as the OP mentions, you'll need to either get some fan controllers or wire the fans to the factory harness.

Chris currently my setup I have the FAN's wired to the OEM Wiring..they were just spliced...soldered in and so forth...I talked to Steve (OP) on the phone and he had purchased the SPAL FAN RELAY Harness...he mentioned that these were beneficial because he could control when the fans came on...185 and a higher temperature.

he is going to measure the length in between the 2 mounting points and let me know if it works...if it does I will pick it up since this will be the solving problem to my car overheating most likely.

if you've already got the wiring sorted on your end then this would be a good pickup for you man. i've looked at the SPAL controller as well as another one I found through my350z.com...i like the temp control and variable fan speed capabilities they offer, but i'm still running the stock wiring

It looks like you would have to purchase 2 Fan Relay Harness and I will confirm that with Rob as well as with Sam tomorrow.
On the GTM weblink that you provided that contained the Fan Relay Harness, directly below is a photo of the Spal PWM Automatic Programmable Fan Controller which cost $164.95. The Spal PWM Automatic Programmable Fan Controller allows the user to set the temperature at which the fan turns on. The Fan Relay Harness Does Not allow user to set the temperature at which the fan turns on. I wanted to clarify this so that there's no misunderstanding. Also I purchased 2 of the Spal PWM Automatic Programmable Fan Controllers and asked Rob to set the Spal Module temps at 185F for the low temperature setting and 195F for the high temperature setting. Both Fans do turn on when using the A/C.
