I searched didn't find an answer.


I'm currently collecting items to do a NA->t conversion. Today, my friend was looking at all my stuff and said I should bolt the turbo (12 fin) fan up to my engine now while I wait to get the other stuff I need. I'm driving the car now to and from work but when I get everything in, she will be going under the knife. Will there be any cooling advantages to using a 12 fin fan on my N/A engine?

The engineers thought so. But the turbo also has a different viscous coupling.

Bingo. Exact reason why I bought my fan clutch from the dealer becasue the parts stores had one part number for both...

I swear, I'm putting this in my sig one day: It would have been cheaper to do it the other way, so there was obviously a GOOD reason that they changed it.

NA Coupling is Blue, GTE is Orange/Brown, there's a HUGE difference in the case size and fluid capacity.

I think, I don't know, that engines with a W series trans gets one clutch, and the R series trans gets another, including trucks.

I'm afraid I don't understand. Could you explain?

7 blade fan goes on the fan clutch with the blue shaft

10 blade fan goes on the fan clutch with the orange shaft.

The 2 clutches are totally different due to the load the 10 blade fan puts on them, the smaller one won't work correctly with the 10 blade fan as it will slip constantly.
