Supercharging the Nissan VQ35DE with Vortech!


The Koyo radiator is a lot thicker than the stock radiator and we were sure that the compressor discharge pipe would not bolt in due to interference.
So try as we might, the compressor discharge pipe would not fit.
We had to cut away the fan shroud to make room.
Next we had to grind on one of the plastic arms of the radiator fan mount.
Finally, we had to cut and reclock the pipe.  We also had to flatten it very slightly in one spot.
Howard rewelds the pipe after modifying it. If you decided to keep the stock radiator, none of this is necessary. When researching things, the Koyo was the thinnest high performance radiator we could find and there is not a milimeter to spare so we might go as far as to say the Koyo is the only radiator that will fit without major fabrication or switching to super thin aftermarket fans which usually don’t work as well as the OEM ones unless you make a custom shroud.


  1. This was the best G35 Supercharge article. I wish you had a YouTube video channel.

    Out of curiosity. I have a 2003 G35 Auto. If I supercharged my car (as it’s an auto transmission), do you think that I would have any issues with the rev limiter?

  2. I know this is a crazy question, but I have a 2001 Nissan Pathfinder with the same engine in it that I would love to give more power and a supercharger would be perfect as it would also help with the normal power loss of running a NA engine at altitude (I live in Colorado between 6000-9500 ft) would this kit work on a Pathfinder? Is it available? Do you know of anyone who could do this install? Thanks! Tim
