Supercharging the Nissan VQ35DE with Vortech!


The radiator comes with a 1.3 bar or 19 psi high pressure cap.  The stock radiator cap is rated at 0.9 bar. By increasing the cap pressure the boiling point of the coolant is increased to around 268 degrees or 56 degrees higher than the normal boiling point of water. Internal boiling reduces cooling efficiency by hampering heat transfer so raising the boiling point is a good thing.
To install the Vortech kit we first had to remove the radiator.  The fit of everything is super tight near the front of the car and removing all of this stuff makes the kit installation much simpler.
Next the belly pan and front fascia were removed.
Now we have full access to the front of the engine.
The blower mounting bracket and intermediate shaft were pre assembled.
Next the bracket was installed on the front of the engine using existing bolt holes with new bolts.  The new front drive belt was installed and tensioned.


  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
