is direct port nitrous injection too much for a stock motor?

 

Depends on the shot your using..

 

I agree. On a stock motor I would run a wet system so you have a fuel solenoid that comes with the nitrous system to deliver the extra fuel needed. Don't do dry unless you replace your injectors with higher flow injectors because your stock injectors will be running at a high duty cycle and fail. You don't want anything over a 50% increase in total power on a stock motor or you will kill it. There's no need for direct port on a stock motor. It's too complicated to install anyway.

The dry kits dont increase duty cycle, they bump up the fuel pressure to flow more fuel.. Dry kits are fine for small amounts of nitrous(55,65,75) but I wouldnt go any more than that..
