I decided not to bother with the 5177 dry kit.. I'm going to pick up a wet conversion from Dynotune..

Do I need to purchase a new Nitrous Solenoid, or are the solenoids that come with the 5177 kit sufficient?

 

I believe that the NOS Powershot noids are only rated for a 175hp shot. Most guys that run the 5177 with drilled out jets see about 140-150rwhp gain so I would say that's about right. If you have the money I would buy a new nitrous noid then sell the front half of the 5177 kit. That's what I did, I was able to make enough money for a new lid and some parts for the conversion (old lid went with the 5177).

 

If your converting to a wet from the 5177 you will need to buy 1 powershot (type) fuel solinoid. You will aslo need a wet nozzle and a -4 fuel line to go from the fuel rail to the fuel noid and the a -3 line to go from the fuel noid to the nozzle. You will also need fuel jets. Call Dynotune or Nitro Dave and they will hook you up.

Your other option is to reroute the 5177 kit a bit. With the addition of 1 -3 to 1/8 npt fitting...you can spray up to a 200 dry.

 

Thanks alot for the heads up...
Its actually cheaper to convert to wet... then to buy bigger injectors to support the 5177 kit..
