Why not direct port? From what I've read both wet and dry kits can malfunction leading to total engine loss. However, Direct port kits for only $600-700 more will be much safer on a stock car. If this is true, then I'm thinking $1200 for the kit, $600 for accessories, $400 install and I have a relatively safe daily street driver with an extra 125 shot. Shoot holes in this theory if I'm wrong.

Well, the nice thing about them is that they get a beter mixture to the cylinders. They tend to be used for bigger shots though, most DP kits will tell you the smallest recommended shot is a 150 or so, so it depends on how much you are going to spray.
BTW, you may want to have a mod move this to the nitrous section, may get more opinions over there.

I am doing a 175 now. I really wanted the "look" of the Direct Port.
I had a single nozzle that worked great but looked like every other nitrous setup. The only real advantage of DP is the WOW factor for anything 200 or less; at those levels a single/dual nozzle will do. My friends who are not car guys even freaked when they saw the DP system, but hardly noticed my single nozzle system.
To use a DP on small shots (200 or less) you will probably have to go with a fuel regulator or stand alone fuel system that regulates to 10 PSI. Staying a high PSI with a small shot can (and has) caused problems from the jets being so small. At 60 PSI, for a 150 shot, the jets are .012 (super small) but a 10 PSI, the jets are .020, almost the same size as the nitrous jets at .024 . So be prepared for that added expense and fun of the install. Also be prepared for 1 hour to change jets! Luckily I am at the level I want now.
Good luck.

A directport is a nice way to go.I do not suggest a direct port for anything over a 250 hp shot normally.The directport obviously cost more money but also requires more time and tunning.I would suggest a top quality system like a NX single nozle or maff system.With all the accessories you will have fuun time and time again just as safe.

Agreed 
I'm just as confused as you, but I'm pretty sure it's a typo.

The problem was i read one of the FAQ's which gave a lot of real world drawbacks for the other kits, plus rumors about bad spark plugs, etc. Being a newbie, it seemed simple, pay the extra g, and spray 125-150 shot without worries.

A DP system might be overkill on a stock bottom end depending on how much you want to hit it with. Check my sig for DP pics if you're looking into how they can be done.

i originally bought it to equalize the flow to all the cylinders, trying to help the bottom end last alil bit longer
