I'm about to get the NOS 5177 kit and runnin about 100-125 shot with the mods in my sig. Do i need to update anything (fuel pump, etc) or can the stock fuel pump, etc. handle 100-125 shot.

 

I would add a fuel pump, and depending on how much you spray, larger fuel injectors (and a new tune for them). If you're thinking of a 125 shot or higher you might want to consider a wet kit. We're have a 15% off dry kits and 10% off wet kits now. If you have any other questions let us know.

 

Honestly, the highest i'll probably go is 100 shot. How do you add a fuel pump? Also do i really need new injectors for 100 shot?

Also how much $ would a fuel pump cost and how hard is it to install? Sorry for the ignorance, i'm learnin!!

 

Do you know what your RWHP is? You're right on the borderline for the larger injectors.

I would look at a Racetronix fuel system. They are pretty easy to install, and you have two ways of doing it. One is to drop the tank (harder way). The other is to cut a hole through the body above the gas tank. Then you can just pull the pump up. It's not as bad as it sounds, a lot of guys don't like to hear about cutting up there cars. There are a few good resources on the internet for doing it that way.

 

So if i went with a wet kit would i have to change all of that?? I really would like to avoid having to either pull my gas tank off or cut a hole in my car. Thanks for the replys.

I'm around 400rwhp right now.

 

You would not need the injectors (or tune) with the wet kit. People have been successful with your mods spraying a 100 shot, just as other people have not. I would do a fuel pump if it was my car. Another idea might be to install a wet kit and spray it on a dyno for the first time. Watch your A/F with the wideband while watching the fuel pressure. That should give you a pretty good idea. A fuel pressure saftey switch would help too.
