Ok, I have my mods in my sig, and just wanna know if i am able to safely spray. I have jets for a 75, 100, and 150. I would really like to spray all the way to 150, but the downside is that i have 161k miles. Yeah, i know, thats a lot. I have a walboro 255lph pump with hotwire kit, TR6 plugs, pulled 2 degrees of timing, with a Dynotune wet kit. Thanks

 

Anyone is going to tell you, was maintenance kept up and so forth? I mean seriously the question you should ask, is "Can I afford to rebuild or replace my engine if something goes wrong?" We all could tell you, get a good tune, make sure maintenance is up to task, and what not, but it takes just one thing to go wrong. Like say...the fuel solenoid craps out or what have you. then boom. It could be anything in your engine on its last legs and the nitrous combustion will find it.

 

150 is going to hurt anything that isn't hurt already.

You pulled 2 degrees of timing from what? A proper tune will help insure that your motor stays together as long as it possibly can.

 

I could save up and replace the motor... i am actually looking for a truck motor for it, but in the meantime i would like to spray to get power. What would be the first thing to let go, or the most likely thing to let go?

 

M6 or an A4? With my set up I purchased a window switch and fuel pressure safety switch. I am an M6 btw.You could go all out with the electronic monitoring (a/f gauge). But a window switch is just some cheap insurance.

 

I have an M6.

 

my friend is spraying his car that has 180k on the motor. It's had a long life and still rapes a lot of cars.
