how much n2o is safe on a stock bottom end?

 

You must also be the kind of person who only wears designer clothes...

 

Ok listen, if you play your cards right i have seen 185 shot... most people blow at 150 or tell you not to go to 150. Its all in the tune. If you have a great tune, the proper fuel, you can go over 150 or even 150 if you want.

 

that brings me into another question how much does a good tune usually coast?

 

tunes vary on the tuner, the shop, and how well you want it done. If you want a good tune, i would suspect...including dyno time...around 250-300 if not a little more. I would pay out the butt for a great tune because you make an investment...you better be one, getting the full benefit from it and two, not having to worry about the investment causing more money stealing problems. so go for the best you can find. no matter how much it is.

 

yeah how about cams im gunna run p.i. heads i think and get them ported but what cams would be best for nitrous?.... if u cant tell this is a major first for me first mod motor, first fuel injected, and first nitrous build lol

 

Call Cushman motorsports up and just ask them. they can custom grind you cams that will be perfect for your nitrous/NA setup. Im sure of it. A lot of people on here like their stuff so thats why i say use them. Id say consider looking into this deal...

Patriot stage 2 heads and Cushman cams already assembled for $1895. And with those i would suggest that you go with Cushman stage 2 cams.

 

would that setup up my compression i have a npi motor

 

yes it would. Any pi head is going to up your compression and thats good for nitrous too. You will be somewhere between 10-10.5 with any pi heads if im not mistaken.

 

this maybe a stupid question but how much more of a gain would i have with the patriot stage 2 heads over a ported p.i. head?
