Ok heres the deal, Im adding the star performance stage 2 kit, and have the NX mainline kit....my question is what is this motor capable of holding HP wise before I will see problems.....I know its near 300 hp in the lower end, atleast thats what I read online....hopefully one of you will know. If i should wait to run the juice kit what internals should I replace besides the pistons, rings, crank and possibly the cams....or is that it?

I have also pondered the idea of using the N2O kit as a intercooler sprayer and not use it in the motor untill I rip the block apart this winter, better idea?

and my last idea was to jet the N2O kit down to say a 15 shot and put it b4 the intercooler getting the same effect as above only with a shot in the motor causing about a 30hp gain to jump start that massive turbo....

any ideas would be much help, oh yeah hello everyone sorry for sounding like a noob but i am......
 
Basicly if you run the turbo on stock internals, keep the PSI at about 6......and if you use n20, keep it at no more than a 75 shot.....

HOWEVER, using BOTH on a stock motor is not going to be a good idea. Just using n20 in the motor is going to actually raise the turbos pressure to what could be dangerous levels on a stock 420a. I would just go turbo first then get it rebuilt, crank up the pressure then spray after all else is said and done.
 
ok thank you, i kinda figured i would be pushing it too hard if i were to use both on a stock motor.....ill probley install the bottle if i get board but ill make it a point not to fill it untill i get the motor work done.....summer coming so i dont wanna lay it out intill winter.......

as for the juice comment....LOL yeah im pre F + F......they glorified the stuff a little too much......"i got nnooosssssss man" LOL
