I would really like to do that, but there is alot of other stuff that has to be replaced and i have no clue what, and how. pluss the big $ factor and also how would the computer mix with that.

How do you know stuff has to be replaced if you dont know what it is?

If you want speed, you have to spend money. Plain and simple no ways around it. Start with exhaust and fuel delivery, then supercharge.

i just know that a stock engine cant handel a big change in power like that, like i know you can put nos on a stock engine but it will probly only last 1 shot and the engine will be toast. I know i gotta spend money but a super charger is like 2500 plus install and other parts. - or at least i think....am i worng? because if a supercharger is all i need and that will do it than thats what i want.

for exhast i was wanting headers and put duals on it with borla. and cutouts right after the headers. will that work with the computer sensers.

What do i need for fuel delevery?

First of all it's "Nitrous Oxide", NOS is a company that makes it. Fuel delivery, like a bigger fuel pump and bigger fuel injectors...Superchargers are generally around +$2,000.

i know its nitrous oxide i just dont want to type that every time i talk about it and would rather use a shorter term that everyone understands.

how big of a fuel pump and how big of injectors do you think would work best?

A nice set of cylinder heads and a good intake system would be a good place to start.

Your engine can handle 8 psi as it is just fine.

that's kind of funny, i could probably toss a good 100 shot of Nitrous at my car before it complains. Hell, the 420a block can withstand 330 hp before I need to really worry. That would mean I could almost toss a 200 shot at it

However I wouldn't do that without other engine work.


Anyways, start with the basics, exhaust system, intake system, and fuel delivery system.

I was going to post more, then realized that i have no information to back up my ideas so...>Jeggs.com< Holley makes exhaust system components (Flowtec line) its pretty cheap stuff and will generaly last a long while.
ATI Procharger is a company that specializes in centrifugal blowers, they're products are pricey, but well worth it (highly efficient blowers w/intercoolers).

Remember...SPEED=MONEY. and be sure to get better tires too.

I like the idea of cylinder heads and a cam and intake and exhaust before i start with superchargers. I also was wondering about getting it stroked. im not to sure how this works yet i think i put a 400 crank in it. (i didnt mean that i did this i just mean i think thats how it would work)

Im just not a big fan of nitrous. plus with my engine with 100K miles on it i think it would go KABOOM!! than VROOM!

I really need some good tires to i just peal out when i take off and always get beat off the line even when im not trying to peal out. i think this is because im not a real great driver and still trying to perfect my clutching.

If you mind me asking what is the 420a block? is it just a 420ci?
