Ok, after all the new SEARCHING that i have done , i only have 3 things not covered.............................. 1) For the new vortech available, which one is better v1 or v2 other than sound , and which trim is better, Si or T....................... 2) Which injectors will work best with about 12 psi S/c , i have come up with either 370cc or 550cc injectors, which one is better and easier to install, and if there is anyone better please tell me about it, and finally if i chose 370cc for example can it come from "Rc fuel injectors" as sold from ebay, or from a 300zx?............................ 3) finally, will the 01 pathfinder TB with Z32 MAF work as the best simplest combo, and as i read, i dont need an upgraded ECU for it, will anything else be better?................................ people please help me with this and i wont ever bother you again, i really appretiate it
well, i actually want to do it with my crew, because this will help me learn a lot so when im in my 20s i can do this to my future cars easily =] nd somone please answer my last question up there

I doubt you'll get that much help, because your post is indicative of someone who hasn't done much research. The questions you are asking are Forced Induction 101, and you are going to run into some MUCH tougher issues once you begin the install. As an example, the differences between the Vortech blowers has been discussed repeatedly on this forum ever since the original Stillen kit hit the market. Also, asking about the size injectors you will need in terms of ease of installation is absurd; they look exactly the same, and will install exactly the same. A more advanced question might be, "Approximately what duty cycle will 370cc injectors be running at redline with 13psi of boost at a 34psi base fuel pressure?"

man that was good but look, i really tried my best looking for all that, and all i end up with is reading 4 page threads to just explain a mini detail in all my category, because now i am starting to get a grasp of everything that i need to get the best results, after i understand how everything will work at its best exactly, i will start looking into really more advanced stuff. for example, first i start looking for an intercooler, then i wanted to decide between an air to air intercooler and an air to water aftercooler, i asked people for opinions, and after i understood what both do, i now know everything in detail about both of them, and i know which one i will be getting and why, and even how to fix the leak if it ever happens in the intercooler! so please just explain in a sentance or 2 each of my 3 questions so that i can know where to head from your choices. =]
oh and btw, i covered this before and the guy above you explained it. for the s/c part, it has not been covered at all because all that has been covered is the old V1 S trim and that was in 2002 because thats when everyone got into them. but the new Si and T trim have just been out for like 2 years IIRC so there is almost no information covering which one will work best...

That's what research is, man. The answers aren't going to magically appear on a silver platter; sometimes you have to do some digging to get what you want. Besides that, a lot of the basic concepts are universal in their application. Looking at other websites, or just using plain ol' Google, can help.
Here are some answers (or questions, which you should be able to answer):
#2: What is the purpose of upgrading injectors for your application, and why can't you use a simple FMU for the amount of boost you're trying to run? What engine management system are you planning on using? (This isn't rhetorical)
nd why wont i upgrade injectors???? im going to supercharge and most likely run 2.62" or 2.87" .... so this would be in my advantage and its very cheap. same thing goes with TB and MAF, they are better, and i can get them for very cheap

You don't understand: I'm asking you a technical question to assess your knowledge of fuel delivery basics.
To reiterate: why is in necessary to run larger injectors with a high level of boost? What is the purpose of the FMU in the Stillen kit? Why is the Z32 MAF popular for higher-horsepower applications?
Find the answers to these questions, answer them fully here, and maybe I'll answer some of your others.
ok so what i found out is that because of the FMU, i dont need to get injectors because it will neutralize the oil pressure to prevent detotnation. ok so if that is true, then why do some people still change to bigger injectors ?

You are misunderstanding the role of the FMU. It doesn't "neutralize" anything, especially oil pressure... which has nothing to do with combustion characteristics. It does, however, alter fuel pressure.
If you answer the question "why would you want to alter the fuel pressure?", you'll also answer your question regarding the bigger injectors.

Some of your questions don't even make any sense, like "which injectors are better and easier to install.....370's or 550's??"
What kind of question is that?? You install the correct sized injector based on your application/goal. Also, a 370cc injector installs the same as a 550cc injector....
Do you even know if you need top feed or side feed injectors??? (I do)
LOL at knowing everything there is to know about air cooled intercoolers vs. water cooled aftercoolers.
You can't cram force induction into 1 hour of searching and reading OP...that's what it appears you are trying to do IMO. Sloooooooooow it down. Buy "Supercharged" from Amazon and read it 3 times. This will give you a good understanding of supercharging and all the related componenents.

=/ man whats so hard about telling me if 370cc or 550cc is better for my 420whp goal?
Here's what's so hard:
You are so, so obviously way in over your head.
First, you don't seem to have even the most cursory understanding of how forced induction (or fuel delivery in general, for that matter) works on an internal combustion engine. You'd been told repeatedly to step back, learn a few basic things, answer a few EASY questions (which you have not yet done, even though the test is open book), and come back when you have some issues or questions that haven't already been addressed dozens of times. Virtually everything you've asked can be answered in the STICKIES OF THIS FORUM. How difficult is that?
Second, you seem to have an entitlement complex that the information you desire should just be forked over to you for free. Listen, you gotta pay to play. The folks here aren't charging you money, but they are going to ask that you at least come to the table with some basic knowledge. Saying that an FMU somehow "neutralizes oil pressure" is so absurd, I might use it as a signature. If you don't respect the already ample supply of hard earned knowledge available, why should anyone respect your questions?
Third, I have no idea what "=/" means. I assume it means "I have completely ignored your posts and insist on re-asking stupid questions."

Too late
But I agree with every single point you've made.
