Newb looking for more power on SR20DET

[AndrewM]

Im a newb, but not new to forums. Ive searched and haven't found what Im looking for. I can harass newbs with the best of em for asking dumb questions like Im about to ask, so please keep it to a minimum

Im looking to get around 275rwhp - 300rwhp. I need to know the basics for getting more power out of my redtop. I have a basically stock sr20det with nice front mount intercooler and a Walbro 255 fuel pump. Thats about it. I want to know:

1. I know i need a better turbo for more power, so Im thinking GT2871R.

2. With a new turbo, how much power can I make until the stock injectors are maxed out?

3. I have a KA MAF, what should that be replaced with and at what power level is that necessary?

4. What is the "best"(read cheapest way that works good) thing to control the bigger injectors?

5. Do people have success with piggybacks on the sr20? Like an E-manage, SMT7, etc...?

Any other comments to help me know what I need to get that kind of power. Thanks. Also, if there is already a badass writeup that already goes over all this, just please post the link. Thank you.
