Take a step back slick. I read your posts. And I know exactly what your thinking of doing. I was your age once as well. I know precisely what goes on in your head. The biggest clue to where your at in your project is you actually care if your car was faster than your friends WRX. Having put so much emphasis on that, I know precisely where your mindset is. So you can lose your high horse. When college starts you will find that you have very little time for toys. Its just not possible to do both well. I think putting your Z to bed for a few years is the smart move, so you can do it when you have A) enough time, and enough money. Because if there is one thing that is universally true, its that college kids lack funds. Your Z will be there waiting for you, by then you may have different priorities, and running in the 11's may not seem like that big a deal. Especially when there will be many people in the 10's. There is always somebody faster. Keep in mind this. It takes A LOT more than just HP to get into the 11's. You are going to have to do a great deal of chassis work and tranny and rear end work if you want to run that hard. 11's is no joke. For every dollar you spend on the engine, be prepared to spend AT LEAST that much if not double on the chassis. Power is meaningless if you cannot get it to the ground. If your still reading and my preaching has not bored you. I only tell you this as I have built up an monster engine or two in my time and chassis tuning is the difference between a 13 second car and a 11 second car.
Also be prepared to only own a drag car. Not too many people have the funds to pull off an 11 second quarter miler and still have a car thats fun to drive and handles well.
Good Luck, but I forsee your goals changing soon. IT may not seem like I am trying to help, but believe me, I am.
