A blow off valve is what releases pressure when you let off and the throttle blades close. A turbo timer lets the engine idle for an amount of time before shutting it off in order to circulate oil to cool the turbo to avoid damage. You can of course do it yourself by sitting in the car for a minute before you shut it off.

Turbocharging is a much better option in terms of longevity and efficiency. And besides, nitrous will destroy the stock pistons in these engines on the first run...No No No...Not an option...Beside, nitrous is not real horsepower.
As it stands right now, I may be looking at a nice 75 hp increase from the turbo on 4-6 psi of boost which will be apparent through a decent range (2500-4500 rpm's) when compared to nitrous. It will not be as tough on the bottom end and pistons as long as I tune things right.
Nitrous you say? No no no no no!  |
As long as you keep it rich enough, nitrous isn't really going to be any worse for your engine than a turbo that adds comparable power... The transaxle is the more concerning issue anyway and having the ability to run nitrous only when needed instead of a turbo which will produce boost a lot of the time is probably better for it. But you obviously already have the turbo plan in action, so the point is moot. Oh, and nitrous is very real hp according to my in car ass-dyno.
Not real sure what RB is talking about... a wastegate allows exhaust to bypass the turbo to keep it from making over a set amount of boost. At idle it's not gonna be making boost anyway so the wastegate will remain closed.

You my friend, need an extra 193 cubic inches. A 500 will solve that sluggish performance problem pretty well, then spray a 150 shot... oh yeah it'll move pretty good, do mid 13s sound good?
