I usually try to avoid posts like this, but I'm at a loss here for comprehension, so here's my take on this. Your post reads as follows:

"i just got my dream car 1996 240sx se it bone stock but i have big plans for it.but i dont know if i should change the internals on my stock 2.4 engine or go for the swap sr20det. some of my worries that if i change all my internals will i have problems down the road with the block....? and will i be able 2 get 450+hp with turbo out of my stock block with no problems....? any one who can help......"


You've just purchased your dream car, congratulations. Now put down the issue of ImPoRt TuNeR, wipe the spew off yourself, and pay attention.
If the car is your 'dream car', why do you not even know what the engine code is? I bought my first 240 in 1995, but I already knew everything about it long before then. I'd say some forum members (the intelligent 4%) would also agree that if you've actually dreamed of owning this car you'd have a clue about it. You don't, so I call BS on that. If your dream is inspired by cool pictures in magazines that you jack off to in the bathroom and the 240 was the main one that caught your eye then say so. No need to impress anyone here, you're new, uneducated, and so far ignorant as hell.
Now, you're 16 yrs old. That's a strike two, because you've just gotten behind the wheel of a RWD car and have about as much driver training as a chickpea. Your main goal here is to achieve 450whp, that's strike three, because not only are you young and ignorant but now you've proven to be dangerous, you're going to surely kill yourself and possibly other people with that kind of power. 450whp in a 240SX is simply too much for any kind of regular driving, and even a lot for most sporting events. You don't seem interested in any of that or you would have thrown in suspension and braking concerns, so we'll assume you just want to impress the kids at your school. That's stupid.

Buy an FSM, study it and learn the car. Replace everything that needs it first to get it back to it's OE condition. That means tension rod bushings, tie rod ends, the front crank seal, rear main seal, the massive leak you surely have around the oilpan, bleed the brakes, check for seized calipers and untrue/warped rotors, all the things the car is definitely in need of. And believe me it needs all that and more. Then do a compression test, change the oil, etc and get a feel for the car in it's like new condition. Then go drive it, for a year, under careful conditions, not like an idiot that you kids seem to be behind the wheel of any car. Sign up for a few driving classes, learn car control, get with your local SCCA and do some closed course driving. Then hook up with one of the members here or locally to you that's a skilled driver and has 275-300whp and go for a ride. Then come back and tell us if you feel competent enough to handle your goal of 450whp.

If you think that's harsh, then go ahead with your plan. No one will care when you wrap it around a tree and kill yourself.
