hey wassup n00b. Its pretty easy if you know how to weld or know somebody that does. Take off the pumpkin, open it up, weld the spider gears, fill it back up with diff fluid, and you're good to go.

The SR20DET, KA-T?, and the RB's right? What are the differences? and if i where to put one of these in would i have to put different headers and exhaust on compared to if i put it on the stock engine? also i have a guy that i talked to a little down the street from me and he has 1992 240SX coupe with an RB20DET but he might be upgradeing to an RB25DET and he would sell me his RB20DET for a good price. Would i want to do that or not. Also my dad is able to help me with stuff and he some what knows his way around a car and we have all kinds of tools because he is in construction so i think we could fair all right with some stuff with some instruction. anyways thanks for the help so far guys. and are there any specific intakes, headers, or exhaust that you guys like or is it prtty much anything will do the job?
headers refers to a naturally aspirated engine, its basically the piping that comes off the hot side of the engine and dumps the exhaust flames down piping and out the muffler.
turbo cars on the other hand dont have headers, they have exhaust manifolds where instead of the exhaust fumes coming straight through to the muffler, they instead go through to the turbine first.
http://auto.howstuffworks.com/turbo.htm <-- some decent reading
sr20det is an inline 4 single turbo. rb20det is an inline 6 cylinder single turbo that puts out about the same power, if not a bit more to the wheels. ka-t is your engine, just with a turbo added.
the con about ka-t's is ka are usually high miled, when adding boost, its highly recommended to rebuild. But these torquey engines have a very high potential. If your going with an aftermarket turbo with like a t3 or something, 300rwhp easily can be expected (of course with supporting mods). Also, ka's are dirt cheap. Since everyones hopping on the motorswap bandwagon, you can find really decent ka24de's on the forums for like $300 if not cheaper. so if your engine does blow or throw a rod or something, just toss in a new block, and your good.
rb20s aren't that bad either, they just lack the aftermarket and oem support stateside. If your motor blows or you need certain parts, don't expect to go to your local nissan dealership, ask for a part, and have it at your home on the same day. I dont recall any US cars that have the RB or at least share similar exchangeable parts. Also, iirc, its not a direct swap, you'll need to change the cross member and have custom mounts or something like that.
sr20's is another easy way to get yourself a turbo without having to rebuild or anything. Just make sure you take the head off the engine and carefully inspect it before using it. All that "all JDM engines have only 60,000 miles on it" is bullsh1t. The good thing about it is: its a direct swap (they came in your car's Japanese brother). The only modification you'll need to do is drill a hole near your intake for the side mount intercooler. Everything else just sits perfect. Also, theres HUGE aftermarket support, and internal parts are easy to find because the engine was on US cars (b13 sentra se-r came with a fwd n/a version of the SR20).
just remember theres no such thing as "one is better than the other" because I've met all sorts of people that swear by these engines.
as far as upgrades go... just get the engine you want first, try it out, then we'll talk about upgrades . but just an FYI, your headers are worthless in a turbo car.
