What's goin on fellas? I'm pretty new to this whole car enthusiast thing so the following question may sound extremely dumb to most of you out there. I drive a stock Nissan 200sx (not sport edition). I was wondering if it were possible to upgrade the stock engine in it to the same one in a 240sx with turbo. Also, will i still be able to run nitrous and turbo without too much modification? (other than dropping in a whole new engine of course- oh and a 9 inch K&N air filter made for a 5.0)

anything is possible , but there would be a lot of modifying in order to do this. if you are looking for a srde block i have a bare one i would let go cheap!

There's a FWD version of the same engine, the SR20DET that is quite available for import from Japan.

Other ideas would be to buy a late USDM SR20DE and turbo it, there are lots of kits available. Or you could import a Japanese SR20VE and turbo it, even.

However, putting in one straight from a 240 would be hard because it is oriented the wrong way (longitudal, rather than transverse) and has a RWD tranny (which is not simply swappable with a FWD).

Meaning, you'd have to make a driveshaft (eek-$!) and wiring harness and God knows what else.

Is your 200SX a B14 or an older S11/S12?

The B14 is FWD and could easily swap an SR20DE from a 95-99 200SX SE-R or 98-99 Sentra SE (B14s), a classic 91-94 SE-R (B13), a 00-01 Sentra SE (B15) or almost any Infiniti G20. Or you could go JDM with a turbo/intercooled engine from a Bluebird, Almera, Sunny GTi or something similar.

The S11/S12 is RWD and while motor mounts and things might work to swap a KA24DE or a JDM SR20DET from a Silvia, I think the older chassis used carburation in their original drivetrains. So there would be some work upgrading the fuel system.
