i was planning on doing a SR20DET swap on a S14 240SX...what are some things i should look out for when doing this swap..will it pass emmissions, state laws, etc...are they reliable engines? how hard is it to do the swap...would it matter if they have don it before? also if i have problems with my engine, how will i fix it if i cant take it to the dealer?would i go to the same person who put it in for me? i live in memphis, TN so not alot of people around here know alot about these engines but a few people..give me your opinions/advice on the emmissions/ instal/problems/reliability...etc
thanx

AS far as I know there is absolutely no realistic way to make the engine legal in the states in an american 240. the deartment of transportation (DOT) never certified the engine, because there are not widely imported nissans with that engine in them. And when you import a new engine (one never before tested), DOT has to rune 50 grand in tests on it. That is the only way to make if comepletely legal. The engine will pass oregons smog test though. They have pretty strict regulations in japan where the SR's come from. You can still get tags ans a plate sometimes though. You just have to lucky and have the visual inspection overlooked. (it happened once before when i ahd a suzuki samurai) THe other way to get it overlooked is to pay to have it done. (This is different than a bribe, wink wink)
      The reason why RB26DETT's get legalized is because they are in the original chassis the egine was put in. But ours come out and into another chassis. Still, legalizing a Skyline is prety damn expensive, aspecially a new one.
      As far as i know, the engineis very reliable. As soon as the guys at SCC got their's running, they set out for a 400 mile road trip. And their chassis had 270,000 miles on it! So I Would say go for it. Getting it "illegally" legalized shouldn't be that hard. Thats how everyone I know of does it in california... Someone let me know if any my info is off.

I put a post a while back to give some of the ins and outs of having an SR swap I will give you a quick run down of what is needed from you

1. evaluate your ride make sure it is worthy to put 50hp or more in it (check motor mounts, brakes, radiator, etc.) If anything is not in order fix it before....I repeat before you put the SR in Don't just worry about it later because you may blow up your engine or wreck your ride you dumped all that money in

2. get a haynes or chilton for the 240 and a FSM for the SR because unless you are made of money it is expensive to take the Sr to a specialty shop to do the work and they probally know less about it than you

3. Invest in some good tools and multiple sets of ratchets and such

4. The first month is when all the bugs come to light (coolant leaks, bad gaskets, oil leaks, weird noises)  So be prepared for some additional work after you get the SR fired up.

5. Like you said you will not be able to take your car to Nissan anymore (they won't touch it w/ a 10ft pole)

6. After all bugs are worked out that is the best time to start upgrading (fmic, boost controller, dp, etc) The reason why I say get the bugs worked out first is so if there is something wrong w/ the SR you know its the engine and not the upgrades. It just make trouble shooting that much easier

Just my .02 take it for what it is.  Everything that I wrote about is from my 1 install and from civic killas experience w/ his 2 SR installs
