The easiest engine swaps for a 240sx would be an sr20det or a ca18det as these require no modification to the motor mount location.
No none of the us 240sx have a stock turbo only imported engines do like the ca18det, sr20det, and the rb20det.
CA18DET has a timing belt SR20DET has a timing chain 1993 UK car (S13) will be a CA18 DET
The easiest conversion will be the jdm sr20det swap or the ca18det. If you want a little bit more power there's always the Rb series motors for the skylines or the 2jzgte on supras and if you want to go all out the ls motor from Chevy Corvette is the best conversion, depending on the time and money you want to put down.
Sr20de or the sr20det /or/ CA18de/ CA18det both come as a turbo and non turbo. 1.8 is a direct fit the sr20 will need conversion mounts etc...
Depending on which Altima and which SR20DET you're referring to. S13 SR20DET=205 hp S14 SR20DET=220 hp S15 SR20DET=247 hp
