Im researching on doing a sr20det swap in a sentra (b13). I was wondering if there is a specific model (example: se, xe, se-r,etc) tat i need in order for the sr20det to fit? Or can it fit in all the models.

it can fit in all the models. tell ya what, since your somewhat local, come down to the meet in chicago on the 26th. you will see plenty of swapped b13s there :).

but to answer your question, you can do it into any model. here is a thread of information that is more than enough:

okay thanks alot i researched but there wasn't really anything out there that told you straight up that you can do it in any model. Thanks.

any model that came with a 2L sr20de makes it an easy swap. Any car that comes with a 1.6L makes it much harder
