Yup. If an Rb26DETT can fit...inline 6...I don't see why a L28 wouldn't fit. My question is Why swap with an older motor? Seems back asswards. I see quite a few people with 510's and 240, 260, and 280Z's swapping newer SR's and RB's but no so much old motors into "newer" cars (s14). But hey, to each their own.
