2871? would that be a t2871? not sure but it sounds like it could be a t2 also, in that case, check autoparts store, search online for wat cars came stock with a t2 or t3 turbo, i got mine for my t25 from an 88 nissan pulsar with the 1.8 sohc turbo motor in it, i think the older 300zx’s came with t3’s tho so check that
