i've been searching for a good priced ZC now for a little while, and Nippon has basically always had the best prices, but i was wondering, has anyone driven a ZC with LSD? honestly, i didnt even know you could get LSD on a zc motor, is paying all that extra really worth having the limited slip?
and also, would i be better off just using my Si transmission or the ZC's, i was going to put the final drive in the Si tranny, but thats too much work and i decided against that, what do you suggest?

this is the pricing nippon has
88-91 Honda Performance Engine ZC(DOHC) 4 Cyl $495 Engine+5speed Trans: $600, +ECU: $750; +LSD: $950
