to lsd or not to lsd

is it worth purchasing a Limited slip differential for my roadster, i don't have a donor vehicle but i am using a bmw 1.9 engine from i z4

I think the lowest powered engine from the BMW Z4 is the 2.0 and thats around 150bhp. So its well within the practical / fun range, without being a handful. Its on par with a C20XE Redtop, or a mildly tuned Zetec. You'll be fine without a LSD. Infact I'd go so far as saying it would be more fun and a little more predictable.

meant to type z3

Oh, well thats even less power then. Unless your going to be racing it in competition, I doubt your ever going to need it. I'd say its not required unless your clearing 200 ft.lbf

there is an american company that supplies supper chargers for this engine but the whole kit is about 4 grand

I think I read some where that the car is to light to make use of the LSD so it's not really worth having one?

most ford sierra lsd's are shagged anyway. finding a good one is like finding a petrol station that gives the stuff away for free.
