Anything is only worth what someone is willing to pay imo. If you needed a known to be working well lsd box in a hurry and 500 was the price for that piece of mind, personally I'd probably pay that over a 3/400 box I didn't know so well.
Seems a little steep but with the price of an ek9 increasing slightly in the last couple years it wouldn't seem unreasonable to see the standard parts increase in value also.... Anyone wanna buy my b16b lol?
Hmm, I've been offered a fidanza flywheel, 4.4 FD parts and LSD for £450. Doesn't sound bad then? As I know my box is good, may be safer to convert mine
