haha quad foddle body, are they taking the piss?
could be worth getting, but how much time, money and experience do you have?
basically, you will have to completely rebuild it. Thats going to take time.
I think that a time period of less than 2 months to get an engine, rebuild it and have it running and in your car is a little bit unrealistic. Have a look at some of the engine conversion threads on this site and look at the time frame, and this is more often than not people who know what they are doing. From what you've written it seems that you are new to this type of work.
Buy it if you want, in the long run it will probably be cheaper, but remember its a 20 valve and from what i know it requires more modifications than a 16 valve to put in.
have a look here http://www.rollaclub.com/board/index.php?showtopic=29506 provided by LittleRedSpirit, he's done the conversion.
The auction is only for the engine, so you're going to need the cooling parts, crossmember from an ae86 or a ae71, gearbox, diff, extractors or exhaust manifold, inlet manifold (both these required for a rwd conversion, 20v only came out in fwd cars) distributor relocation parts (i think), an ecu and the list goes on.
but go for gold if you reckon you got it in ya
GOOD LUCK!! :lol:
