How about the GA16DE out of the N14/15 Pulsar. The one I have in my Pulsar is very quick, someone mentioned they come close to fitting the standard A series bell housing, but have the problem of the dizzy coming out the back of the engine. Using the MA09/10 or the SR16DE would have the same problem with the distributor, I believe, as they are front wheel drive engines also. Given the history of motorsport in Adelaide, I'd guess there was somebody who could help you over there, Adelaide was home to Elfin, K&A, Globe, CSA, etc. A one off cast bellhousing to suit a T3 corolla box, with a H165 diff behind it all would be how I'd go about it. Dellow Automotive has a bellhousing to suit the A series, maybe one of these can be modified to suit. Would be quite a lot of fun in a 1000 ute. Also ask DVR1000 about his front brake conversions if you do the 1000.
