Well Quinn you are in luck . there is a long time 1200 racer in Auckland who has got just what your talking about. It is a super rare LZ16 in another coupe of his. The plan is to run it in classics. As far as finding another LZ head, you will struggle. There are 4 that I know of in NZ and none are for sale. Reg will know where some are but the will be very, make that VERY expensive. I heard some very big figures being offered fro Japan for these parts. As far as finding another one, my advice would be to start researching the old Formula Pacific class cars. A small number of them ran LZs instead of BDAs, track down the old owners and pick their brains. The search won't be easy but you are dealing with extremely rare parts. A contact I have in Japan has an injected LZ race coupe and it sits pride of place in his living room. He considers the car too valuable to race, but wants to built a replica !!Oh by the way the largest legal capacity was 1400 for the LZ as the 1400 Excellent was it homologation platform. The FJ was a development of the LZ but most classic racing groups would not accept it as the engine is the wrong generation. MG Car Club Wellington, my club, would probably allow one at their Whittakers meeting. Your other alternative is to build a replica of a 1200 that has raced in NZ. My rotary powered coupe is now eligible to race due to it being a former OSCA car with the rotang. I don't know of any V8 powered 1200s racing but there was at least 1 Chev powered 120Y OSCA car in the South Island. I think your best bet would be to find an old Shellsport coupe and built a strong A15 for it. The 1300cc coupes circulated Manfeild in 17's which would put you in the fastest classic grids with all the grunters like the Cobras, Vipers and Mustangs... If you have any more questions PM me and I'll give you my number and we can talk some more. Wayne..
