Your right, a rotary engine is poor for torque and speaking for the 13B very smooth running, I liked them for a while. (so did the petrol stations, exhaust shops, brake shop etc.)

Geeze they get a bit tall after you put on the fan etc. so much for the low profile!

Have you tried a NZ site as per grumpy's suggestion? know any Kiwi's?
I have a good Kiwi site etc. somewhere, I'll have a look over the nxt week or so, and

seeing a Kiwi expat over the break (who goes back on occasion), I'll ask...
Merry Christmas Mr. Blumbly
