nice job!

ps. your taillights are wrong way round ;)

Ha ha thats the 7th or 8th time i've heard that, and each time i swap them, i'm told they should be the other way.... seeing as everyone seems to have a different opinion on whats wrong or right they can stay where they are for now :)

Only one person picked the side skirts are back to front... dogleg should be on the rear, but didn't fit on the rear, but did perfectly on the front, so its on the front for now :)

I had some 13b housings with chipped chrome on the edges shaved down to 12a specs, and had the water seal grooves cut in.  Very impressed with the way the came out. Just needed lapping to be finished and the are going to be used in my 12a Bridgeport rebuild.






So begun pulling the troublesome old 12a apart.  Not done this with a rotary before and was surprisingly straight forward.  Soon identified that previous engine builder had bodged this together with poor porting and buggered housings!  Glad my nice 13B/12A hybrid housing will do the job! Just need my new Mazda OEM seal kit to arrive now!

Good job, nice to see her coming together :)
Power is nothing without control. Weight is enemy of performance, handling and braking.

So my seal kit arrived :)

Plus i got some 12a spares from a mate with a very rare mazda bongo van which is now being restored into a cool retro cruiser!








After being pulled down by me, engine was half bridgeported, half street ported and put back to together by Andrew at Ace Rotary who did a great job of painting it too.

So the bongo has changed hands since those pics. It was owned by a mate with an R100, an 808 coupe, a series 4 rx2 coupe and beautful fully restored 1300 wagon. Due to a house purchase, the rx2, 1300 and bongo were sold. Bongo is now in the hands of the guy built my motor so its body off for chasis check and comnence floor welding!
