Hello 1200 fanatics,

>what mods do you need to do to put webers on a
>standard a12 engine and how much will it cost

It's been many years since I had the twin Weber 45mm carbs on my A1200 motor, but I do remember this much.... The first thing I had to do, was get a GX head from an import (from Japan) Sunny
GX engine). This head has the bigger valves and huge (for a 1200 cc motor) oval intake ports. This head is key to everythiong else, and without it, you really can't do the twin side draft carb
thing and get really big results. I next bought a Nissan Comp. dual side draft intake manifold. I also got a beefy, high lift, big overlap cam from Nissan Comp., a racing version distributor
from Nissan Comp., a set of Nissan Comp. headers, and cc'd the head and installed J series flat top pistons, resulting in an 11.5:1 compression. Of course, a free flow exhaust system was also
installed. It's been too many years (nearly 20), so I can't even talk about prices or availabilty.
The engine was pretty potent once it got to 5 grand and it pulled crazy right past the 97000 rpm redline I had it set at. As a sidebar, I still have the rare factory 10 grand tach in the dash
of White Zombie.

See Ya.........John Wayland
