asap according to me, according to piggy, a little bit slower than that ;)

i run a lj torana radiator cut down to suit the 1200 apron, never EVER, over heats the a12 turbo. just an idea.

if you can find a good core, the C20 vanette comes with a 2 core wide radiator with the outlets in the right place for the A series,cause it has an A12, & the C120 with the A15 comes with a 3 core radiator in the same width. It's just hard to find a good one as their pretty exposed to anything coming up from the road.
