Id love a 4 speed with 2.6,1.4,1.1,.5 the torque in a mild a15
does the rest in a humble b10. However for you chris you need a
serious cam downgrade to enjoy all that non-existant low/mid.

There is nothing like grunt on the street and I can only dream
what Lemonheads-like 83mm bores with stock a15 crank would be like
with your head and milder camshaft.

I too prefer the 4-speeder, it's much livelier. If I want a 5-speed I'd choose the dogleg as the ratio is a bit better than normal 5-speeder's IMO.

I have a 5speed for sale if anyone is interested. $600aus + $100 shipping (is in NZ). Box is in good condition (used it for over a year in my a15 Sunny, no crunches) and only needs a shifter bush as the old one was rooted and I replaced it with a plastic one.
