so could you throw the a10 flat top pistons into an a12?

A10 Pistons are flatop as far as I know.

turbo injection and electronic ignition...boom thats 100 horses right there... or 100 shot of nos. lol

ive heard a fair bit bout flat top pistons.
how much are they worth and are they easy to come across

There are several things you can do: First off you can rejet the standard carb. (Weber 32/36 would be better of course) As mentioned you can go to a bigger exhaust. The flat top pistons will help regardless of any other mods. On the oval port head if you have the carb that came with it use that. You can also gasket match the manifold/head. Electronic ignition from a 120Y.Go to a 14lb flywheel. Keep it in proper tune etc. I would guess you that you could get the A12 up to the 75-78HP range. You might be able to ditch some weight out of the car as well.

I know he was offering it here for $350 or
something, that is mad! I should sell my a12t
getup once it's all shiney!

and his a15 motor

Did you see how much Chris's went for?
Faaark me

just get a gx setup

You suffering form P plater? The thing is that the standard carbies are really only an economy carbie, you can't get more out of them unless you have all the gear the Japs are using in their historic class racing.

But for fun that doesn't look illegal I'd go a weber 32\36 carby conversion, I mean weber make all this stuff for "problemmatic" carbies. I reakon that standard carby is "cough" "problematic"

Add a slightly larger exhaust all the way through and it'll be fun
