KR with 2L bottom end? Advice please
I've currently got a 1.8 16v KR in my mk1 cabby sportline. It's pretty standard other than a stainless steel 4 to 1 manifold. When the car is off the road during winter I would like to make it about faster so though about a 2L bottom end. Any other low cost options for more power?
So my question is;
What is needed to fit a 2L bottom end on a KR?
So far I believe I could use a 9A or ABF but the 9A is easier?
Thanks for any help
James.

I would go complete ABF with management and ditch the k-jet.
Your Sportline should be ce-2 so it would be pretty easy, plug and play!

9A (or 6A from an audi, this would need oil pickup and sump changing) are the same block as the KR, just with a larger bore/stroke.
The ABF is a taller block (16mm) but uses the same bore/stroke as the 9A, it just has longer rods to create a better torque curve.

you can run abf or 9a/6a/ace with the stock managment, however abf is taller so your manifold may hit the tunnel so bear that in mind.
also unless the kr has a ported head there is no need to swap it over to the 2.0 bottom end if you get a complete engine, just fit the engine complete.
however if its a 6a/9a/ace you will want to swap the kr cams over if you havent already done so, as the original cam will be lame. the abf has best cams in already so keep those if you go that route.
if you want full abf managment route then you'll need the loom and the ecu along with the block, plus all the inelt manifold, throttle body etc. thats all you will need though the old fuel system will be more than enough for the abf stuff.
