that was me that said go for the 2t.
actually a 2tg if you can find one.
or a 3tc if your desperate.
they are more interesting than a 4a, and the conversion is easier.
you can pickup 2t,3t,2tg engines and parts cheap if you look around.
the hardest thing is gearboxes, thats why I'm stocking up on them.
and whats better is you can make a hybrid 3tg, 1.8lt twin cam.
from the outside its a 1600cc, hehe.
