do you plan on road use as webers is difficult to engineer with pollution motors
are you already set on the motor?

its funny how corolla peeps often move up to the Nissan ca18de
Plenty of suzukis sierras also use the ca16de and ca18de
while some sunny guys want to use the 4age :}
corollas with both engines relatively stock to mild often
end up with the ca18 as the winner due to torque.
