Sure, a 1911cc motor will put out more than a stock 1.8 will. Especially if you bump up the compression about a point. You'll have to run "super" grade fuel (probably, not certainly!) but it'll go better. A set of real headers will also help release some of the power in the motor.

Since you're keeping the L-jet, it might be prudent to use a Wide-Band O2 meter to make sure the mixture stays reasonable under most or all operating conditions. It wouldn't be any fun to lunch the motor due to running lean.
