What are my options regarding performance on a BP hybrid ('96)?
Turbo is not allowed, so as decat.

I already have a CAI, and maintain my engine religiously.

adjustable camsprockets, piggyback and let your cams timing retard between 6 and 8 degrees and go to a 140 hp at the cranck.

Otherwise you best look in my topic, complete n/a overhaul/tune up

How will it affect fuel consumption?

Ofcourse you'll lose some fuel economy. bottom line is: you want to go faster, you have to spend more

might as well convert it to a manual
