Engine builders quickly found ways to make more power so you still needed built engines, they ran race gas and they ended being more than $5000.00.
Maybe, maybe not…there is not much that can be done to the KZ by a tuner because of the homologation specs. Your best bet is buying the factory upgrade. The $5000.00 price tag is about right but you will pay $5000.00 for a competitive spec Honda too.
I am talking U.S. racing not international.
