Does the High Camshaft and ECU Kit fit a CVT CR-Z?

No. Spoon states plainly that the high camshaft and ECU kit is for manual cars only and is not compatible with automatic transmissions, which on the CR-Z means the CVT. It is registered for the early ZF1-100 series manual car, so a CVT owner should not order it.

What does the factory system do at low revs?

To save fuel, the CR-Z uses VTEC to hold one of the two intake valves in each cylinder nearly closed at low engine speed, relying on the electric motor for extra pull. The High Camshaft and ECU Kit keeps both valves opening, so the engine itself breathes fully from idle.

Will fuel economy suffer?

Spoon does not publish economy figures, but the factory system exists to save fuel, so some loss should be expected, especially in town. In exchange, the engine responds more crisply at low revs and pulls through to a 7,000 rpm limit. A driver who mainly cruises on the highway will notice the change least.

Does it fit a US CR-Z?

Spoon registers the early ZF1 manual car built up to August 2012, which corresponds to the first US model years. Go Tuning, the sole US distributor for Spoon, lists the kit for 2010 to 2016 cars, but the later updated cars fall outside the Spoon registration, so BA will confirm before shipping an order for one.

Is the work suitable for a home mechanic?

Only for an experienced one. The job means opening the valvetrain, swapping the intake camshaft and rocker parts, renewing seals and checking valve clearances, then having the engine computer reprogrammed. A Honda specialist will do it faster and can confirm the hybrid system shows no warnings after the change.

Spoon Sports High Camshaft and ECU Kit for ZF1 Honda CR-Z

The Spoon Sports High Camshaft and ECU Kit for ZF1 Honda CR-Z undoes the economy compromise in the hybrid coupe’s 1.5-litre engine. At low revs the factory VTEC system idles one of the two intake valves in each cylinder to save fuel, leaving the motor assist to cover the shortfall. Spoon’s camshaft and rocker arm, derived from the parts it developed for the Fit, keep both intake valves working all the time, which Spoon says lifts low-end power and torque. The kit comes with a matched calibration that sets the rev limit at 7,000 rpm and the VTEC changeover at 5,300 rpm. It suits an owner who bought the CR-Z for the manual gearbox and wants it to feel like a Honda sports car; anyone chasing the best fuel economy should leave the car as Honda built it.

How the Kit Works

The kit replaces the intake camshaft, rocker arm and rocker shaft, with new seals, and Spoon rewrites the CR-Z engine computer to suit the new valve timing. The hardware is based on proven Spoon Fit components, so the design has a long service record behind it.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
