- What are the F20C specifications?
- Honda's Japanese specification lists a water-cooled, longitudinally mounted inline-four of 1,997 cm³, 87.0 × 84.0 mm, 11.7:1 compression, naturally aspirated DOHC VTEC. Output is 250 PS at 8,300 rpm and 22.2 kgf·m at 7,500 rpm (218 N·m). Honda states these are net figures, not gross.
- Which Japanese S2000 years and trims have the F20C?
- Honda announced sales from 15 April 1999, although its 2001 archive page dates the announcement to May. The type V went on sale on 14 July 2000 and Gioire on 4 October 2002. The standard and type V retain F20C through the October 2003 to October 2005 catalogue period. Japan's 2.2-litre model went on sale on 25 November 2005.
- Is every facelift S2000 an AP2 with a 2.2-litre engine?
- No. Japan's October 2003 to October 2005 catalogue period is still ABA-AP1 with the F20C, and the 2.2-litre Japanese model went on sale on 25 November 2005. The US 2004 model uses the F22C1 instead. Honda's 2009 European Ultimate Edition retains the 2.0-litre engine.
- How do the JDM, US and European engines differ?
- Japan lists 250 PS net and 11.7:1 compression. The US 2003 specification lists 240 SAE net hp, 153 lb-ft and 11.0:1, with a rev limit of 8,800 rpm and fuel cutoff of 9,000 rpm. Europe's launch specification lists 240 PS, 208 N·m and 11:1. These are separate ratings and are not one unit.
- Does the F20C have i-VTEC, individual throttle bodies or a turbo?
- Honda's engineers call it DOHC VTEC, and the factory engine is naturally aspirated with no turbocharger or supercharger. Honda describes a compact manifold with independent straight runners. That describes runner geometry only, and says nothing about throttle layout.
- What oil does the F20C use?
- Honda's 2003 US owner's manual prefers 10W-30 and permits 5W-40 below −20°C. It permits synthetic oil that meets the specification, and scheduled oil and filter intervals still apply. The normal interval is 7,500 miles (12,000 km) or one year. Severe use is 3,750 miles (6,000 km) or six months. This is a US schedule, not a Japanese one.
- What are the Japanese F20C oil refill quantities?
- Honda's Japanese F20C S2000 manual 30S2A630 specifies 4.5 litres for an oil change and 4.8 litres when replacing the filter too. These are service refill quantities. Its period recommendations include Honda 5W-40 and 10W-30 oils, with aftermarket viscosity selected for ambient temperature. The manual does not establish one maintenance interval for every market.
- Can the F20C's FRM cylinders be honed?
- Honda's 2000–2003 US/Canada service manual includes a specific FRM cylinder-honing procedure with bore measurements and prescribed equipment and abrasives. FRM does not automatically mean the block needs conventional sleeves. A rebuild assessment must follow the applicable factory measurements and procedure.
- Does importing a loose engine use the vehicle age exemption?
- A complete car's age provision does not establish eligibility for a loose engine. EPA Form 3520-1 has separate engine declarations. Its code W requires use in a vehicle covered by an EPA certificate, either currently or before introduction into commerce. Confirm the applicable declaration and intended vehicle configuration before buying or shipping an engine.
- What age rules apply to importing a complete car?
- For complete cars, NHTSA's US age provision is 25 years from the individual car's manufacture date. EPA separately uses 21 calendar years and requires the original configuration or a qualifying replacement engine. Canada's age exception uses 15 years by manufacture month and year. Customs requirements and state or provincial registration rules remain separate.
- Does an engine swap automatically prevent import or registration?
- EPA Form 3520-1 code E permits a same-model replacement or an engine with any aftertreatment from a certified vehicle no older than the imported car. EPA's separate guidance interprets equivalence as the original model and configuration and advises contacting EPA before import. California engine changes require a BAR Referee inspection and label; qualifying replacements differ. An engine-code stamp alone does not establish compliance.
