For the 2006 model year vehicles Honda switched to the Rev 8/04 SAE standards for measuring hp. The base RSX for 2006 was rated at 155 hp (116 kW) and the Type-S was rated at 201 hp (150 kW). In 2005 the RSX Type-S received camshafts, b-pipe and muffler, 4.77 final drive ratio, crankshaft pulley and the intake snorkel duct from the Japanese model Honda Integra Type-R. The rev-limit was also increased from 8100 rpm to 8300 rpm. Another major change made to the inline VTEC-i engine was the use of a timing chain rather than a timing belt, which reduced maintenance needs.
