Honda has released a new engine (or engine code at least) for the 2005 Acura RSX Type-S. The new engine is called the K20z1. It is almost the same as the K20a from the Japanese Integra Type-R minus the dual valve springs and higher compression pistons. It shares the same camshafts and intake manifold. The pistons remain the same as the K20a2. The engine produces 210hp @ 7800rpm and 143lbs torque @ 7000rpm.
When the new engine hits vtec, it is a lot more noticable than that of the K20a2. It DOES pull harder! :shock:
Also Honda has taken the gear ratio from the Japanese Type-R and blessed us with it. However we are still missing the LSD.
