Ya they have the same engine the K20A3 and its true it's not true V-Tech. It's a form of V-Tech cause the V-Tech is only on the intake side, the exhaust side is just a regular cam. The A3 is basicaly a 12 valve engine untill the V-Tech kicks in then it's a 16 valve. I was disapointed when I found that out but with some tuning ( I used the Greddy E-manage ) it can still be a contender.
