Hi there,
I'm about to order parts for my engine rebuild. The plan is to upgrade a 2.0 GA D-Jet engine as following: 2056cc Stroke 71mm (stock) CR 9:1 Raby 9590 cam SSI Heatexchangers Original Muffler The only thing stoping me right now is that I need verify CO2 emissions every 2 years here in Germany. My questions are now: 1. Does this set up idle well and stable at 900-950RPM 2. Does it reach the 3% CO2 spec. in idle I know that a none stock cam should not idle so low, this will be just for the time of the measurement. Without reaching this spec values I not able to register the car here in Germany :-( Thanks and best Regards, Frank |

The type IV Store does not offer the 9550.
Am I missing something? |

The type IV Store does not offer the 9550. Am I missing something? The 9550 isn't offered anymore. I have one in my car. Not a "power cam" but I am getting 39mpg out of the 1.7. I'd like to see how the 1.7 would perform with the 9590 but I don't think it would get the MPG's. |

The exhaust profile slightly changed to be more compliant with ethanol and oxygenated fuels. |

The exhaust profile slightly changed to be more compliant with ethanol and oxygenated fuels. I've been doing a lot of tuning lately and it seems like the cam likes a lot of timing on rpm ramp up. My idle timing is 14*, by 2200 rpm I'm already at 24*, 28-29* at 3500. No ping lots of power and 15:1 Afr on light throttle( around town driving). Freeway I can cruise around 70 with good MAP and about 14.5:1 AFR. |
