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 |

I've ordered all the parts I need for the rebuild and the last open question I have is:
What is the optimum CR for 9590 if I build up the 2056 from 2.0 D-Jet for a 914. Once Jake reported very good results with a 9560 cam and a CR of 8.8 : 1 and I'm not sure if I should go for CR of 9 : 1 with my build. Any recommendations? Thanks, Frank |

Thanks, Frank In for an answer also.....I will be doing a build in a few months and 9:1 comp is what I'd like to run |
