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 |

To get the recommended 14 degrees BTDC at idle is there a recommended distributor or modification?
The best I can do is 6 degrees BTDC at idle with a maximum advance of 30 degrees at 3500+ rpm. |

The best I can do is 6 degrees BTDC at idle with a maximum advance of 30 degrees at 3500+ rpm. Then your dizzy has too much built in advance. This must be limited to around 16 degrees, so you can achieve 12-14* at idle, and 28-30* degrees at full advance. This makes a world of difference in idle quality, as well as all around performance, and fuel economy, not to mention CHT and OT control. |
