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 |

Likewise, for about the last four years. I'd been messing with the mixture, trying to find the happy medium between head temps and fuel consumption (too fat)
Retarding the timing, and installing the aux oil cooler has it now at the point where I feel it's finally dialed in very closely. The last issue was the idle, I've now got it in the 950 range, and the car just feels better. Drove it today, 75 degrees, and at highway speeds my oil doesn't go over 210, and head temps are right around 340. (IMG:style_emoticons/default/smile.gif) Under load, and pushed uphill, 375-380 is about where it peaks. I'll check that idle timing, and see if I'm close to that 14 number. Then I'm gonna call it good... |

Then I'm gonna call it good... I have the cam and compression numbers of the original poster in a 2056. Idle is generally smooth. My only problem has been trading fuel ratio with head temps. Needs to be awful rich to stay cool. I will try the timing suggested by Jake. If I were to do it again I would have used a stock cam. Btw, where can one obtain a stock grind on a new cam?? Of course auto correct is more interested in seafood and made it clam. |
