Sorry bout that, there are so many folks on this board that I forget to update (or backdate) my stories.
Here is the deal in a nutshell:
Turbo swap into a '78SC
- Motor is '78 930 w/CIS
- SC cams
- K27-7200 turbo
- 1.0 bar spring
- Euro exhaust w/no smog equipment
- Stock type muffler
- Large B&B Intercooler
Everything has been rebuilt and needs adjustment. This is my first turbo motor so I'm not familiar with the quirks or tricks.
I understand the relationship between timing, fuel mixture, and idle adjustments but don't know what to expect from the tuning inputs. Timing would be my guess as to a starting place, then fuel mixture, then idle.
Little things cause big problems, such as - do you tune with the air cleaner on? An if so how do you reach the set screws? I physically cannot reach them due to the stock airbox and my big hands.
There also may be some problems with the CIS. This will also muddy the waters. I'm hoping that the tuning can be done in spite of possible CIS problems that will bear themselves out afterwards.
I'd just like some input from folks who have tuned these engines and can tell me how they should behave given the different tuning inputs. I have a friend with a 930 who is very helpful but is short on time right now.
Thanks
