Anybody with 850cc Primaries?
Is there anybody using 850cc secondaries as primaries?
I have done this mod yesterday but it seemed to me that the 850cc are a little bit shorter from the 550cc. As a result the new injectors fit a little bit short in the injector housing? Was this a problem to anyone?
For those with PFC except from changing the injector settings did you have to change your fuel maps as well?

there is plenty of info already on this mod on the forum if you do a search.
I machined a few thou off the top of my primary rail so the 850's would seal properly at the bottom. Apparently adding an extra o-ring at the bottom works aswell.
The car _should_ run ok just by changing the injector settings, but you might have a few idle issues which will need tuning out.
