Folks,
I picked up a set of IDA's in good condition that were set up for a 2.8 (maybe an RSR?) -- anyway, the IDA"s on my /6 have throttle shaft issues, so I figured I'd just swap some parts back 'n forth to get the correct setup for my stock 2.0L /6. Turns out my original IDA's weren't exactly stock either. There are several parameters here. Idle jets are currently at 55 on both carbs. (stock is 45) I'll be using 55 initially. Mains are 125 on my current set, 155 on the new ones, stock is 105. I'll be using the 125's. Emulsion tube on mine are F26's (same as 911L), and on the new ones they are F3's (911S). The originals used F1's. I've no clue which one I'll use -- if I'm lazy, I'll leave the F3's in there. Air correctors are 180 on both IDA's. Original's used 170s. I'll use 180s. Pump Jet is 50 everywhere. In the picture you will see two different auxillary venturis -- the shorts ones are stock /6, and the tall ones I've not seen before. No clue what to use. Lastly, and I've not got this far as I have to cut wires, but from an eyeball estimate, the actual venturis on the originals were quite a bit more restricted. I'll pop both of them out shortly to see what they are --- i'll use whatever is closest to the manual I guess. Comments welcomed. kim.

QUOTE(Gint @ Feb 8 2004, 08:53 AM) ...I may even move this thread to the "Classics" section. As usual, Kim asks questions and receives responses that I (and almost certainly others) can use as future reference. yup - i am more than a little tempted to go pull the carbs from my car just so the information can be added here. at one time there was a standard "upgrade kit" of jets, venturiis, and emulsion tubes that was spot-on for the 2,0 /6 - and produced noticeable difference in my E-cammed but otherwise stock engine. i did add the tall '906' secondary preatomisers - mine were pretty rough with casting flash on the support struts but a couple of hours with needle files cleaned them up nicely. (at full chat, air moves through there at just about Mach 0,5...) i have to go pull a strut and the front antiroll bar from the car, so another few minutes pulling the induction would not be a huge hardship ... |
