I had the choice between a near perfect Injected Boxer and an "OK" repainted Carbed one. Same money. Ended up with the carbed car. I wanted the last of the carburated Ferraris instead of the first of the injected ones. CIS strangles much of the life out of these cars. IMO of course.
BTW; once the carbs are set up properly, maintenance is not an issue. Carbs have been around forever. CIS may even be more susceptible to dirty fuel clogging.
CIS always had thermal time switches, cold start valves, aux. air valves, and warm up regulators. The primary diagnostic tool for a CIS system is a fuel pressure gauge. For the most part, diagnosis and adjustment was straight forward, with Lambda adding a little confusion. Power loss aside, the throttle response is pretty poor. Cheers. Tom B.
Anthony, I can tell you that on my 82 308, the cam Lift was .304 duration 217@50. All 4 Cams are the same. I think you might need to ask this question in a other thread heading. Pizzaman
The best of both worlds, I am converting my carby euro 308 to TWM individual throttle bodies. Hope to have her up and running in a month or so... Image Unavailable, Please Login
I'm pretty sure there is no such federal law saying that. Those were probably state agents enforcing Georgia motor vehicle code. Most federal vehicle requirements are for manufacturers and importers to follow; the owner/driver/consumer is typically more bound by the laws of the state in which he lives (and registers the car). You said Federal in your first post and Georgia in your second. Stave vs. Federal is a key thing to distinguish. When you hear about the Feds going after illegal cars, the cars were imported against FMVSS, not made (federally) illegal by their owners. That link you posted is most likely for construction, drinking water, etc. hazards. Don't forget that, federally, you can import almost any vehicle over 25 years old without having to make it conform to many of the FMVSS of its model year. Well, something like that.....
Regarding pros and cons of CIS vs. carbs, for many years articles and reviews have talked about greater drivability and flexibility with the injection, some noting that it helps to make up for the lost power. I don't see why that would be any different today!
while certainly true for many FI systems, the early Bosch CIS K-Jetronic has pros/cons as the technology was early and clearly geared toward meeting emission laws. While being a reliable mechanical/hydraulic wonder, it's a clearly terrible design with regard to maximizing performance. In addition to being very restrictive, due to the design there is immense inertia in the system blunting throttle response. The problem with Webers is all that stuff hanging out in the airflow and balancing peak flows with low rpm vacuum signal. For what they are they also are a quite elegant mechanical work of art that do a pretty amazing job very reliably without tweaking if time is taken in their initial set up. I'm not going to get into my usual carbs have more personality and soul than injection because many drivers really don't care about that so much anymore and ous on absolute numbers - anyway, few left have even experienced it. And perhaps rightly so, as modern cars have to meet ever more stringent emissions testing which does not tolerate a grand chorus of Webers at full song. Take what I say with a grain of salt, as I am represent just one extreme opinion.
Even me, mr. "EFI is the only proper way meter fuel into an engine" would take webers and the 10%+ hp they bring over CIS.
