3.0 CIS System Complete 1983 Whats it worth

[CBA]

Have 3.0 CIS system off my 1983 that is 100% and working excellent. What's it worth? BTW I've searched and it appears no one is selling a complete one or one that works perfect.

Thank you,
Joe

The fuel distributor, warmup regulator, airbox and air regulator are normally sold separately. Not much demand for the whole works.

I had a friend doing a full rebuild who bought a "complete" CIS. It ended up being a bit of a hodgepodge, and I'm not sure what he paid for it. I'll ask.

[porschyard]

Is the system a big tube euro or a small tube US lambda system, will make a difference on price and demand, i am sure Tony can give you a good idea what the value is.

I got $400 for a complete, early 78-79 big intake runner system a couple years back. it was a nightmare to package and ship.

Thanks guys, appreciate the feedback.... I've already had offers for $500 just because people needed some misc. parts. Thought is would be helpful for someone doing a build that needed the whole setup.

I have purchased so many CIS units the over the years and I’ve lost track of the total count. Here is a picture of the good AAV and got more in another box.





The price of the used parts has gone up compared to 5 years ago. As of today, I will pay between $400~$600 excluding shipping cost for a complete CIS unit.

Consistent with what others are saying, my friend reports he actually traded one set for another plus... but he'd would guess $500 depending on warm-up reg etc.

Unless your SC is a beater I would keep the OEM CIS. Will help resale down the line. Actual selling prices for full systems are pretty low unless you find the right buyer or someone looking for quality over price.

Agreed, the CIS is part and parcel of SC ownership.

Having said that, unless it has just been rebuilt and calibrated, working perfect is a big claim. Even then, we are talking near 40 yr old parts here.

Only a caveman would want to keep a relic system like that installed if another, better performing option were available (financially, expertise -wise, etc.), pNutz!

Not going full caveman !!

But yeah, that path ends somewhere for everyone. Speaking of better performing, I bet an electric drivetrain kicks your turbo azz !!

If the contest is, the car that consumes more fuel per mile when operated wins, then that's me!

gunna take the domino out today for what is likely the last ever skyline/hwy9/hwy84 & vicinity run before it goes on the trailer headed for twain harte next week. I expect to get 10-12 MPG so ill need to stop for fuel on my way up. good thing I CAN afford that...


regarding saving a CIS system for an SC reinstall or to include with a future sale is kinda hollow. if you are, god forbid going to carbs or EFI the CIS engine bay wiring harness needs to be thinned out so extensively it would be impossible to go back. unless of course you want harness connectors from the complicated 180HP 70's era injection system muddying up what otherwise is a beautifully simple, clutterless engine bay...

another CIS harness would cost more than the system itself

[Rawknees'Turbo]

Tobs, the best way to beautify a 911 engine bay is to cover the entire top of it with a pimpalicous, full bay intercooler! Yer welcome!!!

[juanbenae]

a well tuned carb's intake velocity cools the combustion air nicely.....

[Rawknees'Turbo]

BTW - our cars have very similar fuel comsimpipn numbers - around 9-12 mpg highway for me, depending on how much boosting I do (which is as much as possible - the point of owning a car like this, of course).

Thanks guys. PMAX perfect in Porsche terms...how’s that for an explaination.. Juan yes I’m going to carbs and can’t wait. It’s taking me back to my first bug that I ran dual carbs on and had a blast with. I’m smiling as I type this. Wiring harness it will be well presented in the engine bay. Looking forward to 13-14 mpg and don’t care. That electric car mentioned above is faster and getting better gas mileage but what fun is that. BTW ‘83 SC is in a ‘74 so don’t need the CIs for originality.

Love the comments keep em coming.

don't tell pnutz that you are going to carbs!!! he will lump you in with our "clan of the caveman" crew....

he and his sansei will shudder & cough like a poorly tuned CIS system...

silly, silly pnutz….

some inspiration hopefully....
