GT4 with CIS?

I noticed that too. (duh! ) I originally thought it was the white/blue one with the electronic ignition and some rust that sold and re-sold two months ago, and then I saw the injection. So this is a different car.

My first thought was, that it'd probably run smoother and be a little more reliable. But ya might miss the sound of the carbs though...

 

I think more that its isn't the original motor.I mean you have guys on the board that want to convert from cis to carbs not the other way around

 

lets see a 1975 in CA. most likely was done to pass smog, also notice the airbox that's not the mondial or 308 variant. wonder where it came from? custom?

 

It would be interesting to know if he grafted the plenum onto the existing (carb) manifolds, or put the injected manifolds/plenum on the carb block, or if the whole engine is from a Mondial or 308.

I would say that a GT4 missing its carbs has been castrated, but then again, now you can put Scott's BLOWER on it!!! <evil laugh>

At what point in CA are you simply exempt from smog testing?

overall, what's the deal out there?

 

I'm not an expert in CA emissions, but it was my understanding that 1975 was the cutoff so a 1975 would be exempt but a 1976 would not.

That would be the only advantage

 

Yes. The cutoff is 1975. That's why I bought a '75. It can also have Scott's blower put on w/o any emission issues, which is a fun idea.

I'm just wondering how much it'll all cost.

 

As I understand the law, 1975 & previous cars are exempt from smog test, but not smog equipment, removal of any standard smog equipment it still illegal, although chances of any problems with authorities is small.

 

The CIS was put on this car so that it would pass smog. It is exempt now, but not 10 years ago when the CIS was installed. It is the original engine (according to seller) with the CIS intake manifold from a Mondial and a custom made air filter box. It apparently cleaned up emissions some 80%. The only other advantage to the CIS over carbs is that the back of the car is not covered in soot, which on a white car is even more important. The shop that did the conversion apparently disposed of the original carbs and intake manifold.

 

Disposed.......yea right bet they were either rebuilt and installed on the next customers car or hit e-bay

I wish someone with a carbed engine would burn a CD for me so I could drive around my 85 and hear what what I am missing

Mine's pretty obnoxious......new ANSA on soon.....it cleans out in the upper rev's.

 

In this case I'm sure that "disposed" doesn't mean they went in the trash, it just means that you can't have them and they don't come with the car.

The car definately is quieter under full throttle with the CIS, but maybe even more than that because the air cleaner seems like maybe it is too small which may be a problem with airflow (maybe not), but maybe also lets less sound out. It also has the stock exhaust. The paperwork says that a shop replaced the thermal reactor. Did '75s have a thermal reactor or was this an effort to get the emissions down?

 

Ok, for our F-chat bretheren out of CA (u lucky biyotches!), here are the draconian rulz we live with in the Golden State.

1975 and earlier - smog exempt, except that all OEM smog equipment must be retained and functioning. That means it has to be hooked up, but no one will test it to see if it does anything. For 308GT4's this means that we poor saps have got to find the smog equipment u guys probably ditched decades ago and reinstall it. Primarily this is air pumps, plumbing, carbon recirculating cannisters and PCV's. It may extend to exhaust manifolds where there are injectors or sensors IF the smog inspector cares enough to check. For my last issue car, it was a visual inspection to make sure that the air pump was connected and the fan belt turned the pully.

Rolling exemption date - the 1975 date is supposed to roll forward 25, then 30 years from current (arbitrary change under review - allegedly). We should be on model year 1981 (or 1976 under the 30-year rule). Car clubs are trying to get the rolling exemption moving again.

For 1976 and later, car has to have the OEM equipment installed and functioning and pass emissions test for the period. Try that without your thermal reactors or cats! If u fail repeatedly, meaning that there is no reasonable adjustment or modification u can make to pass and u have failed several atempts, then u can appeal to a smog referee. The referee will review your case and, in the case or Ferraris, deny u because u can afford to make the car pass (my cynical opinion). Then u will retrofit cats onto your exhaust and pass somehow.

Alternative 1: you can register your car in a CA Clean Air County and bypass all the smog crap since they do not test or participate in the state's smog program. There is 1 county I know - Plumas County up north, but there are more. Of course, u need a residence up there...

Alternative 2: you can register the car out of state and keep it in CA, however, u will be questioned about how much time the car spends in the state. Most of the time u fly below the radar, but technically u can only keep the car here 10 days or u have to have a temporary registration (in the case of a visitor that is staying longer) - not sure how this works, tho.

Alternative 3: have a car collection/dealership (u allegedly have cars for sale) and use dealer plates on your problem cars. Technically u only are supposed to use them on a limited basis.

So there it is. On that CIS car, the CA DMV might want the car to smog qualify based on the production date of the engine, assuming an inspector identified that the engine was a transplant. If the induction system is the only transplant, then it's up for grabs. The thermals are from 1976 and up until cats were substituted as a safer means. Thermals are lined with heat sensitive iron particles that heat up to burn excess hydrocarbons in the exhaust, but the heat load on the surrounding area is incredible. Imagine putting that on a fiberglass 308!

 

Man...if I had the dough...would love to see what this car could do with Scott's blower set up. What do you think she'd do with 300 plus ponies at the pavement? Sub 5 sec. 0 - 60? 160-170 mph? I'd love to find out. If I could just find the cash...

 

You would have to change gear ratios as top speed on a gt4 is limited by the redline not power. I'm not sure I would want to go that fast in a gt4... though sub 5 sec. 0-60 sounds pretty cool!
