Hi everybody,

I recently worked on my exhaust (1983 Murena 2.2) as one of silencer's mount rubbers disintegrated. I was not readily able to source a replacement rubber, so I asked somebody to make a few out of EPDM and polyurethane. If anybody’s struggling with the rubber, I can explain what I did. Let me know. Happy driving!

Yep, that's what I did as well. The original is 0.5 so I simply used the old cap which indeed is a good fit.

I do believe I seen an 80kpa short reach cap on a tractor supply site somewhere during my search... 🤔 I wonder why I didn't link or haven't mentioned it previously. Maybe I misremember it.

So Spax combined with rear springs from the 2.2 but fitted to the 1.6? I imagine that makes it quite a bit stiffer. Does that make it feel more responsive in corners?

That looks good 👌

the clutch hydrolics on the 2. 2 I had several times problems.
A good solution is a wilwood cilinder that have 22 mm cilinder and a slave from a peugeot (504)

It ha M10 x 1 so its possible to mount a cupper pipe between them using breakhose from a peugeot 205 front at the rear to let it compensate te movement of the engine.
Th wilwwod kit has order number  260-3376 7/8" Bore Master Cylinder Kit.
It is 22mm. I know it is a little bigger then original but its proven to work good.

At first I mounted Spax on the 2.2.
It made things as height strenght adjustable.

Later I mounted them on the1.6 and also new springs from a 2.2.
At the front I mounted Koni shocks
That was realy progress concerning road handling.
I am very pleased with them.

Sounds great Roy!

What I want/need to do is first get the Murena driveable, get the gas installation removed  from the carregistration and then the APK (MOT in England). Then the car is road legal. This is almost done!

In the main time I will revise the second cilinderhead and fit it with the Holbay cam. Make a good exhaust and get the 2nd flywheel machined. When all that's done exchange the original with the revised one, and off course fit the new flowed exhaust and lightened flywheel. This will take a couple of months. Enough to get used to the Murena and notice a difference in performance.

Thank you very much!

Hello Henk,

No, the ignition doesn't need to be changed, it is fine just as it was originally.  You don't even need to adjust the timing.

I have run a Murena 2.2 for many years and many thousands of kilometres with a standard Solex 34 CICF carb. a standard camshaft reprofiled by Holbay to their 58C profile, commonly named the Tornado cam, a four-into-one gas flowed exhaust manifold and stainless steel silencer with one tail pipe on the left like the original. It has the original Bosch distributor, standard electronic specification 12v coil, standard amplifier, and standard 10 degree BTDC static timing, using NGK BP6ES plugs and it runs fine. It also has a lightened flywheel. It produces around 140 genuine bhp. The Murena 2.2S was rated at 100 kW on the Certificat de Conformité and that, when it is correctly converted to bhp, is only 134 bhp. The claims of 142 bhp are erroneous as the incorrect conversion factor was used in all the Matra advertising. This has all been detailed on my website for years.

I have owned a genuine 'Prep 142' and driven a genuine 'S' and I know mine is slightly quicker as well as being better on fuel economy since the 34 CICF down-draught carb. is more economical than two twin side-draught carbs. in normal fast driving, and I get between 10 litres per 100km (worst) and 7.1 litres per 100km (best) (that is between 28 mpg and 40 mpg!) and I mostly drive fast but I do have the high 5th gear fitted which I pioneered! I would normally easily achieve 8 litres per 100km or say 34-35 mpg on a run. Even before I fitted the high 5th gear I would easily get 8.7 litres per 100km (33 mpg).

Hello,

I'm Henk Scholte from the Netherlands. I am restoring my Matra Murena 2.2 from 1983 which is almost done. I had a donor car so lots of extra parts and therefore a spare engine.
This one will be repaired. The camshaft looks quite good, and I want it machined to the Holbay specs. I allready found a machine shop for this. As I understand the Holbay will work fine with the standard Solex carb.

What i'm unsure about is the ignition. Will this have to be changed also, or is adjusting the timing enough?

Thanks.

Henk

Ah then I guess I seen another one on marktplaats
