Variator on 124

[wmausbach]

On one of the posts some time ago, there was a start of a discussion about variable valve timing on the 124 engine. In part of my surfing I ran across discussions about the Variator on later engines. It was first used on the old Alfa TC in the 80's. I was wondering how difficult it would be to fit this to a 124. In looking at it there are two issues.
1) The Variator is attached to the cam shaft and has to have a larger bearing at the nose. This will require some creative modifications to the cam tower. (Machining and welding)
2) The device is accuated by a solenoid thru the ECU. One solution would to use a MegaJolt system which to fire the solenoid.

Both of these are not easy but doable. What this would do is vary overlap up to about 4000 rpm and then retard the cam for high speed. This enhances the torgue in the mid range which is ideal for a street engine. By using standard parts it could be reproduced .

Does anybody have any experience with the more modern Alfa and Fiat engines using this device? Here is an article on the Alfa.

the Alfa uses a timing chain that is oiled. To try and use a system like that on the tc engine with a belt would have a system that isn't lubricated. The Alfa system also was only installed on the exhaust cam

Mark,
You did not read the article....which was on a belt driven Alfa (See pictures and diagram). It is also used on several Fiat engines that are all belt driven , not chain. It was used initally on the old twin spark engine with chain driven cam shafts.
The method of driving the cam does not have any thing to do with it.

you're right, I didn't open the link. I was referring to the old 2.0 Alfa motors
