I have a 1979 non turbo,and want to add a turbo.I have the intake,exhaust and turbo ,oil lines etc etc. HOWEVER !!!!! I am having problem with throtle linkage not able to fit between exhaust and back up to the linkage.
Anybody ever try to add a turbo to non turbo engine???? (I just need more power !!!!!!)

bad idea dont do it. the turbo engine is engineered different including oil jets for the clyinders. If you want a turbo in your car just drop in a complete turbo engine. You run the risk of damaging the engine and transmission with you add a turbo to a non trubo.

The non-turbo engine can't handle the stress of a turbo.

Its simpler to simply buy a good used turbo motor and do the swap.

There have been lots of threads here regarding the differences.

You'll spend more on parts than just swapping the motor will cost....and you'll be gettting the factory developed comprehensive system. I would buy a good running car complete which has cosmetic or body damage and swap all the desired parts over.

If I find a turbo engine..is the trany the same ?

It might be best to get the engine and trans from the same car if you can...
that way you know they fit...
about 1980 there was a change concerning something with the method of controlling the shifting.. vacuum related.... and you need for your engine stuff to match the trans on that...
It even varies depending on the model as to when some changes went into place... Someone who knows more will speak up soon I hope... I just know that my 79 wagon auto trans from my NA car did not match up to a 1980 car in terms of that vacuum control...

pre 80 I think there was no vacuum. Can't imagine why switching the headers would change this.

If you set the non turbo up correctly, the difference really isn't that bad-
I find most 300D nonturbos are not tuned right, and therefore, don't run right.
If you make sure your injectors are all set to 1700 PSI, the injection timing is 24degrees BTDC, the valve clearances are set, the fuel system is clean and the accelerator is travelling to its maximum position, you will be fine.
you won't even worry about the turbo being there.or not.

Just curious, If you are truly an MB tech why dont you service new MB's at your shop? seems kinda odd some whos MB trained should be able to work on the new Benz just fine and also seems kinda stupid from a business point of view when you only do old benz's limiting yourself. Prety much every indy shop in my area works on the new ones as well.

The numbers arent adding up

LOL, I find it rather odd why you wouldn't understand why a mechanic wouldn't work on new cars, epically new MBs. My indy and good buddy wont and hes been in business for over thirty years.

a difference between a indy and MB tech. An indy is understandable why but someone who has had factory training and the special tools now thats not.

Something about this guy is bs.

Could be for the same reason my brother went to law school then decided to be a school teacher, he would rather do something he thought was less hassle or just something that suited him better. My indy/buddy is a factory trained "Jag" tech and now wouldn't touch one with a ten foot pole, VWs either, just because he doesn't like em and doesn't have too.

For sure. There is a very big difference in performance on my car when I disable my turbo (Keep the vanes wide open). Normally I only needto revv to 2000rpm before shifting, without it I have to revv to 2500-3000rpm to go as quick.
