240D Non Pneumatic IP?

Hey guys..

I've got a '75 240D and am looking for an IP that doesn't use the pneumatic governor.

What year did it change over and will it be a "bolt on" swap?

I've searched a bit but couldn't find what I was looking for.

Thanks
-Chris

It won't be bolt on. The pneumatic IP used it's own sump and oil supply while the newer style one is tied into the engines oil supply.

Is your car sidelined due to your IP not being fixable ?
What is the brand and serial number on your current IP ?

Nope.. its running fine actually but I'm wanting to get rid of the vac. signal style governor

As far as the oil goes... wouldn't that be a simple matter of teeing the oil pressure port and running a feed to the pump as well as a drain back to the pan?

I know its been done as I've seen some boosted 240s... cant run the vac. style pump with boost...

Thanks for any info.

BTW... yes I know its not wise to do it.. yes I know the engine isnt designed for boost... etc..etc.. But I'm a fabricator and don't mind the work.. just want something different. I really like the 240.. just want a little bit more out of the motor.. I figure 8psi or so with fueling to match should do the trick and not stress components too much.

We don't care if you blow up your engine... only that others reading the post are made aware of the potential for harm to the engine.....
Have you considered putting in the Turbo pistons and oil squirters ?

If engine failure does happen... I will consider it then.

I currently have approximately $300 in the car.. engine runs good and I don't want to tear it apart without need.

I do plan to keep EGTs in check and tune it properly... if EGTs are at or below what they run in NA form, and injection timing isnt changed, The piston's temperature as well as the valve's temperature shouldnt be effected.

The engine's lifespan will be effected most by tuning and properly sizing the turbocharger.

Yes there is risk and I didn't mean to sound off or what have you.. sorry if I did.

There are many differences between the NA and FI engines from the factory... oil pump, pistons, piston coolers, oil cooler, intake design, IP design, etc..etc.. and yes any increase in power output has the potential to cause damage or decrease life expectancy.

With all that being said... what pump would I need? I know that its been done but I can't find the "how" its been done and with what parts.

Thanks again
-Chris

I didn't mean to sound smart with my "wouldnt it be as simple as..." comment..

I honestly don't know so I was curious if it was that simple or if oil was supplied through the main shaft in the pump, etc.. etc..

Just wasn't sure if it was an easy fix...

I was not being smart...... I really do not care what you do with your engine.. it is your engine... and I have taken apart stuff all my life which never got put back together.. just to see what it looked like..... not much difference in taking apart something and it never being used again and blowing it up.... except it might be more exciting with the latter...
We have had some people who seemed to be trying to get others to do the same experiments with their engines... the only part I objected to was they seldom admitted the potential problems or costs.... you can get some new to machines excited about something without describing the overview... and not fair to them not to warn them.. that is my only place in this...
So , go for it... and don't worry about people in the peanut gallery....

I suppose we could list the differences in design which make the turbo a long lasting engine..

1. special annular ring pistons which work with the oil squirters along the inside of the block to keep the pistons from melting.
2 larger crank and rod bearings.
3. ?

Gotcha... just wanted to make sure I wasnt coming off the wrong way. I certainly don't want to lead anyone down the wrong path.

So... would it be possible to just change the rear portion of the pump that has the governor and ALA?

After some digging, I'm reading that the "kits" that were offererd back in the day retained the Pneumatic governor... The question is how...

The Throttle linkages are going to be different and if it has an Auto Trans what actuates the transmission will be different.

The other thing is... I think.... that if you turbo something... the ' rate of fuel injected' ... I think by a cam inside the injector... will be different from an NA curve... and without extra fuel per revolution you will not get extra power.. and might even get a lean burn...
