74'+ oil tank into a 71'?
Guys,
I have a 71' with original tank and have been resistant to changing it despite having a 2.7 ltr Webered engine with large front mount cooler set-up etc... I have the 26mm to 30mm adapter and jerry rigged 'S' hose too. Now I was putting in my 'S' gauges and went to install my new oil level sender and guess what, no hole to install it into. I could drill a hole and such but I think the time has come to get another tank. So my question is, will any 74'+ tank just drop in? Is the filler/oil filter and such in the same place or am I looking at fabrication work. I assume my 'S' hose will just slip on and the 26mm/30mm adapter will be ditched? Also is this a good opportunity to put in the RSR adjustable pressure regulator set-up? Thanks!!

No, the opening in the inner fender well is different.

I did it. Cut out the inner fender well to fit. It solved an oil starvation issue at the track in the corners.

It's a worthwhile upgrade. You will have to do some sheet metal work in the engine compartment though.
A newer style front cooler will bolt right up as will the "s" hose.

What material are the tanks? Brass? I suppose I could just modify the return fitting from 26mm to 30mm and cut the hole for the sending unit. Thats the only real difference right? I mean there is no other secrets to the 74+ tanks right?

So it should not be too difficult rob a 30mm male fitting off an old pipe or tank and TIG it on there?
If I have to start cutting stuff I would rather it not be my car but a removable part like the tank. Cutting a hole to mount the sender is not a biggie. Thoughts? Quote:

The advantages to the newer tank are:
More capacity. The return fitting has been relocated so you won't starve the motor of oil during braking and cornering. The internal passages are larger for more flow to better suit the newer motors. You then use the newer oil filter which has more capacity. When Porsche went to the 2.4 and larger motors there was a reason why they increased the oil capacity of the tank and oil lines.

Here's a pic. You can see where the old hole was since I didn't bother to spend a lot of time to pretty it up where I welded in the patch.

What about going the other way? RS/RSR/ST R?
What did they do?
