Need a heater try this:

could someone comment on the statement that "any engine with more displacement than 2.4L needs an external oil cooler"? this is, of course, in reference to 911 engines. don't know if the 3.0L/3.2L conversions have external coolers. but maybe this idea suggests a 2.4 is an easier installation although there is no substitute for cubic inches (or rather, cubic centimeters!)

Why not just use a Boxter engine. I've seen 2 or 3 advertised in the $5000-5500 range. The swap would seem to be a fitting tribute. Knowlegeable sources say it'll fit, although the plumbing is tricky.

I strongly recommend using an external cooler on the 3.0 and 3.2 liter motors. You can use the metal tubing out of the motor and modify it (cut it in half) by having a AN 12 or AN 16 fitting welded onto the end. Then run your lines.

ABSOLUTELY! For any engine (in a 914) over (I'd recommend) 2.2, you need an external oil cooler. The facts are that you'll be running this thing quite a bit harder than you ever did your -4, and that heat's gotta go somewhere. Best bang for the buck. BTW, I still have those pristine 914 seats. . .

Any motor larger than a 2.2 will need an extra oil cooler. Most cut the existing 6 cylinder lines , as previously suggested, and add the cooler in the front trunk , ala 914-6 GT. The shrouding is available to cover the cooler in the trunk. You will have to open up the nose below the bumper (take a look, there are assembly line plastic plugs there already, cut a few more holes to admit more air) and then decide whether you will cut an exit in the trunk floor or use the assmebly line 3" holes there. For spirited use, a rectangular opening equal to 2/3 the size of the cooler will suffice. You can use -12 an aircraft hose to route the oil form the rear to front. Though the original 914-6 GTs used the driver side rocker to route lines, it is better to use the passenger side- more room. I recommend a thermostat as well. Mo Cal or Troutman sells good units. Good luck with your project

To the matter of an external oil cooler.
I ran a 2.4 T (140 hp?)motor in my 914 with out the extra cooler, with the following caveats.

There are a number of tricks to keep it cool, particularly in a 914.

Cutting the air deflectors as described in B. Andersons book.

Blocking off both sides of the engine shrouds
at the front of the motor. This also helps access to the distributor on the pass side.

Make sure those little flaps mounted to the
bottom of the car at the front of the engine room are in place and in good condition.

Remove the rear valence.

With the above completed, I had trouble getting the thing up to temp !! Took about 15 mins of driving to make it to 80C. Never saw 100C even in the hottest weather.

The cooling requirements are more dependent on HP than engine size. Anderson recommends
an external cooler on any engine (911) with more than 160 HP, but also notes that 911 motors run hotter in 914 installations.

The 2.4L has been replaced with a 2.7L and the cooler went in the nose...no getting around that(210-220 hp, hopefully).

BTW, Troutman or OEM Porsche thermostats are the only ones I would use.
