Wooo Hooo!

I won a stock intercooler for $35 shipped! Now I'm going to have to figure out how to make it work with a '77 930.

you really haven't won anything!

Sorry I didn't mean to sound so condescending but if you are going to go through the trouble of mounting an intercooler please do yourself a favor and get a proper one.

Hell of a deal. I've seen these listed for anywhere from what you paid to $700 (people thinking they have a gold mine on their hands because of the word Porsche). But with stock intercoolers, there is a surplus floating around out there because of the many people who have upgraded to more serious cooling.

Lincoln's suggestion is something you might consider only if you intend someday to slide down that slippery slope of performance modifications where you would benefit from a larger intercooler. If you're pretty much staying stock everywhere else, then the stock IC will work just fine.

My stock IC is spending a lonely retirement on the shelf in my shop. Actually, I'm holding out for the day when the 930's become rare breeds and someone is just itching to return one to stock configuration....so I can sell it for $700.

You need the manifold for the 3,3 because there is a different angle from the 77 to the 78 intercooler. Its usually just easier to buy the whole injection system and slap it on.

As Bruce is saying, you need an intercooler made for a 76/77. Andial used to make one and B&B might but I do not recall.

I thought '76-77 did not have intercoolers at all?
Why could you not, just simply get the top section of a '78-'79 3.0 turbo intake manifold and fab from there?
Hell, once you get the intercooler connected to the intake manifold, it's just tubing & hoses from that point on,

That's what I figured. A stock intercooler is better then none at all, and I don't plan on going for more power. At the very least I'm sure I can make my $ back.

I turbocharged my BMW 535is so I'm used to making things work.

I probably have a dozen stock intercoolers stuffed in a corner of the shop. They are worth about what you paid.
This is not a matter of buying the later up-pipe and down-pipe, the stock '78-on 930 intercooler will not fit the '76/7 intake. The angle of the throttle body is different.

The 930 1975-1976 and 1977 didn't have a stock intercooler! They had, US models 245 BHP and EU 260 BHP. The first Turbocharged 930 with stock intercooler and 300 BHP came in 1978.

260 for a 3.0 compared to 300 for a 3.3 as a starting point. Considering the 76-77 is about 10% smaller that is not that much difference per CC. Most often the 3.0 turbos are lighter cars and have better weight distribution. Thus, not that much of a performance potential difference without an intercooler.

To me one of the best things about a 76-77 is the rear wing. It is just a shame to have to remove it so an intercooler can be installed.

I believe you can shoe in a custom intercooler that can fit in the spaces available if needed.

Another approach is to keep the basic car intact and representative of its special status and work to make it run as efficiently as possible without an intercooler. There have been many low boost cars that are very fast.

Cams, headers, low restriction muffler, more efficient turbo (larger compressor wheel), ideal AFR's and ignition can all add to HP and probably get one up to well over 300hp.

On a 3.0 turbo on could pick a cam that moves the efficiency range higher on the RPM curve. Something like an improved Group B cam. The 3.0T has an advantage over a 3.3 in that it has a stronger bottom end and can operate on stock components up to 7300rpm without issue. Moving the peak TQ curve up the rpm curve 10% can add 10% hp.

Another way would be making it bigger. Larger cylinders can get it to 3.2 or more easily. One of my dreams would be to drop a 993 crank in one of these and use a set of Nickie's cylinders and make it a 3.8 (3.75) but leave the outside stock, bump the compression and actually lower the boost. Could end up with 400hp and great low end throttle response.

Twinplugging could help and be something to consider to.

My thought is why add all that extra weight and loose that beautiful tail and special identity. Just polish what you have and make it the best it can be.

Just my two cents.
