Installing a bigger intercooler is a great idea. Anything you can do to take thermal stress off the engine is an improvement. First thing I did was to install a larger B&B intercooler on my 1979 930 and then a Carrera oil cooler in place of the trombone in the passenger fender.
Also, this allows later improvements like more boost and k27 turbo which will need the safety of the larger intercooler. You can always go back to stock too as it uses stock intercooler up pipe and o-rings.
The B&B is another option to the Kolken and it fit well except for some machining on the attachement boss to the fan housing bracket which was way off center. You will need to make sure you get the intercooler shrouding to the tail done properly to seal the intercooler to the tail so all the air gets pulled thru the cooler and not arround the edges of it.
Seeing that you live in Oakland county in Michigan, you will likely see hp dropping off while hammering on the I-696 "autobahn" with the stock intercooler. With the bigger B&B cooler I can run flat out all day on that road. Though I did not recommend speeding in writing.
