89Cab

Hope this helps.... In the 911 Carerra (non turbo)- the 915 trasmission was replaced with the G50 transmission in the 1987 model year. The same year had a few other differences in the DME that bumped up the HP and Torque. In the Turbo 930's the only year that the G50 transmission was included was the '89 model year. You may want to get your hands on the Porsche Red Book which lists all the changes and options for each model year. Some/Most people swear by the G50 transmission- some people don't think there is much of a difference for practical driving. A few people do like the 915 transmission better... I've driven both and I think there is a difference with the 950 being less sloppy and feeling torqier (is there such a word?)- especially at lower RPMs in 2nd and 3rd- but that might also be DME related. That said, it might not be a make or break thing for you... Also, some early G50 transmissions had some very minor issues with the fork which gets an upgrade when you replace the clutch ... You should read up on the G50 transmission and definitley drive both before you buy...see if it makes a difference to you because that's all that counts.... the extra $ you might have to pay for an 87-89 may not be worth it to you. More important is the mileage and condition of the car. Try to have a PPI performed by someone who knows Porsche's inside out. Maint records are a plus but a leak down test will tell you alot more. I believe 84-89 Carerra's all had 3.2 engines- they did not have the problems with the airbox- and that's a quick and reportedly easy fix anyway by adding a popoff valve - the 2.7's were much earlier cars ... they were problemtic because of a problem with the studs pulling out when the engine heated up- but there are fixes for that as well (albeit not inexpensive) and the cost of the fix is usually reflected in the price between a 2.7 and a 3.0.... jim
