I have a 1973 914/4 2.0 which is is partially disassembled.
It came with two hot air blowers: Single Port - Working Motor In 1973 there was apparently a switch between the dual outlet blower to a single outlet with a Y pipe. I was thinking I would like to use the dual outlet one so I thought I would swap in the working motor. Two questions: 1) Does the dual outlet unit provide better heat flow through the heat exchangers than the single outlet with a Y connector? Any pointers to pictures of each type mounted/hoses? 2) How to remove the motor: Removed the 6 screws on the motor flange Thanks in advance Scott Attached thumbnail(s)

Thanks for the info and detailed review of the two setups/history.
I may just go with the splitter kit from Auto Atlanta to split off my working single port blower and drive both heat exchangers. With my wife using the heated seats in her cars, even when it is 35C in the summer, I can use all the heat I can get. Scott |

Scott Thats how mine is set up, i do like having the heat coming out of both sides if you have a passenger. My car is a 75 the fan works fine it is the single outlet with splitter clamped on the end. my only issue is in the summer i cap them off and disconnect the lower tubes because the flapper box seals are not fully sealing so hot air gets past even in the closed position, not desired in the 90 degree heat |
