I am running a 1999 996 3.4 motor in my 1998 986 ( original 2,5). I am using a 987 air box with 3.5 silicon tubing and a stock 996 throttle body and MAF. I had my 986 5.2.2 DME flashed as a 996 ROW. Car runs strong and everything works including my Top. Car is really quick !!!
I ran into trouble when I combined a 996 analog gauge cluster (with my 986 cluster mother board) and installed them in the car. My 986 DME which thought it was a 996 ROW could not talk to my gauge cluster that thought it was a 986 cluster. I had to re-program the 93c56B flash chip in the 986 mother board to make it think it was a 996 mother board and all now works perfectly. At no time in this process did my top stop working. Hope this helps some!!
