I bought this from someone on the list 10 years ago or so. I have it listed for sale and the buyer wanted me to verify what was socketed on the board. I opened it up and this is what I found. Looks like a ...593 program, which should code to a 90 2.5 TI correct? What about the board, does that look like a V-6 board with the additional heat sink? My R/T SBEC only has 2 heat sinks, if that's the case then V-6 SBEC's will work as spares?
