Hey dpranti, I was wondering where you are getting the HP ratings of the 85 32 valve motor, everything I have ever read shows the 85 with 284hp. I`m not saying you are wrong, just curious. I spent alot of time reading about the history of the 928 before I bought one and I`ve not found any info that ever shows the 85 with more than 284, atleast a stock 85 with no modifications. But I do love info reguarding the 928. Would you mind sharing where your info is listed, there may be other specs I`d be interested in as well. Thx, Toofer
1) 928 Workshop manual Volume I p. 0.27: Max power kW/HP 215/292
2) 928 Technical Specifications Booklet p. 8: kW(HP) 215(292)
3) 928S USA '85 Information Booklet (WKD 491 721) p. 2-3: 288HP @ 5750RPM
4) 928S USA Servicing, Assembling and Adjusting Booklet '85 (WKD 491 820/821) p. 2: Max. Engine Power: kW / HP 215 / 292
5) https://www.928gt.com/t-928engine.aspx
I'm surprised you didn't find any sources of accurate info. Trust me, it's either 288HP or 292HP; I just take the average and call it 290HP

Saw a Guards Red w black '84 S today. Paint ok for it's year, interior seriously !@#$'d up, oil leak from right cam cover and power steering line, oil pressure bouncing between 1 and 1.5 bar while idling. Tranny a little loud ( he says they may be the carrier bearings ) but not crunchy. Upper and lower ball joints toast. Wheel bearing nuts could use some lube and retightening. Sleeping on it. Question, what should the oil pressure read at idle?
It took me 10 months to find my '86 8 years ago. My best advice would be to be very patient and wait for a nice and decently priced '85 or newer model.

dpranti, I checked your sources, your absolutly correct. The 86 did have 288 and the 85 was 284. You must own an 85, don`t get so steaming under the collar you`ll have a stroke or something.

It took me 10 years to find a 32 valve 928 that I could afford, that was NOT automatic. I finally found one in long island, dumped $10k into it and toasted a cylinder head after 98 miles by some FREAK ACCIDENT [head rebuilt AGAIN and about to install it in a week or two]...See grommet in search. The second 32v car I found 3 months later in Ny (both came from NY; good place for deals!) I paid $2000 for my meteormetallic car and drove it home that day. Needed timing belt, seals, gaskets, relay, and some tlc, but the car is in good shape and I drive it daily, it's my only car actually (besides the other 85). Needs some suspension help, but I think I got an insane deal! They're out there....keep looking.
