Not too sure on the models. I know the very fast one is 5.? litre V8. There was a load of them at Santa Pod last time i went. the fastest was a 14.8 - 17 sec 1/4's. I think they are very much a GT like the old 6 series BMW and XJS ......
EDIT: Some info.
n 1989, Porsche ups the ante again, this time delivering a 'serious sporting machine for the solvent'. The GT is a special version featuring a revised 5.0 liter 330HP V8, sport suspension and all new seven-spoke Club Sport rims (note 1), the rears the widest yet from Porsche measuring 16 x 9" wide. As such, the GT comes only with a manual trans. Visually imperceptible but an improvement functionally, the shiftrod is shortened 1" from the manual S4. Driver and passenger-side airbags introduced and Porsche becomes the first to make them standard across the model line. New low-pressure tire warning system is standard.
From 959 technology, the 928 GT is fitted with an electronically controlled liminted slip differential. The LSD has a progressively lockable multiplate clutch installed with the rear differential (note 2). A computer monitors wheelspin and clutches the affected wheel. Also new is a tire pressure warning system utilizing a pair of sensors integrated into each wheel. The wheels themselves made a change from the original Club Sport wheel in model year 1989 to the forged Design 90 style beginning in 1990. Price: $76,500 (note 3)
Exact 928 GT production figures are unknown to the author but have been guesstimated as follows:
1989/90 - 50 US cars; 1990 - 100 US cars; 1991- ? 1992 - no official 928's produced, see the 1993 928 GTS.
(In response to market, Porsche introduces the hotter engined GT mid model year in 1989. Thus there are both manual and automatic 1989 928 S4's. For model years 1990-1991, the 928 S4 continues on as before but comes only with 316hp and the 4-speed automatic)
(note 1.) Club Sport see 928 S4 info (note 2.) Motor, August 1988 (note 3.) Car and Driver, July 1990
Year Type HP@rpm Engine Serial Number Chassis Serial Number
1990 928 GT 326@6000 * need factory clarification WPOJBO920LS860001-0518
1991 928 GT 326@6000 * need factory clarification WPOAA292xMS810001-0448
table source: The Porsche Family Tree, published by the Porsche Club of America
* the engine s/n from the PCA tables have been omitted so that we may verify them with Porsche. If your need is immediate please purchase the tech spec booklet. other note: peak hp has been recorded at slightly higher rpm value of 6200 rpm. This page will be corrected...note: chassis numbers given above shared with 928 S4 cars
note: 928 GTs were available beginning with model year 1989. (Updated numbers will be posted)

Subject: 928 GT identification
PMJI:
Barring any original car documentation which denotes serial numbers, the
only way to authenticate a GT will have to come from the Certificate of
Authencity ie. the cardex info. (This will rule out any creative engine/trans/dash swaps).
Code 639 or 637, denoting GT, may not always appear on the build sticker in the trunk for
some reason (it doesn't on my GT and a few others have responded same
here on porschefans). The presence or lack of code 474, sport
suspension, is no indicator as well (my black Boge equipped car lacks
this also !?!).
So, what the cardex will tell you (from my experience with the 1990
model) is:
VIN
Engine serial number (ex. 85L00855 - all GT engines begin with 85)
Trans serial number (ex. 3L00788)
Paint code (ex. Baltic blue metallic C7C7)
Interior code (ex. Silk Grey Leather, Blue Leather, Leatherette QQ)
Optional equipment
and curiously enough... the 928 GT is identified by Porsche only as "928 S4"
This same anomaly may apply to Club Sport / SE editions as well.
If anyone has info on shortcuts to getting the cardex info please let us
all know as one won't always have the luxury of time for snail mail when
shark hunting!
For those in the field shopping right now, verifying engine code M28.47
and trans code G28/55 (note these are 'type' not serial numbers) is a fairly
safe bet that you are indeed looking at a real GT, but again, only the factory
cardex will provide the serial numbers.

Phil and Paul,
Phil, I know you prompted me for a response on this topic earlier in the month
and I didn't respond due to my travel schedule. Here's my .02 on this topic.
Besides the identification numbers on the engine and option codes there are
some esthetic differences. The most obvious on an 89 GT are the wheels. They
are the forged "Club Sport" alloys that were the same basic style as those on
the 944 Turbo S's and appeared only on the 89 GT(club sport - ROW) models
only. The only other exterior visual is the twin exhaust outlets, 1989 S4 5
speeds (like mine)have a single outlet and the GT's have dual outlets. On the
inside the only difference would be the length of the shifter. In a GT it is
the shorter shift lever while S4's have the longer shift lever found in early
928's. Of course we all know that Porsche has been known to throw curves from
time to time and use whatever parts happen to be handy so this is a rule of
thumb.
I have attached a scan of an 89 GT that I recently considered trading my S4
for. Notice the wheels and the option sticker codes. The sticker has the
GT(639) option and the sport supension(474) option.

Depending on colour and depth of history file a good/mint 928GT manual could fetch up to £18k. There are buyers out there for this car.
So if you can buy it "cheap" do so, just to experience what a 1990's £80k supercar feels like.

Impressive! I've never owned one, just going on reports/reviews (and re parts, the experience of a former workmate who put his through a hedge backwards).
