i ready to sell my 1987 944S and hopefully get a 1989 944 Turbo S but i have a few questions:
does the turbo s still have the 50/50 weight distribution, and does it have the same handeling, because i have heard (not sure if the guy knew what he was talking about) that the 951s dont handle well
other than the 3.0L engine, are there any other differences between the Turbo and the Turbo S? S2?
Also, would the heads off of a 1987 944S fit on the turbo or the 3.0L turbo S?
thanks alot,
Frank

 

DIFFERENCE BETWEEN (turbo)= 215 hp up to 1988 (turbo S)=247 hp 1988, turbo 89-91

Engine:
TS has larger turbine blade and higher a/r ratio, same compressor blade and more boost (T= k26/6, TS= k26/8 )
TS has different computer In addition to changing the turbocharger a different DME (Digital Motor Electronics) control unit is used with different fuel and ignition curve families. A different knock and charge pressure control unit KLR is also used to increase the boost to 1.82 bar absolute (11.89 psi boost) an increase of 0.07 bar from the 1.75 bar absolute (10.88 psi boost) of the T
TS has 247 vs 217 hp for T and higher torque for TS
TS has baffled oil pan and extended oil pick-up (this was an upgrade on T and TS from late 87)

Suspension:
TS has koni adjustable shocks and sport suspension with larger sway bars and etc
TS has adjustable spring perches,
TS has body structure strengthening brackets,
TS has stiffer bushings in suspension parts,
TS has higher rate springs(190lb/in TS front vs 160lb/in T front)

Brakes and Wheels:
TS has larger stock tires and wheels
TS has huge brakes (big blacks)
TS has club sport wheels
TS has ABS standard,

Drive Train:
TS has transaxle cooler- this is not peculiar to TS as there were coolers in other years
TS has limited slip differential with thicker plates,
TS has hardened 1st and 2nd gears and hardened transaxle shafts

Other Stuff:
TS has 10 speaker stereo,
TS has split-back rear seats
TS rear track is 1" wider

In short, the turbo s cars are more full-out racing machines than turbo cars and were developed with data from the turbo cup road racing series in Europe.

Drive a turbo and a turbo s and the differences are obvious.

thanks alot..
i like going fast, and want to upgrade to a different 944, possibly for drag and definitly for open country and winding roads.
Im looking for a reccomendation over an S2 or a Turbo S.

some say the naturally aspirated S2 is the way to go because it has the 3.0L and doesn't need the turbo. would i notice the lessened hp and different suspension in the S2 compared to the raced out 1988 and up Turbo S (simply "Turbo" after 89) or is the 247hp Turbo the best bet?

Drawbacks im considering: Apparently, the S2s have a chain tensioner in the head for the cam that will break and is an EXPENSIVE fix.

Another thought..an S2 with a turbo kit. Already at 208hp, a turbo kit (if available) should promise another 50hp, plus you have the 3.0 16valve motor

im pretty undecisive right now, but am looking for some more knowledge before i go searching

thanks for any help..

 

If you are ever going to drag, forget any Porsche 944 based car....you will dump the clutch twice at 3000 rpm and replace the clutch ($2500) and the transaxle ($2800).

Turbocharging either the S or S2 will require you to replace and modify so much stuff that the original cost of the car will be a pittance.
