2.5 HP Differences?
Hey guys,
There was an 87 or so Porsche 924 in the junkyard. I was looking to pull some parts off of it, but mostly anything worthwhile was already gone. I was doing some reading on the net, and I read somewhere that the Porsche 924s around 87/88 had 160hp VS the 143hp that my 1984 / 944 supposedly puts out.
What is the difference between these two seemingly identical drive-tranes that one would put out more power? Does one of them have higher compression? Is there something else about it that allows it to produce more power?
Thanks!

From Wikipedia:
In 1986 the 924S was released. Porsche realised with the 944's prices increasing with new standard features and options, they were losing their place as Porsches entry-level model car. While the 924 had always been available in other markets, Porsche decided to re-introduce the 924 to the American market with an initial price under $20,000. The 924S had an old-spec 944 engine and drivetrain but with a normal slim 924 body. It also retained the original 924's spartan, VW-like interior. In 1987 the 924S Le Mans (or Special Edition) was made available in limited numbers with a 944 spec 163hp engine, uprated suspension and cosmetically upgraded interior and exterior. This special 924 had manual windows, no sunroof, and no air conditioning to save weight, although you could order one with air conditioning if you so wished.
In 1988, the final year of production for the 924S, the power for all models was brought up to 163 hp (122 kW). This made the 924S faster than the base 944 due to its lighter weight and more aerodynamic body. Due to unfavorable exchange rates in the late 1980s, Porsche decided to focus on upmarket models. They dropped the 924S for the 1989 model year, and stopped producing the base 944 later that same year

'85.5 - 87 had 147hp, slightly more compression over the '83-85 which were rated at 143hp.. The '88 had slightly higher compression and had around 155hp or somewhere in that area. The '89 had 163hp with the 2.7L.
I think thats how it goes.

I can probably get that 924 motor for $100-$150 bucks. Should I snag it from the junkyard? It has a hatch / 3rd brake light, so I know it's an 86+ at the very least.
Thanks!

Facts.
This applies to US spec cars (Euro spec cars are different)
924 - 1982 and older All used Audi sourced 2.0L engines. Hp varied by year
83-85.5 944
9.5:1 Compression ratio fatory rated at 143 hp SAE net
Steel front suspension & steel rear suspension
Wheels were 23.3 mm offset 15x7 Cookie cutters with optional 15x7 fuchs and 15x8 fuchs 10.6mm offset rear.
85.5-86 944
9.5:1 Compression ratio factory rated at 147 hp SAE Net. Slight change in the exhaust cam durations could account for rated hp increase or it could be due to a change in conversion from DIN rating system that is Used in Germany. I believe all the 944's were 150 hp DIN rated, but this is of little consequnce since in europe all the car had higher compression with 163 DIN hp.
Aluminum Front & Rear suspension
Wheels were 23.3 mm 15x7 Phone dials standard. Not sure if Fuchs were optional or any 16" optional sizes.
87 944
9.5:1 Compression ratio - 147hp SAE Same engine as in 85.5-86 car with minor updates. IE auto tensioner and similar non hp improvements.
Aluminum Suspension front and rear
Late offset wheels 52.3 mm phone dials standard in 15x7
87 924S
9.5:1 compression ration egine. EXACTLY THE SAME ENGINE as the 87 944. 147hp SAE.
Steel front suspension & 86 944 aluminum rear
Wheels were 52.3 mm offset in 15x6 to clear the narrow fenders. .829 ratio 5th gear inplace of .729 of all the 83-87 944 models.
Interior was similar to 83-85 944's, but with different colors. (no brown)
88 944 & 88 924S
10.2:1 Compression from a small dish in the piston. Factory rated at 158 hp SAE and 160 DIN. This was the "world" motor and was the same in all markets.
87 944 suspension on 944
87 924S suspension on 88 924S
All cars had short .829 ratio 5th gear.
924S M030 sport had bigger sway bars, smaller driver's side mirror and no pass side mirror. Also roll-up windows. All cars to my knowledge had AC.
Note the 86 924S was never imported to the US although many 924S models were sold in late 86 as 87 models. My 87 924S parts car was a car that was built in 86, but sold as an 87 model.
