X-pipe, fresh 02 sensor, sorted my injectors at WitchHunter, air pump delete, PorKen tensioner, 55 lb fuel pressure regulator, PorKen chips. While I was tearing into it, I also replaced the 19-year old timing belt and put in a new water pump, thermostat, fuel lines, vacuum lines, and some other crap. Also swapped in good console switches, bulb check unit, and a few other goodies. Car has original plug wires, caps and rotors, and was missing a spoiler. All that stuff is on the way.

What, you mean like these? Saturday...

Of those things you mentioned, conventional wisdom would say only the X pipe and the chip would add more power over stock and then it would be only marginal.
Do these 928 engines really respond that well to minor changes?
What was the stock HP and did you have it dyno'd after the changes?
Not trying to be a smart ass, just curious.



BTW regarding the previous post about alina and the "can I turbo an N/A 944", I got quite a bit of skepticism about a dozen years ago when I announced to the Porsche world that I was in the process of turbocharging a 2 liter 914 type 4.
To this day there's a standing inside joke, "you can't turbo a 914".

But I did it anyway and it worked. 7 to 8 pounds of boost, non-intercooled, stock internals, and it put out about 75% more power than stock. HUGE difference.
It happily revved to over 6000 rpm without falling off at all and it did it reliably. Type 4 owners know they typically fall flat on their faces at around 5300 rpm give or take.

You can turbocharge any engine no matter what design, as long as you keep the boost levels reasonable for the engine and you don't let it go lean or ping.
The people who say otherwise don't really understand turbocharging or internal combustion engine physics.

Of course if a turbo-tard decides to run 1 bar on an engine that can't take it, bad things will happen.
That's why you have to match the boost and map to the engine.

Sammy, no one has ever said you can't turbo an NA944, just that it makes more sense to go buy a factory turbo....

Yeah Sam, If you can unplug the exhaust, a set of chips can add a lot to the engine, especially the early 32 valve cars, where they left a lot on the table. What people tend to forget is that with 5.0 V8, there is just a mountain of torque everywhere in the rev range. Even an unmodified 270 HP 85 is going to push out over 300 foot pounds of torque. Where they get hung up is upper RPM breathing on the exhaust side. With forced induction, even at 4 PSI you are going to be pushing 400 HP and foot pounds - Pretty serious cars.

I guess in many ways the 911 is the better Porsche, but the 928 is the better car. Put one on steroids and it starts to resemble a Viper.
