Why not install a 968 intake manifold? Ya, I know, the 968 intake manifold is designed to work in conjunction with variocam, but it will still have an effect. The 968's torque comes from the intake anyway, not the variocam. I wonder how it would be on a 944S. The valves are smaller on this car too but still...?

My 1985.5 NA is a daily driver. odometer stopped 5 years ago at 191,xxx miles
Just drove 300 miles today at 60-80 up mountains. 1000 miles ago did TB/WP and shaft seals, rollers preventative.
That said, the guys doing 968 engine swaps make over 200 hp in NA format, which is kuel.

the manifold is designed to work with the sheer size of the engine to make torque down low. the variocam doesnt switch on til like 5000RPM iirc which optimizes breathing and increases HP.

968's variocam is designed to increase the low speed torque output
read a book about it

the varioram physically changes the length of the air intake depending on engine RPM.
variocam alters valve timing so that the intake valve stays open longer and overlaps a bit with the exhaust valve.
there is no shortage of torque in a 4-cylinder engine displacing 3 litres.

Yes...that I've seen. And my understanding of variocam is just the last quote, not the first.

notice i said varioRam, not varioCam.
varioram is a variable length intake manifold on the 911 series cars starting i believe with the 993.
there are intake runners inside the airbox ontop of the engine. the runners slide into up or down positions depending on engine load and speed. the runners slide into place over the intake ports, causing the air to have to travel a longer distance which increases low/mid torque. once the car gets to a certain engine speed among other factors the runners pull away and air goes straight from the airbox into the intake ports. ill draw a picture really quick.

Dont worry about power...something will always be faster than you anyway. Do some bolt ons, make the car fun, and dont worry about it. If you really want to get crazy, strip the car. 200 hp and 2500lbs is a lot of fun.
1 of the funnest cars ive ever owned was a 1990 BMW 325is... it barely had 200hp, but it was lightened and had an LSD. I drive a modded 951 now, but I still had more fun in that car.

I'm not worried about being the fastest out there or anything like that. Just a little more pep to make my everyday driving fun. Some previous cars I have owned were a 72 Camaro, 73 Duster, 75 Nova, 94 Trans Am. All had v8's, all had modified engines, the Camaro from the ground up.
The 944 I have won't compete with any of them straight line and I'm ok with that. But I just want to have a bit more fun than where its at now. Just changing the plugs and cleaning the fuel system did it a ton of good. I've decided I will just do some boltons through the winter...new ignition, new exhaust(I have a loose baffle), a chip. When I rebuild it I will add a lightweight flywheel and maybe a lightened crank.
I think that should get me about where I want to be including shedding some body weight. I'm pulling the ac parts (I don't like ac anyway), removing the backseat and carpeting it, maybe some lightweight front seats, etc. I also hate the stock wheels so I may keep them for my snow tires and buy some nice ones for summer...I need to weigh these to see how much they are so I can try to find some lighter ones if possible....trying to shed all that rotational mass. I've worked with carbon fiber and fiberglass a lot so I might replace some parts with that.
Heck I could even diet! I could stand to lose 20pounds
And I think my funnest car was the Duster. Unlike the other cars on my list it was a piece of crap.....which meant I didn't mind driving the heck out of it. I had a lot of fun in that car and that was the weakest one of my v8's.

True, but this was F18Rep talking. If anyone can keep a 944 running, he can!
Personally, I agree with the above poster who recommended fixing the car up and flipping it. You got it for only $2,500 and let's face it, the biggest appeal these cars have is their handling on twisted roads and steering feel, but coming from V8 muscle cars, I have a feeling the NA motor will never be "fun" enough for you, so you're probably better off gettng a 951 instead.
Having said that, the 944S is a fairly rare model in the 944 line. I think you should keep working on getting the car to run normally in stock form by replacing fluids, filters, plugs, solving that miss, etc., before moving on to power upgrade considerations. And by all means, keep the A/C and make sure it works. Big plus when selling the car!

The beauty of these cars lies in the handling, balance, and build quality. In this regard they are exceptional and were essentially peerless in their time.
There is absolutely no need for additional power.
