924S Crank horsepower limit

What's the limit of crank horsepower 1988 924S (160stock) will see? Anyone have good websites with aftermarket parts? Are headers, catback exhausts, downpipe, high flow cat, light weight pullys, light weight drive shafts, light weight flywheel, cold air intake, throttle body, intake manifold, camshafts, ecu upgrades out there for this car?

I currently drive a 240sx which is a fun car. I just want to try something different. Afterall, how do I know the 240sx is a great car if I never experience something different? I hear mixed stories about 924 reliability. Some say its great, some say Porsches are terrible. However, Porsches are high performance sports cars built with reliability in mind, and certainly more reliable than say a Lamborghini or Ferrari. Will the 924 be decently reliable? Another car I'm looking at is the FC-RX7 (like 91) non-turbo. The fact it's rotary scares me away with the reliability issue and finding someone that can work on it will be difficult (more difficult then finding someone to work on a 924?) Will a 91 rx7 be as reliable or less reliable than a 924? I like the RX7's perfect weight distribution. How are the brakes on the 924S? How are the 924S's at their limit? The 240sx's rear end kinda comes out a little with a controlable oversteer. Fun, but I'm sure it's not the fastest way around a track.

Final question, does the 924S come with an LSD?

Buy a 951 (944 turbo) if you want something fast and upgradable. A 924s is a good porsche starter car but not something that youd want to spend money upgrading. Reliabilty depends on too many factors. From owning 2 944s I have found that they are pretty reliable as long as you keep up the mantinence ...im sure its more reliable then a rotary engine seeing as they die around 100k miles. Brakes are of course great, 4 wheel disc brakes was nice to have back in the 80s. At a 924s' limit?? Whats that mean ...banging up on the rev limiter, cornering hard? what? LSD was an option.

whoops I ment cornering hard. are they predictable, easy to drive? Great grip? The 240sx is more of a "drift" car, but it seems like the 924,944 and 240sx are very much alike.

The 3rd gen Rx-7 and 924s are two completely different cars.

The 3rd gens have lots of problems - I know a few guys who have them and they are not daily drivers. As beautiful a car as they are reliability really suffers. And finding compatent rotary mechanics can be real difficult. Stay away from the 3rd gen unless you have deep pockets. the cost of the car is just the beginning...

As far as weight distriburion, the 924/944 are 50/50.

Getting power out of a 924/944 n/a is not easy, they just don't respond well to horsepower upgrades. Do a search on this site and you'll see what I mean. Short of turbocharging, supercharging or nirtous, I doubt you would be capable of creating the kind of power that would stress the crank. Adding "headers, catback exhausts, downpipe, high flow cat, light weight pullys, light weight drive shafts, light weight flywheel, cold air intake, throttle body, intake manifold, camshafts, ecu upgrades" will only lighten your wallet without making any real noticable gains in power or performance. The exception may be a chip from FRwilk, again do a search but the difference isn't going to be the kind you're looking for...

Bottom line - you want power buy a 951. You want a nice driver get the
924s/944. Otherwise you might want to look elseware...

are you asking what the max HP is that the crank can handle or the max HP the engine can deliver?

so the stock 924 exhaust isn't that restrictive? I modified my 240sx a little (cold air intake, catback exhaust, racing headers, highflow cat) and noticed alot of power from a catback exhaust, thought the stock catback was very restrictive. I also noticed much power from a cold air intake. Ram air didnt do anything but once i got the cold air extention the motor it got very responsive at 3-4k rpm. anyway heres a picture of the stock 240sx exhaust:


EDIT:
I'm asking the max horsepower I can get with basic bolt ons on the 924S motor. 200 crank would be nice (165-170wheel horsepower) but that's hard even with the 240sx.

Oh, I might have mislead - I thought he was asking the max HP the crank can handle - looks like he was asking max power the engine can handle.

"max crank HP" (as in not at the wheels, but at the crank)

I think you'll be hard pressed to get a true 200hp with bolt-on's, but I could be wrong.

At any rate it would be pretty expensive.

that's what I thought, too. hence my question and this reply planned earlier:

the 88 924S has the 944 motor in it. the crank in the 944 motors is probably the strongest part in them besides the block! it should handle whatever HP upgrades you plan on making. unless of course, you're planning on doing some kind of all-out twin-turbo, NOS, etc. etc. conversion, at which point a lot of other things would fail long before the crank

hmm maybe you guys are misunderstanding me. I'm asking what's the most I can get with boldons from the 924S motor? Another car i am looking at is the BMW 325is from 88? The guys on the bmw forum said don't expext more than 200hp crank with the motors n/a.

No. We don't misunderstand you. This question is asked very often.

The answer is: If you want a fast 944 get a turbo -- 951.

You will spend twice the purchase price of a 951 to get almost as much HP out of the 924S. Please include the 'S' as a '924' is a pre 944 car.

How much horse power do you get from your radiator cap? Wouldnt a white cap produce more horsepower since it will reflect more heat off it therefore cooling the engine more giving it more horse power? Id guess it would give around 15 horse but im being modest here.

nope, since the heat radiates out through the radiator cap, a white one would retain heat. we've experimented with bakelite-plutonium units that yielded net increases in hp by as much as 27. equipping the system with a reverse-osmosis return valve also adds about another 12 hp. but the price....

I was, like, thinking, like I could like drill holes in the radiator cap to lighten it and wouldn't that be totally. like, awesome?

Actually just eliminate it all together. The air would cool it better anyways!
