How much horsepower does the car generate without the Turbos?
I'm not sure if the car would even function without the turbos..heh..but how much horsepower does just the stock block make?
I know on my WRX it's about 110 to 120hp...
I tried doing a search but couldn't find anything.

Not very much. I would guess not much more than the 86-88 13B with 146. The 89-91 13B N/A has higher compression rotors. So maybe 150? I do know that on a dyno run with a boost leak (damn i/c couplers), I only hit 190 to the wheels with downpipe and cat-back exhaust.

Stock FD3S with turbos off line: 180. More than enough to drive around town with.
Completey worked race engine with no turbos: 300
My golf cart, 3. But it's electric!
Average human: 1/4.
Don't you feel.....inadequate?

to run N/A, I think you need to do the following:
1. raise the compression.
2. tune the map to stock.
without these two, the car would run less HP than N/A.
I think to accomodate turbos, the engine would need to have lower compression. And now its tuned rich as well for turbos, so to run N/A you need to lean out the A/F.
I would think you can get something close to 200, for properly tuned n/a engine.
I dunno...

If you removed the turbos from the car, you should get something around 150HP as others have said. Consider that the intake pressure is 24.7 psia (10 psi boost) to get 255 HP, the HP at 14.7 psia (atmospheric pressure) calculates out to be 152 HP. That formula does not account for temp differences, etc., but it seems like a reasonable estimation.

A stock N/A FD engine comes with 190 horsepower, then with turbos of course it generates 255. My dad's first getn only had 110 or something like that. Kinda funny, but it was still fast!

Average human: 1/4hp.
Actually, the average human makes considerably more than that. I believe it's more like 4hp or so, and of course more or less depending on the person themself.

Horsepower is the amount of work that the average horse can do in a minute. James Watt, back in the 1700's found that an average horse could do 33,000 ft-lbs of work in a minute. He came up with this when he was using horses to pull coal out of a coal mine. I'm sure a human couldn't even come close to this.

that is the older definition. Now a horsepower is something different, something like how fast you can go up a certain distance over a certain time. Just put it this way. Do you honestly think that a 200hp engine is as powerful as 200 horses? I personally think not. Or say your lawn mower is 5hp, i no for sure it isn't as strong as 5 horses.

Unless I am mistaken, there are no NA FDs. So there are no 190 HP NA FDs, OK?
Watt noticed that a horse could lift some amount of weight some distance in some time period. That isn't really a test of the horse's entire dynamic capability, so it is at least conceivable to me that a human might be able to produce more than 1 HP in some set of circumstances. It seems very likely that a horse can make more than 1 HP as it gallops away from a stop. A horse can take off faster than a 2 HP go-cart with enough ballast weight to equal the weight of the horse, for instance.
This whole discussion is pretty academic -- unless you literally remove the turbos, you aren't really running without them.

No one in their right mind would knowingly disable the turbo system to run their engine "naturally aspirated", and anyone who did so would find out quickly how well the turbos hold up free-spooling without the backpressure of the intake system.
The car will run "naturally aspirated" well enough to move around the driveway or in the shop if you had to, but that's it. It's nothing you'd want to take out and drive around town, and if you tried to run the car hard in that configuration, you'd quickly over-rev your turbos and more than likely cause some fairly expensive damage.
Furthermore, since the rotors in the 13B-REW are 9.0:1 compression, less than that of the naturally aspirated 13Bs (9.4-9.7), it would more than likely make LESS power than an NA 13B, especially with the restriction of the turbos and exhaust manifolds in the exhaust.
The 9.4:1 NA 13B ('84-'88) was rated at 146 horsepower, and the 9.7:1 NA 13B ('89-'91) was rated at 160. 190 horsepower from an NA 13B-REW?? I don't think so.
