besides, your s2000 doesn't have TORQUE, and to make all that HP, it has to rev to about 900000000000 rpm
1. I love the s2000. Its my dream car.
2. At least the s2000 is able to rev that high AND you still get 200+ hp
3. It is more fun to drive a slow car fast then vice versa. Don't believe me? Check this vid out

I have a Torsen LSD and I love it. I don't notice much difference on the street but when I autocross it makes a big difference.

Haha, good job on bringing it back on topic!!!

Although to bring it back off again really quickly, I have to tell you guys......


YOU WILL NOT SEE 250WHP ON AN N/A 2.0 LITER SVT ZETEC ENGINE. Show me documentation of its existence. Turbo'd, yes, Supercharged, with a lot of upgrades and tuning, yes. Nitrous, sure. N/A...absolutely not.

I don't even think you could get that kind of power out of ANY N/A 2.0L engine.

Please, be my guest and peruse these (note the highly modified engines):

http://www.focusfanatics.com/forum/showthread.php?t=101162


Also, listen to John/03OrangeSVT. Believe him when he says something the first time.

Also also the S2000 is one of my favorite cars but it is by no means the end all of automotive engineering and on top of that, again, should not be compared to the SVT Zetec.

I love that..."ONLY 70-80 hp more than stock." Haha. That may be nothing on an LS6 but dude, give me a break...that's 46-53% MORE power than stock, and you think you can get all that power just by porting and tuning and opening up the exhaust!? phhhhhhhhhhhhhh...

One more thing--the S2000 does NOT have a 2.5L engine, it has a 2.2L engine--either way it is a larger engine with more displacement and is inherently going to make more power than a 2.0L engine mod for mod.

(I'm chilled out--just don't be spreading around false info or inflating numbers to a ridiculous height...most of us are realists)

LSDs!!!

Are you guys talking about 200+ crank hp using pump gas, because if you are forget about it. The SVT already has aggressive cams & high compression. You could increase compression to 11:1, but you would need at least 93 octane & a very good tune to be safe, but still won't break 200 even with all the bolt ons & a p&p head. Anything higher than 11:1 you would need to use 100+ octane. Honda did claim 240 na crank hp with the early 2.0 liter s2000, but that engine had dual cam profiles, vct, & a lot higher VE than the zetecs. The RWD s2000 was light enough to scoot to 60 in the lower 6 sec. time with less than 140 ft/lb of tq. The only way a zetec can see anywhere near 200 na is the 2.3 stroker, FR or custom intake, 70mm TB, & a hell of a tuner like tom. Nobody knows these SVT engines better than tom & orange, so when they talk zetec shop zetec tuners should listen.

I would love an LSD for winter time because Michigan winter's can get pretty bad and winter tires do their job, I want a little more control and a little more power.

Torsen type LSDs do not perform well when one wheel experiences 100% slip. They are able to deal with (usually) a 5:1 situation -- if the grip on one side is 1/5 the other, the LSD can still put down torque to both wheels. However, if one wheel goes on ice or hard snow, that's still going to be 0 grip, and the torsen will act the same way as an open diff and spin that loose wheel.

You've got to be kidding me... the Honda K20A puts out well more than 200hp stock.

What is so out of this world about 200+ WHP on a Zetec motor? It's already been done a number of times in the UK. Our cars are already pretty maxed out as far as bolt-ons go, but do some head-work, custom cams, ITBs, up the revlimit and plenty of tuning, and you'll find lots of room for improvement. Do some looking around outside of FocusFanatics... this isn't the end-all be-all of Zetec information. That motor is used in a lot of cars.


Sorry if I sound annoyed, but you guys are stating information that you only read on these forums and are regurgitating it incorrectly. Bolt-ons will not get you there, but yes it's entirely possible.

Is this the same situation with Quaife, too? Are there other options?

A Quaife mechanical LSD is also a torsen-type LSD. I'm not aware of a traction system for 2WD cars that is specifically designed for snow as opposed to performance.

The really serious AWD systems use viscous LSDs and speed-sensitive (as opposed to torque sensitive) traction control measures. Here's a good starting article: http://www.autoworld.com/news/subaru..._all-wheel.htm

I never thought of it that way but nonetheless, it would still be cool have an lsd whether for summer time or winter time. I enjoy driving in the winter mostly because it has that WRC feel to it, and besides if you're in deep snow, I would imagine it would be better to have two tires spinning instead one, if you were backing up or climbing a hill. That's my opinion, but I fully understand your point Kimbo. Eventually, I'll end up buying an lsd sometime this year or next year.

Yup, I really like my focus in the winter i have the torsen diff and it feels much much better then my friends stock zx5 in the winter. I never got stuck once and i was driving through some pretty rough snow, plus drifting is much more controllable and fun, not that i do that on the streets hehe. For sure one of the best mods i got. I still have to take it to the track to see what it does there
