Lightbulb Turbo VS. S2

I am in the middle of the two cars. I LOVE the power numbers from the turbo and how easy it is to get big HP, but I also love the 16 valve engine of the S2. The S2 has most of the same items as a turbo so I was thinking of upgrading a S2 to get higher HP like just above the turbo, but how much $$ would I be looking at? How much would the car be? If it is going to cost TO much I might just get a turbo then. I know there are turbo projects out there for a S2 but I am not going to spend over $5,000 to get 80HP more. I just would like to have a S2 that can keep up or out run a stock turbo. I would think that it wouldn't be to hard because you already have 210 hp compared to the 220 of the turbo, plus you have another 1/2 of a liter to push you there. Another thing I don't quite get, why is the that the turbo is a full second faster to 60 then a S2 when the S2 has 10 less HP, but it has shorter gears?? Thanks.

Because the turbo has like 240 something torque vs about 215 for the S2 is why its quicker. But the shorter gears make up for some of it. I've driven stock turbos and an S2 is just about as fast...It doesn't feel like it though because the surge of boost makes the turbo feel faster..

Not gonna be able to get much more power in an S2 than it comes with. Intake, exaust, chip, they all help a little but it's not a real big gain. I think with a chip and a K&N filter you should be able to run with a stock turbo...unless they modify something in which case it's all over.

To get an S2 to turbo power specs will cost too much $$.

What types of applications will you use your car? Track? Autocross? Daily Driver? Weekend backroad stormer? Depending on what you'll be using it for will make a difference in what car is more suitable for you. (ex: for autocross, a 944S2, with it's low end torque is a better option, but for track usage, the turbo will pull better times, for the most part).

There's not a lot between a stock S2 -vs- stock 951 other than the lack of lag in the S2.

However, upgrades are sigificantly easier to obtain on the 951.

Isn't it also true that 0-60 #'s are thrown off because of the shorter gears, they give more acceleration but require a shift before 60, and the 951 can hit 60 in 2nd, reducing a shift.

I am going to be using it as a daily driver with a left foot. I guess the my main thing is, that I really like the 16 valve enging because it revs very nice, but I have never driven/riden in a 951 but I would think it wouldn't be AS smooth as a S2, can anyone tell me about this??

From what I have read the early turbos only have 216Hp not that big of a diff from the S2. Plus the S2 is cheaper to maintain ex.. clutch jobs can be 8hours less in labour. When a turbo is modded it seems to need a lot more TLC then the average bear. NOT A DAILY DRIVER, unless you have deep pockets. Don't get me wrong I LOVE TURBOS! I looked at a few before deciding on the S2, trust me it was a hard decision. Good luck on whatever you choose! You can't go wrong.

OK, so how hard is it to replace the clutch on a turbo compared to the S2?? How long are the turbos good for in the 951 about?? What all do you have to do when they do go out?? $$ and labor??

HUH? You got me Sid.

Mike the piping on the turbo I believe is what causes the extra labour when replacing the clutch. Ask one of the turbo gurus they will know. SKIP, DANNO, MARKSPORTS etc,,,, heeh

What would be the BEST intake to put on an S2 to get the most HP and the best sound??? I think I am going with an S2 for now and then do that. I am thinking about a chip too, where/who has a good one??? Thanks

The clutch on the turbo takes quite a bit longer from what I hear. The PO and his brother changed the clutch on my S2 in 5 hours, 20 mins. They said to do one on a turbo is at least 8 hours.

A K&N Cone in the front nose of the S2 makes for a killer sound..I love mine! And for a chip there's a guy on the e-mail lists I think. Steve R is his name. I probably still have his e-mail address if you can't find it when you're ready to buy one.

i think that usa has has lower numbers because of lower compression, why they did this was maybe to guard against inferior fuel (and lower octane)...?

i've read this (bmw enthusiasts guide) on the early 80s bmw 320i.. even though they (bmw) sold a lot of them, they were underpowered compared to the 2002.

how about an image of a 951...?

and with different wheels:
