please anyone

engine and DME, flywheel, I think a different clutch, I don't know if the brakes and suspension were beefed up on the S2 over the S.

Well... Looks like it has most everything you need.. I say go for it. Though, with that extra power you may want to consider upgrading brakes too!

Blue S2

more hp! Smoother body lines. (turbo style) I believe a few mechanical bugs were worked out as well. Bigger brakes and slightly more tuned transmission i believe.

I think you have everything you need - that swap is very straightforward. I looked at it too but if you think about it, that's a LOT of money and work to get 20 horsepower. I'm holding out for a 968 engine.

joseph mitro

may only be 20 horsepower, but the extra 500cc of displacement makes a big difference in acceleration and low end grunt. sure you could wait for a 968 engine, but an S2 engine would be a significant gain over a S engine

not worth it sell the s and buy an s2,

there are a "lot" of small and big differences. also you will end up with a butchered s and a bastardised s2

again as was mentioned, your only going to get 20 horses more. you WILL need to upgrade the brakes and suspension.

not worth it

just my 2c's

also modifications can and will lower resell value in the long run

i suppose this belongs to the same category as changing N/A to Turbo. S2 is almost the same as Turbo. S is almost the same as N/A. Just sell your S and buy a S2.

well, here is the thing, his car is broken. it has been sense he got it. the S engine is (one of) the biggest piles of **** ever made in my opinion. he has had it in on 3 occasions, and every time a complete failure. that is why he is replacing the entire engine. S engines are way to much money, where as this S2 engine isn't that bad. resale value isn't an issue at all because it already has 3 different heads, all of which have failed within 1000 miles. no one will buy a lemon anyway. so, we are wanting to know if the S2 engine is for the most part a direct swap. Brakes and suspension isn't a huge issue, but if it does end up being a problem, that certainly something we can do something about.

adrian_jaye

let me just add a few more bits on,
(hoffman is also bang on)

the deal with upgrading is (anyway how I see it);

Changing a car very rearly is cost effective, and ends up with a car which is a hybrid and not one or the other.

In the UK, almost all chnages neeed to be passed to your insurer who may or may not load your premium, stateside this may be differnt.

Resale of a car which has been modified / converted etc, will be difficult, if not for a very ridiculos ammount of money.

HOWEVER, if you are doing any such projects just to see if it can be done, for your own pleasure, for meets etc. then bang on. It would be a very dull world if we never tried something new.

I didnt want to come over as a kill-joy, if you have the parts, money, no-how and can do the job SAFELY above all factors, and are aware of resale consequences. then kewl.

I think its easy to kill ppl's enthusiam for customising b saying stuff cant be done and we dont want to do that,

anyway my 2c's worth

peace

If you want to do it, do it for the fun of the project, not the performance gain, which won't be that much. To preserve the resale value of the car keep it stock.

I wouldn't worry about upgrading brakes - stock 944 brakes are way underrated. Their unsprung weight is lower than the 951 type items. And once you learn to use them to their limits, you'll be fine in any likely power output situation in a 944 series car. Main benefit I see to brake upgrades is if you can get ABS. And that's quite a project.

YMMV Al

Z-man

There was a write-up on this in Excellence a couple of years back: same thing you are trying to do: S to S2 conversion. IIRC, the biggest issue was how to get the S2 stock air intake shoe-horned into the area underneath the nose panel. It required some custom fabrication.

I also think you're better off NOT doing it: there are tons of components that need to be transplanted, and it may not work 100%.

My suggestion: keep the S, and if you get the S2 motor, look for a 944 S2 / Turbo shell. (I know of a 951 shell that is already prepped for racing: cage, seats...etc).

Just my $0.42,

I agree 110% with Z-man. The juice isn't worth the squeeze.

I'm also going to pull out my crystal ball and gamble in saying that motor will sell for at least $3500 or the reserve will not be reached.

Also, unless you know the person selling it, I wouldn't trust that everything has been done to the motor they claim is updated (belts rollers etc..) If the motor is out, why gamble?

If you agree, that will be another $500 - $700 or more in parts. Then the plug wires might be bad (not cheap) who knows what other small items are bad. You may be up to $5000 with the motor and parts before you even get it to fire. Then what?

Not worth it. Just an opinion.
