To get access to the spark plugs, how do you get the cap for each plug off the cam cover. Pull, twist or other? They're on pretty tight and I dont want to break anything by forcing it.
thx from the newb
PS My S2 is the first car I have owned where the spark plugs are not on the side of the motor.

It helps to twist the cap, then pull. Or twist and pull at the same time.

No such thing as a dumb question here man... other than, 550bhp out of a 944, how?

Well, if we assume the general premise that the more mechanical power you extract from an engine, the shorter the engine's running lifetime time, then theoretically this can be done, except that the engine would only last a fraction of a second. (Don't mind me. I'm just being a smart *** is all).

Actually, there is at least one NHRA inline-4 dragster around that is making like 1200 HP.

Personally, I think a 944 like that would be a super cool super car, but I don't think that the engine or drive train could be built to handle all that torque and live very long. It'd be way too expensive, I'm sure.

Nope - there's another dumb question that comes up from time to time:
I want to turbo my 944 n/a - how?

turbos are for wimps, you have to supercharge it: http://cgi.ebay.com/ebaymotors/Porsc...17457618QQrdZ1 , duh

While it's a valid question, the answer is typically it costs too much. I've thought about it, and I've come up with a list of things that I think would need to be address to get it done.

• Change Pistons from high compression to low conpression ones
• Upgrade the connecting rods, crank, and bearings to take the extra power
• Upgrade injectors, fuel pump and fuel pressure regulator
• Change engine management
• Change intake plumbing (and exhaust plumbing if it's a turbo) to include an intercooler
• Change the cooling system to handle greater heat
• Upgrade clutch to handle extra power
• Upgrade torque tube bearing to handle the extra load
• Upgrade transmission, harden first and second gears
• Install LSD in differential so as not to blow out ring and pinion with one wheel burn outs.
• Upgrade CV joints
• Upgrade wheel bearings
• Upgrade brakes
• Upgrade shocks, suspension mounts, anti-roll bars

Now, while you could take an NA 944, and swap all this out. It's possible, but not very economical when you could take the parts and labor money and apply it to a 951 and have almost all of it already in place. IMHO.

sorry. but i had too.
just cause a car gets an increase in power doesnt mean it needs all this other BS...

eohrnberger

OK, but if you have an S2 engine that's already 10.2:1 compression, and force induct more air, and therefore more fuel mixture, aren't you going to blow the head or the cylinders apart?

Or are you thinking a 8V 2.5L engine? Or is that a "depends on how high you want to run the boost"?

Techno Duck

Hehe, talk about off topic from the original question. I wonder if he got those plugs off...

eohrnberger

Yea, a bit off topic, but if Campeck is right, then he can save me just oodles of money!!!

Campeck

oodles of money sounds fun.
but yeah. on an S2 it might be wise to lower the compression. yes i was thinking 2.5L 8v and yes it still depends on how much boost. even the S2 might not mind a few psi of boost on stick internals.

Campeck

oh. and if you were already talking about an S2. then you already have all the stuff listed on your list. the S2 is just a different engine in a turbo shell. hooray!

I could destroy a 944 powertrain in good shape using stock power and enough stupidity. If you want to use the turbo to its full potential, and have a reliably fast car, I don't see how you can't pay attention to all of those things. The only way I could see the extra power being used without destroying things quickly is to select a gear on the highway and ease on the power.

Remember the racer's pyramid:
Good+ Cheap = Not fast
Cheap+ Fast = Not good , and...
Fast+ Good = Not cheap

i think the 86 951 had na cv joints...and btw they dont break catastrophically untill high hp levels. and if they were to break on an NA gone turbo..its prolly cause they were already in bad shape.
upgraded brake...just cause you can go faster doesnt mean you need massiv turbo brakes. the 924 carrera gt had single piston brakes ( i think)
transmission. seriously, it doesnt matter how little power or how much you have. the things suck..and will eventually break. but you can help that by not burning out and not power shifting into second. the ring and pinion shouldnt breaks from acceleration, just hard slams.
if your clutch is in good shape it shouldnt slip...but by trhen youll prolly already have a spring centered/upgraded clutch since so many are breaing nowadays.
