Bob S and I have already gone through this before a while ago, but coming from Hondas, I prefer working on my 944. With one exception, the electrical system (Bob and I agree on this).

Honda drives their water pumps off of the timing belt aswell, but I don't remember it's position relative to the radiator.

 

Dodge Neons and I think Ford Escorts??? run the WP off the timing belt too. It's not a bad design actually and makes for a more compact layout. On a 944 if the WP pulley wasn't there, you'd still need a idler pulley so the belt wraps around the cam gear sufficiently.

 

If you think that the power to weight ratio is high on a type R consider a s2000 has a NA 2.0 L that puts out 240 hp. That is 120 hp per liter. Another screamer of a motor is the motor in the Hyabusa it puts out hp in the neighborhood of 175 out of a 1.3 L that is a mind blowing 134.6 hp per liter. The new E46 M3 has high HP to displacement ratio as well although I don't know the exact numbers for it.

The thing that gets me is how efficient can these engines get? What are we supposed to expect out of performance cars in 10 years time.

Are we going to see engines with HP/displacemnt ratios close to what F1 cars can do? I know that isn't practical but can you imagine. A half liter engine with 200 HP.

We are living in the good times.

These engines aren't badly designed. They are designed in the typical German style. They are a treat to work on IF your toolbox is bulging with Special Tools No's 0 - infinity, nothing seizes and you do things the ONE way they are meant to be done.

The Tiger tank required the removal of FIVE wheels to get at one of the inner ones. Be grateful you aren't being shot at.

The current state of the art n/a four cylinder is the S2000 engine - 240bhp out of 2 litres @ up to 9000 rpm. I don't think that is going to be fun for amateurs.

 

Jax951,

I agree with your C-ring problem. Are you working from under or from the top?

I did mine from the top, and it was a bear. Next time, I will probably make more room for myself by removing the fans.

Hope you've already got the t-stat in and no longer need to read this thread.

 

"C-ring" I thought that this was a Porsche site.

 

Good thread, Gang...

It should be used as an example of how a subject can be discussed, even with different opinions and not stoop to name calling and rancor.

Go to the Cayenne forum, key in on the thread Cayenne is awesome....no other comment required...

Maybe all cars are becoming just a bit too complex nowadays...Could it be that the modern engineering schools teach a course in "Screw the owner...full speed ahead!!"?

Cheers and thanks

Bob S.

 

Just to let you know, I gave up trying to get that seal out. I decided I would pull out the water pump and then remove the seal. I pulled out the intake with some plumbing, only to find out that the waterpump is about a foot long and is driven by the timing belt. To get to it I'd have to remove the cam cover, timing belt and balance belt. If I'm going to take it all off, I might as well replace it. If I'm going to replace the belts, I might as well replace the rollers and front seals. As far as I know, the water pump is original, so I might as well replace it too. I've got the distributor cap off, so I might as well replace it and the rotor, and while I'm doing that I might as well replace the spark plug wires. Once I'm all done with that, I'll still have my pinging problems, so I might as well replace my FPR with an AFPR (I've already changed everything else in the fuel system apart from the fuel pump - hell that might even be next).

I ordered it all - approx $700.

I've had the car since March. By this weekend I will have put the following into it (all myself):

New plugs
New plug wires
New dist. cap and rotor
New fuel filter
Serviced injectors
Serviced ISV
New braided fuel lines
New timing belt
New balance belt
New rollers
New water pump (not rebuilt)
New intake manifold gaskets
New front engine seals
New Lindsey Racing AFPR
New Forge BOV
New Turbo Water pump relay
Many New vacuum lines
Many new Water Hoses.

Whew. I'd say that's quite an accomplishment in 3 months of ownership.

My estimate is $1300 on top of what I paid.

I guess I'll see what nightmares I come up against this weekend.

I did mine without removing the cam cover as you call it, cam tower in actuallity. But I have an NA (there is a lot more room). Also, if you can get the fans off the front it is much easier. It is easy to get the fans off the front in the NA, but in the Turbo the oil cooler line gets in the way (I don't know what is envolved to circumvent it).

 

Sorry - when I said cam cover, I meant the cover on the end of the cam tower. It covers the "sprocket" (I forget the actual name) that turns the cam.

 

Would someone mind filling me in on the rebuilt waterpump deal ?? Seems that people are not reccommending going with rebuilt unit -any particular reason why, since i'm about to replace mine ?

 

Many people have had them fail within 10,000 miles of replacing them.

 

Jax951-

No problem. I just didn't want you to go to all that extra work for no gain (I have had my cam tower off).

The bit that covers the cam pulley comes off in 2 minutes with 3 screws.

 

When you say fail, what do you mean -bearing failure/seizing, leaking ?

 

Yeah I've heard that rebuilt ones are not reliable, which is why I chose to go with a new one. I bought my latest batch of stuff from Paragon. Rebuilt was I think $95, and new was $187. I resisted all temptation to save $100, and paid the $187.
