Firewall brace is in!
#1

I decided to work off some of the effects of the Thanksgiving gluttony by installing my recently-arrived firewall brace, and it went very smoothly. My engine is out of the car, which may have helped with the installation process a little, but not a whole lot, I don't believe (so there's no need for Flash to add "Remove engine" as the first step of the installation process on future kits <img src="/forum/images/smilies/968/tongue.png" class="smilie" alt="" /> ).



Since my front struts are also out of the car at the moment, my goal was to permanently attach the firewall bracket to the clutch master cylinder, with the strut brace bracket temporarily held in place by four bolts and nuts to confirm the fitment of the tower bracket to the firewall bracket and strut tower bracket. I'll tighten the rest of the nuts and bolts down when I install my new Moton Clubsports, which probably won't be until after I put the engine back in. It is a tight squeeze in there, but I found a method that worked very well for me:



1. Place the clutch master cylinder's left-most nut into a 13 mm socket.

2. Attach the socket to a universal joint, which is attached to a 3" extension, which is attached to a 12" extension.

3. Attach a telescoping magnet to the socket, and use the magnet to keep the socket in a horizontal position while maneuvering the socket toward the clutch master cylinder's stud.



I ended up attaching the firewall bracket to the clutch master cylinder stud using this method (without the loctite), then hand tightening the tower bracket to the firewall bracket, and to the strut tower bracket to confirm the fit of everything. Then I removed just the clutch master cylinder nut, applied the loctite, and used this method to maneuver underneath the fully assembled parts described above, and torqued the nut down.



This is a very high quality product, and I would encourage everybody to add it to your list of things to do for you 968. It isn't expensive, so it's very cheap insurance against the firewall integrity problems that are so common in these cars. It just feels solid as a rock. Five stars!

Thanks, Rob. It's slowly coming together. I'm having the crank checked for trueness, and then having the entire rotating assembly balanced, and having the deck height checked and adjusted as needed, at a local machine shop, as well as having the spindles modified to accommodate the thicker ball joint pins that are part of the heavy duty control arms I recently bought. Once this is all done, I start putting it all back together, so I'm hoping to be done by late December or early January.

One of my friends is Robert Turner and I recently spoke with him at the local Cars and Coffee in Dallas. He used to race 968's and said he loved them but had problems with the oil pick-up tube breaking as a result of hard cornering. Have you ever heard of that issue? Sounds like it is related to the shifting of the oil in the pan. I would think Porsche would have baffles in the pan.

Yes, oil pick-up tube breakage is a fairly common problem, but it isn't caused by hard cornering - it's caused by vibrations weakening it over the years. Mine is fine, but I'm having the machine shop weld a support brace onto it in the location where they tend to break. Also, I'm planning to order a weld-in oil pan baffle from Lindsey Racing:

My understanding is that this helps keep oil collected in the area of the pan when the pick-up tube sucks it up during fast sweepers (I think this is what Robert was actually referring to when he mentioned oil starvation problems during hard cornering). I think this sort of starvation is more of an issue with earlier 944's, but the extra baffle isn't expensive, so I figure it's cheap insurance.

Hey cloud, didn't get a change to take any pics of the installation, did you?

No, but I could snap a few. I'll try to remember to do it tomorrow. If I forget, feel free to send me a reminder PM.

it has been gratifying at how well this item has been received. i only wish i hadn't second guessed myself on the first version, and had gone ahead with the second version in the first place.

My firewall & strut tower braces go in today! I was waiting for a weekend with good weather and no "honey do" list. It started to look like in would be baseball season before I could get to it, so I'm having my P mechanic do it today. O.K., so I wimped out!

With firewall brace v.2 installed, Flash and I have confirmed that I have absolutely no movement at the firewall. The flex I'm getting at the pedals is from the pivot assembly under the dash. I haven't looked under there yet to see what's what. Flash, could this be a potential weak point that could use a sturdier D1R solution?

not likely. the pedal is plastic. i would be worried about it breaking. somebody here recently had that happen.

A bit OT, but not too far.



Andy are you chomping to get to the track? With all the work you've put into this project it will feel like a new car I bet. I'm looking forward to hearing about your laps in the new girl.

Flash I don't think my pedal arms are flexing (well maybe some, as they are plastic), I think it's the assembly that holds them. Coming to a stop with my right foot on the brake, as I push the clutch in to shift to neutral I can feel the brake pedal moving, like the part that holds the pedal pivot bolt is flexing or twisting. This is why I initially thought it was my firewall that was flexing. I'm sure once I get my 2500 lb. pressure plate installed this movement will be minimized.

Yes, I'm definitely chomping at the bit, but I continue to run into delays as I keep coming up with "while you've got it apart" things to do. I've got the block and all rotating parts back at the machine shop to have the deck height checked, to have all rotating assemblies balanced, and to have the spindles drilled to accomodate the larger ball joint pins in the new Racers Edge A-Arms. Basically, I want the machine shop to give everything a thorough once-over to make sure everything is right before I put the engine back together. Good thing, too, because they found a small problem - the clearance between the rod big ends in my new Pauter rods and the crank journal is out of spec. Plus, to be honest, I'm feeling guilty and anxious over how much money this is costing, so I may have to draw it out longer than I'd like. I think I've forgotten how to drive a stick shift, let alone how to turn blistering times around a track!

Just don't climb into the newly-finished race tub and stuff it into a wall! <img src="/forum/images/smilies/968/ninja.gif" class="smilie" alt="" />

Ooh!! Don't even say that! Fortunately, none of the tracks near me have any walls, and they have plenty of run-off (which I've taken good advantage of on a few occasions <img src="/forum/images/smilies/968/wink.png" class="smilie" alt="" /> ), so I'm OK in that department.

OK, as promised, here are a couple of pictures of my installed firewall brace. Unfortunately, it's very hard to see much of anything because of all the other stuff around the brace, and having the engine out of the car unfortunately doesn't help in this regard, because there's still a lot of stuff on the firewall. But here they are:

Good luck with the install. Using a telescoping magnet against the socket to keep it in as near a horizontal position while maneuvering it toward the clutch master cylinder stud worked very well for me, as I said.
