993 HEs are larger tubed than the SSIs HEs commonly used on back dating the 2.7, 3.0 and 3.2s so that they can use a dual in banana muffler. There is a HP gain for the 2.7 and 3.0....not much for the 3.2.

It's a bit hard to plumb in a cat but it CAN be done. I have posted pics of my custom set up a few times....

The 993 HEs need to have one side exhaust port/head flanges re-oriented so that they fit. Ingo has access to a jig to have them done. The prices on the 993 HEs have gone up of late.....so look around.

That is what I wanted to know. Just had not heard of it being done before. Thanks. Hijack officially over...:)

How to buy your 911 twice, one box at a time...


I love this thread title.

I will confess to be one of the ‘temptors’.

I spent my professional career and more recently on Pelican ‘helping’
Porsche owners spend their hard earned money making their 911s better.
Ask anyone in Denver and more.


The good news is I think I helped wisely.
Ask anyone in Denver and more.

I hope to continue.
My goal (as always) is to use my lame advice to improve 911s correctly and at least cost.
There are many more I hope to encourage.

Porsche built (builds) great cars.
They can be better given 20-30-40 and even 50-60 years of hindsight.

Best,
Grady

great read

JeremyD 12-19-2007 07:03 PM

Sounds like you are headed in the right direction - from my research = you have a couple added options with exhaust. B & B - they will make you 1 3/4" 964 headers with 3.2 heater boxes (But only a custom or B & B Muffler - and Steve Weiner has a deal with GHL to do essentially the same thing (the good part is you can use stock spacing muffler - not just GHL or B & B)

this is a great thread...count me in...to learn (sorry, I cannot add much other than my support as I am a tech novice.)

schnellmann 12-19-2007 07:18 PM

Thanks for the encouragement and feedback, guys. I've been so slammed at work lately that I simply have not had enough time to write up my progress even though I've had everything I need to finish for a couple weeks.

But I have made some progress and I have been taking pics along the way. :D

I'm off work all next week so I am optomistic that I'll be able to get it all buttoned up and possibly even running in that time frame.

I have a couple more good "I really wish I'd known..." items all queued up. I am going to try to post progress daily during the remainder of the build phase.

Stay tuned... and as The Governator says... "I'll be back."

Part III - Tool Time with Troy
 
[I had a bit of free time tonight, so I wrote another installment. And it's actually Part IV. Here goes...]

Before I resume with the really important and exiting build-up episodes, I’d like to talk about tools for just a bit.

I’m not a mechanic, but I have a lot of tools. You pretty much have to in order to undertake this kind of project. My wife says there’s not one thing at Sears or HF I don’t already own. Not quite. I have 3 or 4 of some things they sell there. :)

Now I suppose I consider myself of an something of advanced tool user. I’ve been using them since I was a teenager. After a few successful projects, you understand where things are how things actually work. Though once you get the hang of using your tools like you’re supposed to, the relationship with your tools that was once so thrilling and fulfilling can start to become dull… even perfunctory.

Every now and then you need to spice things up a bit. So when the urge strikes me I like to try using tools in unorthodox and/or in ways their makers never intended. For example...

Lesson #1: You’ll always forget to buy a flywheel lock. Or if you managed to get one for a previous project, you’ll use it so infrequently that you’ll forget where you put it. If you’re anything like me – which means you’re irrational enough to sink hundreds of hours and 10s of thousands into a car like this – the thought of plunking down 20 clams for silly piece of toothed metal with a couple holes drilled in it is totally and completely wrong, immoral and possibly even unpatriotic.

Bottom Line: You totally don’t need it. Sure, you could do as Wayne suggests in the rebuild book and go to the hardware store, buy a piece of flat stock for 3 bucks, cut it down and drill holes in it. But the hardware store is like 5 minutes away. And that would also mean I’d have to dig the drill out of the drawer all the way across the room. Why not just walk up to your tool cabinet and see what you already have? So that’s what I did, here’s what I found and this is how I used it:

http://forums.pelicanparts.com/uploa...1198127229.jpg

1/2” on one end, 9/16” on the other. M6 allen head bolt in the flywheel. Works like a champ. ;)

Now as you can obviously see, I truly believe in using the right tool for the job, which is why I love my Dremel so much. No matter what the job is, with a bit of fiddling and a HF mondo rotary tool accessory box, it’s always the right tool.

Have Dremel, will travel.

Seriously… there is no mechanical conundrum this thing can't solve for you. If it’s too big, grind it down. If it’s too long, use a cutoff wheel. If it’s rough, polish it. If it’s too heavy, put some holes in it. ;)

But the real beauty of the Dremel is that it’s the tool you can use to make the right tool. As you’ll see in a later episode, I bought a set of 98mm JE pistons for my build and those that have JEs probably already know where I am going here.

Lesson #2: While pretty much everything about JE’s pistons is really nice, the circlips used to keep the wrist pins centered were obviously made by the devil. They are twice as thick as the stock ones and 100 times as springy. There seems to be two ways to approach getting those things into the pin bore. The first way requires 1 hour each, absolutely no children within earshot, a large box of band-aids and a six-pack (at least).

Bottom Line: There is another, much easier way. While it does require a trip to the hardware store, that pain is more than offset by the pleasure of using the Dremel to fabricate a new tool. Oh yeah...

And, like the flywheel lock, you could buy the Porsche tool. I have no idea what they sell it for, but as you’ll see in a moment, it’s too much.

What you need to do is find yourself a 7/8 ID bronze bushing. Grab the Dremel like you mean it, slap a cutoff wheel on there, make revolutions for warp speed and trim out a section like so:

http://forums.pelicanparts.com/uploa...1198127312.jpg

Note: I wish I could take credit for this, but I saw it on another post a while back. What I never saw anyone post, though, was the technique I used for actually inserting the circlip into the bore. Before attempting, put on your safety glasses. The ends of the clips are sharp and when these things pop out, they really pop. I kid you not – on one of my first attempts the clip flew out and actually stuck in the ceiling.

OK, so the process is as follows - first, you’ll have to go to the trusty tool cabinet with your newly crafted masterpiece in hand and find yourself a socket with an OD that closely matches the ID of the bushing. While you’re at it, get a small hammer too. A plastic faced one works nicely.

Next, go back to the workbench, place the socket and hammer within reach and insert the clip with your thumb. The split end needs to be pointing upward. It takes some pressure - no need to be gentle:

Now we arrive at the "finesse" part. Gently rotate the clip about 20 degrees from vertical, so the split is more or less centered in the notch of the bushing:

http://forums.pelicanparts.com/uploa...1198127531.jpg

This is the part where the clip is most likely to go supersonic, so approach the piston slowly with the bushing in hand. The cutout and the split end of the clip should be topside, as shown. Now carefully insert the clip in the pin bore, setting the clip ends into the ring recess. Grab that socket and hammer you just put down a minute ago and insert the socket into the bushing until it butts up against the clip.

http://forums.pelicanparts.com/uploa...1198127618.jpg

Give the end of the socket a nice, firm tap:

http://forums.pelicanparts.com/uploa...1198127644.jpg

Voilà!

Total time to insert each clip: 45 seconds. Number of profane words used: 0. Total cost: $1.26. Making your own tool that actually works? Priceless.

To be continued…

Troy -

That is SO friggin clever! Thanks for the great tip. Those suckers are a PITA.

Great write up and attitude for tackling this stuff.

subscribed; thanks, Troy!

Thanks guys. More to come... :D

Dennis Kalma 12-20-2007 10:21 AM

Troy...you are my hero. Those clips had me all a'twitter as I generally am the guy who fires them across the garage, have them get lost in the clutter, with perhaps a chance of finding them only if I embed them in my fingertip whilst groping around.

You have saved me at least 6 puncture wounds, half a litre of blood and ensured my salvation by reducing the amount I take the Lord's name in vain.....
