Jeff - I called JE and they recommended NOT to excercise the rings first. Like golf it's all technique.

As far as power - I drove my car today - it's a beautiful day here - and I don't think you'll be disappointed. It's running like a scalded cat.

0-60 is in a flash. And you should be making more power than mine with a higher compression and the ITB's...

Jeff,
I did a good one a couple of weeks ago. I was working on the wiring under the hood when I bent over into the trunk I hit my head on the corner of the hood and split my head open. My girlfriend fixxed me up with some Crazy glue and a bandaid. Crazy glue is an old Sushi chef trick. Keep at it man!

Yeah, I had heard the same thing, but was told by another builder who uses JE products regularly that if done "carefully" (not to the point of actually deforming the clip) it helps slightly. And it did help slightly. The first few I got on without "exercising" (that's the word I was looking for) and it was a PITA. The others I tried the trick and it was still a PITA but just slightly less. My fingers were sore though!

Sorry to see that Jeff. I gave myself a couple scratches installing the clips but nothing that bad. Anyways I took an old flatblade screwdriver that I had an extra of and cut a notch in it large enough to grab if you will the clip. I found the while still on the bench working the clip into the side of the piston in the grooves softens them enough to make installing on the motor much easier. Also if you cut the groove tight enough you can grab onto the clip by twisting the screwdriver. Then I stuck a punch into the pin so things dont go flying, work the clip in as best you can with the notched screwdriver and then with another screwdriver, need nose or your fingers you can slide the last section inside the pin bore and then snap it home.

Hope things get easier from here on in for you. FWIW I can give you a couple tips on the jenveys when you get to that point and also some more pictures of the throttle linkage plate that I made and how I modified the bellcrank arm on the trans. Get that top end together!

Cheers, Ryder

Ryder, thanks , I will be picking your brain I am sure on the ITB's, they should be here soon.

I actually notched a screw driver........ and then it notched me. Maybe it was not too happy with me! I had put a couple of clips in last week when I was checking deck height and thought "well, that was not too bad." Not sure what went wrong this time......

Too tired I guess....

Cheers

I did the same thing - although stuck the screwdriver into the fleshy, palm - man those notched scredrivers get sharp! I bled a little on the engine - figured it was partial sacrifice to the Porsche gods...

Now when people ask me if I have blood and sweat in my car I can tell them that they have no idea...

Jeff Alton · 05-17-2006, 12:40 PM

I think we need to start a brotherhood of those of us that have given blood to build motors!! Time to get Ryder to contribute I think.......

Cheers

Jeff,

That sucks! I was putting mine on this last weekend and just about did the same thing. Hadn't gone very far and the fingers had had enough. I ended up making a tool to insert them. I will get a picture of it. It make the on engine insertion easy and takes a little practice on the bench but is definately safer.

Jeff Alton · 05-17-2006, 10:21 PM

Lets see some pics, Mike J made on but it only worked on his 993....

Cheers

88-diamondblue · 05-17-2006, 10:48 PM

Jeff,

I will post pictures early tomorrow night.

JeremyD · JeremyD's Garage

Mike Burns at JB Racing in Florida makes a tool too -

Jeff Alton · 05-18-2006, 08:15 AM

150 or so bucks though! I may end up having to get one. I avoiding another 6hr trip to the ER has to be worth something!! This is my first go with JE pistons, better find a good way to get these in or it will be my last go.....

Cheers

after wrestling with the ones in my car - if I go JE again - that's the route I will go. (or have someone else do it)

88-diamondblue · 05-18-2006, 07:19 PM

Jeff,

This is the tool that I made to insert the JE wrist pin clips. It works great for the pistons on the engine. On the bench you need to be careful not to push the clip past the groove. I did and had couldn't get one wrist pin all the way in. Had to take it to my engine guy to smooth out. If the wrist pin is in this won't happen. I just put the wrist pin into the piston and then push the clip in. The clip is put in at an angle with the ends sticking out. They will contact the groove and you use the plunger to push the clip on. Took just seconds to get the clips in and it would be hard for them to fly away. If the part was machined it would work even better. Any questions let me know.

Jeff Alton · 05-18-2006, 07:24 PM

That looks just like the one that Mike made up, that I have here. The difference is in the wall thickness, which we need to change. Thanks so much for the pics! You are the man!

Mike J, lets make a few of these.

Man, my hand hurts.....

Cheers

Mike Juzenas · 05-18-2006, 07:39 PM

No problem but I hope you are not in a rush ; I am going down to Seattle this weekend and won't be back until Sunday night. We can fire up the lathe on Monday (if I get clearance from the spousal unit) and fabricate one up. What are your shifts like these days?

A few questions about the tool:

1 - The flattened side is to clear the skirt of the piston? It looks like its tapered?

2 - Can you post the measurements of the tool, i.e. outside and inside diameters of both pieces?

Thanks very much for the pictures, that helps quite a bit.

Jeff, I have some bronze shafts left over from the last tool I made ; can we start with the tool I made or do we have to start from scratch?

Cheers,

Mike

Jeff Alton · 07:46 PM

I think we may be able to use the one you made, but with the measurements, I can source the raw stock. I am off this weekend but have my son in tow so monday is probably out, but we can work something out next week I am sure.

thanks mike (both of you!)

88-diamondblue · 05-18-2006, 08:37 PM

I will get the measurements this weekend. It needs some tweeking but will give a base for making it. This was done with just a grinder and drill press so the measurements will only be close. I think I have a clip that I can put in it and get a picture of how it fit. The taper on it was due to everything being done by hand, grind and see if it fits

88-diamondblue · 05-22-2006, 09:03 PM

I got the measurements tonight and will get them posted tomorrow. Just got too late tonight and a few issues with the rebuild.

I found that by wrapping my thumb well with duct tape, I could get enough pressure without sever pain combines with the notched screwdriver technique to get the clips in. Took an average of 5 tries per clip, but it works.
