Turbo tierods on early car

beamonk · 01-29-2006, 03:28 PM

How difficult is it to put turbo tierods on a early car circa 1967? Any special modifications?

Thanks

Anyone?

I put some on my car ('70) about 1.5 years ago. It's not that hard from a technical stand point, actually fairly easy. The difficult part is getting the old ones unscrewed from the steering rack. Spray some PB blaster (which I hadn't done) on there the day before (or a couple of times) and it should be easier.

The problem is the rack is up in a kind of inverted valley and it's hard to get a wrench in there to turn the tie rod end. I just had to make TONS of tiny turns repositioning the wrench each time.

Thanks for the reply, this is for a 67S which came with a different steering rack.

John, the issue is that the Turbo Tie Rods are shorter, and as a result, only one or two threads engage. I have not heard of anyone fixing this issue. I have heard that Will at CSP recommends that SWB guys stick with the original tie rods for this reason.

I suppose one could come up with a new threaded piece but you would be a test pilot as far as I know. I'll check with the usual suspects and report back, this is a mod I could use too.

John, are you saying the rack is narrower on SWB cars?

Zeke · 01-29-2006, 08:14 PM

How about an offset bump steer kit? Or, since I've seen many times where people say it's OK to heat and bend the sterring arm down, why can't you bend it in some? Too much change to the Ackerman?

It seems it would be easier to replace with a later rack, but the steering assembly might ave a different offset.

John,
I think you would really need to upgrade to a complete later 911 front suspension to really be able to use the turbo tie rods. I've been looking at bolt-on upgrades to put together a plan for the suspension for my car and that's the conclusion I've reached.

rexav8r · 01-30-2006, 05:39 AM

I think I've got the same understanding as Chuck, that you guys are saying the steering rack in narrower.

I had forgotten that.

Seems that a longer threaded tie rod end would be fairly easy to fabricate for the right guy. --Chuck ??

It would also appear from what you guys are saying that it would really be the simplest solution too. Other than going with OE tie rods.

Do you guys think there's a market for these? I've got a good buddy back here that's been fabricating a good number of Porsche parts, especially early not-too-common parts. He would probably be able to make something... I'll e-mail him this thread and see what he says ?

I am in the middle of doing a suspension refresh w/ one of chucks/elephant racing kits in my 68 912. It came w/ the turbo tie rods and i had assumed this would work. I will hold off on that part until I hear of a solution. I just heard of this problem this weekend while reading a thread on the 912bbs thread. Chuck if you need me to take some measurements or whatever, let me know since i have the 68 and the turbo tie rods.

I think that this different rack is more applicable to 65-67 cars. I think the 68's received the more modern rack. I am not the expert here so hopefully someone else will chime in.

ronw · 01-30-2006, 07:48 AM

ok, i thought it had to do w/ the fact that the 68 had a swb. 68 is that funky year that i dont know wheither things are the same as the 65-67 or 69-73.

thanks

In the FWIW department, I had my brakes rebuilt/lines replaced a couple years ago. My wrench (the dealership, and he's been very good to me) told me the prices for stainless lines and rubber lines and recommended the stainless for the slight increase in cost. Then told me the tie rods should be replaced and that he'd use the turbo tie rods. Don't have the parts numbers handy, but apparently it can be done on a '68.

rexav8r · 01-30-2006, 07:58 PM

Well, I wasn't able to find out anything other than my buddy is bussier than He!! right now !! Sorry.

Still seems that a tie rod end that's been extended with more threads showing, should be a pretty easy piece to fabricate??? (but I'm NO fabricator!!)

swb has more to do with the rear end of the car I believe than the tie rod/steering/front suspension. Though the components changed with the model years.

FWIW - I have the turbo tie rods in my 68.

Chuck Moreland · 01-30-2006, 09:49 PM

Bob, do you have the original rack? And how much thread engagement into the rack and the tie rod end?

bob tilton · bob tilton's Garage

Sorry Chuck I didn't refer back to this post until I just now did a search. The topic of SWB cars and turbo tie rods has I guess never been answered...at least for me and the funky 68 model year.
The topic is being discussed on the 912bbs...again. I can't recall the number of threads inserted into the rack as my dad and I upgraded my entire susp several years ago. Since it was done by non-porsche experts I could be wrong in assuming they would work and were properly threaded. I do not know if the 68 has a different steering rack. I need to get under the car this weekend.
What I do know is that we did all the work and the car was dropped of at Deutche Motor Sports and was lowered, aligned and cornerbalanced. Seems to me they would have said something in re: to the TTR in my 68. I do remember the mechanic giving me the hard stare with a slight smile after looking over our work and saying "you left a few of the bolts a little looser than I like". So I assumed he checked over everything...I don't know.

Hi

I have a '67 (not a US one - I do live in Africa after all) and it has Turbo tie rods in (installed Pelican's kit) - I have not noticed any issues regarding not enough threads, but I will be sure to check very soon.

What appears to me is if I look on pelican parts - there is only one steering rack available 65 - 89.

http://www.pelicanparts.com/catalog/shopcart/911E/POR_911E_SUSstr_pg1.htm#item4

I asked my parts guy at a local Porsche dealer if there is a difference in the part numbers

65 - 67 - there is one number and it is superceded from 68 - on with 91434701006 - to do an update, all that is needed is to replace 2 support washers and 2 bushes - which across the telephone appear to be simple spacers between the rack and the tie rod.

Pehaops someone with better access to a catalogue could post the part numbers and pictures of the update parts.

Guy

Hi.. I have a 73' coupe and replaced the tie rod ends along time ago. You will notice/feel the difference. Now I have installed a bump steer kit.
Everyone has bump steer issues when you lower the car. So the solution is bypass the turbo ends and go right to the bump steer kit.A side note I replace my steering rack with a 86' carrera rack. Its suppose to be a shorter turning from stop to stop.I got it from **********.com it was a rebuild and only $280.00 plus a refundable core charge. The people at Porsche in SLC Utah get around $800.00 for the same rack.
