Whats the Most Durable Guibo for Track Use?

[djjerme]

because racecar! I almost had my weekend ruined by busting one, luckily another spare...actually 2...its easy to make the same mistake twice

No kidding, went through two lower radiator hose last weekend at ORP before I realized I busted a motor mount. Luckily, it was a double header race, and I was able to use a friends PRO3 to finish the second race..

really? like you're going to pull over on the side of the road and swap it out? lol :p

I usually carry enough tools with me to do so lol.

like other have said, never had any issues except when something was installed incorrectly. That being said, I always carry a spare with me.

Stamar, you want to see some guibo problems? Check out the Alfa GTV6 and Milano. You must be doing something wrong if you are having trouble with yours.

Comparing the photo in the original post to the photo below from a Pelican Parts Tech article, it appears that the guibo is installed in the same orientation, no?

Nope. :loco:

Looking at it again, and again, and once more, they are NOT in the same orientation. This one is backwards.

Comparing the photo in the original post to the photo below from a Pelican Parts Tech article, it appears that the guibo is installed in the same orientation, no?

The only difference I can see, other than the buggered guibo, is the orientation of the bolts.

For proper installation the bolts should run through in the direction of the arrows moulded into the sides of the rubber guibo. The red arrow in the photo points at the triangular arrowhead stamped into the rubber.

First bolt the guibo to the driveshaft flange. Then bolt the driveshaft with guibo already attached up to the transmission flange.



This way the guibo will sit, as shown, in the proper orientation with the thicker portions taking the load under acceleration.

There are metal sleeves bonded into the rubber of the guibo through which the bolts sit. Those, obviously, prevent the rubber from squishing as the bolts are tightened.

Here's where I suspect the problem is. You must hold the bolt head from turning while tightening only the nut. That way you won't twist the metal sleeve in the rubber, possibly tearing it from the rubber.

Another reason the proper bolt direction is important is that, with long exposure to salty climates, the bolts will eventually seize solid into the metal sleeves, potentially making it impossible to withdraw the bolts from the guibo. If the bolts run as shown, you only need to remove the nuts to remove the guibo with bolts still embedded. Then install a new guibo with new bolts.

If you install the bolts the other way around, opposite to what's shown in the photo above, that would have the bolt running first through the metal flange of the driveshaft/transmission and then seized solid into the metal sleeves embedded in the guibo making it difficult to remove the guibo later.

Really, though, I don't know why I'm bothering to respond to a typical stamar post. We have determined that E30 guibos are undersized on the basis of one that was probably an incorrectly installed Chinese knockoff, even though the replacement has been working fine for years. Oh yes, and furious googling.

This.

Clutch kicks kill my guibo's(and engine mounts and trans mounts) also I'm pretty sure I need my Drive shaft rebuilt as well.

[Wanganstyle]

it's a lot harder to search for all the people who have perfectly functioning guibos, because they aren't posting about it.

++ agreed.

took me a season and half of events (dozen + track days) +3 months of S54 engine swap street time to wear out the e36M OEM guibo on my e36 (running slick tires and high locking diff). Even then it was just cording; not exploded or destroyed.

i did that a few too many times and realized i got nowhere. now he's on my block list.

[nrubenstein]

My guibo shredded.

It could have been put in wrong I didnt do it. It could have been chinese. I cant tell you. I just knew it blew up and fast and knocked shit around.

The one I put in, is a febi guibo and its still there.

If e30 guibos are great nando....

why do e30 m3s have a bigger yoke and guibo size then, using the guibo and yoke size from the m30 5 series?

or better yet, why does the 6 cylinder e30 have the same size guibo and yoke as a 4 cylinder e30.

Yet a 6 cylinder e36 has a bigger yoke and guibo than a 4 cylinder e36 ( which also is the same size as a six cylinde e30)

why is the guibo on the six cylinder e30 smaller than the one on the 4 cylinder volvo 260 where as the one on the volvo 260 is the same as the one on the m3 and the e36 m50?

Its because its weak ass small guibo!!! LOL bury your head in the sand lol. Brilliant german scientists worked for years on a chalkboard and decided the small one was enough. I hear you.

most car owners other than bmw owners dont even know that guibos wear out.


you cannot even go to google and type bmw e30 common problems

http://e30world.com/Maintenance/BMW-E30-common-problems

without getting the word guibo for the first 50 entries.

Porsches have guibos too, but most porsche owners dont even know what they are. something you replace with the driveshaft breaks.

Go to google and type "guibo problems" and find how often the internet is talking about bmws. Its common knowledge... If you even try to type porsche guibo problems, most of the results that come up in google are bmw owners saying " my porsche never did this" or porsche owners saying " my bmw used to do this"

Also, 911s tend not to blow out guibos because they are rear engined. So the only time you have a guibo to blow is if it's AWD, and even then, it doesn't have a lot of torque going through it.

6 Cylinder E36s make more power and torque, everywhere.

I've never had a problem with a properly installed guibo, and my car has 3 of them..

also, if you search for "problems", you're going to find them. duh.
