anyone have pics of the engine mount bar for a 3.0, 3.2 and 3.6?

Thanks again, great information!

I am feeling more and more confidant that I am on the right track.

Why does the cross bar need to be bent? Is it because the 993 case w/ 3.2 mount console pushes the center of the bar back more than a 3.2 case would?

Crossbar was bent so that the G-50 would fit without cutting the torsion tube.

Bill,
The 993 crossbrace was bent when I installed the 993 3.6 with a 915 into my 86’ coupe in 2004 as well. It’s just a different chassis thing as far as I understand. I am not sure of the dimension differences between the 3.2 and 3.6. But my intuition says the 3.6 could be a bit longer due to the size of the bore and it’s more modern chain ramp architecture etc…

Dannobee,
I have a thread showing that the torsion tube still needs to be cut up and pounded in to fit a SBH G-50 into a G body. And yes, the crossbrace still needs to be bent forward a bit for all that to work.

I hope this clears up some questions.

Regards,
Steve

Nope. The 3.2 and 3.6 engines are the same size.

That's part of what's driving me nuts, it was all done back in the mid 90s and I do vaguely recall that the 964 crossbar needed to be bent.
dimensionally there is no external difference between the 3.0, 3.2 and 3.6 cases, all the differences were internal.

Just looking at the modified tin you can see how deep the tin tray is which is what i suspected being the issue for using the 1.25" spacers

here's what I currently have, I guess the last question still is can I retain the 993RS pulley?
or from another angle what are the specs of the 3.2 pulley or what ever pulley was used for the t/p, I doubt that a stock 3.2 pulley can be fitted w/o machining the crank snout.







Here's a pic of one of the buggers causing the issue

[Bill Verburg]

Is that a Rennline crossbar? and Sheridan f/g?

[Fredie]

Bill,
I am using the Sheridan “Tin” Order from Roger Sheridan directly to save a lot of money. Keep in mind he does these one at a time since he’s basically retired and living in Hawaii. But his turnaround is pretty quick.
As far your pulley is concerned, I am not sure if it will fit. But I hope and think it will fit a 3.2 console.
I was forced to replace my crank pulley as I was running the factory 993 3 belt with a single RS for the alternator in a 993 engine console etc…
Now I am using a Rothsport single belt crank pulley to fit the 3.2 console.

I hope that clears some things up.

Regards,
Steve

Crossbrace is from a Pelican on the forums here. Give me a moment to see if I can mine that out for you. He does a nice job. Fair price as well.

With my race car with a 964-based 3 .6L, I started out with a 964 engine carrier with solid mounts for the engine and transmission. The carrier was not bent. Then, I switched to an earlier carrier...it could be from a 1973 car...and it is not bent either. All I had to do was change out the mounting studs for the carrier change.

I am using a Clewett serpentine belt setup with a 1973 fan setup.

yes, I spoke w/ Roger Fri, he was one of several like you that suggested the 3.2 console/bar setup

now I hope that the single sheave pulley can be retained, it seems that it's only the longitudinal thickness that can be an issue.

this seems to answer the pulley ?

The pulley Rothsport offers fits within the 3.2 console and is the same diameter as the original 993 alternator belt pulley.
I hope this helps

Steve

when you say carrier do you mean the console that bolts to the engine?

here's a non AC/964/003 engine mount console





here a 3.0 console


and bar


and a 3.2



and bar

[winders]

I have a 3.0 or earlier carrier and a special crossbar.





But, I have used to have a stock 3.6 carrier and crossbar that was reinforced that mounted in the same position as what you see in the photos.

clewett serpentine?

Yes, Clewett. Since it is a non-standard config (3.6 crank pulley with 2.4 fan setup), Richard had to customize the fan pulley. The belt is a tad longer than I'd like it...but it works great.

Great info here , great thread. !!!

[1Bad86]

Danny's products are very nice.

I've bought several TI pieces from him.

I have one of his RSR cross braces now that I'm about to install on my 86.

There is a change to the way it installs though that I still need to figure out.

The motor mount bolts do not thread into the new cross brace mount like the factory design.
The new brace requires a longer bolt and nut to install into the chassis.

Not to hijack the thread but has anyone else ran into this issue and know what size nut and bolt is required?

I was just going to take the original bolt up to the hardware store and look for something longer.

We all know that any project requires 27 trips to hardware stores and auto part places that eat up so much time.

[SilverWT]

3.2 console and 993RS pulley. Fits with plenty of room.


3.0 console and 993S pulley. Fits, but not enough room to change a fan belt.

Thanks!!

Any pics of the installed engine and exhaust ?

early cross bars were threaded lat not, I don't remember the change over year
