Tilting Tranny for more ground clearance

MickeyMouse · **Posted:** Fri Jun 26, 2009 10:57 pm

I am changing my engine out to a Subaru and I need to raise the engine up to clear the oil pan. I have heard that some people have lowered the nose of the tranny to raise the engine. To do this, I was going to drill new holes in my nose cone bracket. Is 1 inch enough?

I was also wondering if I should/could raise the tranny at the rear bracket. Will that help raise the engine?

Thanks
Dan

cv joint angles may be too much

I did this same mod,, when I went from 3 rib to 6 rib,,,to keep from scooting the engine back I used a 3 rib bell housing,,plus,,,I cut the mounitng bracket off of the torsion and ground it down at the welded area to fit the torsion closer,,,thus the rear tranny mount was nearly the same original location,,,except raised by adding some 1/8 flat metal for raised mounting bosses,,,, then I lowered the front bracket by relocating the bolt holes as you mention,,,about an inch,,,,I think,,,any way it was as much as I could get before the nuts hit, remember to teeter the tranny so the cv flanges ramain at the same location so as not to change the angle of the axles,,,good luck

I did that too, I moved the rear an inch and droped the front one and a half inches.

look at the yellow trans in the pics.

Use your drive flange as the pivot point. This will not change your cv angle and will give more clearence.

Lower the trans till the cv's touch the frame horns, then tilt the nosecone till the shift coupling almost touches the rear tortion. That should get you close. You can always lift the motor up in the back too, but don't angle the whole thing over 10*.

Carfull on how far you drop the front of the Trans. If it ends up lower than your frame it will get damaged. Make sure you add additional protection under it. Even with an additional heavy duty plate I still broke mine.

Thanks everyone. Next week I get my 6 rib and I will begin modifying the brackets.

If I add the 3 rib bell housing on my 6 rib tranny, would I use a 3 rib or 6 rib starter?

This mod is so you can shorten the assembly a smidge and use the 3 rib starter, the 6 rib bell is stronger and longer,,and has a beefier crossbar,,,I run a 3 rib bell with aftermarket crossbar since I run a stage 4 PP,,I never had any problems running the 3 rib bell with ej22 and stage 2. 6 of one,,half dozen the other.,,my .02

Shorten your oil pan 2 inches, it makes a huge difference in clearance.
You will still not be happy with the clearance unless you have race preped 930's and run them at their max angle.
Also with the shortened pan, when you drop off a very steep hill shut the engine off, to prevent oil starvation.
You might as well get a high torque starter now.
I run a stage 2 kep with the kush lock plate, because the flywheel is too expensive to eat up with the puck disk.
Oh yea, when all those vws are reving , I love to hear the suby sounding off on the rev limiter.
The sound just stands out in a crowd.
I've ran a 2.2L suby in my woodsbuggy since 2003.
When it's all iced over and freezing, there's nothing like walking up to you buggy, reaching in bumping the starter, and it just sits there and purrs.
I guess you all can tell, I LIKE MY SUBY.

Need to shorten or change the input shaft for a 3/5 rib bellhousing install on an 091.
Use a Bosch starter SR15 (manual) or a SR17 (automatic) for the 3/5 rib.
Use a SR 87 if you stay with the 091 BH.
As mentioned, the 091 bellhousing is stronger than the early smooth version 3 rib BH.

With the Suby adapter you don't need to change the input shaft. The adapter is about 1/2" thick so the 091 input shaft is fine as is. I am using a 3 rib bell housing with my eg33,,,it has the hanging ears.

If he uses the 091 BH and the 091 input shaft he will come up short if that adapter is 1/2" thick, correct?
That would mean he has to change the BH to an 002 style and keep his 091 shaft.

I couldn't say,,,maybe the other suby guys would know,,I have always ran a 3 rib bell housing.

I should receive the adapter plate on Wed or Thursday and I will be able to try it out. After talking to Kennedy Engineering, it is my understanding that the flywheel will be in the correct position for the respective bell housing. An 002 will require an 002 starter and an 091 will require an 091 starter.

At this point, I think I am going to keep my 091 intact and not swap out the bell housing.

Thanks for all of the input.

They make up the difference in the flywheel hub length.
