I am doing a 5mt swap into my 1995 leg and the stock trans mounts are shot on the donor car. are the STi mounts the same? I was thinking about replacing the motor and trans mounts with STi mounts when I do the swap as I will probably be removing the engine when I do the swap to replace a few things to hold up to my turbo kit a little better.

yes, it will work as long as you have a manual
*edit* RaceComp is saying that you need a MY93-04 mount for it to work with a 5spd

what do you mean a 93-94 mount.

honestly, that confused me too...i thought the sti mount would work as long as you had a manual :? probably shouldn't have added the edit :lol:

lol :lol: :lol: Alright, well I am going to pick those bad boys up as soon as I get some money together here. This automatic is driving me nuts. Now I just need to find a good deal on a performance clutch to hold up to the turbo :)
Thanks for the quick reply

no problem, i just hope i'm right! :lol:
i'm sure one of the other guys here will correct me if i'm wrong :oops:

yeah I wont have the moeny for a week or so anyways so I have time to be corrected. but I dont see why they wouldnt work as the sti motor and trans bolt into the car so the mounts and mounting points must line up, right?

I'm using the STI Group N tranny mount for MY02+ WRX on my '92 SS. AFAIK, they are all pretty much tha same unless maybe if you're running the STI 6-speed.
I got mine from RaceComp Engineering too.
Get the Engine mounts too while you're at it. They make a HUGE difference.

yes I plan on doing the engine mounts also. I am eying up a pitch stop bar from function 7 also but not sure if they are the same. The bar that goes from the firewall to the transmission. because the donor car has alot of slop when you press the gas the shifter will move about 4 inches back and actually fall out of gear once in a while

thanks for clearing that up matt. didn't think they made two different mounts.

If you are pressed for money, you can simply fill the void in the existing tranny mount using polyurethane - that gives you a super-stock type mount.
It's a good compromise and fulfills the same function.
PS. Any group N mount will work with the 5spd.

yeah, I know I just figured I would pick up the sti mounts or any after market ones for that matter because it will be apart. im pressed for money but have all the time in the world, so I am just gathering the last few bits I need to do my 5 mt swap. I still need a clutch so when I finally get all the parts I will do the swap then. no hurry, you know. rather do it right once than take it apart again later to fix things that could have been done

I just bought the STi Group N mount for my '95 Legacy. I'll let you know what I think of it as soon as its installed :)

PS. Airtools are thoroughly recommended for the transmission mount. Especially if your car is older/has a lot of miles.
I had to use a 650psi impact wrench.
NewGenSTi
02-08-2006, 12:28 PM
:) yeah I would have figured that already. well my car has about 130k but it is extremely clean there is just about no turs on it at all. but the donor car the whole underneith is rust... anyways I have an 850psi here and I have access to one thats about 1200 from my friends bus company. so there shouldnt be a problem on that issue :)

No problem Jess. :)
My pitch stop is metal. I'm not totally sure about those poly ones.
When I did my mounts the bolts popped loose easily with my breaker bar. If you have air tools then by all means use them though. =)

NewGenSTi
02-08-2006, 08:51 PM
yeah, but its $100 and it would be hidden under my intercooler so I think I might just pick up a new stock one or at least new bushings for my stock one. I dont know how much of a difference it could actually make.
belladonna
02-09-2006, 08:23 AM
i was wondering the same thing about the pitching stopper. i was toying with the idea of getting one, but if it doesn't make a lot of different, just replacing the bushings in the old one would be better.

It's only supposed to prevent the engine from pitching forward/back on hard acceleration/braking movements.
I believe the STi pitch stopper is about $70 online.
It's not something that has to be done now, the stock one is adequate, and the pitch stop can be easily installed later.

the reason I am looking at it is because I am doing a 5mt swap and the car I am taking the tranny from when you press the throttle down and you are driving the shifter pushes back towards you and even pops out of gear sometimes. so I believe this is the problem
Huffer

That has nothing to with the pitch stopper - that has everything to do with the internal transmission or the shifter linkage.
A pitch stopper is just a pitch stopper. Not worth the extra expense at this stage of the game.
NewGenSTi
02-09-2006, 01:27 PM
I dont know, I was thinking it was a combination of the trans mounts and the pitch stop. the tranny shifts smooth and everything but the shifter pushes way back when you get on the throttle. I dont know I am pulling the trans this weekend. I will better inspect it when I do. I also have access to another transmission so I am not all that concerned.

pitch stop is ultra cheap on subarugeniune parts.
Actually so is the tranny mounts and engine mounts.

Can ya explain this more? What is the problem when you are in a gear, let go of the gas, and the car feels like it shakes back and forth? I just wish the car would do this smoothly.
NewGenSTi
02-13-2006, 03:27 PM
my problem is when I am driving the car and you put it in gear the shift lever moves when you give it throttle. I have looked into it a little more and I noticed it doesnt do it in 1st 2nd or 4th
only in 3rd and 5th which are forward gears
Now I was thinking it was the pitch stop because if the whole transmission wss moving back that would cause the shifter to push back like it does, but it would not cause it to fall out of gear for the simple fact that the whole assembly along with the tranny moving would be the culprit, and also it would do it in every gear. My problem lies within the transmission I believe. I am going to take a better look at it once it is out of the car and maybe have a professional take a look at it and give me their thoughts on the subject. If worse comes to worse I will probably use the trans as a core for a reman.. I have come to the conclusion that I more or less knew this all along but was trying to convince myself it could be somethign as simple as the pitch stop. lol

There is always some vibration in the gearshift lever - providing it's not sloshing allover the place and jumping out of gear, there's nothing wrong with it per se.
You might want to try tightening up some of the nuts/bolts under the gaitor though.
NewGenSTi
02-13-2006, 07:57 PM
3rd and 5th pop out of gear when you press the gas
even if you hold the shifter forward with all your might.. lol

Yeah I had to use a 3-foot long breaker bar to get my bolts loose :lol:

So let me get this straight, sti "N" trans mounts will fit say a 99 legacy OB 5sp? will the sti motor mounts work for said car too? Iam exeriencing drivetrain vibe and when warm binding when turning... any info that is helpful/clearifying is welcome... :? [/i]
NewGenSTi
03-01-2006, 08:40 AM
ok the mounts should work for any of the 5spd transmissions, and the sti group N mount will be stiffer than stock so its going to put more drivetrain vibration into the car. But I dont think the stock mount would cause a binding issue

Not the clutch. when I pulled the trans the clutch looks like it was recently replaced because there is no wear on it at all, and all the bearings feel new also. The stock mounts didnt look bad either so I think I can scratch that idea. I am going to open up the cover on top and see if I can see any loose/broken parts. But I am probably just going to take the trans and have it looked at and see how much for a total rebuild as I will be turbocharging my car in the spring and wouldnt want to ruin the fun by having the new trans let loose.. lol

Yes, and yes.
New mounts won't do anything to alleviate the binding when turning.
If you have a 5MT, then you need to try new fluid and see if your tires are the same overall height.
If you have a 4EAT then you need new AT fluid, Lubegard ATF Protectant AND check to see if your tires are the same overall height.

If you have a 4eat and are getting binding, then there's a pretty good chance your duty solenoid C is probably going bad. Pretty common problem for Subie 4eats.

point of clarification:
STi stands for "Subaru Technica International" These mounts are not from the WRX STi, they're just made by that performance division of Subaru. They're hardened mounts that hold the transmission much better than the stockers, which tend to flex and bend a bit more.
So yes, STi GroupN 5speed Tranny Mounts will work for any EJ series 5 speed Manual transmission.

The poping out of gear thing dont force it to stay in gear, I tried that and ended up locking up the trans, was stuck in nuetral between 5th and reverse. Someone said syncro went...???? all i know was i had to replace trans...
So fluid is not too old, less than year, tires are all same size, with exception of maybe preasure issue. I was thinking if the mount was bad it would allow the trans to move causing the binding, either that or i have damaged the rear dif....hope not
Thanks for the info though

You haven't said if it's manual or auto.
I doubt it's a rear diff.

Its a 5sp manual. I would like to think not, but the binding comes when i turn. Now i read that it could also be a dry inner cv joint(s)... at 157k and the way I drive it may be anything. Just worried as when i swappd trannies I put Mobil 1 in the rear dif, not more than a couple months later drivtrain vib. Well maybe not the way i drive as much as what I subject my car to.... water, mud, deep snow, etc....

sEMI thread-jack
Are the Group N "STI" engine mounts mounts available at US Subaru dealers or are they not a part that Subaru actually carries and more of a performance shop part? Do they have a Subaru part number?
Thanks

dunno about your dealership, but
www.subarugenuineparts.com (http://www.subarugenuineparts.com)
is actually Chaplain's Subaru in Washington, and dealership, that carries all of the STi parts. I believe some dealerships carry cobb parts that are "authorized" by Subaru so they don't void the warranty.
Huffer

Cobb tranny mounts are STi mounts with a $10 extra price tag.
Another Cobb marketing scheme.
Any dealer can get the parts, but it's easier to order online.
SHOfast
03-03-2006, 01:13 PM
Thanks. I am going to see if the dealer can get them for me. I don't really want to wait for the week long shipping I get from SubGenParts. I doubt they will have them but I think would be great to get these in before I get too much further with assembly.

the dearlership will have to order the parts anyways. I would go through SGP, because the parts manager for the dealership is going to tell you that the tranny mounts are for imprezas only, because they don't have a Part # for the Legacy (even though they're all the same).
