Default Installing STi motor mounts - having problems

So I'm replacing my motor/tranny mounts with STi Group N motor mounts. I started with the front passenger side motor mount - after messing around to get the rear bolt off, I finally wiggled the old one out. The bracket on the STi mount is definitely bigger, though, and I can't seem to get the whole thing in there. Anyone else encounter this?

It started getting dark so I'm leaving this for tomorrow morning.

jey,

Yeah, the Gp. N motor mounts are bigger. Check out the comparison shots here:

Hopefully you at least have wheel ramps, and a jack to take the engine weight off the mounts. I just did the Gp. N transmission mount tonight. Not too difficult. I think I'll have Ron do the motor mounts.

We met at Ruby Tuesdays last year, I think, I was driving a black 91 Legacy turbo.

I do have the engine jacked up with a bottle jack - I think it's as far as the engine will go cause when I jack it up more the whole car goes up. I dunno, I'll give it another shot tomorrow morning cause it might be easier to get in there now that I have the oil return line from the turbo taken off too.

Yeah, I remember the meet at Ruby Tuesday's - thanks for replying!

Update - went about it a different way now, got the mounts bolted up onto the engine, but now the bolts on the mounts don't line up with the crossmember. If I lower the engine the studs on the mounts just hit the crossmember instead of going through. I read on scoobymods that you kinda have to shove the engine back a little so that it lines up, but it's not going anywhere. Hmmm... any suggestions are appreciated....

I'm pretty sure they aren't in backwards either.

Dont' know if you've done it already, but pull off the tranny mount. That'll give you a whole lot more wiggle room.

Just pulled off the tranny mount. Just messing around with it for a few minutes it still doesn't want to move. I'm out of ideas again, :sigh:

just did those on my cousin's legacy. we had a little problem with the stud holes not going in but i just rocked the motor around and they fell right in. did it without ramps. note: you can get your whole hand in there to get the rear bolt in and out if you reach over the control arm and go in from there in case you havent done that yet.

Yeah I didn't have ramps either - just jacked up the car a little and put it on jack stands.

I finally got it to work. I discovered the problem - with the engine at that angle the intercooler was shoved up against the firewall and brake lines, and pushing the engine a good 1 inch towards the front.

Another interesting thing - as I was unbolting the tranny mount yesterday I noticed there was only 1 nut to undo for the stud that connects the tranny mount to the center tranny crossmember. I didn't think much about it, but then when I pulled the whole crossmember off today to replace the tranny mount, guess what I saw!



As you can see, at some point before I started this whole thing, one of the studs on the tranny mount had broken off!


Well, looking back on it, here are some things I came across that might be helpful to people in the future:

I followed the scoobymods instructions, and following them was pretty optimal except for the following

- There is an advantage to not using ramps to lift the car is that a pretty basic bottle jack is tall enough to lift the engine and tranny up - I had some problems with that when I had the jack stands up too high.

- I got confused by the scoobymods instructions on only doing one mount at a time. You definitely have to undo the nuts at the bottom of both motor mounts in order for lift the engine sufficiently high enough off the front crossmember.

- If you have a big intercooler on your car like I do, you have to remove the intercooler before you even lift the engine up. The intercooler caused me problems.

- Once I got the intercooler off the engine moved a lot easier. Two people helped me by just pushing on it and I was under the car guiding the motor mount studs until it lined up with the crossmember. It may be easier to do one side at a time.

Mine didn't break off while changing the mount. It was already broken when I got under there to take it off. No wonder my tranny was thrashing about lately.
