STI Engine / Tranny Mounts

sebtarta · 03-17-2005, 11:07 AM

Well, I finally have taken pictures of the stock pieces. Most of us have seen the after market mounts around the net.
Here it goes,

Engine Mount Stock

Engine Mount STI Group N

Tranny Mount Stock

Tranny Mount STI Group N

Pitch Stock

Pitch STI Mount Group N

Well there you go, there is a HUGE difference when this was done. Once all the mounts were installed, the car felt different, the clutch response difference too. I am very happy I did this...
Good luck,

I'm in the middle of doing this now. I've already done the tranny mount and have the engine mounts sitting on the toolbox. Were the engine mounts pretty straight forward?

Just for anal-retentive clarification purposes, you may want to edit the thread to state "STi Group N" for each piece, since the STi uses the same parts any other Impreza uses.

Scoobymods has a good writeup on installing the engine mounts. I did the transmission mount myself but left the engine mounts to the "experts".

staticfritz · 03-17-2005, 01:25 PM

wait, is the stock sti mount the same as the rs mount? somewhere between the rs and group n? same as the group n?

yes the stock sti mount is nothing special...
just made for a 6 speed

the sti does not come with Group N hardened mounts...

I found it does. The stock is a thin flimsy one, and it prevents the engine from rocking back and forth.

Any opinions on the Group N mounts (engine, tranny) vs. what Cusco offers?

Thanks!

I've done 2 engine mount installs. First time it took me a while. Second time I jacked the engine up higher and had an easier time, largely because I paid very close attention to how the old mounts came out. If you don't do this then it can take a while to work the new mounts back in. The scoobymods site has great instructions. Don't forget to unbolt the pitch mount to let the engine rise higher. I've done this mod on an '02 and an '05 WRX. Steps were the same. I recommend saving one of the cardboard boxes in which the mounts were shipped. It makes a great head prop when you're under the car.

I've done this twice because I bought a new WRX after someone rear-ended my old one (thank god insurance covered the cost). I couldn't stand the spongy mounts in the new car so I did the mod to it as well.

[edit: sorry I just noticed that this is the non-turbo forum. The mounts look the same as the WRX mounts so hopefully the scoobymods instructions will still apply]

anonymous_wolf · 03-23-2005, 03:36 AM

just got my engine/tranny mounts installed
there IS a difference...
1. rough idle, shaking in the same way as if the engine is gonna stall in first gear. but the shaking goes away once engine speed is abt 900rpm
2. the engine doesn't flip like a dead fish anymore!!
3. the car doesn't shake as much as it used to be when i do a bad shift (ie, not perfectly matching the rev when shifting). also the jerkiness in first and second gear is reduced.

as for throttle response, i'm not sure coz i installed light weight pulley at the same time, so i suppose the pulley does more on giving better throttle response than the engine/tranny mounts.

overall, a worthy mod i'd say, car feel much smoother except at idle, which is not unbearable either.

nonetheless, i think i should get those rear diff lock soon, coz i can feel the rear diff taking the shock when i do power shift.

Yep, I have the same feeling when its at idle, and when i jsut let the car rev down at 2000 rpm the tranny shakes a bit...but i like it.

In terms of the diff lock, have you seen any?? Where could I find some on the web?

thanx

I'm not sure personally, but I'd say the Cusco stuff might be more comparable to, say, an STi Group A type of mount.

Would anyone agree? I only say that because the Cusco mounts, if I'm thinking of the same ones you are, are pretty dang stiff and solid, whereas the GpN bits are really just hardened versions of stock. I mean it's more complicated than that, but you get the idea.

As for the "STi" vs. other Impreza question: STi mounts are exactly identical to the mounts on any other stock Impreza, save for the fact that the shape's different on the trans. mount to accomodate the 6-speed. Hardness, etc. is the same. You have to explicitly buy "Group N" to get any improvement.

=S2=
STi GpN engine mounts (engine seems a bit less "rocky")
STi GpN transmission mount (didn't notice much except less shifter shake at speed)
Stock pitch stopper (I hear the GpN one rattles the dashboard quite a bit, anyway...)

sebtarta · 03-23-2005, 08:06 PM

I really dont have the differences between the Cusco and the Group N. But I think they might be almost the same. The only thing I know is that the Group N is made out of a hard neoprene, giving the ability of a rigid mount but also able to absorb vibration.

I am happy with my mount, cannot complain at all. My friend mechanic that works with me with the car, he drove the car long time ago without the mounts. Then after finishing installing all the mounts, he took the car for a spin, and instantly he felt the difference. Most in particular in the tranny.

Good luck,
