Anything preventing this? (engine/tranny mount discussion)

[e1_griego]

Bought a delrin transmission mount from ebay (link) and then realized that I have to give up my exhaust bracket mount (herp derp).

Anyhow, is there anything preventing me from installing this JGS style by cutting the rubber part out and retaining the metal bracket? I assume not, but just checking with people that know better than I.

For reference, JGS poly mount install instructions:

My new PBM downpipe bumps the chassis in 1st gear, presumably because of dead stock mounts. Going to put in JGS poly mounts (or the drift freaq ones on zilvia) come payday. But I'm hoping the solid trans mount will take up a lot of the slop. Would I have been better off with poly?

I just welded a bracket from the downpipe bolted directly to the transmission. Keeps stress off the turbo by having it move with the engine and trans. I'll try to get a pic tomorrow.

[e1_griego]

Pics would be great.

Ideally I would just run the new mount in the stock bracket. The PBM pipe has a flex section.

Don' remove the exhaust bracket on the tranny. I did and it FUBARd my exhaust and helped crack my header cause there's nothing to support it until behind the rear axle.

[e1_griego]

Yup exactly. Just trying to run a better mount and retain the bracket . I've blown the t2 gasket before

I'd try to keep the stock mount so you have that bracket and not sure I'd trust the delrin with engine mounts that move even a little... too much movement might crack the delrin.

I used 3M window weld a few years ago on my mounts but the stuff is beginning to peel away from the mounts making them sloppy again.

I read someone used PL Premium Poly Construction Adhesive in the yellow tube with good results... $5 from HD, stiffer and better adhesion than window weld. If I can manage to get all the old window weld off my tranny mount I'll try it out... if not I'll probably go with the JGS rubber mount.

I bought a block of polyurethane from an industrial supply and cut one on the band saw. it's not much different than the one pictured above, and fits inside the existing metal parts. the thing is so damn stiff that my brain rattles at idle now. it doubled the interior noise of the car just with that mount change. I would suggest going with stiffer engine mounts and leave the tranny mount alone. see how you like that, then make changes from there.

[e1_griego]

Hm, fair enough then.

Maybe I'll just do JGS everything, or try out the Drift Freaq poly mounts from zilvia.

[e1_griego]

I said screw it and bought the drift freaq poly mounts.

I think I will try a poly tranny bushing too, just mounted like the JGS one inside the stock sleeve thing.

Anyone want a delrin tranny mount?

[CodyAce]

THese pics are VERY old, but for reference it is the same. I just made my own bracket to bolt to the downpipe. Works great.

[e1_griego]

So, I bought the Drift freaq mounts.

Loved them, until they failed. 20 autocross runs and then this:




Hopefully he's sending me a new one so I can swap it out. Not super impressed. Hoping just a defect? It was heat wrapped.

[CodyAce]

damn that sucks, I JUST put a kit on a local drift kids car too


PS: Clean that engine bay, damn hahah

[e1_griego]

Bah, whatever

It's really not that dirty -- flash does it no favors. The frame rail has had a bunch of ATF splatter on it so it's collects dirt like whoa.

Driving > cleaning lol

[McCoy]

Sucks... hopefully if you get another one it holds up better. I installed the JGS poly mounts earlier this year, they seem to be holding up fine after 3 track days.

I'll probably swap out to the JGS rubber mounts next year though, the poly one's are a little stiffer than I like for the amount of vibration I'm getting at idle and certain RPM's on the highway (3.5-4K) cruising.

[e1_griego]

These were great until they failed.

Minimal vibrations at idle (though I have idle @ 1k, not 750rpm) and maybe a bit more noise/vibration (though a lot of that is prob from tranny mount).

I guess I have to pull this one out, send it back to him and wait for him to send me a replacement. Sort of a pain in the ass.
