Engine / Gearbox Mounts With Big Power

Just after some help on engine/gearbox mounts in my R32 GTS4, I find when under power the engine/ gearbox moves alot, which makes it hard to select gears when you change.

Are any other people having or had trouble like this?

What engine/gearbox mounts are other people using in their high powered cars, and does it fix the problem?

I changed to NISMO mounts all around.

What you have to remember is the stock ones in there (assuming they haven't been changed before) are now 15+ years old and have seen a fair bit of action in that time.

Buy new ones, put them in and notice the difference, you wont be disappointed :P

I guess a lot of people would be using Nismo.

Maybe you could get an engine damper. Even if it doesnt work well, its bling for the bay :ninja:

Damper's dont do dick other than take up space under the bonnet.

Get the new mounts and your problem will be solved :P

I went stock everyhing with my 370rwkw. Seemed ok to me even under full song @ the drags when i was full power.

Pulled it all out as part of the 26 conversion and all was well. No wear at all after some harsh km's.

Given though i had a stock crossmember that was modified to accomodate the RB25 box (as opposed to RB20 box which mounts differently).

So possibly the change that incorporated a better fit possibly?

I also had brand new diff mounts/cradle bushes aswell as i did have issues previously with things moving around a little.

Andrew,

Are you sure you haven't busted an engine mount?

When I dropped the RB30DET in I replaced mine with new ones from Nissan. 50,000km's later I busted the passenger side engine mount. :P

I believe it was most likely related to axle tramp. Subframe bushes sorted that.

No doubt with the GTS4 + Rb30 and near 400rwkw you will need something better. I guess you could try nismo failing that I don't know.

See if its possible to have some urethane's made up if not umm solids :S

had a poly g'box mount noticeably louder and more vibration in cabin compared to the nismo engine and box mounts I later changed to

g'box mount is easy to change with jack and stands, the engine mounts were a pain and that was with a hoist

we made up some solid ally engine mounts and we welded up the std gearbox mount. At 370rwkws the std engine mounts seemed fine, one race meeting at 400rwkws and we broke the p.s mount. So i figured we would need something remarkably stronger for over 450rwkws.

Best thing i noticed about the gearbox mount being solid was how easy it was to change gears. With the dog box, i found during one race i would crunch atleast 1 gearchange, after the mount change i didnt crunch any.

haha solid mounts in a race car you cant even hear the extra noise from vibrations lol.

      Pops when backing off throttle, rough-ish sound through rev range.

      By AdiR34 · Posted

      Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      By GTSBoy · Posted

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
