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.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
