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.

      What brakes on R34 GTT(Europe)

      By Duncan · Posted

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
