rb25 gearbox mount options - solid mount?

[nik.]

So im having trouble finding rb25 gearbox mounts. 

All i can find is polyurethane mounts which im not interested in as my last 1 turned to jelly (it is extremely soft and i believe the cause of my trouble shifting at higher rpm), otherwise all I can find is nismo gearbox mount. I cannot find any solid options

 

Can anyone point me in the right direction before i bother fabricating something?

 

 

Just for context - it is a s13 rb25 track car with solid engine, rear subframe and diff bushes as well as every suspension bush and my issue being shifting gets sloppy in the higher rpm

Contact Toughmounts and ask him if he has anything that could be inserted in place of the Nissan rubber block. What you would likely end up with is a circular crush sleeve type bush like you see in suspension arms. You'll probably need to do a little welding.

I'd have a look on his site for you, but he only has facebook and I will not ever click a link that takes me to that seething shithole.

I would have thought there was an off the shelf item being one of nissans more popular gearbox

I appreciate the input but i wont buy something if i still need to weld and work it. i may as well start from scratch.

 

I thought there would have been a preferred mount for higher hp applications or do most run a nismo mount?

I run a gktech solid mount 👍

I previously used a Nismo mount, polyfilled the gaps. No issues with it. Had put a GKTech one in 3-5 years back ( I now do less than 2000 k's a year in this car) and when under there this weekend, found it has crumbled apart and the goo/crumble stinks like nothing else, smells horrendous. Will be putting the Nismo one back in for the time being but open to suggestions. Not keen on any more GK Tech products at the moment, also found one of their engine mounts has broken a stud, just snapped when I went to undo it. Also not that old, minimal k's.

Let them know.

ok I got to say - despite all the 'we welcome your feedback' crap, every time I've contacted them giving the details of my issue and the reasons why, I get pretty much a ' oh well that's how it is' type of reply. This is over multiple products since I've bought from them for many years, and never had them actually be interested too much in feedback. IE the mount stud breakage would likely get ' it's over 12 months old' , we don't know how it was used, etc. I'll just replace the stud.

Hmm. I've gotten pretty good outcomes from talking to them about things that I've had go wrong or ideas for improvement. Have had a lot to say about the R32 FUCAs, and they have sent out some replacement parts for those, gratis, on a couple of occasions. Mind you, I have bought a couple hundreds of $ of replacement rod ends for them too!
