R33 GTR gas boot struts

Recommended Posts

Just wanted to share with everyone some concrete information regarding replacing boot struts on R33 skyline, specifically the GTR but I am sure the information will be transferable. The reason I am posting is that there wasn't much information regarding pressures & the ability to remove the strut from the bracket (requiring drilling).

What I did ended up costing me $110.

Below is a picture I pulled from another thread, this is the part of the strut that is hard to remove. Very hard, but not impossible. What we did was use my 10mm spanner and wedge it in between the ball and the strut, then slowly work the it off. It looks like it's going to snap the strut and it ends up destroying it, but that's ok because new ones are cheap.

This is what mine looked like in the end.

We ended up putting 100nm of pressure in each cyl. It holds the boot fine with a genuine GTR spoiler. If I had to do it again, I would put 150nm in each to see if it holds any better, BUT that 100 works just fine.

Any questions please shoot them through.

What's 100nm in real pressure units?  You have given units of torque.  Pressure is measured in Pascals or multiples thereof (like kPa, MPa, etc) or in psi for knuckle dragging 'Muricans.  Or in N/mm2 (equivalent to MPa) or in bullshit units involving the heights of columns of fluid such as water or mercury.

It should be newton's, not newton/meters. I suppose it's just so common to say Nm he got confused.

So it's  not a pressure value but a linear force. That's how they designate gas struts.

Yeah sorry guys, I was thinking about that this morning and realised how stupid I must sound aha. The guy who did my struts didn't correct me, I believe it would be newtons.

EDIT: Re-uploading pictures of finished product.

Where abouts did you get this done? And these are new struts yeah? or did you end up managing to reuse the factory ones?

Hi all,

I am also keen to know where I can buy these as I have been looking and found nothing except a few used struts on eBay.

Any help would be appreciated...Every time I need to use my boot at the moment I feel like I have my head in a guillotine!!

I used a generic strut specialist. Old ones needed to be thrown out as there was no way they could be re-used. He just used the brackets from the OEM ones and adapted them to fit on the new struts.

I believe he just measured the extents of the struts and ordered accordingly, and put above mentioned pressure into them.
