Hey guys,

For those with R33 gtst's, and harnessess - where have you bolted the shoulder straps to in the rear of the car?

I have used the bolt holes on the backseat from the back right hand seat, (where the existing seat belts would go if the backseat was there) however the angle of the harness is around 45 degrees...looking at the cams manual, it says the acceptable range is no more than 40 degrees...

So what have others done?

Is it enforced strongly also?

Pics would be handy if ya have them :cheers:

Thanks guys,

Chris

Chris its rarely enforced strictly in a road car.

However one option is a purpose made bar that goes from tower to tower across the rear parcel shelf. I have made a fair few of them for R33's and they work fine.

Chris someone (and I can't for the life of me remember who) make a parcel shelf strut brace. If you can find out who makes them great or go with Brads idea. The rear seat belt points suck,,,in a roll-over your shoulders are subject to way to much force.

Just keep in mind cams rules are minimum requirements,,,always try to do better.

Cusco do parcel shelf bars for the R33 from memory.

There okay and you can wrap a harness around them, but not really strong enough in my opinion.

Ill try and dig up some photos of the last one I made but basicly it was 38mmOD 2.5 wall thickness CDS (same as minimum spec cage material) It had decent sized mounts and the harness mounts were the usual eyelets with welded in thread bosses.

Also did one for an RX7 not to long ago (actually you'd know the owner Chris, Craig Baker)

Nah Brad It wasn't the Cusco one,,,I bought one off Johnny at UAS some years ago that was good quality steel that would do the job.

I actually gave it back to him thinking it was wrong. Strupid me.

Really the only way to secure the shoulder belts properly would have to be a half or full cage.

But after saying that the series 2 GTS-T's have mounting points for a strut brace in the boot which I use. Cutting the rear fire wall to run belts through there would be another way.

The Skylines parcel shelf is no way strong enough in my opinion,,,but the strut towers would be.

Hey Chris,

My harness is mounted in the back seat belt bolt holes also and i have roughly worked mine out to be 33 deg below horizontal or 57 if you are measuring from the vertical postion? When i fitted mine i never checked cams i followed the instalation guide that cam with mine ( it is a Takata harness ). I can post up pictures if you cant remember what it looks like or you are more than welcome to drop in on your way home on Sat and have a look.

I have attached the page out of the manual for you. Would mine pass?

    • Can we see a scan of the original quote? The problem with engineers (and by this, I mean, all engineers across all engineering industries) is that there are "engineers" and there are "engineers" (you'll have to imagine the two different vocal emphases on those two versions of the same word. Engineering is a mindset - your farm kid who spent his life rebuilding the tractor will likely make a good engineer. The farm kid who spent his life taking photos of butterflies.. perhaps not. But on top of that mindset, the modern engineer has to learn how to write so that there is absolutely no way of being misunderstood. Proposals/budget estimates/quotations are one place where this is absolutely vital. You have to delineate your scope of supply with extremely hard boundaries, and anywhere where there is any possibility of not being able to have such a hard boundary, you need to write language that will cover you from scope creep, cost overruns, the inevitable interference of the client or their "engineer", etc etc. Now, if your clients are the BHPs and the Rio Tintos of the world, and similar, then you get good at this. If you are an automotive engineer, pitching work to the great unwashed masses, your skills in this area might not be well developed, because you're only dealing with knuckle draggers trying to get a big block legal in a Torana. And when I say "might not"....I'd suggest there's a better than even chance that any such skills might be completely absent. So, we might be able to look at your quote and see what the opportunities are for rebuttal.
    • It’s an rb25 so a gtst and I’ll get that valve
    • Thank you for this my turbo doesn’t have the nipple so I’ll get one installed in the turbo to Intercooler piping. I’ll get everything I need and locate it all using the information you both gave and get back with an update. 
    • Please do not connect it to your manifold. If you do, as GTS suggested please record the lot in 4K with good mics attached.   On the factory Skyline, there's a upside down pipe that allows it to breathe, looks like this   
    • For me I'd need some serious justification for why it has blown out.  Have you questioned him on it?  To be honest if you didn't question him right from the get-go on the first invoice that was already way over the initial quote and then you've (presumably) then paid another $1375 on top of the first invoice, then you're pushing shit uphill to get a favourable result now... It was years ago I last got an engineer out but it was around $450-$550 per visit.  That was just to inspect each progress point he gave me for the project.  Is he just doing progress inspections or is he providing engineering diagrams, technical assistance, etc??  If he's not, he's a filthy rip off merchant.  If the $3100 is the final sign off then you need to cop it on the chin, pay it and move on.  If it's not, piss him off and get a new one.  Not many Jeeps I'd value at $10K full stop let alone just engineering fees on a written off, half actual value WOVR Jeep....
