Hey guys

Just needed some advice...

I want to rebuild my boot so that my sub (12") fits into the right hand side of the boot. I want it moulded in so that it can be as out of the way as possible so I can utilise the rest of my boot space. Atm my boot is half filled with a sub box.

What I was wondering is, if I do the moulding with fibre glass, what is the likelihood of it cracking. I want to build an MDF frame and make the fibre glass mouldings around it, but I'm worried about cracking the same way fibre glass bodly kits crack over time. Is there a better way of doing it or should I not worry about this. I figured that with the extra rigidity of a good frame, this may not even be a problem.

Any advice or previous experience would be greatly appreciated :stupid:

Build it thick and it will be fine... Build it thin and it will crack and explode under presure...

You have little or nothing to worry about mate ... a fibreglass box will be fine! im making one for my tyre well now .. just for tips make sure you get all the air bubbles out first because they are a killer

For a single 12" subwoofer you'll want the wall thickness to be between 6mm and 12mm depending on how many bends, strengthening ridges etc are in it.

When constructing fibreglass enclosures here we utilise an extremely sophisticated testing procedure to see if the enclosure is strong enough. I put them on the ground and jump on them. If the wall flexes at all then it is not strong enough. :)

hey mate

here is a pic of my 10inch in the boot. to fit in a 12 is no probs just need to extend the front of the box forward another 3-4inches. (did that in a mates car) maes the edge of the box come in line with the boot itself.

might make you change your mind in fibreglassing a sub box.

That's an awesome job!

Now you've got me rethinking my design :)

Might take me a couple of weekends to put it all together. I'll post up some pics when I'm done :)

    • You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!
    • http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.
    • Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?
    • Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).
    • Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
