interesting though. Ive never looked into using fibreglass . i just want to keep this one simple and cover PVC in carpet. The small idea ive got is putting a thin neon light inside the tube and cut out the word SKYLINE or something into the PVC.Then use some tinted plexi/perspex to cover underneath. Ill heat it up and form it into a curve to fit and make it airtight. Hopefully it will look the goods and not tacky

Gotta get the pipe and also figure out the airspace i need for a 10" kicker sub. ill do some searching on this unless its allways the same for basic 10" sub like mine?

DEJAVU :wassup:

There is plent of it around mate, just make its no smaller than 3mm in thickness. I got a couple of pics for ya.

the thing is with the PVC is that it is a very thin type material only a couple of mm thick ( I know so is fibreglass but the way it is constructed is different) so unless you are planning to fill it with some sort of filler the sound coming from this will sound thin and almost sound echoed also this will also be harder to get a good seal on it...

I have seen thick cardboard tubing this could work well as long as you roughed up the outside surface and applied the fibreglass to that that will work ok and will give a better sound ( make sure the cardboard does not have a wax type finish if you glass it)

I hear what ya saying, thats why i built 2. One with PVC and the other with cardboard. I can't really see/hear any difference in them at all. I have SD composite inside both tubes and they have been sealed and covered with carpet. PVC that is 3mm thick or fibreglass that is 3mm thick is still 3mm thick at the end of the day. I know that they both have different material bases and what not, but if you make a tube out of cardboard or out of PVC then the same principles apply with the enclosure. You still have to have the same volume for the woofer, it has to be sealed and tight and some sort of SD inside to stop the resinance. They both have there pro's and cons but when it comes to the end of day you go with with whats going to work the best and cost the less. Fibreglass is very expensive and PVC/cardboard isn't. Its very easy to fix if you make a mistake with PVC/cardboard and it is easy to a degree with FG but you have to wait for it to dry and then that requires sanding, and starting again.

I think it comes to personal preference, but after talking to some pro installer/builders and the bulid instructions and materials that they gave me i can't complain and i think it will work well.

What ever floats ya boat at the end of the day :P

I built a fibreglass box for my previous car and I must admit I was very nervous about doing it as it was laid inside the car so 1 stuff up could of meant disaster and a long time on the grinder getting it out... but it all went well and have since done other peoples installs the glass and resin I got from a local boat builder I got 4 meters of glass and enough catylist and resin to do it and it cost me about $60 the wood framing I picked up from Bunnings at a cost of $10... but hey I like your ideas it has given me something to think about for my new car due to space limitations on the skylines

Thats the only draw back really with FG, if you mess up it takes a little to fix it up.

The 2 box's that i built cost me about $50 for the both of them, so that wasn't to bad i thought. I got some pics so when i get my cable back i'll post em up so you can have a look :P

      Hello sau 👋

      Thank you, 100% the intent. New coils were due and the 17" sixers look/feel loads better than the stock wheels. The aero options are so spot on.   Thanks for the warm welcome, all!

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      98 r34 gtt Been rocking my latest setup and car running like never before. Have put a good 200 miles on it since all the latest changes and additions. everything is dialed in and have been driving it a bunch.   However, all a sudden last weekend as soon as I pushed throttle passed 4k and the engine stumbles, (slow or fast acceleration) hesitates and doesn’t go above 4100 or so, like a misfire. Everything else seems fine. I had a “good” set of coil packs that I removed from car when I first got it when I changed them over to new coils. I swapped out current ones for those, but no change. I also changed the plugs, no change. Seems to rev over 4 when out of gear with no load just fine no “misfire”, but as soon as its in gear with a load of any kind, it “misfires” as soon as rpm drop back below 4 k it runs perfectly, smooth, starts, restarts and drives fine as long as I keep it below 4 k while in gear. All readings look fine, no CEL   Any idea as to what could all a sudden cause an issue when pushing rpms passed 4 k?

      Nismo GT Pro LSD configurations

      We're arguing semantics. I am saying 45 accel and a 55 deccel ramp are "2 ways". Even a 45 degree ramp and an 89 degree ramp is "2 ways", because it is literally... two ways. The cusco 55/30 ramp is a 2 way. It's two ways. I get it though - in normal nomenclature a "2 way" would be 45/45 or 55/55 or 60/60 i.e the same locking in both directions. And something like 45/65 would be considered "1.5 way". I would then say if we're getting into the nitty gritty then every locking diff is a "2 way" diff and we should not speak in 1.5, or 2 ways but ramp angles instead. Which ofc if one of those ramp angles is 90deg, that side is not doing any locking. :p So Nismo don't obviously sell 3 things. The fact of the matter that they only sell two items really goes to show that there's a 2 way and a "1,5 way" which is really a 1 way. I believe the actual lockup for the 'adjustability' of the GT pro is really just setting preload for when the ramps actually start locking up. It's not changing how much 'wayness' there is. It is (somehow) horribly explained. People just buy whatever diff and go "locks up good bruh" and that's what ends up on socials forever.
