I'm going to design my own boot floor template so I can make one out of MDF. The factory one doesn't even fit properly! It uses bits of foam to rest on the spare tyre (which I've removed) and the rest of it doesn't appear to line up with any of the ridges in tbe boot.

Before I go ahead and do this though, I just wanted to know if anyone else has done this before? I basically want a snug fit into the indentations around the spare tyre well so it won't move around, and I can then bolt a sub to it (or at least clip it on for easier removal of the 2 separate items). I also want to make it a lot sturdier than the factory cardboard stuff so that it doesn't require the spare tyre to give it stability.

If no one's done it I'll just do my own from scratch and upload the finalised plans for anyone interested.

I'll see if I can get some measurements on the weekend, and hopefully buy the MDF too. I'm going to make it as thin as possible while still making it sturdy, because I don't want it coming through the rear seat panel and slicing my passengers in half! :eek1:

I don't think I'll be able to actually make it this weekend though, I still need to find a jigsaw. A friend of mine who had one moved to England recently :D I'll tell you how I go on the weekend.

Well I had a good look the other day and I don't know how this is going to work. There doesn't appear to be any lip around the edge for the floor to sit in.

What I might do is make something with legs on it so that it sits inside the spare tyre well, but I don't know if this is going to work if the spare tyre is in there.

Ah, I just had a brainstorm! Instead of legs to support the whole thing from the bottom of the tyre well, maybe just little bits of wood to keep it in place around the lip of the well to stop it sliding around. Then the actual floor itself can be any shape at all and it shouldn't shift around.

Anyway I'll see what I can figure out eventually.

Yep, as does the factory item. I'm just hoping to design it so that it won't jump around too much and if it does it will land back where it started. Perhaps some foam underneath to help absorb any clunking sounds, or even velcro to hold it down? I could always use nut and bolt type fasteners or clips, but that'd probably mean drilling into the floor of the boot and I definitely don't want to do that.

This is turning into a major project, why couldn't they just design something good from the factory? (sigh)

Hey JimX,

I actually did this on my first R33, Didn't take down measurements of anyting but ;(

I would be planning to do something on mine for a while too :D

What i would do is get the original carpet, put it over a piece of MDF or watever you wanna use, trace around it with a pencil, and then start jigsawing :)

To stop it from boucing i would then goto HARDWARE HOUSE and buy some of that Velcro thats double side..(make sense?) the Velcro was $5.00 a meter i belive.

then stick one side of the Velcro down to the floor and then one on the actual MDF.

As for spare tire issue, i would just get some foam from clark rubber and fill it up to be the same hieght as the rest of floor.

I also wanted to make one for the rear, battery cover thing, pretty str8 forward that one but things is how to mount is.

As i wanted to have my AMP secure on to there.

Let me know how u go,

If i get bored i mite start making one... :)

couple of months back i took out the spare tyre and drove around without it. then i had to do some grocery shopping, buy some drinks and stuff like that. couldn't put it on top! coz the covering that is there is so weak that it just caves in!

so yer, i reckon this thing is a good idea. i'd be interested in it.

i don't think it bounces around that much with the carpet covering it.

I'll vouch for the "tracing around the carpet" idea..

I did this in my sonata to construct a new boot floor. and it works a charm, i user 12mm MDF, sturdy as a rock!

I sunk my amp into the tyre well, flush with perspex and neon's to the floor.

I then had the 2x12's facing the back of the car, pretty much where the flimsy battery cover thinggy is in the Skyline....

Don't forget to secure the MDF to the boot floor. Velco still lets it move around a bit and didnt work for me... I just used countersunk self-tappers, then carpeted over it all in light grey..

looks the sh*t too :)

If your going to use a sub in there, ply wood is ghey, it's too thin and rattles VERY easily...

Good luck guys..

I have actually just done this sort of thing in my car.

I basically used the existing carpet as a template to cut the mdf. I stuck 2 seperate pieces with liquid nails onto the corners/sides to act as like a fixed mount. Then I built a hinged 'lid' to allow access to the spare tyre and fixed the hinges to the corners pieces. It seems to work pretty well and once carpeted looks pretty neat.

I know that the corners pieces are now fixed, but the beauty of liquid nails is that it can be broken if needed, but is otherwise pretty sturdy. I aslo used hinges with removable pins so that the lid can also be removed. With the hinged lid setup I also have access to the spare tyre.

It was near impossible to get an exact match up with all the contours, but with the existing carpet you can get it pretty close with the timber, then wack carpet over the top and kinda free cut it so it matches up cleanly.

I chose to use mdf because it is easier to cut than ply and doesn't splinter, which is important because there are a lot of difficult curves to cut with the jigsaw...

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
    • Shock tower brace is in +5Kw....LOL
