another thing to remember when masking it, start from the bottom to the top so you don't have any leak of FB, I put 2-3 masking tape on my boot before fibreglassing and chuck some plastic (bins or even normal plastic bags) to cover the rest of the area, the last thing that you want is to get FB all over your car body.

If you are making a flat surface FB, use a thin wood (from bunnings) to help shape it up and the rest leave it to the bog :)

how was the mould taken out, easy??

Sorry bout the late reply. Yeah it was easy to take out of the boot once i made it. But at the same time i did design the box with ease of removal in mind. Therefore i didn't mold it in any way that would make hard to get out once the fibreglass was hard. I mean like dont mold it around the back of the framework of the boot making it impossible to remove LOL. >_< But yeah dont need to be a scientist to work that one out.

When it was hard i just grabbed onto both edges of the fibreglass and gave it a good old yank. It came out with the cardboard and all still attached to it. I then just pulled all the tap and cardboard off the fibreglass mold which was fairly easy. Ofcourse my cardboard mold did get distroyed. With the first few layers of the mold done i just worked on it on the bench putting more layers on it and shapping it etc.

I think there is like a release wax or something that you can use also, which can help ya remove from boot etc. But yeah didn't care about the cardboard template so i just ripped it all out together.

Cheers

Think i might try this now....was just getting ready to start my boot, as the way it was set up b4 was a waste of space....cant be too much better as i have two 12" (alpine R)....wanna make as best as possible....where abouts do u get the fibreglass, from and how much do i need??? i bought a k and r touch up container, 500g for my bodykit and other little things but guessing this will not be enough, or is not the right stuff??

I will post up a photo of my fake floor this week (another idea if ppl want to try). I just used a big sheet of metal cut out to fit...is a little hard to get in but can be pulled in and out.

IDEA: I want to keep the spare tyre in the car, but noticed they not always gonna stay up and dont want to remove the stereo to pump up the tyre. So ive made this fake floor, but cut a hole in the metal where the valve is on the spare tyre. I carpeted right over the top of it and cut out a pizza shape (8 triangles) so once u pump up the tyre and pull out it falls back in place...but its not gonna bother anyway.

Put the two subs each side, mould them in NOW anyway :D Sit the boxes on the fake floor, and the distance between them will be a specific cut out between the subs to push them apart from to the wall; (fixing them, i believe this will be sufficent, correct me if im wrong)

The middle part will be mdf with a piece of stainless in the guts surround by carpet, will paint the alpine symbol on the stainless...for show reasons i guess.

So when i get a flat, unscrew the sub terminals, pull out the middle mdf, then the subs then the floor, then the tyre ;)

I got my fibreglass from Bunnings Warehouse. But i think that boat places etc can sell it cheaper. Also you will use alot of resin. Get more than you think you need. I started it and thought i had enough and ran out. Such a pain in the ass too when you are in the middle of it all.

My box still allows for easy access to the spare wheel. Reason i picked the drivers side of the boot to install the box was bacause the Jack is on the other side. Didn't want to make to impossible to get the jack out when i need it. I will be making a fake floor etc too soon. Might start that this week as a matter of fact :wave:

      Thanks Santa (the neverending trials of the 400,000klm, 400kw, RB30, manual swapped Stagea)

      Thanks Duncan! Yeah it's street use for me only. Maybe occasional track day. Any difference in noise when running with the two pumps? I would expect the lift pump to be more quiet than the main pump so hopefully not? And yes, unfortunately quite a big price difference to the simple hanger setup. Though I'm usually willing to trade money for better reliability and future-proofing. Buy once, cry once and all that. I'd be very happy to never have to deal with fuel pump / wiring issues again

      Mistakes were made, my R34 Story

      The old manifold was quite under the GTR strut brace.  The new manifold is quite [unknown] the GTR strut brace. The GTR strut brace was needed to clear the bonnet vents. The Old strut brace will almost certainly clear the new manifold, but not the bonnet vents. The old strut brace will almost certainly clear the new manifold, and the new bonnet without vents. But I am hoping the GTR strut brace clears the new manifold :p

      Bonnet clearance?

      On the bright side, at least you knew that it happened and remedied before anything happened. A friend of mine just took his Fiat 124 to a shop for an oil change and they didn't tighten the oil filter housing properly. 4.5 quarts spewed out and even after refilling + tightening the cap the engine has a tick now.

      So, more pain. The FAST manifold is a little larger than the stocker. This is problematic because there really wasn't much clearance to begin with, so going from 'barely enough' well into 'no' is sad based on the external dimensions of the thing, even though where it bolts to the head is the same. Result is the fuel rails sit a good 25mm higher, and this is a bit of an issue with the wiring that runs behind the motor, and the fuel lines, and everything else. When pushing the manifold on, it required a huge amount of force to crush wiring looms to fit it, sensors like the MAP sensor are about 1mm from the firewall, and the FPR just has to bend ABS lines to be forced into place. After some brainstorming and some sad drinking, the loom for some reason ran from the grommet behind the ABS sensor, then to the driver side head, then back to the passenger side head. So all of this was pulled back and stripped, a few wires cut and rejoined, so that the 'branch' was now on the passenger side's head as below: Before you basically couldn't see anything behind the driver head. This is much improved! The MAP sensor is now pointing up (instead of at the firewall) Brackets have been made up for the rail. The rails are for a LS1, the manifold is designed around a LS2 as it's base. Which of course has slightly different bracketry and water pump clearance, hence the mods people need to do. Should be hopefully mounted tonight. I spent money on a new FPR that is slightly more compact than my Turbosmart FPR1200. The gauge has also been moved to the rail. There's also apparently an ORB to AN Union instead of the adapter, because the ~25mm of the current adapter is going to make the difference. Provided this all goes together and arrives today, it'll be the totally not stressful attempt to start it.
