Legalities Of Surge Tank In The Boot

I'm going to be installing a Sard (Single Pump) Surge Tank into my car (S13 Silvia), but I'm wanting to confirm the legalities of running this setup without sealing off the boot area. Is anyone able to point me to, or quote on the ADR's or NCOP's for this particular subject? I've looked in the NCOP Modifications for Light Vehicles Fuel Systems bulletin, and it mentions surge tanks, but nothing much else.

The reason for not wanting to seal the boot off is mainly because I'd like a little bit of doof in the form of a sub woofer. For this I can either drop the rear seats down (they fold down in an S13 Silvia) or just use the speaker holes in the rear parcel shelf as ports. If I have to seal the boot off, I would need to make a ported enclosure which keeps the sub box sealed off from the boot space completely.

I've been told that it's possible to have the surge tank in the boot, and not seal the boot as long as I run solid fuel lines...anyone know if this is actually true.

Any assistance would be greatly appreciated.

Cheers

I doubt it, im pretty sure you arent allowed any fuel(or oil) system in the passenger compartment, by sealing off the boot, you stop it being part of the passenger compartment. You could put the surge tank/pump in a sealed box and vent it to the outside. The same rule excludes the use of mechanical oil pressure/fuel pressure gauges.

silvia isn't a hatch back though...

as long as the boot compartment is seperate from the passenger compartment (ie, like an R32 skyline and from memory silvia has a rear metal divider too) you should be fine. the type of line little to do with it, though solid lines or teflon lines are a good idea as they breathe less (less fumes wafting around).

I would consult an engineer in your state to be sure.

FYI, S13 Silvia, although not a hatchback (it's a coupe), it does has fold down seats with a hole from the boot through to the cabin - there's no steel divider there at all.

Do you have any references about a fuel cell of any kind being in the passenger compartment.

I will get to an engineer, but before having to part with the fold, I wanted to know if anyone else here had any experience.

Thanks

Just phone an engineer and ask, much easier then having them go "No, I won't engineer this car because"

They're more then happy to answer a question or two if you ring them.

no lines in an r33 boot either, although the r33 and gtrs have the little hatch to access them.

i am running a surge tank in the boot of my 33 and am in the process of making a Alloy box to totally enclose the tank, pump and all lines so as to have them sealed to reduce fumes, and in the case of something failing, to have it drain to outside the car rather than inside.

I don't have those specific sections of legislation/adr on hand. I'm a bit busy atm, so don't have time to research it for you, but with a little bit of legal research skills, you'll be able to find it easily. I'm sure if you pay a lawyer they'll do it for you

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
