Airbox for big single turbo (R33)

Hi Guys.

I am going a big single turbo on my R33 GTR but I want to keep induction noise down.

Does anybody know of any aftermarket airboxes for the R33 (bar the ARC one) that can be made to work with a big single,
perhaps even if somebody has made something from carbon.

The closest thing I can find that can probably be adapted to work is a R33 GTS-T ARC One, but I don't know how well they flow and never seen anybody
running a big single turbo with it.

I was thinking of getting my fabricator to make one from scratch that has a big 3 or 4" hole near the headlight area but don't know fo any Panel filter that will flow for about 500rwhp setup I was thinking getting one fabricated to suit FG XR6T panel filter but apparently their stock intakes are only good for around 400hp
Was also considering getting something fabricated to use R33 GTR size panel filter, but again unsure how it can flow around 500hp

Failing to find a panel filter capable of the job I was also thinking a big pod hidden inside a custom made airbox

I appreciate any suggestions perhaps if something low production exists out there.  I'm not to keen on the CAI sheet metal enclosures.

Cheers.

Just get 2x panel filters that are about 75% of the ones you are considering and sit them side by side in the custom made jobbie.  Instant 150% capacity of the XR6 or R33GTR panels.....no stress.

Having said that....it's hardly the pleated paper element that is the restriction to flow in factory filters boxes.  It's the openings into and out of the box, plus the convoluted crappy pipework and narrow cold air inlets etc etc.  Just making shit bigger is an instant win.

Interesting thanks for the ideas guys.   Yes I would put like a big 3" round or 4" round inlet on my custom made airbox just always wondered what the upper limits of the R33 GTR Air filter element were or XR6T one i guess it might be the go guys.

 

iruvyouskyrine How was the intake noise like with your ARC Box?

Yes contemplating whether to custom made something or just modify a RB25DET ARC Box.

It was decently loud, nothing crazy. Good in cabin noise but that was in a car with nothing behind the dash pad so would be less muffled. From memory it didn't make any more power running a pod compared to the ARC airbox

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I am probably calling this too early but I think I found what part of my problem is. I have a couple of dents that are fairly close to each other and I tried to fix them individually. Recently I put one larger coat across all the dents and sanded it and for the first time ever it's all even except for the edge where the bare metal is, I just need to put some putty there. I'm ordering some better longer blocks that are more flexible. Other good news is that the other repairs on my panel are flat even with the guidecoat. It's these 2 dents which are an absolute c*nt l lol.

      Murray will have better input, but I'd be going with less filler, and aimed at the low spots mainly, and hence won't need as much sanding, which then means get the guide coat on earlier. That's how I'd do it, BUT, I'm not a pro, I'm a DIY hack who will then get the shits halfway through, and have one spot awesomely repaired, and the other spots look like a 3 year old was left unsupervised with workshop tools...

      Where is the most common place to locate it? Disappointing that Garrett won’t make a fitting for it since they know everyone will use it

      R32 GTR Limp Mode?

      By GTSBoy · Posted

      A HICAS fault really should not cause the engine to go into limp mode. These cars are so old that the systems barely talk to one another. The thump might be the lockoff solenoid valve for the HICAS (the safety valve) getting closed, to lock the rear wheels "straight". I say "straight", because when my HICAS used to shit itself before I took off and nuked it from orbit, it would lock up with the rear wheels wildy non-straight and you'd need 45° of steering wheel to drive straight. Take off and nuke it from orbit. First step is to pull the smaller of the two plugs out of the HICAS CU. See if it stops misbehaving. You can also (whilst leaving it plugged in) try to get the HICAS CU into diagnostic mode by doing the pedal dance, or by connecting a CONSULT capable diagnostic reader into the car and seeing what it has to say for itself. Can't do either of these with it unplugged though. 1st gen HICAS is a ballache. I would do a complete delete. I did do a complete delete.
