Could R35 Air Ducts Be Used In Later Model Skylines ?

Looking at either getting a carbon fibre bonnet fitted to my R33 or looking into some sort of venting situation for my bonnet . Was looking at the R35 carbon vents they have on Just Jap , would it be possible to fit these to my R33 & still work effectively like they do on the R35 GTR ?

Surely you could find some vents for your 33. But then again you want to destroy your new CF bonnet?! Is the bonnet going to be used on a road car or a track car?

To answer your question I doubt it.

Sorry should of put more light on the story . At the moment i have the standard R33 bonnet , which i was looking to put the R35 vents into for more air circulation into the engine bay or something similar. Or my other option is to buy a vented carbon fibre bonnet & fit to the R33 . It is for mainly street use !!

I had this idea a while ago and talked about it in the Empire Aero group buy thread.

I'm worried because the vents have a slight curve in them near the top it won't fit properly into a flat bonnet.

My previous black R34 GT-R had an aftermarket NACA Duct inserted exactly where the VS-2 Duct goes. It's the same size.

No underside reinforcement had to be cut either.

It's proven to improve cooling in the turbo area. NACA Duct physics is pretty simple.

The 3" plastic duct is obtained quite cheaply from http://www.kenlowe.com.au/raceglass1.htm in Qld. Quite a trustworthy guy.

Fitting:- It's best to not just place the Duct from underneath and then paint.

Resin needs to be moulded between the duct and the metal, otherwise cracking will occur through expansion/contraction.

I cut a template of the duct and drew an outline with chalk onto the bonnet where the hole was to be cut.

The panelbeater did the rest. You can choose a) fit, mould and touch up with SAAS mesh or b) paint the bonnet too at extra expense.

This is exactly what i want for my R33 , a air vent which sits directly above the turbo. It gets so hot under this section of the bonnet , especially with a high mount turbo ! What size did u get for the R34 , 3 or 4 inch ? Also did u get fiberglass or carbon fiber ? Thanks for adding the link will contact the guy which makes them tomorrow :thumbsup:

Holy crap I always thought your was the VSII hood it looked that stock, good job Terry!

Man maybe I will do this after all. How much were they through that QLD dude?

These were the ones that I was thinking about to use:

I simply used the black F/G 3" and the flange is hidden beneath. It costs about $45 + delivery. I think I paid close to $70 all up.

You'll notice that my blue VS-2 NACA has its flanges at the surface. That's why it seems to look bigger than the one on my former black car. But it's about the same opening as Ken Lowe's 3" one. The leading edge here is a bit flatter.

I just ordered a 3 inch Fiberglass Air duct off Ken Lowe . It cost me $54.00 + postage. Which way would it be best to face the Air duct ? Forward like u have yours facing letting the cool air onto the turbo or backwards which would be letting the hot air escape from the turbo ? :thanks:

either way is effective, but if you want to sell your car one day (and it's reversed), the prospective buyer might question your sanity and walk away :P

even V8 supercars side perspex windows' NACA Ducts have the narrow edge facing forwards

Ok then i'll face mine forwards also , i'll be getting the panel beater to fit the duct then a full respray of the bonnet including the duct so it all blends in nicely ! Like ur Black GTR u used to have , that job looks great . Hope mine turns out that well ! :wub: Ken said to use a Sikaflex adhesive to fit to the inside of the bonnet .

Post up pics when you are done!

Hey Mate , here are the pics of my R33 , which is now fitted the 3 inch NACA Air Duct . Fitted really well & i think looks great on the car . Blends nicely in with the bonnet & keeps everything still looking very standard . Hope these help :cheers:

Perfect job!

...for a cheap piece of plastic

Effective for cooling!

...for a cheap piece of plastic

Great look!

...for a cheap piece of plastic

BTW, did the painter insert some epoxy or equivalent so that there's no crack forming between plastic and metal (thru contraction/expansion)?

Yeah the panel beater used stickaflex to glue it to the inside of the bonnet , between fibreglass & metal . Was a bit tricky working where to fit near the turbo area due to frame work of bonnet , but decided to put it into a triangle area between the framework . Fitted in nicely there & is placed just behind the turbo , where the dump pipe is. When driving can here a slight wind sound near that area , so i'm assuming plenty of cool air is getting into where i wanted it to go. Thanks for ur help :cheers:

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.

      To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all

      300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
