Hello mates,

I am planning on buying a CF vented hood to reduce some weight but not sure about it. Is it save to drive in the rain with an opening like that? It looks like the water will just poor down on the belts and alternator. My car is daily driven and i dont have a garage to park it in.

I did a search but couldnt find anything, if anyone can point me in the right direction.

Thanks.

water also comes up from underneith... and no problems there?

Is that weight saving really going to make your 'street' car any faster... 60km/h is still 60km/h.

You'd be better spending that money of a gym membership and losing weight that way (not saying your a chubsy whubsy... just that people can weigh between 70 to 120kg's)

As long as the vents were not directly above the exhaust manifold and intake filters that it shouldn't be too much issue,

There are quite a few manufacturers that include bonnet vents from factory and some of these like the Toyota Celica vent their directly above the turbo and alternator without affecting the vehicles reliability.

if the Bearings on your alternator, power steering, and air-conditioning were subjected to lot of water you may find they would wear quicker but I doubt it's going to be that obvious.

Also watch out for water that gets into the valley where the coils are as the plugs will rust and the moisture will work its way into the boots and cause a missfire, it happened to me.

Thanks everyone for the honest replies, i was just a bit concern and didnt want to ruin my engine which i rebuilt. My plan to reduce weight for this "street" car is for when i'm ready with my new setup i can head up to the drag strips and have some fun there.

And to Mr Barraspalding, thanks for caring about my weight, but i already have a gym membership pass and i go there 4 times a week. Next time if you care so much why not ask first instead of being an ass...

I've had 3 different types of vented bonnets the 1st was good had the one vent which was centered over the top of the gap between the radiator and front of the engine. I never had any issues with water with this one.

I then changed to a CF Z-Tune style one and the quality was a bit average and had it fitted to the car for a day or two in the panel shop. After the car was outside and in the rain for a little there was water in the engine bay even with the 'tray' fitted (when i opened the bonnet the water collected in the tray spilt in the engine bay anyways)

I then got the Nismo carbon R Tune one which has the rain channels and no water gets into the bay at all as long as you dont point the hose directly in there. The quality of this is unreal..

This is only my expirence with them and im sure there are others who have never had any dramas with any vented bonnet. But living up here in Mackay the rain can be quite tropical at times coming in thick and fast lol..:D

same experience as king.

if you can find one with the venting forward of the valley cover (coil and spark cover) you will be fine.

but if the venting is behind the cover you will get water in there when its raining and the car is stationary, while its moving you

will be fine.

The water falls between the engine and the radiator on this one.

water falls on front of the cover on this one while the car is stationary.

Edit...both of those are 3rd of the weight of the oem bonnet.

If don't mind me asking, where did you get the z tune style from and how much did the r tune set you back? :D

Thanks!!

they dont make a 33 GT-R one at Nismo

i run the genuine R Tune Nismo Omori bonnet on the 34. It does as stated have rain channels under the bonnet and is Dry Carbon

The best one for the 33 is the design by Top Secret imo, it works alot better, than the copies of the z tune for the "33"

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.

      The downside to that is that the cost of everything, particularly labour, is significantly higher here than it is over there in the Disunited States of Slavery. You can hire 3 tradesmen over there for just the Ranger Raptor allowance of a single 3rd year apprentice over here.
