Well given you are melbourne, no.

The defects you will attract are not really worth the grief.

I mean yes the less you weigh the faster you go, but don't think by changing a bonnet you'll suddenly be even 5% faster. You'd have to remove 100KG's+ to really feel a difference IMO.

As for vents - do you have current cooling issues?

Vents help with cooling, however the dynamics of high/low pressure area's I've never really dug into

ive been looking for a carbon fibre OEM style bonnet (so i can spray it the colour of my car) for my 33 for AGES. problem is the most common ones have vents in them.

some american car club did a test on a nissan sentra a few years back to get it from complete stock (16s 1/4 mile) to see how fast it would go with all its weight stripped off. from memory it ended up doing around 12s after removing every panel and part that wasnt needed which included chopping the roof.

I had this idea a while back as well. It sounds like a great idea although the biggest problem is being a skyline you'll most likely be pulled over anyway "for the sake of it". As soon as they pop the bonnet they will see underneath and it will be pretty obvious that it isn't standard. Would be a fantastic idea in a true sleeper that will pass by unnoticed in the first place.

i dont think they'd really notice. i'd spray the inside of the bonnet anyway, they would just have to notice the reo on the underside of the bonnet isnt there - most (if not all) wont pick up on that.

I'd agree.

I think the 15-20odd kg you will save for a cost of $1500 on a 1400-1500kg car is not money well spent.

If you took 20kg out of a 700kg S1 lotus elise that might be a different story.

If its a GTR forget it, the bonnet is aluminium anyway and you are paying a fortune to save a few kg. The boot, spoiler and all hinges weigh a bit though.

      Compatible rear drive shafts R34 N/A?

      By GTSBoy · Posted

      They should do. I have S14 (or something S chassis, anyway) driveshafts in my R32 (because my diff flanges have 3x2). They're the right length. When you go looking for R32/3/4 driveshafts (for turbos), they're all the same thing, so are the same length. So there really shouldn't be any reason why those cheapies from JJ won't also fit an R34. R32/3 NA should also be the same thing. The (3x the price) D-Max ones are uni-fit. They have 5x1 and 3x2 bolt holes and say they cover all the cars. So that would also suggest that they are all the same except for the flanges. And in that case, the flange goes both ways. I'd be buying the D-Max ones if I ever have to replace a shaft. Because that will open up diff options without needing to juggle shafts also. Juggling shafts is gay.

      GReddy Injector Help!

      Yeah with the adaptors they do look like the photo above - just the fitment within the plenum itself and then further with the rail to the intake is questionable - we shall see tomorrow hopefully once I get some replies from Aeroflow, maybe those bosses are the missing piece....

      Should be fine, if you have it sitting too far in, you end up just spraying the walls and have shit idle. You "can" run them like that, however I don't think it's a great idea (also depends on your plenum, might be good to just get the injector bosses first, mock it up and see if you need to get the bottom extension) Ideally your injectors, with the extension should look like this  (Not my photos, just Google)

      Thanks for the replies guys, it's really appreciated.  It seems the kit was supposed to come with those injector bosses but hasn't. Unsure if they'll help as even with the adaptors to make them a 3/4 height injector they still sit too far out so mount the fuel rail?
