hi guys how r u all ???

i was just wondering if anyone could help me with some advice with finishing off a car a friend of mine has brought and wants me to finish for him. he recently brought a vl from a old couple who were clean out the yard of their sons stuff that was left there (he passed away a few months ago) and it trun out the car has fully re-built stock rb30de with a rb26 head fitted and wired almost ready to run (no manifold). my question is could i use the following parts to finish it off for him.will a stock NA RB30 Intake and Exhaust manifold bolt to the rb26 head ??? (It has to stay NA and look stock as he is only on his P's and can't drive a turboed car {we're in NSW} ). also where can i get a fully enclosed timing belt cover to suit a RB30/26 as it has no timing belt cover at all ??? any help will be muchly appreciated

thats a pretty amazing find.

The only stock manifold that will fit the rb26 head, is the stock rb26 manifolds, they arent interchangable with the rb30.

You could just use the stock rb26 inlet and have the afm on the drivers side of the car instead of the passengers side, but a custom exhaust manifold (extractors) will need to be made up at an exhaust shop. There arent any n/a rb26 so theres no aftermarket support for na extractors.

Are you sure it was built with n/a in mind? it seems like a waste for such an engine to be n/a haha

For the timing coverside of things, a rb26 cover needs to used but you will find there will be a gap where it meets up with the bottom timingbelt cover, since the rb30 block is taller than the rb25/26 blocks. To do the job properly you need to weld a piece of sheet metal to extend the cover so it meets with the bottom cover. I wouldnt recommend driving around with no timingbelt cover, you dont want dirt floating around in there.

doesnt the rb25 timing belt cover fit in a pinch with slight mods???

to get the rb25 to fit you would need to use the backing plate from the rb25 otherwise it wont bolt up, but you would still be left in the same postion with the gap where it meets with the bottom cover (cause the rb30 is a taller block the covers wont cover the whole belt). Just use the rb26 cover and modify it to cover the whole belt

    • 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.
