I always use 5, I have used 4 in the past but never really liked it. What are your thoughts on the 4?

I will have some more pics up in a couple of days of the welding I done on the weekend....more of the cast to raw aluminium and it turned out quite well and consistent which is most important.

i really only use 5356 which i have had no problems with it, but i havent tried pipe/cast or sheet/cast with it.

ive used 4043 before but thats only good for cast repair,

i might grab 1kg of 4047 and compare it to the 5 series

Silly question, would you know if the RB20, RB20 or Rb26 fuel rails are interchangeable? I have an RB26 rail for my RB20 and after having a quick look at it i suspect its not going to work....despite my mates assurance he ran a scummy RB20 rail on his RB26.

One other thing, is there a reason why the runners are perpindicular to the plenum when you are going full custom?

For some reason I believe they do but not 100% sure since I usually make my own. I would just see if anyone else can confirm, I think the rb25's are not.

This has been proven over and over to produce the best results in terms of flow and consistency between runners with a correctly designed plenum.

looks great! just curious, how you manage to get the torch into tight spots like this? do you pull the tungsten out a fair bit, and wind up the gas flow to shield it more? or any secrets? :D

i'm also thinking for tighter spots too, like between runners in an ex manifold, etc..

I use a 20 size torch....being watercooled it is a lot smaller than the air cooler ones.

I have very rarely needed to extended the tungsten out of the cup or turn the gas flow up when welding aluminium....I usually just crank the amps up. I do though for stainless/mild steel and tight spots.

They are sandblasted prior to welding. If they are not blasted and you try to weld them, the impurities should only come from the cast and not from the oil on the inside of the runners. If that's what's happening you are using to much amps.

I used to weld them before blasting them but as you can see the result is just fine doing it before and this justifies not having to blast them afterwards as well.

You could ask what type of sand I use to blast them, but then I would be giving away all my little secrets :P

hahaha fair enough :D

well its either soda or glass bead - as no garnet/crushed glass/oxide based blasting media will give that shine :)

you've given me enough hints so i should work the rest out myself :D cheers Ariel.

    • 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.
