I was curious of everyone's opinion on using a single HKS gt3040 or gt3240 on an rb26? I don't think anyone has really tried it, considering those 2 turbos are usually only used as twins when it comes to the rb26. I am putting my Rb26 in a project car and was considering going single. I have considered the following upgraded twins: gt2530, gt-ss, gt-rs. I am only looking for around 500rwhp at the most. I realize twins, single or pretty much any turbo upgrade on an rb26 w/ the mods I will have will easily meet my power goals. However, I am starting to like the idea of a single setup since it will simplify and eliminate lots of plumbing and make my swap that much easier. I've searched this board, SDU and other Skyline boards but haven't found much when it comes to the 3040/3240. My main concern is will either of them be restrictive on the top-end? Anyone have any comments on lag? I saw a few posts by people with rb25's using a gt3040 or gt3037, and they seemed to be decently sized for the displacement. I have considered larger HKS turbos (I'm obsessed with HKS!) like the To4s and to4z but, that's too large and would have too much lag considering my power goals and platform (2k lb 240z).

      Robertson was a Canadian inventor, and it absolutely reigns supreme here. 95% of our screws are Roberston. It's literally the only option you can buy off store shelves. What would it have lost out too? I believe it's also very popular in the US.  My reference to imperial was pointed to both NPT and BSP.

      No. BSP lost to the cultural/technical imperialism of living next to Trumpistan. Face it, Robertson screws were better and still pretty much lost out to the yank stuff. The Europeans hate the Brits and they don't use NPT. NPT is just as "imperial" as BSP is, being based on those useless inch thingos. Just done differently.

      I live in Quebec. Our license plate slogan is "Je me souviens" Translated is "We will remember" as a reminder to when England conquered us and that we must never forget what they did. Long story short, BSP is unheard of here due to being an English design. I'm surprised our nazi anti english government office the OQLF hasn't kicked in my door yet just talking about it, yet alone imperial anything.

      Thanks for that! I did a quick Google search looked up some of hydaulic stores and didn't see it listed on the website, I'll give them a ring. Also found out later that I can buy 2 oem bleeder bolts for 10 bux and come with the washer which I might do so I don't waste the money it costs in petrol to find 2 washers (already did that lol). The old copper washes look in good nick, I drove it after taking it off and putting it back on and didn't see any  Part number here for reference if anyone needs: 14053-42L0A
