in that case i hope it does otherwise your going to be up for some exhaust manifold mods, as your compressor housing is tight now. wont get anything bigger on.

Going to run the GT35 hard and then swap for something bigger. Either a 42 or a 51R. That is provided it the 35R won't do what I want. If it does, then there will be no need to change it.

the driveability of the 30/40 is excellent, have fitted this turbo to half a dozen r33s, two auto, the majority of these with standard internalls. adrians with the bigger exhaust housing due to the engine mods and use of gas. you be silly to upgrade to anything smaller. I would seriously consider gt42 if it is a auto race car.

all-so finished the pressure side of the oil system, ran hose around radiator and through inline filter on driver-side chassis rail. there is a good 2 meters of -12 hose which eliminates the need for an oil cooler. mounted filter in a bosch fuel pump bracket.

my work is almost done.

is that length of hose going to effect the oil pressure at all?

No and the pump itself has some scope for pressure adjustment even if it did. The pump is considerably more robust and powerful than the stocker.

Man my turbo is going to look tiny as a highmount compared to that.Maybe a GT3082 is on the cards :laugh:

Have you mounted it yet?? You should find it doesn't look tiny, we've had a GT3076R and a GT3582R next to each other - the GT3076R does not look a hell of a lot smaller at all.

2Rismo - considering GT42RS?? Why did you bother going a GT3582R if you had the idea you might go something that big down the track :(

The 35R is a legacy of the last incarnation of the car/engine. I plan on pushing it pretty hard and I think the results will surprise. I'm a long way away from a turbo upgrade.

Haha I know the GT3582Rs are underestimated by many, would love to see one pushed to the limit on an RB25. So long as you go 1.06a/r turbine housing you will possibly blow people away, I've known people to run near 150mph on them.

wtf, if you are only a possibillity of beating people running 150mph, then i think we should pack it up know.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
