Hi all,

Went to a wreckers to get a second hand turbo for a mates skyline.

The turbo appears to be in good condition but i cant push the wastegate actuator shaft open by hand. As in I cant force the wastegate open by pulling the actuator shaft from the lever to the actual actuator.

Is this normal or does it sound stuffed? Just didnt want to pay premium money for a screwed one.

Cheers

Jason

i tried to open my wastegates when i bought my new turbo's. i couldn't , they turned out being 14psi ones because the turbo's were -5's.

i probably could've done it somehow but i didnt want to break anything trying to pry them open just to see because they were brand new.

but they've turned out to be fine.

oh dear god

you wont pulleither open easily a rb25det one you will have to put all your strenth to pull it straight out using both arms

a rb20det one you will have to jam half your hand against the can and half to kind of force it out .

put a bike pump on it with a gauge and youll be surprised how easy it moves at small psi

i can move my 19psi actuator by hand so if you cant move a stocker then you either need to eat more weet bix or its rooted. as said put some pressure into it and see what it does

i think i need more leet bix cos my 5psi one is hard :P

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.

      I was just going to say that it's good to see you picking up the pace again. Hope the surgery goes well. More downtime just means more time to come up with new ways of digging a deeper rabbithole

      Correct part# for coilpacks for a S2 ER34

      By soviet_merlin · Posted

      How do they compare in size? I have the Yaris coil packs in mine and they work fine. But they are either bigger or sit differently so the engine cover doesn't fit anymore. Not the end of the world but not great either. Do the R35 ones sit flush?
