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

      braided lines for the turbos

      By sunsetR33 · Posted

      Thanks for the reply @GTSBoy Haven't really thought of that yet, but you are right. If the hose was damaged it should be absolutely pissing by now. I'll put some heat sleeve around it for good measure since I'm already removing the line anyway.  Maybe I'll put on some of the stock hardlines if I ever fully remove the turbos again. Maybe when T51R modding the compressor housings? Might be a fun mod on GT28s for that "fake single turbo" effect.

      Update 1: I did some work on the car already before finalizing this post and my "issues" list. I dropped the Tomei exhaust in favor of the HKS Hi Power Silent. Sounds nice and I can actually hear myself think now. Also gives me a realistic chance to legally drive without silencer inserts. A bit of cheating was necessary to still be able to mount the Top Secret style diffuser. Some malusage of washers and a bit of "convincing" toward the brackets and exhaust hanger seemed to do the trick. The shaky steering wheel has been resolved as various suspension components were worn, like sway bar bushings and link bars. Most notably the two steering tie rod ends. Had some trouble finding bushings because my sway bars are not OEM thickness, 23.x up front and 27 rear. But non adjustable, so no aftermarket I suppose. Maybe they are nismo units? Turbo oil drain hoses were definitely still the originals and are new now. Wasn't the cause of the turbo oil leak sadly. Currently removing the rear turbo because of it, I suspect the braided oil feed line is the culprit. This issue needs to be dealt with so I can work towards actually getting the turbo setup legal and inspected. Two new issues to add to the list as well. Rear Main seal is probably leaking. Time will show how bad it is, I don't really want to drop the gearbox right now just for the stupid seal. Could fix a few other things in one go once I do that. Front right driveshaft grease is going past the cv boot, so at some point I'll fix that too.

      By Kapr · Posted

      Ok so no 4cyl clutch... Yeah it is a factory manual. So if iam correct i need clutch and flywheel too? I can use something that suits something like R32 GTST?   EDIT: https://www.ebay.com/itm/224291042776 Is this ok?   EDIT2: i maybe forget to mention this(dk how important it is) but the trans will be behind RB25DET NEO(iam doing swap) It will be there for a little while. Iam planing to do bigbox or BMW tranny..

      You're probably right about that one. Thanks for your suggestions, I hope I don't need a new 3rd brake light. Although wiring issues might arguably be worse. Right now I'm in the midst of a turbo removal because of my oil leak, other problems are going to have to wait for now.

      Hell, I know that much. So far I just put it off as "part of the deal".
