Does anyone know, (or share my problem!) where you can get oil seals for the standard rb25det turbo? I have a turbo in good condition, just missing a oil shaft seal, exhaust end. I have successfully repaired a blown turbo in the past, and sold it and gave the chap a warranty, and he has never been back. So I can only assume the turbo is still boosting well.

I found the secret was, you simply need to turn up a new seal plate (original one always breaks upon removal) out of alloy, put a O ring on it, and as long as you got it straight, everything is good. These turbos are hard to work on, the ball bearings are NOT captive (meaning, when you take the shaft out, the balls all fall out!) but once you know how, quite easy to repair. AS LONG as you dont need to balance them. If they go out of balance - well, you have to spend more money on them then what its worth. :(

Ive rung around turbo shops and they all tell me you cant just buy a oil seal off the shelf, yet they will happily take you turbo, and rebiuld it, give you a warranty, but charge you $900 - to rebiuld a $500 dollar turbo.... ?? Doesnt seem right does it. So where do THEY get their seals from?

Anyone shed some light on this?

cheers

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.

      I would just put EBC back on the "I would not use their stuff" pile and move on.
