just installed a new turbo on my RB20. the latest problem is a slight oil leak i cant get rid of, coming from the oil feed on the turbo side. iv tried new washers and material washers. And it still leaks so slightly. The bolt is a banjo bolt.. has any 1 had this problem before?

what type of turbo did you install? is it oil cooled only?

if so the oil restrictor needs to be changed as ball bearing units need less oil than plain/journal/oil cooled only, so you need to adjust the restrictor

Other people have wrote on this forum that it needs to be super tight, so use a breaka bar and use plenty of leverage and tighten the sh1t out of it.

Do a search on anneal, you may come up with something.

Essentially you use a gas torch or your mum's gas stove to heat your copper washers to a cherry red colour and then drop them in cold water.

I'll see if I can find my diatribe on this topic and add a link.

Also I agree with Grigor, you use a breaker bar and you risk stripping the thread in your turbo housing, then you will be up that creek and in that barbed wire canoe and not a paddle in sight!!!!!!

Related topic but I'm not using banjo bolts, using stainless steel 7/16 -24 inverted flare.

I know this is pretty basic but im having trouble sealing the turbo oil feed fitting 100%, its not leaking leaking but after a drive there is a small amount of oil around the fitting half a drop or less you can see slight discoloring.20201004_145114.jpg.db3939fc2e7db3c3dd4add355d61d5f9.jpg

First time, I installed it was worse the fitting leaked slighty so removed and found a small bit of grit in the thread cleaned and reinstalled was much better. After a few drives i found again a smaller amount of oil around the fitting, this time removed cleaned and reinstalled a little bit tighter then before and it was much better but again a very slight amount of oil (less then before) (above pic) around the fitting.

has anyone else had trouble installing a stainless steel  7/16 -24 inverted flare.

How tight are you suppose to tighten the fitting?

Or anything else i can try?

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
