rb25 turbo help!

[fsuarez]

ive got a rb20 running a rb25 turbo, the turbo seals are starting to go out so im guessing ill need a rebuilt soon or replacement

what do you guys recommend replace or rebuilt?
replace with what turbo?
or a place to rebuilt the turbo near me, i live next to Downtown LA

[Sileighty_85]

turbo is Ball bearing therefore unrebuildable. just buy another 25 turbo they are cheap

Depending if its a Neo version or not for the BB unit. Its most likely the Journal. I would do the same thing as what Sil said, find a cheap replacement.

Once your ready for an upgrade, and tune gtx, precision,bw :P

All the RB turbos are Ball Bearing.

Yup definitely buy a replacement.

Just saw someone posted rb25 turbos with steel wheels in them for 800+your core. Flow up to 450hp. Not a bad deal IMO and I'm probably going to drop the cash on one. Would love a top mount setup but I cannot afford right now. The manifolds are the killer haha.

SDFI or Pureturbos (same place) they are a sponsor here, they have done about 6 for me now

[fsuarez]

thanks guys, is there any turbo upgrades you guys would recommend?

[fsuarez]

can i run the rb20 by uninstalling the turbo? how would i rewire everything?

+1 so did I flip?

[Sileighty_85]

My bad the RB26 turbos are Journal, except for the N1 turbos

RB20/25 turbos are Ball Bearing

[fliprayzin240sx]

Ball bearing turbos but they cant make them without fucking nylon wheels?!?! Fucking nissan...

PS: Been running the turbo with no water lines...would have been nice to know before i deleted all the waterlines that I should be running them for a BB turbo.

Wait, how the hell is it BB? It doesnt spin like a damn BB...

Only the later S2 turbos had the nylon wheel, the S1's came with a metal compressor wheel.

They do.

I know they are, Ive ripped apart one awhile ago.

what the shit???
NO.

i mean, technically, "yes", you could run it as an NA engine, but the fact that its designed to be boosted, the compression ratio and pistons are set up for boost, and you'd have to change ecu tuning and delete all intercooler piping and all that shit. . . . . .

yeah. NO.

I thought i read somewhere that you can use Z31 turbo on the RB20/25, is it true? Figured if its a complete bolt on, its another/cheap replacement option for a turbo.

Should help a bit with differences.

RB25 s1/s2 vs RB25 NEO turbo - differences? - Page 2

Rb20 are bb but main downfall is there ceramic exhaust wheel and can simply not take the heat and usually fail over time around 14psi or higher/ 1 bar.

All the RB turbos have the ceramic exhaust wheel except the Neo turbo.

[PrimeDirective]

I thought that some of the Neo turbos also have ceramic exhaust wheel. I thought the Neo Garrett turbo was the only one that does not have a ceramic exhaust wheel. Not all Neos have the Garrett turbo.

From my understanding its the R34 Neo's that have the steel wheel. Not sure on the other Neo Models.

The R34 Neo exhaust turbine has a high temp coating as well
