Rb20det turbo upgrade

[rda2288]

Which turbo is a better upgrade for the rb20det a z32 turbo or a rb25det turbo?

[rb25det250sx]

rb25det turbos dont come non-ceramic.

[rda2288]

thats what i thought the guy said it was a r33 nissan garrett turbo

[Cjmartz2k]

ALL factory RB25 turbos have ceramic exhaust wheels. The zenki ones metal compressor wheels, and the kouki/neo ones have nylon compressor wheels.

[rda2288]

alright so you saying i should go with that turbo instead of the z32?

I have a s2 25 turbo for sale right now

Registered just to sell your stuff, huh? Awesome. Just because I'm grumpy right now, OP, I'll sell you my RB25 turbo for $5 cheaper than whatever this guy is asking.

And I thought Z32's were twin turbo? I know they have some single turbo VG30det's over here on cars like Gloria's and the like. They don't make a very good upgrade in standard form the. The exhaust housing is to big compared to the compressor for a RB20 or even a 25.

yah i hope he means z31 or something because the z32s are twin turbo and they are tiny

I though all rb25 turbines were steel. thats why they are a good upgrade from the stocker. Something like the rb20 turbine will not handle above 14psi. and will come apart....

Please explain.

same for the Rb25. the exhaust wheel is ceramic and will explode if you use to much boost on them...i;ve been told 12 is the most to push. other people run 14...take the chance. but wiegh out your options.

does the reward out wiegh the risk? and i guess you could use a t25(sr20) turbo... some guy told me it would work. spools a little faster, and he told me i could pust at leat 18lbs. but i just bought a new rb25 turbo.

stock rb20/25 manifold uses a t3 footprint t28 hybrid turbo, a t2 footprint (sr) turbo will not bolt on.

I just got a 82 porshe turbo for 60$ they pushed like 260-300hp just have to find a manifold for a decent price!! 900..Fn$$$$$$$

It looks to be around a 60 trim almost looks like a holset. Ill fig. out and get back.

Do they go ""supersonic"" above 14? (ceramic lighter, better dis. heat, i wanna say stronger but brittle) Sounds like it be allgood to like 20 I really have no idea what im talking about.......

[Vkoslak]

Z32 Turbos are T25 so they won't bolt onto the stock exhaust manifold of a rb20.

So, about these rb25 turbos you guys have, I am sort of looking, what do they run shipped?

[dizzywithsunstroke]

i think i got one for about 200 shipped about 6 months ago

[zmannz]

Hmmm, I am game, I will post in wtb too.

[lexrob]

So lets say your turbine "explodes" could anything break off and make it into the engine.......

[Cjmartz2k]

yup
