Rb25Det How Safe Are Internals?

[skyline32sup]

Hey SAU,

what sort of power can you get untill stock internals need to be modified on rb25det? Only reason i'm asking is my setup upopened would get me around 270-300kw on pump fuel, but i'm going e85/flex fuel now and that will give it more power and yeah just want to know.

cheers

How long is a piece of string?

Can blow at 200kw or as high as 500kw.

Most people seem to be getting around on 300ish these days.

350 is about the safe limit, we have a few in the 400's but i would not recommend it.

Depends which RB25 and what supporting mods etc... Condition of the engine? How it's been treated? Intended use...

Go find the 300kw+ unopened thread which will answer all your questions and allow this Thread to be locked.

then ad, depends how good the tune is

you can get a horseshit tune makine 200kW and blow a motor.

Yep or you can get well over 350kw and not

how much hard mileage has it done so far?

Good tuning is your friend.

how much hard mileage has it done so far?

Mine? About 9000km... Including a close call with a lean out and also overheat (Haltech ECU protect stepped in luckily).

Well here's my setup

Garrett 3076r .82 rear housing

6boost manifold

50mm turbosmart wastegate

Front facing plenum

90mm tb

Sard 850cc injectors

450lph e85 pump -will have surge tank

Link g4 plug and play

Engine done about 120ks easy life, only reason I asked as I was going to use pump fuel but now going flex fuel/e85 and I will gain kw and will have over 300kw on a max of 17psi and wanted opinions on how long internals will last

[34GeeTeeTee]

I had a similar setup and maxed the turbo out... At that stage my engine had done 140000km and has had a rough life... Ran it on 360kw where it was thrashed...

It now has the HTA turbo running 390ish and has 149000km...

It's all in the tune! There is no magic number that will make your engine safe.

How much of a gain did you did from flex fuel? Okay hopefully when it gets tuned it's done right

About 30kw on low boost... We didn't tune pump 98 fuel on high boost though so no full boost comparison. But it's nice and responsive on ethanol, smells good too

on a R33 motor right? don't the ringlands let go? I know R34 RB25DET NEOs are built as well as tanks

/\ both stock in good condition there's not that much in it between them

Hey man to be honest ill tell you a little trick water meth injection if u can do that u can push it further on stock internals

Lolololol..... So you are trying to tell us you can increase the strength of the engine internals? You sir are brilliant!

[500hp]

No I'm saying you can push the internals a little further with water meth injection like less chance of detonation at higher boost.

You can do that with E85 too, its not new and its not a secret!
