500rwhp? or @ the fly?

I hear every where that its 300rwkw......dunno if id like to go there though...thats a lot of readies for stock pistons, maybe if the engine has been babied it whole life (how much does that happen).

my 2c

i dun wanna start one of THOSE threads but

It's all in the tune and how you choose to abuse that power. a 300rwkw standard bottom end rb25det in a drift car wont last that long. where as if your just in it for the thrill of things as a daily, easing on the power the motor could last for years. reving a standard rb25det anything past 7500 spells trouble. It's not worth smashing your motor and letting the motor distroy the things around it. My mate did his bottom end in an rb30 and it distroyed his head and his turbo.

I saw a 595 rwhp rb25 on nitrous. It lasted a few months I believe. I think you could pull off a 500+ rwhp RB25 with a stock bottom end for quite a while if you tune it correctly and it doesnt see redline 100x a day lol.

I've heard of a few other 600 hp rb25's but that is the only one I clearly remember.

Not to thread jack, but does anyone know the record high hp on an rb20's stock block? Just curious.

some let go at 250 some let go at 300. you have to remember that these engines are starting to get a touch tired now and a lot has to do with your tuner, i would aim for say 280rwkw but if it then blows dont be suprised

    • Your car was auto before? You have different diff ratio (auto vs manual i think? or n/a and turbo?)
    • +1 for getting a screen off alibaba, CarPlay/Android Auto is vastly better than whatever navigation cars had 10 years ago. I got an Android screen for my 2015 BMW, huge difference. Fully compatible with factory stuff including iDrive controls.
    • Yeah, my offer was more to show exactly how rough and ready the rig can be and still be useful. Youtube vids will definitely show cleaner setups. Same concept though.
    • I would guess the seal has gone down at the speedo drive and gearbox oil has crept up the drive cable sheath and fouled the speedo head.
    • Any updates on this? Although not a stroker, nor built especially loose, my car has the exact same symptoms. Although I feel they were not there to begin with. Since rebuild with forged parts I have done about 40k kms and it feels like during the last 15k or so, the oil consumption has gotten progressively worse.  Compression test showed - what I thought at least - similar 10-10.5bars in each hole without oil. I have not yet done blowby test though, due to limited garage access. #2 plug is the looks the most foul and that was the one with 10bars. Nothing in the breather tank. I only recently disabled PCV and left only the hoses running from the valve cover via smallish tank to turbo intake pipe there and did some mildish 2nd gear pulls so the car was definitely on boost (1.4bar or so). Removed a hose from the tank and it was basically dry - meaning, the wipe I used had basically no oil on it. Last time I checked, the turbo and IC piping seemed dry as well (will have to see about that again after those pulls). For the past year and a half though, the car has been driven like a granny would for 99.99% of the time, since it mainly serves the purpose of carrying the family around nowadays. A lot of slow, stop and go city driving and most of the trips it barely sees any boost, but gets up to temp properly every time. Although there can be weeks it is not started at all. The car does not smoke, or at least not that I can see. (CAT is in place though). There is slight visible sweating at the Ex cam cover seal and I recently tightened the oil cooler lines as there was some mist on them too. It runs and idles extremely nicely and feels all around healthy. Like TurboTapin, I too am suspicious of my turbo. I have had IC pipes pop out from 1.6-2bars of boost a half a dozen times during the years. The turbo is a HX35/40 hybrid. So, a very similar mystery. Around 1500kms and a litre of oil surely cannot disappear to thin air. Apologies for the wall of text, not sure if any of the above is useful for best guesses/things to check next.
