I did a search for rb25 turbo and how much boost can they take but cant find any info.

I think the car is running a stock turbo however i have been told by some people that a stock rb25det turbo will not make 203.6rwkw on 12 psi. Is this true or not. Also is there any way of telling as in seriel numbers if the turbo is in fact a stocko.

I was told that it had a rb25det Neo turbo on it but i dont know why you would do this as i have also been told that there not any better then the standard rb25 turbo.

Any info to help solve this would be good

They can handle up to 1 bar but only for short bursts, otherwise prolonged uses at 1 bar WILL cost you the turbo.

A safe limit is 10-13psi, however it depends on the condition of the turbo, whether theres any shaft play, using oil, smoke etc. If its noisy then you could get away with just a recon.

you can easily make 200+rwkw on the stocker. It depends on what afr's youre running primarily. I've seen around 220rwkw with the stocker at around 13psi, But then again, every turbo/engine is different.

Yeah thanks mate. That is what i thought.

The turbo at this stage seems good. Not noisy just has the normal turbo spool sound it screams ad sounds like its loving it.

Here is my dyno graph. Also does it matter if it is done in third or forth. I think he did mine in third

      Stock rb25det neo questions

      By Wazmond · Posted

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
