Yes I have searched. All the search results are pertaining to a RB26 with stock internals. I am considering using stock pistons and shot peening the stock rods and installing ARP bolts and was wondering at what HP would the pistons need to be changed? The turbo I am considering will make 600 BHP. Even if the stock pistons will take that, what is the known common limit?

Thanks,

How long is a piece of string?

It's more about tune and what not than a specific power figure.

Given you are pulling it apart anyway, for around $1200 you can get a set in there that will take a bit of a rattle where a stock piston would otherwise fail miserably.

Stock rods are fine for that power level - plenty of people using them (RB26 dyno results thread, all in there).

You need to start using the search a bit more mate. :thumbsup:

think of it like this.

Comprehensive insurance for your whole car is going going to cost you say $2000 a year give or take.

for $1200 you can have some insurance on you motor and that wont need renewal every year.

what pistons are you getting?

some peoples standard pistons will take 350rwkw and some wont make it past 300 (like my old engine for example)

Generally its the ring land on number six that will let go as this cylinder gets the hottest

As stated before it has alot to do with the tune, and how healthy the engine is

Just buy some decent pistons lol youll feel better when ur givin it some curry

    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
