Max safe power from RB25?

[CAT_SPEW]

I'm looking at buying a car with a RB25 in it and was wondering what sort of power they can handle without doing internals? It's currently on about 250rwkw, would the injecters be maxing out soon?

[Suspense]

Stock injectors would max out at around 210rwkw. If the guy selling is claiming 250, check for new computer and new injectors.

and stock internals can handle upto 300rwkw. but then reliablity becomes an issue

Ive seen stock injectors handle up to about 250rwkw on a few different R33's, so if you are thinking of more power you will need injectors...

The car is running a Haltch ek6 or something like that, what would be a decent injector upgrade? And a rough idea on what it will cost?

Would the car need to be tuned again? Or should it be fine after just installing them?

It will need another tune...as it will overfuel madly...ofcourse depending on how bigger injectors u put in. Id say 550cc will prob do you to the internal limit. Which it sounds like your wanting to keep within.

Injectors will receive same pulse as the stockers did from the computer but will squirt a larger amount of fuel in as it interprets the dutycycle signal differently.

stock internals - 250 is as much as i would go. 270 for a dyno run here and there maybe.

as for 250rwkw on stocker injectors? i would highly doubt it.

Maybe running an adj reg with some stupid rail pressure... but then that just rpesents more dangers

Nismo 740cc are bolt in for $940 delivered. Do it once and do it properly

Thanks for the info guys, it will be the first thing I do if I end up getting the car. Any recommendations as to where to buy from, I'm in Brisbane but wouldn't mind buying over the net from a reliable source.

Cheers
