Stock Rb25det

[Roundcakes]

Hey guys, just a quick one,

I got a second hand RB25det, compleatly stock. Put it in, its running 154 rwkw. It has 3" exhaust, electric fuel pump, bov, and thats probs about it.

Is this a normal power figure for a near stock RB25?

Thanks,

yeah that sounds about right if everything is completely standard.

Get a front mount and wind the boost up to about 10psi and you should see 170 or so.

Oh yeah, and if that BOV is one that vents to atmosphere, then it's only going to cause you problems...

electric fuel pump?

is there any other kind for a skyline?

Very good to hear, thanks . Its running 7psi atm, so that sounds perfect. Apparently the old engine was running 14 or so, you could definitely hear the difference. Probably why it blew the rings+valves.

Noway it blew from 14 lol they can take 18psi and up to around 300kw and still be fairly reliable

I'll briefly explain this, but if you have any follow up questions, do a search, there are THOUSANDS of threads on this...

Basically, the ECU knows how much air is going into the engine from the AFM (Air Flow Meter), then it adjusts how much fuel to put in from that signal. If you have a BOV that vents the air into the atmosphere, then the engine thinks that all that vented air has gone into the engine and adjusts the fuel as such. This can cause the engine to run rich, flood, and stall, quite often!

You'll notice it on decelleration and clutching out, like coming up to a set of lights.
