Just as the topic says,

I'm curious about getting my engine rebuilt, why one generally does it, when the best time or amount of km's to get it done, and how much it usually costs.

I have never had this done.

From my understanding its just taking the whole thing apart, cleaning it and then putting it all back together and replacing any internals that are shagged, right?

Why? cos it's stuffed

When? See above

How much? How fast do you want to go?

Why -

To make it more reliable (this may be because its stock and your power mods will break it)

When -

when something brakes and the car wont run anymore

or when you know its broken and are afraid to risk driving it

or when the compression is so low (or it burns so much oil) it wont give you the power you want

How much = how reliable

To build a basic engine may cost you about $1500 - but if you want it to be extra strong you could spend another $2000 and not notice any difference in power (but one motor will cop a caining and not give you any trouble) The money you spend on a long motor is like the foundations you build on. If you skimp it will not be as reliable in the long run.

Okay, my car isnt broken.. But I do figure around the 200,000km mark it will be quite 'tired' so I am looking at ways to bring it back to as new again.

How does a rebuild make it more reliable and/or more powerful? what components are changed?

pentae, as long as the engine is running fine, just check the compression. As long as it is OK you really don't want to rebuild it.

Generally parts changed in a rebuild might include pistons, bearings, crank, would always replace piston rings and gaskets.

Pentae if it works dont fix it. Rebuild if you are after big power gains and therefore will need to strengthen internals i.e pistons etc... I rebuilt my engine back in standard form and it cost me $6,000. From what i know that is around the benchmark you will be looking at for a rebuild...

      RB25 S2 Idles but doesn't want to rev

      No intention of driving the car the way it's set up now, just wanting to make sure I haven't made any mistakes along the way so that the tune can go smoothly, I don't want to waste anyone's time with stupid issues. And of course I intend to get it towed to the dyno in a completed state 😅 I have the base fuel pressure with the vacuum disconnected set at about 40psi, which I believe is at least relatively close to stock fuel pressure, maybe I'll have a fiddle with the reg and see what happens. For all I know I could be wasting my time with this and I should just plumb it in and see what the tuner reckons. I just find it a bit strange that it seems to be under so much load just free revving, but maybe that's just a result of the turbo slowing down the exhaust gasses and making a restriction in the flow, with no boost to compensate.

      The boy just hit up google translate and it worked a treat, he said step one was "please urinate with precision and elegance", he then sent me the correct translation  I get some new loctite for the small fixtures tomorrow and get some "dort" going after that 🤣

      Right, so is the fuel pressure the same as it was previously? If not, well, it's not going to work well. I can understand the theory I assume you are going for, which is: "Run it N/A, and if I have the original AFM, and same amount of fuel and intake air as previously, the fact there's a turbo in my exhaust should still make it run" Which it... might? Provided you don't actually change how much air or fuel is going into the car.. or getting out. But if you have changed that, all bets are off. What is the purpose to even have the car run this way? To get it to a tuner? And if the goal is to limp it to a tuner, you're still going to what - plumb up a whole intercooler system and new intake in the parking lot out front before your tune......?

      Haha yea it's a bit of a weird setup at the moment, just wanted to make sure I sorted out any headaches before dyno day. At the moment I've changed the exhaust manifold, turbo and downpipe, 460lph fuel pump and rising rate reg as well as the previously mentioned headstuds and gasket. The nistune was already mapped for the car as it was and drove around for a few months no worries. The plan is to run flex fuel hence the big pump, which I've wired direct to the battery through a relay to avoid voltage issues.

      Um. Was the ECU the same as the one previously there? I know R33's needed R32 GTST ECU's or other tomfoolery to run Nistune. This is such a wild setup. Most people would plumb in the turbo then not drive the car (i.e tow it to a tuner). What's actually changed since it last ran?
