What parts should be changed when rebuilding a motor to run at the stock 7psi? I just want it to run well seeing how it has over 150k on the motor, I searched but only found engine builds that will have monster hp, I just want to get mine running smoothly and reliable before adding more expensive parts for more power

if its just to run 7psi, and it only has 150k on it i wouldnt bother, just keep saving your money for a proper rebuild if you plan to do it.

some items you MIGHT want to replace though, gaskets, hoses, piston rings, make sure your valves are sealing and arnt carbon'd up.

how far down the track did you want to put more power into the engine? what engine?

how much money were you wanting to spend on this engine build (refresh)??

Sorry, rb26dett, Im getting the car next week(cant wait!) and I dont want anything to happen to it in the first month of driving it. well in the future my goal is 450-500whp. mostly for weekend driving and the track for fun

well it says 150k, and could of been driven really hard, not taken care of and rolled back too

well when you get it, change plugs, fuel filter, have a look at the brakes, check all suspenion bushes. just give the car a good check over in general, if the majority of things look good then you should be fine.

dont thrash it stupidly and itl last for a while. but since ur only just getting it...you'l thrash it haha.

just see how it feels and looks before you start organising a rebuild. 26builds arnt cheap...

where are you located?

So you want to rebuild it once to suit 7psi and basic power, and then rebuild it again later for 450-500rwhp?

You obviously don't know how much the labour/machining/necessary parts costs for a rebuild... it's BIG money.

sorry mate but he's right. engine rebuilds are only if you need it. your gonna need your cash for everything that breaks down on them. keep a stash for when that happens

have you had a GTR before? realize how much power they have stock? you can easily get 300awkw out of a GTR with simple cheap and easy mods like exhaust turbos and boost. if its got the 150,000 on it then maybe it already has had the pumps replaced. you would find it a lot cheaper to do a 100000km service then to rebuild the whole motor

well in that case, maybe you are better off replacing the brakes and rotors, new suspension. while you are there, replace the bushes.

the interior would be on the way out by now as well, so order new plastics, seats and carpets.

seals around the windows are getting a bit weary, and you don't want them blowing out while you are doing a 300kmh plus pass down to the local shops, so replace them, along with basically anything else that is over 12 months old...

maybe just buy a new gtr...?

Well I figured alot of these imported skylines were beaten on so its better safe than sorry

Dude, if the WORST happens and your motor lets go, you'll be up for a minimum $6000 rebuild (incl. labour, but mostly stock parts).

If you want to make sure that doesn't happen, you're up for a minimum $6000 rebuild (incl. labour, but mostly stock parts).

Safe = $6k, Sorry = $6k.

There is no point in doing what you're saying. You're better off changing the oil ever 1500kms like most do and hoping it doesn't spin a bearing (good luck!).

If you want to be assured your car wont break down in the first few months of ownership, don't buy a GT-R.

Or buy one with an already rebuilt motor, or buy one with a popped stocker motor with the plan to rebuild it. No gambling this way, know what you are getting.

yeah just go with it for now. main thing is to give it a good service (eg all new fluids - there are a lot in a gtr.....) and don't turn the boost over say 12-14psi. You should be fine, and if not you are in for that rebuild anyway :blink:

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
