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:

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
