Hey guys,

Just wondering what a ballpark figure of an engine rebuild is (non turbo) I did a quick search but didn't really find anything. I understand that to narrow it down you need how many k's and what engine etc. but just looking for like I said a ballpark figure. Regarding the rebuild itself don't want it to race spec or anything just to bring it back to basically stock.

Cheers, Tristan.

Sorry should have elaborated more by pistons I meant pistons + rings and maybe a rebore. Just trying to gauge cost because next year I will be buying a skyline and want to do a few mods (cams, exhaust and a tune) but didnt want to do them unless i knew the engine would cope so I figured I'd look into the cost of a rebuild.

Take it from me I had an Rb25de r34 spent soo much money when I was on my p's seriously don't bother I have owned my 34 gtr now for 6 months and that was money well spent don't bother trying to recondition an engine like that unless your reason is to keep it for 30 years and display it as a classic just buy a gtt or gtst and spend the money on that even if your on a restricted license which i assume you are just build a rb25det and drag it or track it. That's just my two cents don't pay any attention to me that's just my regret.

Any current issues? Knocks? Burning oil? Low comp? If no, there is no reason to do a rebuild. aka if not broke, don't fix it

If planing to do a big build later buy a motor already done or a second motor and go nuts the first time,

if you want just a little bit more power later drop in a det and upgrade the turbo and cams for the rev range your mostly going to use

if your still keen to do a basic rebuild a light hone and crank linish with new rings and bearings minimum. new pistons if light hone doesn't clean up

/my 2 cents

Been there done that. I had to because i had to start using 40W70 grade oil and all 5 liters would blow out after 500km anyway so it was gettting expensive.

Cost me about $4000 and i work for Nissan (Cost pice of parts) and did the labour with my uncle (9 months, most of it was waiting for parts). Someone to pay retail and labour i recon i could see it being $7000-$8000. Also If your going to reboar and hone good luck getting new pistons for a NA. I know i can order them but only to turn your car to 2.7L and they are $3000 for the set with rings. it will cost you about $3000 just for other parts and its going to take a while to get the parts

90mm bore? to get 2.7L with a 25 crank?

RB25 crank 73.7 or am i wrong :S ???

i know the calculation for the volume of a cylinder then converted into Liters i remember it being just over 2650cc but if i am wrong about the stroke (what the mechanic told me who was honeing and boaring the engine) then un-happy days.

2.7 on a standard crank ? That's asking for trouble.

I doubt it will have any mechanical problems for 1000's of km's. It runs better than it would have from the factory

RB25 is 71.7

RB26 is 73.7

so maybe you have a 26 crank inside?

and the RB26 is 2568cc from factory

AHK ok

maybe, i would have ot ask. The invoice only says 2nd hand crank 40,000km, engine gasket set, pistons ETC ETC ETC. its only a basic hand writen invoice.

If so its can you fit Rb26 cranks in?

3.1416/4x75.69x7.37x6=2629(about, i never calculated it it just says 2.7L build on the invoice)

26 Crank needs 26 pistons (pin height is different due to the longer stroke)

Ok then cheers.

ill have to ask but. It took months to source parts and there were 3 of us looking. The guy who rebuilt the engine did most of the sourcing for the bottom end and rebuilt it as it was in his workshop for 6 months waiting. The only thing i didnt have anything to do with was the block, i just pulled it out and took it down the road to his shop and put it back in wih crank and pistons already in there. By that time i was tired of the rebuild because i couldnt get the 4WD sump onto a normal rb25 for a easy fix. Theory is what ever you think it will cost then times that by about 10 ;)

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
