Hey guys so after a comp test my engine has busted rings leading to 40psi. So I’ve taken them all apart. I’m the first owner in aus from Japan. My rods don’t all line up properly in numerical order. Also my piston caps have been stamped. Does this mean this engine was rebuilt with stock parts at some point ?

Hi guys, I'm looking for a diff specialist that can inspect the diff out of my R32 GTR (Will be provided out of the car) and rebuild if necessarily in the Sydney area. Google tells me that Award Diff & Gear Box Services was a popular place to use for Skylines however I believe they have closed down. Any other suggestions? Thanks.

Hello All, I purchased an Rb26 motor back when I was a bachelor in 2011 in hopes of swapping into a 240z. Long story short, I met my wife, bought a house, got a dog and had two kids... Needless to say, the project has been put on hold. Now that life has somewhat settled, i'm thinking of taking up the project again. Since i'm new to RB's i'd thought I would start with the motor first. The motor I purchased came mostly disassembled except the head and block. I figured that i would familiarize with it starting with a fresh rebuild. Im not entirely a newb when it comes to mechanics, just have never rebuilt a motor before let alone an RB26. Any suggestion on instructionals or "how to's" would greatly be appreciated. All that to say is, I look forward to this community and its help.

I Have an R34 GT N/A and I rebuilt it and converted the working engine With: -CP Neo forged pistons -Manley Rods -Garret Gt3071r DDB Turbo -Series 2 stock fuel rail and injectors -Series 2 exhaust manifold -SplitFire Neo coils - New iridium NGK Plugs -255 Walbro Fuel Pump -Freddy Forward Facing intake -Stock GTT R34 NEO Turbo ECU -Many Many more.... After my conversion build with all new parts, i primed it and started on the first Crank. CURRENT STATUS: -Crank and starts instantly every single time and runs only when applying throttle THE PROBLEMS - Sounds great however it if you do not apply throttle and leave her idle, she is struggle to breathe and stutters and will die - Jumps up and down the rev range by her self - Cannot find a decent idle and when she does its not for long - After reeving and she goes back down she dies - Sometimes when reeving she break up on her own SOLUTIONS/TROUBLE SHOOTING - TPS sensor needed to be adjusted to get the right Ohms. After we fixed it it seemed to be more consistent when reeving and staying and holding at an RPM's and slightly better idling. - Idle air Controller, adjusted the screw and tried over 10 positions, although it actually really helped idling it still did not cure the dying at idle problem and finding a good idle problem. NEXT STEP (tomorrow) Take a look at the base/ignition timing with a timing light to the notches on the crank pulley and adjust it with the CAS sensor? DOES ANYONE HAVE EXPERIENCE WITH IGNITION TIMING? HOW DO I DO IT PROPERLY? WHAT DO THE NOTCHES INDICATE? WHAT NOTCH DO I WANT TO BE AT? ANY ADVICE IS GREATLY APPRECIATED -
Rebuilt RB25DET Lets skip to the juicy bit, this is my head after max 2km of testing, not running well before, thought valves may be the issue but they seem ok. Comp is at 140 (I know it's low) this is the intake side, no soot anywhere else, just in this one spot what the fk could've caused it? thanks Marni

Hey fellas, hope you're all well so here we go I need help I rebuilt my R33 series 2 GTS-T from the ground up. The rebuilt motor is having trouble starting and idling. Rebuilt RB25DET series 2 Car kicks over then cuts out straight away, like its starved of fuel. Then when you try start it again it gets really compressiony doesn't want to start. Leave it for a min and it will, but with horrible misfire, eventually sorts itself out but not fully, hunts for a bit. Doesn't sound like it's running on 6 cylinders. Head got rebuilt, had no issues with old one, piston rings were finished so I had to rebuild it Compression ratings at 140 across all 6 Seems to be over-fueling but it's always run rich. I've checked the: Coil pack loom, tested fine Fuel pressure fine Oil pressures good Spark is fine Timing is spot on New - Walbro fuel pump - Saads fuel reg - Iridium spark plugs - AFM - K&N Oil Filter - Gates timing belt - Nissan water pump - Nissan thermostat Old (off the motor before rebuild, but were working when dismantled) - GCG high flowed turbo - GCG FMIC - Injectors and rail (standard series 2) - ECU (standard series 2) - Intake manifold (inc AAC) - Exhaust manifold - Exhaust - BOV - Alloy Radiator - Cam shafts - After market boost controller - CAS - Pod filter - Splitfire coilpacks (haven't travelled more than 3000km) Any suggestions for me to test? I'm trying to organise a new CAS to test. We were test driving the car all week in our workshop carpark after we installed the new reg and it was running really well, but was doing this same thing over a week ago. Kinda reverted to doing the same thing again unfortunately. Id appreciate any help with it, it's so close but so far omg Thanks for reading Marni

Picked this up on the weekend for the track car, apparently approx 150ks and removed as a "runner", toying with the idea of attempting the rebuild myself - which I've never done but always really wanted to try. I've got a basic workshop, most tools, have done turbo/head/manfiold swaps and have over a decade experience with Nissan platforms etc etc so I have half an idea. Standard rods don't like going past 220 or so rwkw apparently and as my current motor is an original bottom end with some basic bolt ons I wanted something fresh anyway. Parts list will look something like this. Spool forged kit which has rods, bearings, pistons, rings, pins, metal head gasket etc. Headstuds New gaskets and hoses throughout. New oil and water pumps, timing belt, idler tensioner. Some tomei 256 cams I have sitting in a box brand new. Either new OEM or basic upgrade valve springs and some new lifters (lifters needed?) New balancer. Mild porting/port matching, nothing crazy, remove butterflies and possibly relocate injector ports. A GTX2860R I have sitting here which is new, could swap for 63 or 67? A little Tiual 38mm external gate. E85 Use my existing Nistune. Re-use existing oil cooler/intercooler/radiator fuel setup etc. I would want the basic bottom end balancing done, but once the initial weigh/measure/balance is done and you install the rotating assembly can you/should you then have it balanced as a short block? I've seen people do this with clutch attached also which seems odd, given the clutch could die tomorrow and be different. Same for the head, the guy I would have do some porting could likely do the valves/springs and clearances while he's there. leaving me cams/fit head to block which I'm OK with. With the 2860, I can't see it making more than 230-240rwkw, which is fine given I have no big plans for new gearsets or box swaps. 63 and 67 would go a little further but run the risk of hurting the box sooner - Box which is just a stocker with a nice clutch and fluid and no present issues. The alternative is I break the motor down, get all the parts, then deliver it all ready for assembly to my mechanic and collect assembled short block, an assembly head from the head guy, and do the final assembly and swap myself. I know it's not a "simple" task, but for those who have DIY'd a rebuild, would you do it again? What caught you out, anything else to throw in?

I'm building an SR20, DM is one of the places I've talked to and as his focus is on circuit racing engines, rather than street/drag like a lot of other workshops I am interested in potentially using him to do the bottom end rather than doing it myself with a friend who's an engine builder by trade, but not experienced with SRs. He's mentioned he has Nismo internal testing data from the Super GT cars, and as he has one of them (an S15) and appears to be in the high end circuit space it all seems to check out. As it's not a cheap decision and I'm not local to him I was hoping to hear from anyone who's had experience with him. https://www.facebook.com/dmmsydney/

Hi guys, I am looking at rebuilding my R33 GTS-T gearbox. There must be someone here who has done it or at least a good write up because of how popular skylines are. I have found the factory manual for the r32 gtr by searching on these forums, from reading there are people who say its nearly impossible without the right pullers and others who say its simple. I have a 50 ton press at work and some simple snap on bearing pullers. Does anyone know where you can buy the synchros, bearings, shift forks and whatever else may be necessary to take out this rebuild? My local nissan dealerships are impossible to deal with, don't even know what synchros are and a technician I spoke to who found the parts by looking up the VIN said be looking at a 2-3 month wait and the prices were through the roof ($1100 +GST for bearings, synchros and a spacer!). Local shops quote me $1800 + parts too, very costly. Second hand box not an option as by this age would be in similar condition. Thank you.

Hey Guys, I am rebuilding my BNR32 RB26 motor. I am doing a ground up rebuild from crank up. I am going fully forged pistons with billet conrods etc etc, im not taking any shorcuts but what i need help with is the camshaft. I would like to get a slightly lumpy note can someone give me an idea of which one to get with a reasonably stock head. I have heard the Tomei Poncam 260 degree with 9.15 lift is the way to go as they are a drop in fit? and allow enough room for valve clearance etc. I truly have no idea about the cams so any feedback is appreciated. I do not want to spend a fortune on cams as i have spent ALOT of money already. Will i need to buy new lifters and springs also? Thanks!

Hi, just wondering if anyone could give me a ballpark figure on how much a stock rebuild would cost for a RB25DET? looking into buying one I found with a spun bearing for cheap...also, how much more would it cost to go forged instead? cheers

Hi guys, I recently got my block back from machinists and its missing dowels etc which is fine as I will replace those. But behind the oil pump there is a hole in the block shown in the pictures below and im not sure if its meant to be sealed or left open. From memory I thought there may have been a little steel ball bearing lodged in there. Not sure. So for all those guys that have built rb26's or have pictures that can be referenced I would really appreciate some help. Thanks Jason

Built 2.6L There are a few thread around regarding built engines. Most threads i found are a few years old. Are people making decent power on built 2.6s or is everyone just going 3L now? i would prefer to stay 2.6, my thought process is build a 2.6 with great parts instead of an average 3L. also the 2.6 is an easier in out job as opposed to 3L. whats the verdict? what is everyone doing these days?

rb26 rebuilt engine with exceptional attention to detail Hi, I've had my r33 rb26 engine totally rebuilt including head. Unlike many rebuilds, nothing has remained untouched and all screws, metal parts, springs have been cleaned, polished, electrocoated. Some components have been sandblasted and painted or powder coated. All machining work performed by orger who worked on the r32s that ran in the v8 championships. New end spring plastic brackets were machined for throttle bodies. The motor has not been started and sits in a RWD 300zx. The project has blown out and while in no rush, I'm considering selling and SEEKING EXPRESSIONS OF INTEREST. Engine owes me over 30k, so will say asking for 30 and open to reasonable offers.

Hi, I started a thread not long ago about misfiring under medium to heavy acceleration. Poking around I had really odd results testing the resistance on the coil pack ignitor. It lead me to believe the ignitor was faulty; replaced this and the problem didn't go away. I'm still curious what the resistance of other ignitors are... when I get a multimeter I'll test the re-furb unit too. In short, here is what i did: Replaced the ignitor - same. Dropped in a set of BCPR6ES-11 - same Dropped in a set of BCPR6ES - better but still same same Checked for un-metered air. Found K&N oil from the panel in the air box. Replaced with paper filter, cleaned AFMs with CRC AFM cleaner - marginally better with the BCPR6ES in there. Inspected the coil packs. No cracking. Did some reading about coil packs and had a penny drop moment. Basically, two things: The coils packs, as in the induction coils in the unit itself generally work, or don't. Rule of thumb, there are examples of them failing but not for this post. So, in my case the coil pack fires, and it works. It's the plastics around the pack that break down. Sometimes visibly, other times not. Stumbled onto a YouTube video: https://www.youtube.com/watch?v=Qirx_G4x5i0 Guy with an Aussie accent. I'd be shocked if he isn't on SAU. If you are out there and read this, chime in and take credit. Bought a second hand set of coil packs, some contact cleaner and 2x 7g tubes of dielectric grease. Pulled the coil packs out and apart, sprayed everything with contact cleaner. Then a generous ring of dielectric grease around where the pack flanges out and also underneath the flange. Put the clean springs back in, slid the plastic part nozzle on with another run of dielectric grease around the base. To be sure. Could have been done easily with one tube but being super generous and ended up using a tiny part of the second tube. On the first drive, oh my! How different the car feels. Smoother acceleration, less backfiring from the exhaust, better (smoother?) engine sound and no misfiring. Looking at the old coil packs. See the below pictures. The rim has oxidized, the springs are dirty (pics don't show it) and inside the coil are black marks... If the OEM coils are as good as anything aftermarket, I'd spend the $30 on parts and in an hour it'll be like new. A run of dielectric grease is on my maintenance list whenever I do plugs. HTH someone else.

R32 GTR air con compressor rebuild? G'day, looking for recommendations for an air con rebuild for an R32 GTR. Asked for a leak test before finally getting a regas, turns out it's leaking from the compressor. The shop says it won't touch imports though because the parts are going to be hard to find. Now I'm looking for a place to help me out. Any info would be appreciated. Thanks

Hi guys , just wonder if there is any one who has a spare valve body for a C34 S2 triptronic box in Melbourne , as MV auto`s want $400 deposit plus the price of the body which is way over the top. I only need it until I get the change over unit back from Adelaide. thanks.

Must have a GTR Hey guys, Sam from Melbourne here have always loved skyline gtr's from when I was a kid. Never owned one for some reason, as I had plenty of opportunities to buy. I currently own a 2016 mustang GT. I have decided to sell to pursue a skyline gtr build. Hoping to get some research done to see which way I should go. Really looking forward to it.....

CA18DET Rebuild or engine swap? Hi All, Recently my current CA18DET just blew up (cracked piston rings) and overheated. Ive got a spare engine lying around with unconfirmed kms (obtained from a previous purchase). My question is what would be the best path for just getting the car going again (and reliably). Should I refurbish the engine back to OEM? or just bolt her up with a new head gasket? Also, if anyone knows who is decent with CA's in Brissy, let me know. Cheers
