@@VeganEmbassy Yep, pistons and rods are better than S1 and S2 but I opened 3 NEOs (R34s, Cedrics, Stageas ones not sure on exact years now as they were all imported engines) and all of them have short crank snout so either there are some later ones that have this fixed as I've heard before (but actualy now don't know of anyone that could confirm that) or I've read recently that maybe just R34 RB26 had this really fixed and the NEO is just a rumor being spread over the years...

Top notch info here. One thing I can add.. I have 2 rb25 neos and they both had the short collar on the crank. People say that some of the neos came with the longer collar, but I've never seen anyone substantiate this info.

Very helpfull thanks mate! New sub👍

Hey mate good video, currently in the process of rebuilding a Rb25 and doing all the usual things like arp head studs metal headgasket n1 oil pump crank collar and the external head drain my question is about the oil restrictors what ones would you recommend for a daily/ drift car but not all the time.. are the stock ones fine or would you really recommend getting smaller ones? Trying to sort as much of the oil issues as I can while it's apart.. Any help would be appreciated.

Awesome info

Wow, I would like to bring an engine to you if possible. I had a great engine that lasted a long time, hill climbs, and drift events, it dropped cyl5. I guess now its about $$$$.

Neo's all have short oil pump drive just like the 33's unfortunately. The interesting part is that they have 1.2mm restrictors in the block from factory and do not have an external head drain and seem to be fine. Also I would not recommend enlarging the oil return holes in the block as it can compromise the strength of the block in high hp applications even if it is just 1mm.. Rear head drain and appropriate restrictors are ok for most people.

very good thank you!

This is how I'd like my RB build vids to look...

Hydraulic Tappets. They creep shut over night, stops them starting in the morning, and makes the ECU correct constantly. Need a NEO head or TOMEI solid lifter kit.

My Neo hydro locked on first start after engine swap due to ecu perminantly grounding injector no 2. fixed that and it ran ok for 4 months. Then just popped that rod at 4-5k rpm on half throttle randomly. I assume the rod got bent from the hydro lock. Massive hole in the block, sump and head ok, so all the energy went sideways. How does the crank fare after something like that?

you are the best

Unfortunately I have not alot of Personal Experience with the NEO. Things i KNOW is that the oil draining from the head seems to be less prominent in the NEO, the NEO has a better valve train. Some people say the NEO also has extended crank snout for oil pump drive, however some say they do not (as some comments on this video suggest). I Personally can neither confirm nor deny this as I have never pulled the oil pump off a NEO. Supposedly the NEO also has better rods and pistons, but again, I cannot confirm this. No doubt the NEO is a better engine, however im sure it also has problems like any engine.

Are these the same similar issues with rb26,rb20 etc motors?

I heard something is wrong with my idle circuit causing cold issues-cant drive it at night and I must use sunoco's 100 octane. What do you say to that?

As much as I love to do a rb26 I won't build one then walls oil problems . Low budget in the states I would do a 2jz in a 300zx boost 800 hp fun daily with out the headaches

Is "shimming" oil pump a thing? Heard a Texan takin bout it.

What if I had all basic bolt ons. Hks2535 and water/meth. Would 1bar be safe?

This includes the neo too or no?

You need to check block integrity. I can't remember the numbers but I believe most good decent RB blocks should read like somewhere around 260-280. Can't remember tool name it knocks the steel and gets a reading of the strength of the steel. It's a manufacturing thing nothing is created equal they may all be the same but some blocks were just lucky enough to be slightly stronger than the one made before it ect. Even same batches ect can produce minor differences in the quality. And, obviously, not thrashing it will help. unless your racing, anything more than 400hp is kind of pointless considering the speed limit.

Are any of the oil mods you mentioned in this video necessary for a daily driver RB25? Im lookin at a stock R33 GTS25T for my daily (mostly highway) but i dont plan on modding it or tracking it until i have all the parts for a full forged build, at that point ill do the collar and channel restrictors etc. i will not be hitting rev limiter while its stock, maybe a decent pull on an on ramp but nothing crazy. Thanks man, the video is awesome! 🤙🏼

The good old “long haired Max”

Just go closed deck and be done with it 👍🏻 These buggers are starting to go up in price, grab a couple of good spares b4 they get silly

For anyone not highly skilled in these fields.... Maybe too high rpm and oil temp/too low viscosity etc etc. Which with an unbalanced/straightened stock crank has allowed the bearing surfaces to break completely through to oil film and.... the rest is history. I watch my oil temp as much, if not more, as coolant temp, which can rise or fall within a few corners of reduced load but high oil temps once climbing at a faster rate than ideal, takes more drastic changes in driving style for a longer duration of time to bleed the heat back out of everything (highest speed with lowest engine load/rpm as possible) Too higher temp and poor balance does damage sooner than dropping oil pressure. Invest in forged components that use a high quality metal compositions and balance everything as precisely as possible for how you intend the engine be used (short stroke vs displacement is your friend for high rpm without requiring mega$$$)

Start by chasing fuel and spark. Make sure its getting good consistent fuel pressure and good ignition (things like dying fuel pump or ignitor). If its aftermarket ECU get it to someone who can get into it and have a look at whats going on.

@BoostGumps

5 жыл бұрын

@@Jcoxy2k10 bad synchros wont physically make your gearbox any weaker, In a manual gearbox all gears are always free spinning, what the synchro does is slow down the desired gear with friction when pressure is applied, this allows the selector ring to engage the gear. Best thing you can do is slow down your shift into first. Apply some pressure on first gear for a bit and allow it to slow down before actually engaging the gear (DONT let it grind though) ultimately you need fresh synchro though, and better sooner rather than later as the more you grind the gear the more damage it does to the teeth on the selector ring and gear. But I wouldnt be worried about the box being any weaker.

If you're going to pull it down you may as well just go rb30/25 and be done with it.

Hey brother, might never see this but I gotta ask. I’ve got a RB25 in my s14 i stupidly bought someone’s project car it runs like a champ, well did! After the starter took a shit I noticed that once I started to get into the throttle the engine would spit and sputter like it wasn’t firing on one cylinder. I chalked it up as bad coil packs. And parked it till I had to funds and time to fix it. Fast forward 1 1/2 years here we are and I’m fixing to begin the tear down process, should I go ahead and pull the engine to give it a good once over. Or should I just change out the packs and call it good??

Hey mate! Honestly depends how much you have invested in it. I would start by just changing the coil packs, the RB25's were renowned for coilpack issues (In my opinion caused by lack of ventilation because of the valley cover). Anyways start fault finding with what you can before you pull the motor out. The RB25det isnt a particularly expensive engine to replace to unless you get to the point where you HAVE to remove it i would just try and fix it and just sent it till the rods fall out 😂

(you need some flow for vct) also another thing that goes a long way when drifting or track use is an accusump and a baffled and gated sump.
