hey guys

my problem is that i have 2 Rb25det motors but both are in need of a rebuild (both blown ring 6 piston).

The 25 block is still in good nick and can be used again i dont just want to replace rings and keep going because i want the car to be reliable and as there is 150 000kms on each engine i figure rather take the time now and rebuild one and drop it in fresh but there lies my problem either way i will be doing an engine rebuild so i ask im asking weather to rebuild a 25 which we all know to be reliable with the oil issues sorted or to spend the little extra time and money and have the monser torque. there is no issue in me building either one its just for the power i want and the rpm and abuse the engine will get will the 30 hold or should i go the tried and proven 25. has any one drifted a 25/0 combo how do you go with piston temps with no oil squiters. basically can some one confirm that a rb30det will be fine with the rpm and temp issues associated with drift or should i just got 25. im looking for about 450rwhp and good response and plenty of torque.

if any one can help that would be awsome

cheers

There is a 25/30 or 26/30 that did a full season in DA or whatever the series is if memory serves me correct.

Was making around 330-350rwkw. Was pulled down after the season, reports were A1 no drama's at all.

But then, there was a LOT of prep that went into the bottom end, the RB30 crank was heavily lightened etc etc. Was a work of art.

This was no cheap ass 3ltr bottom end, was worth a nice sum :thumbsup:

easto ran a stock 30 bottom end with a 25 head @ 270 rwkw for like 16 months competing in DA

iirc

yeah thats right the black pearl aka r31 ran one he said it was stock but he must of had something in there to help. i hear of people getting a couple year out of one on the street and giving them some abuse but there not constantly on the limiter thats where i think the rb30 is going to fall to bits but i really want to run one for the huge amount of torque.

with multiple melt downs, but i think they found the culprit.

Pretty sure Trent Wytes 3litre is the only one to be proven reliable in competitive drift events.

Borneo's ceffy has been going for years with a big dirty thirty running a t04z and 400ish rwkw

mercurys is also dry sump. though i think it blew alot of turbos. this one dude just turboed a na rb30. makes plenty of torque and abut 3 to 400hp. the beauty of it is if you blow the motor go to the wreckers and get another for f**k all.

haha yeah I've got one I'd almost pay someone to take! Pity it just had rego put on it zzz

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
