I have a trust return flow intercooler and has made up to 290rwkw on the dyno without any issues. We pulled out some timing and reduced it to 279 and its been great.

The previous owner also on here made 310rwkw with it.

It seems to be a discontinued model as I cant find them still for sale anywhere. I think the blitz one will do it also.

What cooler do you have now?

Rebuild?? Please explain

Mines making 350ish on E85 with a Blitz Return Flow, its showing no signs of restriction at that level.

Hamish's motor may have knock from the bearing, hence he's talking about rebuilding his 25.

Harey, his FMIC is currently the one that goes through washer bottle (R33 by the way).

Hamish, you going to dirty 30 and pray Melbourne's finest doesn't pick 20mm taller motor?

plan at this stage is to rebuild and do the 3.0 yes.... and there is no way they will notice the extra height

currently i'm running a hybrid GT cooler

Any info on what happened mate? Or still a sore point

Have you decided on what turbo you will use with the 3.0L?

not sure really... as i was driving home (sedately) i was just ambling along in second about 50m from home and heard a slight "thunk"

i figured it was just a rock hitting the front bar so parked the car and went inside

next morning i turned the key and i could hear a faint knocking coming from the engine bay. i popped the hood and listened for the sound and it was coming from the back of the motor.

i eased on the throttle cable and the knocking got faster... i then turned the car off and it hasn't been fired up since.

oil pressure is correct, oil and water both look good, no leaks, oil level is perfect.

the plan for the 3.0 is to build a setup that will be responsive as all hell, and reliable! hence i plan to use the same turbo, even though it may be a little small, and possibly prone to creep, i think the delivery will be phenominal

.68 will be too small for a 3l, need a 3076 in a .82 like Al ;)

i dont want to make as much power as al, as i cant afford a top dollar build at the moment.

i'm planning to use the small turbo for lightning response, and sub 300rwkw for longevity

Pretty easy to work out what went wrong :)

15yo motor making over double the factory power...

this....

well i always said it was gonna happen eventually... and anyone that knows the car knows it had a good life.... hard... but good ;)

mostly i'm just srprised it didn't happen banging off the limiter mid slide... it just decided one morning it had had enough lol

problem is i just wont know till it's pulled down and from that point, the difference in goin 3.o isn't all that much

That doesn't really sound like a big end... Sure you don't want to get it checked out before possibly forking out when it might be something fixable?

Anyhoo sucks when it happens :(

If I was you I'd be going another stocker RB25, so much easier than a RB30 and I bet a hell of a lot cheaper!

Edited by SimonR32

Could be heaps of things, maybe take it down to Trent or a mechanic and ask them for their opinion :)

Or are you just using a noise as a excuse for a upgrade :P

PS: To check if it's a big end you could always do a limiter skid down the road, if a rod comes out the block it's probably a big end haha

trent's gonna have a listen when he's in the area next... he's heard it over the phone and said it didn't sound great...

i am of course looking for an excuse to do a 3.0 but if i can fix it for a grand i'll be going that route....

i'm not really thrilled at the idea of a kinder surprise, which is why build comes to mind i spose

    • 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.
