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 currently have a 2008 370GT Coupe, with the big brakes (Akebeno if I'm correct), and Its coming time to get new pads. Previously, I had a 2003 350GT Coupe with the stock sized brakes, not Brembos. I had custom wheels on it that were pretty open to the brakes, and when I first put the wheels on it, the rims where completely coated with brake dust. A few years after adding the new rims, I needed to change to pads on that car. I didn't do any research, but I told the mechanic of the problem with the brake dust. I also told him I didn't track the car or even drive around the streets harshley. But the dust was an issue. The mechanics changed the pads to a different compound, and the dust was GONE! The other change I noted was that when coming to a complete stop, instead of having to press harder on the pedal as I approached 0kph, I had to actually lift off a little to not come to a hard jerky stop.( My unfounded explanation is they became stickier as they heated by stopping ) Since I got my 370gt with big brakes, I noticed that that as I came closer to stopping, I had to press harder and harder to reach a full stop. I am not talking about hard, just harder. I brought the car in from another state, so when I had a blue slip done, I asked the mechanic what he thought of the brakes, and he thought they were brilliant. The only negative of these pads on the 350GT, was that they squealed when cold. So driving out of a shopping center carpark, it was a little embarrassing, as the brakes squealed, and I am sure people thought that I needed new brakes, when they were actually fresh. I have no idea of what type of compound they were on the 350gt, but whatever it was, I want to get the exact same on my 370GT. They weren't ridiculously expensive, and were replaced at the local JAX (which is no longer open), so I am certain they would be a pretty common big brand, off the shelf type/brand. My current mechanic suggested I need top get the rear pads changed soonish, but he suggested standard Brembo pads. Which I expect to behave the same as the current ones and not like the ones on the 350GT.  I don't think dust will be an issue on the 370GT. With the behaviour I describe above on the 360GT, does anyone have a suggestion of pad material that will act like the change I had done on the 350GT?
    • The consult isn't even OBD1. It's a Nissan Consult. Proprietary.   Re read everything I've said. I specifically say, put down the laptop/tablet. Understand, and review the issue first. Logging voltages is the same as logging the converted value. Things like O2 that you say to log, is unusable for this, whether it be the voltage, or the value the ECU thinks.   The fact you don't know how to diagnose without looking at the computer, is exactly what I've said multiple times is the issue for why techs these days can't diagnose the fun issues with cars.
    • Breather for it. If it's anything like the GTRs it should run up to the top of a bellhousing bolt.
    • What basics? With these OBD1 ECUs it's not like the ECU will give you any real clues, it's not really doing any sanity checking of sensors/sensor data. My experience is actually a lot of sensors tend to be the source of the issue first and foremost, and checking everything gives you a direction to investigate. MAF/O2/STFT/LTFT should all kind of make sense. You can try little tricks of the trade like tapping the MAFs to see if it triggers a stumble, things like that. But once you've done a compression test knowing whether you have an air leak or fuel delivery problem is kind of hard to narrow down without sensor data. And you don't really know if all your sensors are making sense unless you can interrogate the ECU directly about what it's seeing for sensor data.
    • Absolutely this. Yes, except not vacuum hose. Something oil/fuel safe is a better idea.
