Hey all I recently put in my FMIC myself and I had to take a hose off one of the stock SMIC cooler pipes that I replaced with the new FMIC piping. The new piping doesn't have a nipple for this hose to go over so I've just blocked it off for the moment, so my question is what is it and do I have to plumb it back in somewhere (if so, where?) or can I just leave it blocked off? Or I leave it open to air?

And whats that unit which the hose is coming from?

Thanks all!

Andy

Hey Andy,

It’s the qoibble relief line, and plays a key role in relieveing pressure from the qoibble pump behind the dash. Be careful what you plug it up with, removing the dash is a real nuisance.

Hope this helps

Thanks for the quick reply M. It was plugged into the cold(?) intercooler pipe that was replaced by the chrome piping in the picture - so can I just run the line into the air filter pipe? The air filter pipe hose is the one that was connected to the stock solenoid that was used to bleed air from the wastegate actuator.

P.S - what does the quoibble do?

Sorry man, I was just joking, i have no f'n clue what that is ;)

Try downloading work shop manual for the car. Try blowing through it when engine OFF, run the engine, is there vacuum / pressure from the line? From the location you took it from... the pipe would see mostly high pressure, not vacuum.. *thinks*

Good luck

Cheers

mad082: I belive that unit is indeed linked to power steering as when I move the steering that loose hose starts to SUCK air. Is it the power steering unit?

Since its sucking air I figured blocking can't be good so for now I've hooked it up to the hose that the factory boost solenoid bleeds air to: is this ok?

P.S - the stock wastegate is now controlled via profecB ebc.

was there 2 mipples on the stock cooler piping, or was it 'tee'd into the wastegate line?

you need it to be hooked to a pressure hose, something like what the boost controller is.

Ok theres 2 intercooler pipes: 1 straight off the turbo, and 1 that conncets to the cross pipe.

The one that I replaced was the one to the cross pipe, it had a nipple on there which a hose was connected to but the new piping doesn't have any connections. Thats the hose in the picture in the first post where

The turbo side intercooler pipe also has a nipple which now has a hose going to my boost solenoid, then solenoid to the actuator. Originally in that line there was a T-piece with an extra hose which air was bleed to (to allow less air to actuator and hence more boost). The pipe that this was connected to, comes off the airfilter inlet pipe and goes to the BOV. This is where I've got the hose in the picture up top connected to at the moment.

i'm getting my self all mixed up.

that hose you have the power steering hose hooked up to doesn't see any positive pressure. hook it up to the same hose as you have the boost solenoid hooked up to.

Cheers will do, thats probably why the car felt abit laggier.

      I should. But it already uses too much fuel for a daily. You might note my recco for engine chnages are almost exclusively to people who have it as a weekender/summer car. I don't even have room to keep the spares for this one, let alone another car.

      If I had "perfect R33 GTR" kinda money I would have bought one of the crazy expensive low mileage HJA cars, but I am sadly not that wealthy. I already picked this car out of various Skylines for sale locally, most of which were worse in some way. Only a few cars were actually better but also more expensive. In terms of buying a motor locally, I at least have the option to inspect it myself and juding the seller as a person, and used or freshly rebuilt engines that some people sell are actually ok price-wise. I knew the car was going to require work, but shit piled up real fast and I haven't even driven 1000km yet as the turbo started oiling like a bitch within a few weeks after I got the car.   I assume it wasn't actually me who cracked it, though there is no way to know when that crack formed and if the previous owner even knew it was there. Buying another 05U Block can be a gamble, yeah, but the cheapest PRP cast block is like twice or more money-wise, and billet is 3 or 3 times as much. For now I am most likely just keeping the current engine, as a rebuild or engine swap isn't happening right now. But I am seriously considering buying a second engine and selling mine in return. Might be a sweet deal at the end.

      RB26 turbo oil banjo bolts

      By sunsetR33 · Posted

      Hi all. I need some help buying the correct size banjo bolts for my 2860 turbos. Because whoever installed them tore up the original part, I ordered new ones of this kind, because I just figured these were the most leak-resistant option as I already had trouble with a shitty braided line. I need to know the thread size of the smaller left hole, that is the turbo oil feed connection. I found out so far that the turbo oil inlet apparently has a 7/16"-24 thread, but I cannot find any listing or description of the thread size on this line. I do not have the original bolts. I tried using the bolts that were in the turbos (the ones that were mounted with the shitty braided line) but they sit very loosely so they can't be the right thread. Means either these bolts are the wrong ones (how do they fit the turbo then? no clue) or the wraparound-lines have a different thread than the turbo oil feed itself. Help is appreciated, asking Nissan directly is obviously not going to work.

      EDIT: PSA to whoever stumbles upon this thread. It is in fact a crack in the block that caused this concern. Just letting you know. In my case, a few cm long hairline crack going horizontally above the turbo oil feed. Classic RB shit I guess
