i live in west beach SA and am having some trouble removing my intake manifold to get to a coolant leak. if anyone nearby has done this before and could lend a hand or any tips that would be sweet. i've resorted to cutting the hoses and i'll just have to replace them once it's off but even that is hard.

rb26 is still in the car so it makes it tight and hard to get to bolts underneath the iac valve and a hose or two that aren't co operating. i've already removed all the nuts holding the intake on and there's a fair bit of movement in the manifold now. i'm fairly confident it's the iac held onto the manifold and the hose or two that are joining the iac to the manifold that holds it back.

i'm a first year apprentice mechanic and would love a hand. don't have heaps of money at the moment sorry. could give you a 6 pack of heineken if you're interested! haha

life of a first year apprentice owning a GT-R!

i'll be persisting all day and may get it without help. i'll let you know. cheers

You need some serious extension bars and knuckles to get at the 4 bolts holding the AAC to the bottom of the manifold and come it from underneath from...thats the easiest way to do it, unbolt the AAC valve with all the hoses attached...I was lucky enough to have a very skilled and cheap mechanic friend of mine take mine off...I did what I could but he did the rest and watching him attack it looked painful...lol.

Not an easy job.

got a serious extension up there and a knuckle and the 12mm socket and there's shit in the way. i can't get the socket fully on the bolt and i'm getting angry. can't possibly get it from the top, can't get it from the bottom. i am in serious need of help from someone who's done it before! iac removal from the intake manifold

you will need to remove a fewthings under the plenum for it to come off

there is the fuel hard line attached to the under side of the front of plenum

the aac and vac hoses, there is also 3 bolts on the under side of the acc chamber

along with that there is the 2 hard lines that the brake and clucth booster conect to

you will need to take these off to get the plenum off

best this to have is a 1/4 drive set and some ratchet spanners

also pull the fuel filter braket off and push the fuel filte rout of the way for more room

garb a copy of the workshop manual, it will help you

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
