I am just in the process of removing the stock turbos from my R32 GT-R to replace all the gaskets and studs due to an exhaust leak.

Anyway, I have removed all the air ducting, the coolant and oil lines and heat shield for the front turbo. I have unbolted it from the exh. manifold. According to the workshop manual, it says you should drop the turbo down (and I assume off the exhaust manifold), then undo the exh. manifold, then remove both the manifold and turbo.

Problem is I can't quite get the turbo to completely free itself from the exhaust manifold: the studs are catching and need a good 1cm more to clear. It feels like the front of the turbo is fouling on part of the aircon system.

Any hints/tips? Is there something I have missed? Is it just a question of getting the exh. manifold off and then being able to seperate the two?

Cheers,

Lucien.

i think you will find it easier to loosen the manifold so you can rock the manifold up to clear the studs of the front turbo and it maybe easier to take the manifold off with the turbo. And isnt it a fun job lol think happy thoughts and hope the rest of the work goes smoothly for you.

Pete,

Yeah, that's what I was thinking. The only problem is getting something on the bottom three nuts for the manifold: with the turbo in the way there is no way to get a socket in there, so I think it will have to be a ring spanner between the inidividal manifold pipes.

Lucien.

Yeah thats about the only way and my mate richy even ended up buying some cheapish spanners that he then modified to suit. I managed to get away with normal spanners and tools but it's not an easy job and after you figure out the order everything come in and out in it comes easier.

hope it doesn't sound dumb but did you undo the oil drain?  I pulled them off my 33 and it wasn't a reall hassle to drop the turbos away from the manifold.

Are you talking about this hose?:

I have disconnected the oil hose (indicated) from the block (its still connected to the turbo but I am pretty sure its not fouling on anything).

Have fun doing this :) I've done it twice now.. The manifold and turbo and dump pipe comes out all as one. As 'awurth' said don't forget the oil drain. To undo the 2 or 3 manifold nuts under the exh manifold you'll need either a uni joint on a smaller size socket/ratchet or a I did use a ratchet spanner. Get yourself as many different shape 12mm (i think thats what they are) spanners as you can ;) Very tedious but after you crack it, it won't take long. As a tip leave the 2 easy manifold nuts to undo till last, makes it easier to get the hard ones off as there is no weight on them. Also don't be surprised if a couple of the manifold studs undo out of the block with the nut. The oil & coolant lines that go into the turbo are damm annoying as you pull the turbo/manifold out, they catch on everything and you'll need 4 hands..umm thats about all I can think of to help you out at the min. Im about to put turbo's back on mine. My rebuilt stockers fckd up in less than a year so im going a set of GTSS or some N1's. My MINES dump pipes got delivered today :D

if you need any help im in sydney too

Cheers

Try an extension bar with a uni joint working from under the front of the car, thats normally the easiest with the stubborn nuts. Use lots of crc before attempting it too.

There is no way to get to the manfold nuts from underneath (at least that I can see). The turbo is in the way. If I could seperate the turbo from the manifold, it would be far easier to get at the bottom row of manifold nuts, but its seems I am not the only person who hasn't been able to seperate the two despite what it says in the manual.

Lucien.

if you are finding it difficult to get the uni joint to stop from flopping about and going onto the nuts, then grab your trusty electricial tape and run it around the joint a few tumes. will be tight initially, but works a treat :rolleyes: you can also get really handy and use shrink wrap over the joint, then apply heat!

LW - I'm surprised you cant drop the turbo enough to clear, perhaps remove the metal oil drain direct from the turbo?

Forget Uni joints, get yourself a 12mm ratchet spanner or set of racthet spanners (it did cost me 80 bucks). Just like GTR032 I changed my GT-R turbos all by myself and yes it was an absolute pain in the butt at the time (since I have never done before) but is definatively worthwhile now.

I can tell you now that you will not be able to take those bottom nuts out (except for the ones on the rhs you can get to them with the ratchet) as you will not have the angle to undo them. Ratchet spanners will be your best friend in this case trust me. Its really worth it.

Oh what great fun it is to remove the turbo's on a GTR with the engine in the car.

I think I have done it so many times that I have it down to a fine art. I can get them all off pretty fast now.

As others have stated, get some cheap spanners etc and customize them. bend, weld etc.

A bent spanner with a socket welded on is useful.

Getting to the manifold bolts I drop the turbo enough so I can fit a 1/4 drive extension through the gap and put a 1/4 drive socket on the nut. It's fiddly... but works :rolleyes:

a set of stubby ratchet spanners are your friend. www.transquip.com

and yes, you might need all week to do it :D

Just wait until you have to put the damn things back on again, I found the bloody water and oil lines with Banjo fittings a real pain to get started without threading them

I managed to loose the washer under the water line. Far out they are thin. Hopefully not too hard to replace :confused:

I think you meant this Transquip: http://www.transquip.com.au/

Edit: Given the extremely small space between the runners, wouldn't a longer/thinner ratchet, not a stubby, be more appropriate?

LW.

umm the copper washers can be hard to find the right size, from memory we got new ones from Lee brothers in Paramatta.

I think we used stubbys but they can be a pain to put enough torque on as well. We had a set of long ratchet spanners as well but it depends if you want to buy one of everything...

    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
