Hello there,

I need to exchange my turbo, is it doable without any specific tools or would I better

be off having this done in a professional workshop?

I'm meachanically inclined and have replaced cylinderheads, exhausts, clutches, and so forth.

But this time the car sits in my garage, so I have no means of jacking the car up and work beneath it (if required)

Thanks,

Andrew

Hey mate,

as long as you have a set of ring spanners and/or adjustable spanners you will be fine, I did fine.. some spots were a bit tricky, im about as knowledgeable with cars as you and it took me 5-6 hours working while having a few coronas :cheers:

Just remember to keep a bucket to catch the coolant that comes out when you remove the banjo's

Best regards

Hi there,

Thanks for the input ...

5 hours with a few beers sounds alright (factoring in one hour to remove all the piping), but I'm a bit concerned about having no ramps ..

I have only theoretical knowledge of the turbo mounting from the workshop manual.

It seems to be straight forward though with just a few known unknowns.

From the looks of it would I have to support the downpipe/exhaust once the connection to the turbo is gone?

Is it difficult to lift the turbo off the manifold and out of the engine bay?

Many thanks,

Andrew

Hello there,

Many thanks for the encouragement :)

I had a look and it looks like a job I could do (given I have no workshop )

As for an approach, is it ok to separate the turbo from the exhaust at the connection dump-pipe to down-pipe?

(That's what I would do ..)

Also a friend told me that the studs at the manifold to turbo connection tend to crack, and that I should exchange them while at it?

(They didn't crack for 13 years ... and removing studs from a manifold might be tricky)

I got a quote for the work from a guy who usually does these things .. (on weekends and without invoice etc.)

AUD 310 labour + parts!

I found this a bit steep .. or am I wrong?

Cheers,

Andrew

I will get an axle-stand !

it isn't that hard to do. takes a few hours (5-6 hours as said above). the oil and water lines are a bit fiddly. jack stands make it a bit easier (easier than ramps since ramps get in the way a bit).

If you put it this way, you're right.

Though he will not need 6 hours but rather 3 since he is a professional and has done this many times.

In addition the $$ go directly into his pocket and there is no invoice or official warranty ..

Thats a very good price. Think about it. 6 hours work $310

=roughly $50 per hour which is half of what a workshop would charge

Edited by Torques

Personally I never trust anyone offering me half price work so unless you really trust this guy, Id say for peace of mind keep your 300$ ( use it to buy good jack and axle stands ;) )and do it yourself, its a pretty easy job and if you think you can do it, you can..just unbolt the dump from the back of the turbo, I found these much easier to do than the 3 bolts joining the front pipe to the dump pipe as these you will find are rusted in hard..

But...

while the manifold/turbo studs should be fine, its the studs at the manifold/engine that crack mostly mate, usually 2 or 3 at either end..i had to replace 5 which also means removing the exhaust manifold which is easy enough ,but drilling out broken studs and replacing them is a prick of a job for a non professional without the proper tools, I didnt even attempt it..You will be lucky if none of them are broken and i would definately be checking this while your in there. I got charged 120$ to do this alone but its a cheap price for peace of mind...plus then you will need a new gasket, 30$ on ebay or 100$ from nissan, i got one on ebay and its doin fine..

Hi there,

So you just removed the dump-pipe from the turbo? This might have some advantages.

I will see if that works for me since there are 6 screws which might be quite rusty...

(compared to 3 nuts at the downpipe)

As for the studs at the manifold, if there is a cracked one and it sheered right off it will

be difficult to drill them out ..

Checking the studs could be done by knocking slightly with a hammer on the nuts which hold the manifold.

(at least in theory and from my experience with other cars)

I'll count on my luck here I guess, there's no blow-by or anything funny ... and maybe the problem is not

persistent with Spec2? (I'm sure there must be tons of mails regarding this, so I will do some (re)search.

Many thanks and cheers from London,

Andrew

You will need to get under it for sure closedeyes.gif would love to see a video if done all from the top. I've had the turbz off 5-6 times now, all up on jack stands.I find it easier if you take the turbo out with the dump attached. That way you don't snap the studs/bolts on the dump.

Take all the intake piping off the car, unbolt the power steering res so you can move it round, unbolt the cat from the front pipe.

Then under the car take the oil return line off and cover the barb on the engine so you dont get shit in there. Take both water lines off. Take the oil feed off. Take the O2 sensor out.

Lift the turbo out with the dump attached.

The water banjos are large 22 or 24mm. So make sure you have a spanner that large. You will need new crush washers for the oil and water lines, your local auto store should have those.

You will also need new manifold to turbo and turbo to dump gaskets.

Spray the shit out of the bolts with WD40 and let it sit before you attack them. If they loosen then get tight again, make sure you tighten 1/4 of a turn then try and loosen again. Keep doing that till it is off. Else you may snap it.

Getting is out is not that hard, getting the water banjos back on is a royal PITA.

Dont beleive me

threads like this popup almost weekly... :laugh:

are you still running a standard dump John?? Whats with that..Why no 3 inch, you have changed your front pipe yeah?

I couldnt get the 3 bolts undid on mine, it doesnt really matter which way you do it I guess, but now I have a one piece pipe so it has to be undone at the turbo anyway

Thats not a very fair comment. Some people actually enjoy working on cars and helping people out. Not just out there to get rich.

U don't trust a person but u trust Ebay gaskets lol

Sure I do believe you, I just hope I'm lucky ...

Since this is going to happen in the parking garage I need to keep

work as simple as possible, so I don't want to remove the manifold if possible ..

Cheers for that,

I will also need a new unrestricted oil-line for the hybrid-turbo.

In 2 hours I got this far, I hope the turbo will be out tomorrow ->

I'm surprised how tiny the turbo is and especially the diameter of the compressor-wheel looks really smallish .. I'm starting to wonder if it's really worth highflowing this thing ;)

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
