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

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.

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 ;)

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
