how to remove stock turbo (help please)

[qikr33]

hello every one.I have recently discovered that my stoko turbo has shat an oil seal.I am in the process of removing it and i have all intercooler piping out of the way.

I need help with the following

-where do i disconnect the dump pipe at the turbo or where it bolts onto the main exhaust (300mm away from turbo)

-what is the best method for removing the oil and water lines how do i get to the rear oil or water line right next to the exhaust manifold

-do i remove the exhaust manifold or just unbolt turbo from it

-when i pull water and oil lines off will i need to plug them up or will they not leak

-Are there any gaskets i need

-Any other information that may help me with the removal and installation of new turbo

Thanks in advance for anyone contributing any info,as you could probably tell i am planning to get the job done myself and have decided removing and rebuilding and high flowing original turbo,i know lots of people will disagree and suggest putting monster turbos and manifolds on but unfortunately this is the budget i am on, and have heard positive info from some reliable turbo re builders in bris.

I cant help you with all of these but i would say that it is easier to disconnect the dump at the turbo and get it out of the way.

I've done this before and it's very easy, I didn't have the heat shield so it took about half an hour working slowly!

I did this recently myself, bolting up my new turbo

where do i disconnect the dump pipe at the turbo or where it bolts onto the main exhaust (300mm away from turbo)

Unbolt it at the rear of the turbo, where the dump pipe bolts on.

what is the best method for removing the oil and water lines how do i get to the rear oil or water line right next to the exhaust manifold

I just used a 24mm (I think) spanner. It's FAR easier to get at it from beneath the car, get it on a hoist if you can. As for the other lines, they just unbolt.

do i remove the exhaust manifold or just unbolt turbo from it

Just unbolt the turbo from the exhaust manifold. There are four bolts, I think they're 17mm from memory.

when i pull water and oil lines off will i need to plug them up or will they not leak

They will leak, but don't worry about plugging them up unless you're worried about making a mess. Just top up afterwards.

Are there any gaskets i need

You may have one between the turbo and the dump pipe. The one between the turbo and the exhaust manifold should be OK to reuse. If the top oil feed on your turbo has the two-bolt connection and you undo it (you don't need to) then you'll need another gasket in there. It's advisable to replace the nylon bushes around each of the fittings into the turbo too.

Any other information that may help me with the removal and installation of new turbo

You should be able to find a bit more info in my other thread: http://www.skylinesaustralia.com/forums/sh...ead.php?t=30556

thanks revhead ,great help i will get this done soon and come up to the switch for some drag combat operation of my own!!!Once again thanks

[shoey_R33]

may i ask a question where would i be able to get gaskets for the turbo? i assume that places like autobarn wont stock import parts?

[qikr33]

i havnt got there yet i was either going to make them or ring a performance shop to see what they use.I think the other option is to use mastic or gasket goo

[Revhead]

You'll have a fair bit of trouble finding someone who stocks gaskets - Nissan doesn't list anything, Holden only list a flange gasket. Repco/Autobarn/Walkers don't have listings for them at all.

What I ended up doing was getting some asbestos extractor gasket material and cutting my own gaskets, but I believe this is illegal to sell as of new years', so you may have to resort to gasket goo.

qik, see you at Drag Combat

i got a gasket for the turbo/dump from drift king geebung.

nissan have everything for any skyline , u have to go to a dealer that deals with imports , not all of them do .

there are several dealers in sydney that do though .

shoe dgo to hornsby nissan they will help u , if they dont have in autralia they will order from japan about 1-2 weeks ( no charge for freight either .

if u r closer to parramatta go there but their spare parts is in rosehill .

turbo is off now took me 1 1/2 hrs gasket from turbo to dump pipe in good condition.The head was off the car about 5 months ago so most studs and gaskets are fresh.The only prob i had was unbolting water line that sits between turbo and engine but i left it till last as it was hard to get to and slightly kinked it but its fixed now.The turbo is now at Turbo Torque (used them before on my vl turbo and they were very affordable and dont add on extra costs ).Hopefully have it back in a week and then bolt it up and off we go.

Does anyone know if there is an air bleed screw in the cooling system on r33's.

Also is there a process to bolting back on that involves priming oil into turbo or any thing little that needs doing prior to starting the engine.

thanks again

sounds good wrx hoon but im in brizzy

[druzilla32]

how much is it going to cost to highflow your turbo?

[qikr33]

just spoke to rob at turbo torque .The turbo will be highflowed both compressor to t3 and exhaust.The skyline turbo is non repairable so he is using parts off a vlk turbo then high flowing to t03/t04 for $1450.

the new turbo will give 20-25% hp increase.

Just for intrest brisbane turbo and tuning quote 2100

Just incase you haven't found any gaskets yet, you can get them from GCG in sydney. They have a 3 gasket kit for 40 bucks that includes the t3 flange gasket, dump gasket and oil drain gasket.

They do mail order stuff too i think

[qikr33]

thanks bhdave get turbo back in 1 week so i will probably blast this site with countless problems.....hopefully not though.

[BHDave]

If you got it off then you shouldn't have problems getting it back on.

The only problem i had was the core was rotated very slightly, less then a degree, which made it a bit difficult to get the banjo bolts started. Other than that it was a piece of cake

[lukits01]

sorry for jacking the thread qikr33 have you fitted on ur turbo back yet?

cause Im also about to attempt to bolt on a turbo back exhaust

Are there any more gaskets on the exhaust besides the one between the dump and the turbo?

am I right to assume that the you need to replace that gasket once you remove the stock dump pipe?

[qikr33]

sorry lukits havnt bolted back on yet will do it on friday so i am not sure what gaskets i nedd.There is a steel gasket that i removed between turbo and dump pipe and i can surely re use this one as for the seal between turbo and manifold i cant remember but i will have a look for you and post again a little later.

[qikr33]

well its been almost a week and a half and i got the turbo back(will post pics soon).It all bolted together,i found that where it bolts onto exhaust manifold it had a steel gasket so i re-used it with some manifold cement as assurance of a good seal.The sam went for where it bolts onto exhaust manifold it also had a steel gasket.

Only dramas were finding new copper washers for the banjo bolts...only place i found that had them was lewis hoses (slacks creek near moss st) cost me $3

before i started the car i pulled the fuel pump fuse from the boot and cranked the engine over for about 30 sec to get the oil up to the turbo(as it said to do with the card that came with it.)Took it for a drive and it takes a few revs to spool this baby up but then when it hits 10 psi it really has some get up.I need a new bov as the stoko one isnt letting enough air out now between changes and sometimes you get a fluttering noise.Started raining so i couldnt put the boost up any more but will be as soon as it stops but definitly more lag and hopefully more power.

i will post more stats up when i get a chance to thrash it a bit more. :wassup:
