Hey guys, I've finally gotten around to pulling my turbo manifold off, I've just run into a problem though... Last bolts I have to undo are the bottom mounts for the rear manifold (the ones to the block, three of them), the "L" brackets that support the manifold, the join between the exhaust housing and the beginning of the exhaust pipe and the oil feeds. Now, he oil feeds are hard to get to (going in from underneath), are they going to spew oil all over my face when I undo the bolts? As for everything else mentioned, the bolts are so damn tight, the top bolts I got off by putting a piece of pipe over the end of my socket wrench, but there's no room for that down there :-( Any advice?

Remove the L brackets first as they give you more room to get to the oil feed/returns. Which are not under pressure so therefore no oil will spurt out, there will be a very small amount of residual oil in them.
Lock a second nut onto the turbo to exhaust y piece to try and remove the stud , rather than remove the nut. If you can do this then the front turbo can be removed straight off.

Hose the bolts with wd40, rp7, rost off , whatever you can get and do the other jobs first to allow some penetration time.
Try to interlock two spanners, that is put the spanner on and then put another spanner into the open end of the first to increase the length. Only use good quality spanners to do this as you don't want them to break as you will certainly hit something with your hand.

Hope this helps.

I used a long shaft 14mm ring spanner that i purchased from repco.

PS oil will not spew out.

good luck you will need it

Cheers guys, yeah I've been smashing my hands all over the place lol but not serious damage so far... I don't have a hydro jack so things are pretty cramped under the car, not a lot of room for leverage. I've covered the bolts in CRC but it hasn't done much so far, that was about 2 hours ago. I'll keep trying and keep things posted, any further help would be good :-)

I used a 14mm u shaped ring spanner I got from Aussie auto.

They are designed for hard to get to places.

Hahaha......Sorry Tim. I have changed the twins twice and feel your pain,The swear jar must be full by now......Hahaha
Keep going mate and you will get there.

PS: Taking them of is easier than putting them back on......Hahaha

Advice when it come's time to remove the oil drain and feed lines,Don't and I will repeat DON'T push down on them as the rubber hose will brake and give you a big problem.
To do it right you have to undo the transmission line's so you can drop the oil drain line's down.

i to am feeling your pain, i did it 3 times on my brothers car. and 2 times on my friends car.
and in the end i could do it in about 2 hrs.
leave the exhaust housing on and split the turbo's and change the front housing and centre. leave all the exhaust side of things on the engine. really it only the centre you need to change unless it has rubbed the compressor side of things..

get my drift?

Yeah I think so, but a big problem there for me is getting the exhaust flange unbolted, what an epic, epic, epic C*NT! I got a 14m ring spanner around it, absolutly soaked it in CRC, left it overnight and still, no budge. I got a nice long pipe for ultimate leverage, pulled with every fibre of my being and it just bent. Even under the car, the next flange along doesn't want to unbolt, I'm thinking about just getting the grinder out, take the heads off the bolts, might be my only option at this stage :S but taking the centre out would make sense, there would be a lot more room to work on getting the turbos off.

I need to change the turbo seals, or maybe a turbo, something in there is buggered (see my "suspected blown head gasket" topic). I've split the centre, almost got the front turbo off, with one last bolt holding me back. It's at the back of the oil feed, any tips? I have a feeling I may need a deeper socket, I've only got the regular cheapies (and they're not even mine haha), I had a tool theft tragedy a few months back. Cheers for the help so far.

Ok I've got the rear turbo off, it wasn't easy (and I'm certainly not looking foward to putting it back), but I did it :p
The flange for the oil feed, if I look inside there it is rather disgusting, normal? Also, there's a small amount of oil on the exhaust end of the turbine, very little but it is there. The turbine doesn't move back or foward at all, but it does move up and down, very slightly, about half a millimetre in any direction, is that normal? I'm planning on taking it somewhere to get it checked, would a regular mechanic be able to do so? Cheers for the help guys.

Well done on the removal.....Haha...So how much is in the swear jar?

So the turbine dosn't spin freely? If not then she is stuffed,And with the oil on the exhaust turbine I would say the oil seal is gone.Time for a rebuild or single turbo option.
These are your options,
1,Go single = Between $4000 to $6000 depending on what is needed.
2,Rebuild and high flow your ct12a's = Around this price

3,Replace with second hand turbo's = Between $250 to $400 and who knows how long they will last.

The turbines spin just fine, I don't think I have the budget to go single, although that would be nice, I may go for a rebuild.

A BFH should fix it Joel! Hahaha
Only drama is you might snap a stud in the turbo.

I can see mine have been removed before, I have a stud snapped between my rear turbo exhaust housing and the centre piece that joins the two turbos to the exhaust pipe.

Joel - I found it easier leaving the manifold stuck to the block and unbolt the turbo from the manifold (three bolts), it's still tricky, I used a ring spanner, got it over the right bolt head (obviously the bottom two are the hard part), then sat a long solid piece of rod I had laying around on top of the spanner (no room for hands down there) and gave it a couple of taps with a rubber hammer. one it was loosened off it was a simple case of slowly unscrewing it.

I actually went and saw my (tradesman) nieghbour, he lent me a really grunty socket set, helped me big time. A few of the bolts had to be gotten from underneath with epic-ly long extensions and a flexy here and there, was not easy haha, seriously considering having a mechanic reassemble it...

Ok so I've rang around a few places, took the turbo to a mechanic who happens to own a 1JZGTE Soarer, and knows them inside out. Appearently in NZ, the only parts available are the steel turbine, hi flow everything upgrade... It's going to cost me about $3000 to do the whole job, but the mechanic said he'd have it boosting 16-18 psi by the time he was finished with it. Sounds ok I guess, not to happy about the price tag though, but he was definatly the best that I saw.

Talk to the mechanic and see if there is a finance option.
