first time i removed the turbo . the engine was not in my rx7. 2nd time i removed my turbo i took it out with manafold in order to swap from s4 to s5 turbo. i had to remove lower intake manafold to do so.
now i just need to change out the turbine.
is it best bet to just remove the turbo itself? or manafold too. meaning to remove all the intake.
i have been told that its easier to just remove the turbo from the manafold. and leave the manafold.
then remove the turbine off the hot side. since i know i cant remove the turbine alone when the whole turbo is on the car...... or can i?????

is it posible just to remove the front of the turbo, the turbine? we installed the turbo with hot side. then put in a different turbine then the one that came with the turbo. as shown here :

i'm guessing there is no way in hell to get that one bolt by the lower intake manafold. meaning its imposible to just remove the turbine ya?
i'm just trying to save myself some time and effort. and back ache :-P

well the last time i had to remove the hotside like that, i had to use lot of force and turn each bolt a turn at a time to get them to seperate evenly.

as for doing it under the car, i don't see it happening.

heh ya.... thats what i thought. i mean. the one who built my engine was able to put the turbine on the hot side when it was on the engine. but the lower intake manafold was not there.

WTF? You don't need to remove the intake manifold to remove the turbo. In fact it's the other way around; you need to remove the turbo to remove the intake manifold!

Since you're only working on the turbo, that's all you need to remove.

Correct.

The turbine is the hot side. The turbine is the rear section driven by the exhaust, the compressor is the front section that compresses the intake air and is driven by the turbine. The compressor and turbine sections are bolted to the centre housing.

You need to clarify exactly what you want to do...

lol dont be rediculious. hahaha. in order to remove the tu rbo manafold last time. we had to unbolt the turbo manafold and set it down. there was a clerence issue and we couldnt pull the turbo and manafold up straight threw with out removing the lower intake manafold. we had to unbolt the intake manafold and then that gave us clearence to pull the turbo and manafold out. sorry. but thats how we did it last time. since i was going from s4 to s5.

so. i guess i had to say it just right to not make you mad?
ok i had to remove the compressor and hot side from the. oh jeeze. why is this so complicated. i gave a picture because i didnt know the TECHNICAL terms for all that. i mean. didnt i say turbine?

to clerify. i showed a picture. but maybe you'd like to see more pictures?

heres a pic of the 3 turbos i pulled apart last night to inspect and pick which one i wanted.
i have to pull out my turbo because it has rediculious play in it and there is a puddle of oil on compressor side.

"oh well why didnt you just remove the turbo last time so you didnt have to remove the intake manafold"
to answer that question. because i didnt have enough money to spend on both new exhaust gaskets , k?

"on no that turbine is on the ground!!!" yup. those are the 2 bad ones. the one that is tinted red is the one i am using. cool hu?

oh theres only about 8mm of play in the shaft pulling back and forth...

if you unbolt the turbo from the 4 oil and coolant lines, then remove the intake and exhaust from it (which I assume you already have done) then there are only 4 nuts holding it onto the exhaust manifold. All of which are very possible to remove. Then you just pull the turbo out through the top of the engine bay. you may have to remove you're cruise control, but thats a hell of a lot easier than removing the LIM! Just leave the exhaust mani down there the whole time unless you have business with it.

This still makes no sense. You must have been doing something wrong because there is certainly no need to remove the LIM to get the turbo off. I've done it several times and I can't see how LIM removal could do anything but make the job harder. Go read both the Haynes and FSM instructions for turbo removal. Neither will mention the LIM. Search for threads on turbo removal and you'll find the same thing.

The turbo only has three main parts, from front to back; compressor, centre housing, turbine. Not complicated.

You did, and you said it was the front half, which it's not.

As long as they're intact, the gaskets are usually reusable. Smear a little high-temp sealant on each side.

just unbolt the whole turbo assembly from the manifold, it really shouldnt be a big deal. that way you can set it on a work bench and replace the coldside/bearing assembly.

no reason for the LIM to come off.

na you see, guys. back then i did have to take the lim off when swapping from s4 to s5 turbo exhaust manafold. i tried my hardest to remove the turbo WITH the exhaust manafold cuz i dont really trust high temp rtv directly on the turbo at the time. but now i do because i tried it on my down pipe componants.

as for this
yeah. and i removed all that out of the damn hot side. what ever you want to call it. what ever is one piece with the waist gate flap. which idk if you listed.

HENCE THE PICTURE.
complicated or not. i showed a picture because i did not know the correct terms for each. see the pix above? the turbines pulled out? ya. swapping that out.. see? see the oil in the turbo? ya. just got to swich that out. not the whole turbo itself. dont feel like porting another s5 waist gate thank you very much. not that complicated at all.

initial D is REAL!

remove the complete turbo first. I dont know what your planning on doing, but if u want to reclock it. Do a mock up and make sure everything is facing the right direction using a pen or whatever. Tighten everything back up and install the turbo completely together.

you wont be able to reassemble your turbo while its bolted to the exhaust manifold still. Is that what you are trying to do??

I really dont know how u took off you lim to get turbo off or on or whatever. Either way, intake manifold stays on

as in, red RTV??
or more like anti-seize? (like for 02 sensors and spark plugs)

initial D is REAL!

high temp is copper red one i believe

NZConvertible

I've done this a couple of times and I've never removed the LIM. You must have been doing something wrong. Did you follow the FSM or Haynes instructions? I'm not criticising you, I'm just giving you this info you that you don't make the same mistake again and to prevent anyone else reading this from making their life harder than it needs to be.

That was one mistake. Remove the turbo from the manifold, then the manifold from the engine.

Any sealant that says it's suitable for exhaust use should be fine. Not anti-seize...

I just came back as of right now from taking off the turbo and putting on a s5 manifold....U DO NOT have to remove the Intake.

I also removed it in one piece turbo + manifold

The turbo shield can be a bitch though

initial D is REAL!

Yo, is that red stuff on the turbine the silicone youve been using?
