anyone ever remove their greddy turbos with the engine in the car? Im sure some one must have had to pull a turbo here or there at one point to have it rebuilt. I installed my tt kit with the engine out of the car and really dont want to go through all the hassle of pulling the motor this time. Is it any easier to remove the turbos than install them with the engine in the bay?

 

Are you rebuilding the turbos or building the engine or thinking of selling the TT kit?

 

I have installed SEVERAL Greddy TT kits without pulling the engine. I have removed them without pulling the engine also.

When I was removing the 20g kit off my 350z before selling the car, I had the turbos and manifolds off in maybe 2 hours after the car was on jackstands in my garage at home... and I am not the fastest mechanic in the world either.

Make sure you have a few options for shorty 12mm wrenches to get to the one hard nut for each turbo. I have one that I cut to the perfect length. Since there is no room to get a great grip on it to torque it, or un-torque it... for that hard one, I put my shorty wrench on it, and use a prybar to do the torqueing... works every time. Even did the same trick when installing the 20g kit to my 370z with the engine in the car.

 

Note.. you will have to disconnect the steering shaft joint. Mark it all really well and then lock the steering wheel before you remove it. If you mis-align it here, it came become a hassle (the car has a steering angle sensor for VDC if you were not aware). Also, the starter will have to be pulled to get the passenger turbo out. Just pull the starter right away (disconnect battery first) to get it out of the way.

You will see that once you get in there, its really quite easy, only a couple nuts are hard to get at.

I have never pulled a VQ for the purpose of installing turbos. Only if the motor was being pulled to get pistons and rods first did I ever install the turbos to the engine without it being in the car.

 

gotcha. thanks for the input. I figured I would have to disconnect the steering shaft joint. Im pulling the turbos because Im going to get rid of it. sad time. but all good things must come to an end at some point. I'm just over it, thats all.
can the turbos and manifold come off in one piece or do I need to remove the turbo from the manifold to take it out of there?

 

ya the turbos have to come off the manifolds. its hard enough to get the turbos to fit around the bellhousing flange.. you have to be able to spin them around all funny to get them through. plus im not sure you would be able to get to all the manifold studs with the turbos on.

 

damnit. ok. i'll have to take a look at how I assembled them and asses this first.

 

just dive right in, its easy. Start up front and get all the intake pipes and charge pipes off. Then remove the downpipes and wastegates. remove oil drains. disconnect oil feed from front of the engine. then remove 3 bolts holding each turbo to manifold, then remove the manifolds. 2 hours of work once youre on jackstands.

 

got all the intercooler pipes and intercooler off yesterday. also go the oil return and supply lines off. then I ran out of time. going to try to pull the turbos off today. ***** getting real! sad to say goodbye. oh well.

 

the hardest part in removing the turbos was the forward most nut on the triangle flange. Like phunk said a shorty 12mm is what you need or some kind of combo thing. I've taken mine off twice. I say loosen the a/c compressor too...it will help get the intake pipe on that side out of the way.

Also, if needed you can loosen the v-band clamp holding the turbine hosing so you can rotate it out of the way. Removing the front cross member helps too!

 

so....... got the downpipes off and began my attempt at pulling the wastegate and housing off.... quickly said F this. Headed to grab a cherry picker from a friend. Its going to be much easier to pull the motor and remove things in this case. haha. it was worth a shot at least.

 

youre nuts... you could have that stuff out before youre even ready to take out the engine mount hardware.

 

Thank god I pulled the motor for this. Made it much much easier. Lots of stubborn nuts and bolts holding the turbo/wastegate/manifold together. There's no way I would have gotten it off without pulling the motor.
