removing a turbo on a swapped celica, i figured this is a thread for here, not mr2oc, since our cars are dif Options

[brianforster]

ok so my exhaust manifold is leaking again, i thought i had fixed the stud but apparently it came loose.. so now im going to helicoil it.

consequently, i also have another problem on my manifold, 1 of the studs on the turbo side of the manifold has broken off flush with the manifold. i need some help as to how i can get this removed, the stud broke off as i was trying to turn the stud out, so its in there HARDCORE, i dont know if an easy out will work.. the stud broke off flush with the turbo side of the manifold.

ok the backstory aside, i need to take the turbo off in order for this process to be as painless as possible, and the only guide i can find is like mega hardcore removing the turbo.

what id like you guys to tell me is if i am missing anything

(first off, i can keep the oil and coolant lines attatched to the car correct, i just need to disconnect them from the turbo?)

then i have to undo that big bolt that holds the turbo to the frame

then i have to remove all those bolts from the downpipe

then i have to remove all the nuts holding the manifold on

then the turbo and manifold will just come off as one piece, correct?

let me know if im missing anything.. im trying to get this all fixed up before the dyno next weekend.

that guide is even less helpful than the mr2oc one, what i was looking for is someone whos actually done it on a swapped celica, to tell me the bare minimum of things i need to remove to get the turbo out.

the problem with trying to remove as little as possible is whether or not you have enough room to work. Some times its just easier to take the long route and take everything off slowly. It sounds like you got all the basics down on how to remove the turbo/manifold.

I know if you want to remove the broken studs, you need to take a drill and drill them out. If our lucky a stud remover will work. If your unlucky you have to just drill the entire broken stud out and retap the hole to put in a new stud.

The last time i had to do this ( on a stock car) i had to remove the radiator to get enought clearance for the drill and drill bit.

the stud isnt broken off into the head, the head is just stripped, im going to helicoil it and since our heads are aluminum drilling isnt usually necessary.

Bare minimum:

intercooler piping and AFM couplers (2 clamps)
alternator bracket and tensioner (5 or 6 bolts)
lower downpipe connection (3 bolts)
oil supply/drain lines at the turbo (take out the studs not the nuts)
radiator hoses
TVSV vacuum line
heat shield (3 bolts)
exhaust manifold (7 or 9 bolts)

If you installed the turbo support bracket you'll obviously need to take that out as well.

If you take out the studs from the oil supply/drain hard lines you'll be able to slide the whole manifold/turbo/DP assembly forward and out the top relatively easily.

thanks wannabe, what about the coolant lines?

[WannabeGT4]

Oh yeah. Leave the water return connected to the metal radiator hose elbow and disconnect the rubber supply line from the hard water line bolted to the turbo...

wannabegt4 was exactly right, it was a very simple task, i cant believe i put it off for so long, took about an hour, hour and a half.

Glad to hear I could help. It's easy when all the information is fresh in your mind and you've been staring at it for a good three months.
