How do you change a turbo on a 1992 eclipse?

Answer 1

From the top side under hood, disconnect the air tubing (2" hose) from inlet and outlet of turbo fan. Remove air cleaner and piping assembly, be careful not to damage the MAF sensor locatedin the intake body. Disconnect water lines (5/8" hoses) going into and out of the turbo body. From underneath: Remove downpipe (exhaust section between turbo and cat) you will need to unbolt a couple brackets that hold that in place, make sure you put those brackets back when installin new turbo as they support the weigth of your exhaust sytem. Follow the 1/4 oil line from the oil pump (lower front of engine) going to the turbo body, there should be a union about half way along the route, this is the easiest and safest place to disconnect the oil line, it is very dificult to remove from the turbo body when the turbo in installed. Carefully remove the oil return flex pipe from the turbo body, You don't have to remove it from the oil pan side but the pipe can be cracked easily if over flexed so for the price of a new gasket, I would recomend removing the entire pipe. Back to the top side: remove the sheilding around the exhaust manifold, disconnect o2 sensor from harness (located under radiator fill hose). Remove the (4) 14mm bolts securing the exhaust/turbo adapter block from the exhaust manifold. Turbo should drop out the bottom still attached to the exhaust port section. Once you have that whole assembly out of the car then you can remove the turbo from the cast iron part fairly easily. I have had success rebuilding my turbo with a cheap kit ($70), it does not pass oil anymore but seems to lag a bit more than it used to. It is tricky getting the oil seals in correctly and the instructions that came with the kit really suck so if you are going to pop off your turbo, you might look into replacing it with a new one. Hope this helps.
