If you can get some of the crap out of the way you should be able to read the markings on the snail side of the compressor. I think in 89 they were mitsubishi's but I cannot say for sure.

 

Just checked it, its a mitsu...

 

I have a good mitsu for $30 +shipping

 

1989 used the Mitsubishi TE04H turbocharger. I'd suggest going with a larger Garrett turbocharger, but if you desire to stay with the Mitsu, there usually are a couple for sale on the boards here. I have an '88 Mitsu kicking around the garage. (If you're interested, PM me, I can send some pics out.)

 

I'm running stock so I always keep a good spare. I haven't seen any on ebay lately.

 

So the main installation difference between the garrett and mitsu being the hoses for the oil and coolant?
Also to replace the turbo, I'm thinking I will have to take the intake manifold and fuel rail off, can any of you guys with experience confirm this or enlighten me to any better way or trick?

 

although its possible to get the turbo off w.o taking anything off, I dont recommend it. LOTS of cussing will be involved... And goodluck getting the intake on and off. Sorry but the truth is the easiest way to change the turbo is to pull the entire head, turbo and intake manifold as one unit. Plus you can redo the headgasket, redo your gaskets and make it reliable. Otherwise, goodluck. A garret IS TONS better on a 2.5. Great upgrade. Spools better then when its on a 2.2 and all the sudden you will notice a MAJOR power difference in the upper end.
Plus with a garret you can run a 3'' exhaust with out having to worry about the boost control unlike a mitsu which loves to boost creep.
You can adapt the lines to fit on the garret but I would get a set of braided lines for the car for safety sake and longevity.
BTW welcome to the boards.

 

Welcome to the forum DirtyDuster!

 

The turbo can be ran without the coolant line.

Any sound from the turbo is bad though.

 

If you stay with the mitsu turbo it is not to bad to change just the turbo out. I just did mine on the 90 daytona. From under the car you need to unhook your coolant line and the oil return line. From the engine compartment you need to remove the throttle body for clearance and unhook the water and oil line. Then you can remove the v-band clamp holding the turbo to the manifold and manuver the turbo out the top. Oh yeah, either unhook the leaver on the wastegate or remove the two bolts holding it to the turbo. It took me about 20 minutes to pull mine and about 30 minutes to install it. If you have questions on this shoot me a PM. I do this stuff for a living and since I am basically lazy i tend to find the easy way to get things done.

 

Thanx for all the advice guys, my summer break starts in two weeks, since you can run the turbo w/o coolant lines, I'll keep driving as is, and then see about getting my hands on a Garrett and install while on break.
As a side note; I think the screeching was the alt, I replaced it late tonite an will be testing it tomm.. Sure hoping that was it.
