Drop in Garrett turbo?

It looks like I値l be getting back into a 9-5 as I am picking up a 2000 Aero MT tonight. The car has a lot of miles so I figure I値l be replacing the turbo at some point.

I also now work for Honeywell, and you may know that Garrett is owned by Honeywell. I知 looking for a Garrett turbo that will bolt up without large modifications and support stage 3. I壇 like to 徒eep it in the family so to speak. I致e done some searching, and it seems that most people are upgrading the mitsu unit to 19T.

Any recommendations on a Garret unit?

Thanks for the help.

The TD04 should work fine with lots of miles. But its a T25 flange, so you could do a number of different garretts.

A GT2560 or a GT2860R with a conservative tune, fueling and injectors would likely fit the bill.

...but it still is subject to all the inherent issues

Thanks for the responses guys. Picked up the car last night and amazed at how well it runs and drives with 250k miles. Motor sounds great, turbo boosts wonderfully as well. It has trouble getting into reverse, but I haven't looked at it and first I suspect a linkage or shifter alignment issue.

Saabeh, you are right, the mits unit seems fine even with this high mileage.
Mike, what inherent issues? Are Garrett units in general not reliable? I know the gt17 was not, but thought others were much better. I don't know much about turbos aside from how they work. I don't know the naming conventions etc to make me knowledgeable about picking one out either.

No, no...sorry for the confusion. I didn't complete that sentence and it is really unclear that I meant the inherent issues with the B235.

The TD-04's (as long as they are rebuilt correctly) are extremely bulletproof. The issue with the GT-17 is they seem to be more sensitive to sludge related failures, and the turbine housings crack around the wastegate opening and the crack opens up and contacts the turbine wheel and it chews itself up.

Someone else will have to pipe up if there's a drop-in Garrett GT series. At worst you'd have to make up some custom lines.

It'd be worth a call to Nick Taliaferro (a phone call, not an email) since he'd probably be able to tell you off the top of his head.

You're sort of stuck with drop-in upgrades.
T2 turbos aren't really plentiful, and certainly not in the upgrade area.
One of the old Nissans used to use s GT28 that is an upgrade, but not by a whole lot.
The big issue is that the turbo, itself, is the bottle-neck.
The manifold can be ported some, or you could use the 9000 manifold with the t3 flange.
I believe there's a little work to be done there, but the 9000 manifold has MUCH shorter runners, fatter-runners, and the ability to be opened for better flow.
you'd need, at minimum, a different downpipe, and possibly some work to clear the water-pump, but in my eyes, it's a more performance-oriented option that opens the doors to the piles of t3 turbos.

The GT2560 (GT28R) has a T25 flange, and you can likely have lines made (or bent to match) fairly easily. It's not big enough to need a manifold spacer like the GT30 series, so you should be able to have a V-band welded to your existing downpipe.

The compressor wheel on this one is about the same size as a 19T, IIRC, but the turbine wheel is only a bit bigger than the one on the 15T, so it shouldn't be a lag dog at all.

Thanks guys. I didn't get the notification that there were more responses. Not sure what I'll do yet, but I've got some "keywords" or starting points to go search and do research.
