Thread: Turbos that work on a 4BD1.

Compressor is Garrett A/R 80 M24 (T25g I think)
Turbine is Garret R64

Is this worth putting in, is to too big and what sort of performance would it produce?

I'm just looking for a bit more juice from the old girl, especially on the hills so I don't have to change down so much.

Definitely a bad idea to fit this....really bad... but I'm happy to buy the kit off you to fit to my County....errrrr I meant ease your pain

I’ve never understood the markings on Garrett turbos. I would take it to a shop to see what they say.

If it’s the T25 fitted to the Perentie 6x6 then you should know many people have upgraded these.

T28 size (or T3 which can be broadly similar other than flange size - there’s lots of variation within T3) generally seems a better turbo for these motors.

Seriously... is this worth pursuing or should I bin it and buy something new?

Can you put up a photo of the setup so we can have a look at it.

I know this is probably not exactly helpful to answer question "Turbos that work on a 4BD1.", so I apologise, but I would just like to share some information I gathered when doing research for which turbo to choose, I haven't found a more suitable place for it.
This information is gathered from the Internet, so may not be 100% accurate.

Nice chart.

A few of us run the TD04HL-19T including myself. I have the waste gate wired shut. Usual driving up through the gears I hit 18-20 psi. Can easy get low 20's pushing it up a hill. It builds pressure quite fast at low revs, so lag is not an issue. I would certainly buy this size again if I needed a new turbo.

I get up to 25 psi out of my T28R, with wastegate de-activated.

Just me being a smart-arse. I can't really comment about the actual turbo, I don't know enough about them. As to turbo-ing the beastie I can't say I've heard to many arguments against it other than overdoing things and breaking the gearbox.
