oil and coolant lines are different. How the turbo connects to intercooler piping is different and larger diameter. I'm sure there are a few other things as well. I've never tried to put a t-25 on a 1g. Why don't you just rebuild the 1g turbo or contact @JusMX141. He's a beast when it comes to turbos. Hell, he might have something sitting on the shelf ready to go.

Ok, Ill probably just shoot him a pm then. I was just hoping it would work! Thanks

You said its old....you didnt say its bad. Elaborate please. Oil leak is easy to fix vs replacing a turbo and making it work

Well, I'm no turbo expert, but the 1g turbo had significantly more shaft play than my brothers 2g turbo. I don't exactly know where its leaking from, I have to clean all the sludge off and take a closer look. I just didn't realize the 1g and 2g had different turbos, that's my bad for not looking it up first.

It can be done. One of my good friends has a t25 on his auto awd 1G. It's not a direct swap though.

Alright, its leaking where the oil line bolts to the turbo, looks like it just needs a new gasket. How much side to side play is too much?

For what it's worth, I wouldn't consider putting a T25 on a 1G as a worthwhile investment unless it's temporary and the T25 is all you have as a T25 is truly not even close to being as durable as the TD04/TD05H units that came stock on 1G cars. If you want a quick-spooling alternative to the 14B, look into the TD04 13G which came stock on auto 1G's or even the TD04HL 13T which is the stock turbo from a RVR Sportswagon.

Ok, I don't care to replace the turbo, just had a 2g turbo available. I really don't care to do modifications to get it to fit, especially if the 14b is the preferred option. How much do you charge for rebuilds, or say I wanted to tackle it myself, do you have any videos or how to's on what I need to do? Also, I know I shouldn't be thinking of mods right now, but there's an evo 8 fuel pump for sale in the classifieds for 45 right now. Is that something worthwhile to scoop up?

Oh man, stick with the 14b or step up to a 16g. Sounds like the oil leak is just the gasket.

I thought the turbo on the 2g was smaller and worked harder. Isnt it a 14b for the 1g vs a 13g for the 2g?

14b is 1g manual, 13g is 1g auto.
t25 is 2g (auto manual)
I wouldn't go to a t25 from a 14b. we put a 14b on my brothers 2g and it made a noticeable difference.
