Hey guys I was looking at all these turbos, and there are so many different ones like t25/27 td04-H and I have no clue which ones would go on my car, can some one tell me which turbos would be a replacement or upgrade that I should buy or can buy

And also what does the G stand for like 9g 11g
Thx I know thats a lotto ask but plz help if you can

Any turbo that is TD04 is a bolt on turbo.

What are your ultimate goals for the car? How much power do you want? How much money are you prepared to spend?

ok so any td04 as long as it says TD04 I can out on, I am going for a replacement or maybe just the next upgrade. I dont even know any prices, What would it cost to just replace the turbos and how much would it be to upgrade to the next highest thing.
