i bought 2 turbos and i don't know which one is best for my car. the car is a '99 SiR.

Turbo A - the seller said it's a T28 but i think(not sure) it's a bored out T25.
Turbo B - the seller said it's a T3

difference between turbos are:
- turbo A has a larger compressor blade as well as inlet.
- turbo B has a noticeably larger turbine housing as well as turbine blade compare to turbo A

is it possible to swap the parts so i'll have the best of both worlds??

which one should i choose????

lastly, where do guys get your coolant source for your turbo?

thanks.

depends what your looking for? the t28 is great turbo for instant lower boost, and the t3 is great for more upper mid, high end power!! i like the t28!! good luck, eric

thanks. anymore inputs???

I assume an SiR is a B16? If so, I would go with a minimum of a T3.

yup it's a b16. could you please tell me why is T3 better than a T28? how can i tell if it's really a T3? how bout T28/T25? i'm kinda new to turbocharging. thanks.
