Here's the question(s)

RP uses garrett t-25 turbos for their upgrades

so what would happen if we kept the primary turbo stock (HT12) and changed the secondary to T-25?
how would the car react to this considering the boost is set to 10lbs?
would the manifold NEED to be ported?

any ideas, comments are welcomed
i'm trying to see other possibilities while maintaining the stock twins.

somebody did this already. They took the 2ndary turbo from 20b and installed it on the FD. I think the results were good, other then when the transition comes and the 2nd turbo kicks in, it gives you too big of a pull. you can do a search and see what you come up with.

Your sec. turbo will just pull harder as what boostinfd said. It may creep due to being a bigger turbo so you may have to port the wastegate but as of manifold porting, I don't think thats neccessary.
