only problem it may create, is how much psi you will be able to get out of 2nd larger turbo, to not overspool the first smaller one. but if you are using a t3 and a t4, on the motor you will be using them on, you wont be able to use the t4 to its potential.

two t3's? why? when one is enough, all you will do is make more power (that you dont need, cant control,cant get traction, and have to have complete faith inthe builder of your motor)
even then, you wont hit full spool (unless its like 5 psi, then it goes back to how stupid haveing two turbos is for 5 psi) til very close to max rpm, then it will break the tires loose, redline, and you will have to shift, and you will have gotten 5 feet.
i think you jsut want what sounds cool, not what works.
