I have a 2001 ex and I was wondering If my eventual goal for this car is ~200whp would a t25 be ok or should i go with a biger t3 or t3/t4 hybrid?

Also if I ever did want to go over that 200hp mark would i be able to upgrade the turbo easily by changing the mani and turbo or would there be alot more work involved?

 

Do the math and figure out what air mass flow rate you're looking at for 200HP, then see which turbo would best suit your ride. There are many differences in OPINION about what setup is better depending on what people want out of their ride and driving habit.
