Default Evo III 16g good on 2.5??

Basically what the title says. Is the E3 16 good on the 2.5?? I was looking at the ones from FP. I can also get a pretty good price on a VF34, how would one of those do on the 2.5? Im not looking for a lot of power, but I want a good upper end. I have only ever seen these turbos localy on 2.0s and they rock.

How would the 16g or VF34 compare to a VF39/43?

Me, I think it's a reasonable upgrade, though many members would agree that 18g/20g is more reasonable.

If I were to get the evo3 16g, get the 8cm hotside.

I think its a perfect turbo for the 2.0l for a daily driver, used to run one myself. I would bet that it would taper a bit on the topend on a 2.5l. Its a great turbo, but i would say 18-20g for the 2.5L

If its between the VF-34 and the 16g, I'd go Evo316g all the way

both are mild upgrades over the vf39/43. most will agree that all 4 turbos mentioned are too small for the 2.5 (evidenced by boost tapering to redline). if all you want is 300/300, then the vf39 is your best choice for bang for the buck. the vf34 flows slightly more than the vf39/43, but you have to take into consideration price vs output.

for $100 more, look at the 18g with a 8cm hotside instead of the 16g. a lot of people agree that the 20g 8cm is 'the' stock location turbo for our 2.5s but that all depends on what you want out of the car.

They'd be improvements over the stock turbo but not much improvement and not worth the effort.
