I have a first gen 4g63 and i want to upgrade the turbo. I'm wondering if i should go with a big 16g or something bigger.

 

20G...
well what mods do you have.. and what HP do you plan on getting out of the car

 

pulleys, 3in. exhaust, wires. I'm looking for 350hp. If i go much higher i'll need to upgrade my internals.

 

well if you want an easy 350 with room to improve get the 20G if you want 350 and max out a 16G then it is withing the HP range you want.

But youll need a tune, injectors and fuel pump at the very least if you want to get there

 

where is a good place to get one?

nothing for 3g =[

 

what would you even need lol... you still got a ways to go to max out the turbo your running
