Which turbo do you think is the biggest you can go and still autocross with either a 2.0ltr or 2.3ltr? Yes, make your selections for both sizes of motors.

 

Anyone have a general opinion about this?

 

You said CAN, you can use as big as the engine can handle. IMO I wouldn't go bigger than the 20g, white rabbit, or TME 6.5 turbos on the 2.0l, but that is my own personal pref.

 

what about the 2.3 ltr. Is there anything out there that falls in between the 3076 and the GT35. A turbo that works good for the 2.3 for autox.

 

for autocross you prolly spend a lotta time off the pedal so you want max boost response and fast boost up.

for a 2.0 liter get the evo 9 jdm rs turbo with the magnesium wheel and then get ti wheel for the hotside.

for a stroked motor get the gt3076r turbo.

both these setups will basically spool faster than stock, the first will limit you to about 370hp on pump and hte second will put you at around 430-460 on pump (this one is a ruff guess, really depends on how much the stroking buys you in hp).

 

i would do a turbotrix 50 trim with a 2.3.....that would make for a nasty autocrosser

 

i LIKE THE 3076, that is the turbo I will be putting on in the next week
