Hey guys just wanted your opinions on which turbo i should get for an 03 wrx with 3" tbe, 255 walbro, cai, bigger top mount and ecutek. I have the 550cc sti injectors waiting to go on aswell.

which would give more torque and come on early.

was looking at the gtps01($1390) or a vf34($1400-$1500ish) or theres a as new vf34 $800, everything is new bar the turbine wheel as it was damaged in freight so theres a secondhand turbine wheel which has been cleaned, dynamically balanced, assembled and V.S.R balanced(i dont know what all that means). Also has a warranty if its stuffed in anyway i can return for refund.

I've also been told 180kw to 190kw will be the limit on a standard 03 wrx, what are the weak parts that would need to be upgraded if i wanted to go further.

Thanks
