ok the motor is an rb25det s1.
my goals are 400hp and retain some form of response or realy not having a very lagy turbo.
the two turbos i have are:
Garrett GT3082r, .63 rear ext gate
HKS TO4S, .7# rear or and option to use a larger .8# rear ext gate.
now i know the Garrett is ball bearing with the smaller rear but i have read they suffer compressor surge??? and the HKS is old design and not ball bearing so i can expect it to not be as responsive as the Garrett.
i drift ALOT so i want a turbo that is going to be usefull to me.
What would you choose of the two.
Thanks, Steve.
