hi, i have a ATP GT3076 turbo kit fitted to my evo 9 i would like a better spool from this turbo and have read about billet compressor wheels which should spool faster and give more top power.

so is there a chance to upgrade my turbo ?

i mean fp sells a gt3076 hta , would this compressor wheel fit my turbo ?

thanks for your help !

 

billet compressor wheel should increase response, but it wont be a lot of difference.
Have you thought of going to a twin scroll manifold and exhaust housing?

 

would like to stay with the atp kit

but faster spool would be nice...

i am as well thinking about getting a 2.3 stroker

but a hta upgrade would be the cheaper upgrade
