which turbo kits better?
 

can anyone know which turbo kits better for rx7?

depends on hwo you will be driving the car and under what conditions. IMO, there's no turbo that better than all the other turbos out there in every single category, do a search for what you want to do

maybe the question you should be asking is...what's the best turbo kit out there. i mean if you want to ask which turbo kit is better you need to give us choices.

btw. i prefer the hks to4r.
