I am looking to uprade the turbo in my truck. I decided on getting a 14cm exaust housing and having it ported. What are my options on the compressor side? Should i just get a whole new turbo. I've heard mix reviews on the hx35 vs hx40. Or can i get just a new compressor housing and wheel to bolt to my current turbo. End goal whould be 350 -400 horse. Thanks
