Ready to take your STI to the next level? That’s why we created the “boost” Party Pack! Includes the items we suggest for running the X500+ turbo:
BCP X500+ Turbocharger
Grimmspeed 44mm EWG Up Pipe
TiAL 44mm Billet Wastegate (black)
All necessary gaskets and vacuum lines
These items will offer the best performance and boost control from the X500+ so whether you want to start at 10 psi, or 25 psi, these components will allow you to do it. We suggest the “fuel” party pack as well for any application making over ~300whp.
