Product Details

The BorgWarner 11631008001 is a precision-engineered turbine housing designed specifically for EFR (Engineered For Racing) B1-frame turbochargers. This high-performance component features a 63mm turbine wheel inlet with a 0.85 A/R (area/radius) ratio, optimized for balanced boost response and top-end power delivery.

Key Features:

  • EFR B1 frame compatibility for 63mm turbine wheels
  • 0.85 A/R ratio provides excellent balance between spool-up and peak power
  • V-band inlet flange for secure, leak-free connection and easy installation
  • Integrated wastegate flange (WG) for external wastegate mounting
  • V-band outlet flange (VOF) for flexible exhaust routing
  • High-quality cast construction designed for extreme exhaust temperatures
  • Precision-cast internal geometry for optimal exhaust gas flow

This turbine housing is ideal for performance enthusiasts and professional tuners looking to build or rebuild EFR turbocharger systems. The 0.85 A/R ratio makes it well-suited for mid-to-high horsepower applications where both quick transient response and strong top-end power are priorities. The V-band connections simplify installation and allow for easy turbocharger removal during maintenance.

easy ordering and fast shipment

Product is great

Good price.

THMotorsports always take of me when I order parts from them

Good

Petty good

Good price. Amazon filling ship and billing easy

Is to navigate. Found most of the parts I needed and GREAT prices.

So far, so good!

Best price I could find anywhere! I was called to make sure I really ordered it and it was not fraud! Never had a retailer do that before! Will buy from again!

super easy checkout with amazon link! Let's you know if in stock or not, which is critical when ordering racing components.

the product reviews all seem to be reviewed of autoplicity's service instead of the item being viewed. either way, the shocks ordered were the right ones w/ all the parts w/ it. autoplicity's item descriptions could be a little more clear and/or explicit

Great price and easy to use sight

Very easy. Tried O'Reilly's and that was a pain. I'm ordering from Australia.

Awesome deal

Great price!
