Helpful Notes

• Goal-based sizing: HX35/HX40 or small S300 for towing/street; larger S300 or S400 for higher HP; compounds for wide torque with low EGT.
• Oil supply/return: Always verify feed pressure and use a high-flow -12AN drain on S300/S400 to prevent oil backup.
• Boost control: Fresh actuators and adjustable wastegates stabilize boost and reduce creep on HX35 setups.
• Heat management: Turbo blankets reduce under-hood temps and can improve transient response.
• Pressure test: After install, pressure-test charge piping to 20–30 psi and re-torque clamps post heat-cycle.

Frequently Asked Questions

What’s the best turbo path for a towing-focused 12-valve?

Stay conservative: a healthy HX35/HX40 drop-in or a small S300 keeps spool fast and EGTs in check. Add an adjustable wastegate and heat control for stability.

When should I choose compounds?

If you want low EGTs at load and headroom for higher horsepower—kits like the BD Super B Twins or Crazy Carl’s S300 2/3 deliver broad power with strong drivability.

Do S300/S400 installs need special oil drains?

Yes—use a -12AN drain kit or compatible OEM drain tube to prevent oil pooling and smoking.

Will a new actuator help my stock HX35 hold boost?

Often yes. Options include the aFe 46-60118 and Banks BigHead 24328; for fine tuning, add the BD 1047150 kit.

Which supporting parts should I refresh during a turbo swap?

Replace the oil feed and drain, inspect boots/clamps, and consider a turbo blanket for heat control.
