Tools & Materials Needed

Before you start, gather these essential tools and materials:

1. Wrench set (metric and standard)

2. Ratchet and socket set

3. Torque wrench

4. Screwdrivers

5. Pliers

6. Oil catch pan

7. High-temperature anti-seize lubricant

8. Fresh engine oil

9. Clean rags

10. Safety gloves and goggles

Step-by-Step Installation Guide

1. Preparation & Safety Measures

Before beginning the installation:

1. Park the vehicle on a level surface and allow the engine to cool.

2. Disconnect the negative battery terminal to prevent electrical mishaps.

3. Drain the engine oil to avoid contamination during installation.

2. Remove the Turbocharger

To access the CHRA, you need to remove the turbocharger:

1. Disconnect the intake and intercooler piping.

2. Remove the downpipe and any connected vacuum or oil lines.

3. Unbolt the turbo from the pedestal and carefully lift it out.

3. Disassemble the Turbocharger

1. Place the Turbocharger on a clean workbench.

2. Mark the alignment of the compressor and turbine housings before disassembly.

3. Remove the compressor housing bolts and separate the housing from the CHRA.

4. Remove the turbine housing bolts and detach it from the CHRA.

4. Install the New SPOOLOGIC GTP38 Billet Wheel Cartridge CHRA

1. Ensure the new CHRA is clean and free from debris.

2. Align the CHRA with the markings made during disassembly.

3. Secure the turbine and compressor housings to the new CHRA using the original bolts.

4. Apply anti-seize lubricant to the bolts to prevent future seizing.

5. Reinstall the Turbocharger

1. Carefully position the turbocharger back onto the pedestal.

2. Reconnect the oil feed and drain lines, ensuring no leaks.

3. Reinstall the intake and intercooler piping.

4. Reconnect the downpipe securely.

6. Final Checks & First Startup

1. Double-check all connections and fasteners for tightness.

2. Refill the engine with fresh oil.

3. Reconnect the battery and start the engine.

4. Let the engine idle for a few minutes, checking for oil leaks or abnormal noises.

Pro Tips for a Successful Installation

1. Prime the CHRA Before Installation: Add a few drops of fresh oil into the oil inlet to lubricate the bearings before the first startup.

2. Check for Boost Leaks: Inspect all intake and intercooler connections to ensure there are no leaks, which can reduce performance.

3. Monitor Oil Pressure: After installation, keep an eye on oil pressure to ensure the turbo is receiving proper lubrication.

4. Avoid Over-Tightening Bolts: Use a torque wrench to tighten bolts according to factory specifications to prevent warping or damage.
