Compression Tested for Buyer Confidence

One of the most important factors when purchasing any used rotary engine is compression.

Compression testing helps verify the overall health of the rotor housings, seals, and internal components, making it an important part of evaluating a used rotary engine.

This package provides an excellent opportunity to:

• Source OEM replacement components
• Complete a period-correct build

For enthusiasts seeking originality, a complete JDM drivetrain package can significantly simplify the restoration process.

Excellent Foundation for Future Modifications

While many buyers choose to run the engine in factory form, the 13B turbo platform also supports extensive aftermarket upgrades.

Popular modifications include:

• Larger turbochargers

• Street porting
• Bridge porting

The strong aftermarket support surrounding the 13B platform continues to make it one of the most tunable rotary engines available.
