Always verify your engine's exact bore size before use. This tool is not intended for engines outside the specified bore range.

Installation

This tool is designed for use during engine assembly and does not require installation in the traditional sense. Slide the compressor over the piston and rings, compress to the specified bore diameter, align with the cylinder bore, and drive the piston in using a wooden handle or mallet. No special equipment is required beyond standard engine assembly tools. Recommended for experienced engine builders or professional mechanics performing FA20/FB20 engine rebuilds. Always follow OEM torque specifications and assembly procedures during engine reassembly.

Is this tool compatible with bored/stroked FA20 engines? This compressor covers the stock bore range of 83.05mm–86.87mm. If your engine has been overbored beyond 86.87mm, a larger compressor will be required.
