FAQ

Q1: How do I verify that this overhaul set fits my specific S4S engine?
A: Confirm your engine serial number and cylinder block casting number. This set is designed for standard bore S4S engines. If your engine has been previously rebored to oversize, please contact us with the current bore measurement. We recommend cross-referencing your existing part numbers (e.g., from your old pistons or gasket set) against the 32A17-00100 reference.

Q2: What installation precautions should I take with this kit?
A: Always clean the cylinder block thoroughly before installation. Use new oil seals and apply thread locker to main bearing cap bolts as per Mitsubishi service manual torque specifications (e.g., main bearing bolts 98-108 Nm). Pre-lubricate piston rings and cylinder liners with clean engine oil during assembly. After installation, prime the oil pump and crank the engine without fuel until oil pressure registers.

Q3: Can this kit be used for turbocharged S4S-T engines?
A: Yes, the 32A17-00100 kit is compatible with both naturally aspirated and turbocharged S4S variants. However, if your engine has higher power output (e.g., S4S-T rated above 70 hp), we recommend upgrading to heavy-duty pistons with reinforced ring lands.
