FAQ
Reader questions
What models does the Tomei Poncam KA24DE kit fit?
The kit is tailored for Nissan KA24DE engines found in vehicles such as the 240SX, certain Altima and Maxima models, and other platforms sharing the same mill. Always verify engine codes and block years before ordering to ensure correct pin heights and bearing sizes.
Do I need to machine the bearings if I choose this kit?
Tomei Poncam kits are produced to close tolerances and usually require no under sizing or polishing of bearings. However, verify main and rod specs against your block measurements and follow the installer’s guidance for any specialty applications.
Can this kit support forced induction or higher compression upgrades?
These kits are engineered for reliability in light performance use, but adding turbochargers or substantial compression increases may require stronger rings, forged components, and professional tuning to manage cylinder pressures safely.
What break in procedure is recommended after installation?
Use a high quality assembly lubricant, avoid wide open throttle for the initial drive, and vary engine speed through the rpm range during the first hours. Monitor oil pressure and perform the first oil change with a filter to remove any microscopic debris.
