Product Description

The Cometic PRO2021T StreetPro Top-End Gasket Kit is engineered for the Toyota 2JZ-GE (non-turbo) 3.0 L inline-6 engine for 1993-1998 Supra, GS300, and SC300 models. It provides a complete top-end seal package: a high-quality MLS cylinder head gasket matched to the standard 87 mm bore and .051-inch compressed thickness, along with camshaft seals (front & rear) and timing cover seal. This ensures excellent sealing performance, especially in older engines where sealing surfaces and stock gaskets have degraded over time.

This kit is ideal for anyone doing a rebuild, major service, or restoring a 2JZ-GE non-turbo engine, and wanting to maintain or renew all top-end sealing surfaces. Before installation, verify that your engine is indeed 2JZ-GE (not GTE), that the head/block surfaces are in good condition, the torque sequence/specs are per factory spec, and the compression ratio will be maintained with the .051-inch head gasket. Fitment is confirmed through **1998**; years beyond that (e.g. 1999+) are **unconfirmed** for this part number.
