Product Description

The Cometic PRO2021B StreetPro Bottom-End Gasket Kit is engineered for full lower-engine rebuilds of Toyota's legendary 2JZ engine series in 1993-1998 Supra, GS300, and SC300 models. Whether your build is the naturally aspirated 2JZ-GE or the turbocharged 2JZ-GTE variant, this kit ensures proper sealing of all lower-end components - oil pan, front & rear crank seals, main caps, and lower block joints. Its use of premium gasket materials (MLS, AFM, Aramid Fiber, ArmorClad) delivers durability at OEM-level and beyond, especially useful in high-mileage or high-stress engines.

This bottom-end kit is ideal for rebuilds or maintenance where the top end (head, valves, cams) remains intact or is being sourced separately. Because the head gasket and top-end parts are excluded, verify you have or order the correct top-end components to match bore size, compression, and performance goals. Also ensure proper torque specs, sealant surfaces, and alignment of internal oil passage plugs when doing the job. Fitment is confirmed through 1998. Models beyond 1998 (e.g. 1999 Supra revisions or other engine swaps) are **unconfirmed** for PRO2021B use.
