Product Description

The Cometic StreetPro Top End Gasket Kit brings race-proven MLS sealing technology to the 1988-1993 Nissan RB20 platform, a 2.0L inline-6 built in three distinct configurations: the single-cam RB20E, the DOHC naturally aspirated RB20DE, and the DOHC turbocharged RB20DET. This kit covers all three across Skyline, Silvia, and Laurel applications, so the correct top-end gaskets are on hand regardless of which RB20 variant sits in the engine bay. The .051" multi-layer steel head gasket handles the higher cylinder pressures of a built or boosted RB20 far better than a stock composite gasket, without needing the thicker gasket stack that can shift compression and quench height.

This is a complete top-end kit rather than just a head gasket -- it covers every gasket and seal needed for a full top-end reseal or rebuild in one box, from the intake and exhaust manifold gaskets down to the full set of 24 valve stem seals and the valve cover set. For the turbocharged RB20DET specifically, the kit includes the turbo-side pieces a generic non-turbo kit would leave out: the turbo inlet flange gasket, turbo outlet gasket, 10 turbo oil/coolant line washers, recirculation intercooler gasket, turbo compressor outlet gasket, and air release copper washer, all sized for the T3-flanged Garrett turbo setup this engine runs from the factory.

It's built for anyone doing a head gasket job, valve seal replacement, or full top-end rebuild on a 1988-1993 RB20-powered Nissan -- whether the RB20E or RB20DE is getting a stock refresh, or the RB20DET is being reassembled after machine work in preparation for more boost. A separate StreetPro bottom-end kit is available from Cometic for a complete engine rebuild if the bottom end needs attention at the same time.
