ENGINES
Our main focus is the L-series (6cyl), but we do L4, R16, and U20 engines as well.
We offer 5 stages of engine builds, in addition to a stock rebuild. We are beyond an engine assembler or a machine shop. We design and develop our proprietary engine parts to use in our signature series builds to maximize the performance, reliability and longevity. The stage-2 and up will come with value added items, such as a signed and individually numbered engine plaque, a Certificate of Authenticity, and an Engine Score Card.

STOCK REBUILD
We do more than performance engines and we can do stock rebuild. If Keeping it stock is your goal, we can help.
*Note: E31, E88, and some early N42 cylinder heads came with brass intake valve seats intended for leaded-gas setup. These brass valve seats are, without exception, eroded and must be replaced. These heads are found on the 240z and 260z, and some early (1975) 280z’s. This is the reason for the higher price than the L28 Overhaul.
