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.

DISCLAIMER
The listed engine prices do not include core engine charge, installation, setup, tuning, or shipping. The engine price is for a bare engine (Fully assembled engine, with valve cover, oil pan, and oil pump). It does not include any peripheral parts (i.e. carburetors, exhaust, ignition system, harmonic damper, water pump, alternator, manifold stud kit, starter, flywheel, clutch, thermostat, etc) Any and all peripheral parts are offered separately.
We recommend using new rocker arms and adjustable cam sprocket and valve timing work (Stage-3 and above). Customers are to provide core engine, or need to purchase one from us.
Prices are subject to change without announcement.
We have limited availability of core engines, and we may not always have the exact head/block combination that you desire. Core charge for an engine is TBD. (Very limited availability).
Notes:
• A core engine must be re-usable.
• Special repair work (i.e. warped head, corrosion, cracks, rust, broken bolts, undersizing crankshaft, sleeving cylinder, etc.) will be invoiced separately at cost.
• When sending/bringing a core engine, please remove intake/exhaust/clutch/flywheel
You may send/bring us the whole engine assembly with manifolds and other peripheral parts, but keep in mind doing so will incur labor to remove these extra parts.
Any further questions? Please contact us.
