This is a summary of the E46 LSx conversion. There are other links with more detail of the components of the project.
The donor was a Pontiac G8 GT with an L76 (LS2 short block with LS3 heads and manifold). We also brought with it the 6 speed automatic (6L80E) transmission.
The engine and transmission were transplanted into a E46 (BMW 3 series coupe).
The customer’s requests:
BMW to remain stock in appearance, inside and out. All the components work – Heater/AC, PS, ABS, original gauges, BMW shift selector,…
Other items:
– Reinforced sub-frame rear and front (M3 tower brace, lower custom steel tubing)
