engine and gearbox

KNOWLEDGE BASE: want to share your knowledge of this engine swap? Email me your tips and I'll post them here.

ENGINE: The s14 engine could be described as the ultimate evolution of the m10 that originally came in the 2002. As such it shares the same engine mounts, can take the same sump so it fits over the 2002 subframe, and generally drops straight into an 02.

GEARBOX: There are a few options - basically any gearbox that fitted upto an m10 has the same bolt pattern and should fit up to the s14. Most common is the OD getrag that came in the e21 3 series and is a common upgrade to 2002's. This box bolts right up and fits the transmission tunnel without amy major work.

This option will require you to have the motronic sensors for the ecu installed into the bellhousing. You'll also need to shorten your prop.
