In
mid-2009 we worked directly with IMI to develop a
never-before-available high-torque gear reduction starter for the
Porsche 931. As it turns out, the OEM 931 starter was superseded to an
OEM 951 part, so it has commonality with the later 924S, 944, and 951
models. Even better, by reversing the rotation, the same starter can
also be used on the normally aspirated 2.0L 924. IMI-155CCW
/ IMI-155CW Lightweight,
high-torque, gear reduction starters for the 924, 931, 924S, 944, 951

Looking for
Donors We
would like to expand the product line to include any auto-trans
equipped 924, 924S/944/951, and any 968. If you would be interested in
participating and can send us a sample starter (functional or not),
please contact us.
