Hi Tommy / Scott
My Project is a boosted one, have tried three different Bosch coil's
P100-T - Great coil but too short does not reach top of plug
PS - Small and compact but low power would be difficult to mount without major mods to cam cover
P50 - Perfect Fit, but need to seal around plug hole in cam cover
Will almost certainly go with P50, with some sort of rubber grommet. will make support rail which will attach to the two centre studs of the the cam cover at each end.
Cheers - Jay
