EP85 or EP95?
Its very straight forward. I have mentioned in loads of various old threads all the parts you need. Its going back a few years now since i converted my 85.
You can turbo the 4efe that comes in it, they are ok up to about 0.6bar on a standard turbo ECU. Higher compression ratio than a turbo engine.
Not sure what fuel you have.
You will need the 4wd sump modified to accept a turbo oil return line.
FTE parts to get, or upgraded.
Not all of this is needed, depends what route you want to take.
Engine ancillary loom, plugs direct into the standard fuse box.
FTE coil igniter
Inlet & TB
Thermostat housing sensors to match loom (water lines, optional)
PAS pump and line (optional)
Dash, clocks & loom (optional)
Flywheel and clutch
Civic dual core radiator
