I have a S14 SR20DE RWD from Japan not the FWD motor - its not the turbo model though but the good thing is it has no oil squirters so you get better oil flow for the bearings where you need it most.
Previous owner tapped the coolant drain hole for turbo and also tapped the upper oil pan for turbo - so its all ready for turbo use.
Its the bare block, main caps, girdle - $150 in Concord, NC 28025
