you sir, are a fucktard.
you will need new mounts to do this swap. since the del sol was later offered with a b16a3 from the factory, you could consult your local honda dealer to get OEM mounts, shift linkage, axles, ECU and dizzy from the VTEC model del sol, but that would probably be more expensive than getting nicer, stronger, aftermarket mounts and axles.
hasport is known to be one of the better companies for engine swap motor mounts, but other companies like place racing and HCP also make em.
you are also gonna need a number of other parts like axles, shift linkage, ECU (with an OBD conversion harness if its different than your cars), dizzy etc. depending on what you are getting with the purchase of the motor, and what year it is from. if its a USDM b16a2, then its from a 99-00 civic si, which is OBD2. your car is OBD1. some changes will have to be made there.
as for the labor, 800 would be a good deal if the mechanic knows what he/she is doing. motor swaps are not all that difficult, but they dont just 'drop right in' as mr. fucktard up here seems to think.
good luck and keep us posted.
