GSR swap in 95 Dx

I am considering the purchase of a junked GSR from a fellow locally for the sum of $1200. It is a complete car, and runs great. It has a little over 100K on the dash, but no damage to the interior, engine, or transmission. Are there any chronic issues, or is there anything to watch for with this type of swap?

I am unsure of the yr of this car as well, so i am wondering about maybe an OBD conversion, if the gsr is OBDII. How much trouble would it be to do?

THe car already has mods, such as skunk2 cams, cam gears, header, exhaust and some suspension changes.

newb/ricer question:
What kinda 1/4 mile times will i be looking at?

Any tips/suggestions about this particular swap?
