need some help
 

alright so here's the deal im about 2 pick up an 89 240sx possibly two for 300-400 a peice both are in non running condition but can be running easily. I just need some advice on a plan of attack for building the car/cars.. so far i have a m/t swap planned and possibly a motor swap but i was just looking for advice on where i should go from there. The car is a project and i have an RSX for a daily so im not really pushed for time, but as far as what im going to do with the car im planning to start autocross racing and i want it to be fierce on the streets as well... just looking for any ideas for short term low budget and or long term high budget mods any advice would be greatly appreciated thanks
