As its a 95 Civic, it will be having Carburated Engine ! I would say leave the other parts of the car for now, just get a D16 from 97-99 Model Civic which will be for around 40K (Not confirmed) and if you give the original engine, then the price will be reduced to maybe 30 thousand !
You will notice a gr8 increase in performance and later when you have more money, you can install performance parts to increase more powerr ! Cheerz !
