If I wanna modified the civic with turbo , is this a big problem for me? My car is orginal I changed muffler and open air filter. Everything is orginal in the engine how can I modified the car with turbo system but I dont want to change anything? Repairman said that about turbo system. If I want to put turbo system He said that "-We will cut your pistons on the top. is this good or bad, and how much psi we will in engine?
