you are looking at twins then and considering the turbos are about 3-4k by themselves you see how it can get expensive very fast. thats gotta be a turn key system also because you can find twin kits with a tuner system for 6k5 new. so you figure 3-4k for turbos, 300-700 for uprev, fuel injectors, fuel pump, intercooler, all that piping, ect ect. yah you will spend more then 8k for it. i was looking at building my own kit and was looking at about 7k for what sasha offers alot cheaper if i built it myself.
