I lay it out for all of you. I bought one of the first three kits Terry made for the MP3. There were some fitment issues at first, and he sent me a new one. Then about two weeks after I had it installed, I ran over a retread from a semi tire and this knocked my oil return line off my oil pan. I didn't know it was off until my oil lamp came on and by then it was too late. My engine was shot, and so was the turbo. Since I was so patient with Terry, he felt that he should help me out. Since he had a warranty on the turbo, he returned it and got a refund. He also built me a completely new manifold. So the turbo and the manifold are brand spanking new. I bought the intercooler on my own. I built all the charge piping. Some kits such as the FM have some 2.5" and some 2" piping. I was able to make all of mine 2.5". This is an advantage over others. I believe Mazdaformance is also building theirs modeled after mine. So this is basically a Spool stage 2 kit, with the stage 3 intercooler upgrade and all charge piping. The only thing I don't have is the downpipe and the Tial wastegate. I was using a Garrett T3, but I decided to go with the Mitsubishi 16G the second time. I have not re-installed anything because I haven't gotten my motor rebuilt yet. So the kit is basically brand new. If you have any further questions about whats in my kit, I have a complete post on all of this in the for sale forum and the forced induction forum.
