i got an on3 kit on my car i just upgraded to the master power 76MM with the maf from on 2 had right at $2000 in the kit.I like it.my builder bitched about the fitment some and the V-band clamps are not all that good you may have to get a few better ones but not replace all of them.my last turbo kit was mostly chinese that we pieced together off ebay and bough master power turbo for it and i had a little more in it than buying the kit from on3
