Their manifolds crack but, once re-welded and braced are usually ok. I have used multiple of their FMICs @20-30psi without one problem. I have never used one of their turbos but, many of my friends have. Some of their turbos have gone bad quickly and some have lasted like a name brand turbo. I know of a 50 trim t3/t4 that has been used for two years and it's still going strong. With their turbos, you've got a 50/50 chance that it was assembled correctly. If you buy one, have someone that has experience with rebuilding turbos dissasemble it and make sure it's assembled properly. Then you'll have a much better chance of it lasting longer than a couple months. General rule of thumb: YOU GET WHAT YOU PAY FOR!
