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!

 

a friend has an FMIC on his car from them and it is holding up pretty well. not a problem with it even after its hit a parking curb or 5 and the part is over 2 years old.

 

Some of the newer SSAC manifolds are actually pretty decent (certainly not on par with the high priced ones though). They have bracing and are welded different than their 1st gen design. I had a buddy run one for almost 2 years without any problems. He had a flex pipe though, so that might have helped.

 

^flex pipe is key! Without one, any non-cast manifold will crack. Also, bad motor mounts will kill manifolds.
