Fuck everyone's horror stories about ebay kits. If you take care of them, keep the engine tuned properly, and keep them on low boost, they are fine.

thats about right, i had a ebay kit, and only issues was the manifolds cracking, wastegate leaking, turbo took a shit when i went over 10lbs.. But it was being ran @ 6lbs for the longest and it ran perfectly fine. But as soon as it went up to 12-15+ it took a shit..lol But well worth it.
