Terrible quality. The casting is really poor. Spent loads of time and money on labour trying to get it to fit but it wont. Also meant the turbo wouldn't fit. Ended up welding up my old manifold instead
I suppose it does it’s job in terms of it being the right shape but it’s not thick enough. There’s too much room in the cams so if you accidentally rotate the engine whilst it’s still in it doesn’t hold the cams in place, it just bends the locking tool. Not really doing what it’s supposed to
