Here is a k20 turbo kit as a log manifold I had on my ep3 however will be universal for any k20. It is 850 as it isn’t a complete kit there will be some things you need to replace like the intercooler and some silicone hoses will meet to be replaced as they were torn. The kit made 400 bhp and was strong just struggled with access so caused reliability issues. I also have more ep3 things for sale as well
