New Turbo Manifold Help
 
I need a new turbo manifold and I have a 1.6L with a TB28 turbo. I can’t find one that comes with a flange for my turbo (the one in the link is for a T25/T28). Does it matter what type of flange comes with it as long as it bolts onto my engine or would I have to order a flange for my specific turbo or would this product just not work for my model at all?
Thanks! (Link for possible new manifold below)

That product won't work for anyone, since it's made from pot metal and will literally crack and break within 500 miles of use.

So would something like this work? Or would it have to match my exact turbo or would it be fine since it’s just a 1.6?

do some reading and searching before going full noob.

Manifolds are typically expected to be able to bolt to the turbo they intend to expel hot exhaust gasses into.

So I threw you a bone and googled tb28 turbo. Apparently it has a t3 flange. The cast china mani has a t3 flange. It should work.

Cast Irion?

The Chinese manifold is probably fine. If it doesn't fit your turbo then you're going to have to buy a turbo. If it doesn't put your downpipe in the right place then you're going to have to buy another downpipe.

Never design your build around some random junkyard Turbo. They're so cheap. Get the right one for the application. Nobody usually turbos the 1.6 because of the limitations of the engine, differential, brakes, and other things.

Turbo manifold

Do you have a clue about anything at all? T25 turbo needs a T25 manifold. T3 turbo- T3 manifold. etc...

what do you currently have? post some pics of current turbo/manifold/dp setup.

It's a TB28 turbo. As sean already pointed out, it actually does have a T3 flange.

ok. But unless he buys the same exact manifold he has now, he will also need a new Downpipe made.

The one that came already installed on my friends car lasted 3000mi. And had a big hole in it by 5k.

Someone actuallt bought it for $20 after that (like, they offered him money for it. He was gonna just let it go with the turbo since it was bolted on already).
