Cast Iron 1jz Manifold

[Manuel89]

Hey guys,

I drive a Soarer with 1JZ with R154.
I wanted to convert to single.

my favorite picture from the previous owner of my car :naughty:

Where can I get a cast exhaust manifold ago for the 1JZ?
For the 2JZ that are offered, but not for the 1JZ?

Greetings from Germany

No one makes one. every JZ series motor does except for the 1jz and 1jz vvti. You could always be cheap about it and take the stock twin turbos off, use the factory manifolds with two joiner pipes from each 3 cylinder bank into one T3 or T4 flange. This works very well.

I could have sworn Treadstone offered one at some point, but that was long ago that I was looking, so I could be mistaken. Welcome to Supramania by the way.

What does the 1JZ vvti use stock? It's single, shouldn't it have a cast single turbo manifold stock? I see it won't fit the twin turbo 1JZ anyway though, different port spacing.

All turbocharged vehicles from factory use cast manifolds. I think what the OP is saying is that he was looking for an upgraded cast manifold. The 1jz vvti manifold from factory is cast with different port spacing. It uses a CT15b turbo with the same hot side inlet as a twin entry CT20b or CT26. There are manifold adapters that convert it to a T3 flange.

Like I said, you could use two joiner tubes to one flange using the stock cast manifolds or pick up an eBay china-made one but just clean it up.
