Heres something I haven't seen before. A wastegate plumbed into the turbine housing.





I found it while browsing reddit and wondered whats the proposed pro/con of having a setup like this?

Link to thread where I saw this

1200+HP Nissan Stagea - MGAWOT?? : cars

 

If done correctly it is the ideal location for a wastegate.

 

I don't see the being much of a difference from a traditional internal wastegate

 

And if done poorly is a complete abomination.

 

The new EFR turbos have the WG on the turbine housing

 

Yeh but no one seems to want to try one on a Rotary

 

been done with the stock turbo's (non twins) before.

 

It's just an internal wastegate using an external wastegate LOL. Nothing special.

Very popular here in OZ on VL turbos and Skylines.

 

That's because they're so expensive no one really wants to be the first to try it and melt it
Wish I would have ordered one as I could have paid out for the stupid expense by now with it taking so long to recieve them

 

Not really the case. The internal wastegate versions have smaller housings so the non-wastegate versions are preferable for our motors. Plus its like impossible to get one of them to begin with.

Yeh I know, I have actually held one, although it was one of the smaller versions, at the local turbo shop.

I know everyone is thinking the WG is maybe too small but it would be good to get a turbo system in one package and simplify the manifolds and fitment.

Your looking at £1,800 for the largest EFR here in the uk.

How much would a turbo, BOV and WG cost all together?

 

It also makes the fitmit of the turbo harder to do.

 

Probably the biggest reason for doing it like that was space constraints. It looks pretty tight in there and I doubt there's any room for wastegate runners in each cylinder manifold runner for a wg.

 

It took me a minute to think about what was going on there. Then I got it. Ok. Neat.

 

i am thinking the opposite, if the wastegate was on top of the turbo it would be the easiest thing to work on or adjust.

i would love to do this, but i have a divided housing... and that would be a mess lol
