What's out there?
I've got a Greddy 25G like below, but I haven't seen any manifolds with the 3 bolt connection. Would I be well off to get a new exhaust housing and a 4 bolt manifold? Or keep my exhaust housing and find a 3 bolt manifold?

grab another one and get this:

That looks like it might have a 3 bolt TD04 turbine housing, unless it's some kind of rare Mitsu/Greddy turbine housing. The hot side is too restrictive for what you're trying to do. Here are the factory TD04 3 bolt turbo manifolds on a 3000GT



Here is the Rmagic Rx-7 twin turbo manifold that 87 t-66 linked to:



Does Greddy/Mitsu even have any other 3 bolt turbo flange that isn't TD04 or smaller? What car did this turbo come off of? The TD06 turbine housings have a regular T3 footprint (for example, GMC Syclone TD06-17C) and the TD07's are T4.

I can't be going with twins using a turbo as big as this
I originally had 2 - I got them from a guy that was using them both on a high hp Supra. I'll get some photos of my actual turbo and put them up to see what you guys think.

Here are the dark, low res photos of my 06H-25G. That hot side looks tiny... so a bigger exhaust housing would be the way to go, no?

You have a hybrid turbo. That is not a TD06 hotside. Take a look at this TD06-17C, the factory turbo off a Syclone:



That's a T3 flange. The Rx-8 Greddy/Mitsu TD06-18G (aka Greddy T618Z) has a T3 flange as well.

You're right... I was just reading off the label that's riveted to the cold side
Any suggestions as to what hot side housing to pick up?

Looks like I might want this?

In terms of fitment it might work, but without physically looking at both the turbine housing and your current turbo it's hard to say. It's interesting how the ebay ad labels it as T4 footprint but TD06 as opposed to TD07. The Greddy TD06-20G kit for the Rx-7 has a T3 footprint I believe. You always have to be careful when looking on ebay for parts... lots of stuff will be slightly mislabeled. Most T4's will be called T04E even if it isn't a real T04E for example. Just a little FYI: A 25G is sometimes called a Greddy T67 (not the same as Garrett T67). It's called T67 because it has a TD06 family hotside and a TD07 family compressor. A T78 would be TD07 hotside and TD08 compressor. So you can have a TD78-33D for example.

In terms of size, 16 cm^2 is perhaps medium sized on a rotary. It would be good for stock ports with a focus on spool. You will see a lot of guys with half bridge ports run 20 or 22 cm^2 hotsides on Holset turbos.

Thanks for the info... you obviously know a lot more about this stuff than I do
I'm not looking for a huge build, and I'd like a reasonably quick spool
I'll probably go for that housing (or a similar one) when the time comes
