Brettus Turbo IV Garrett G30-660
I figured now that I have the actual turbo in my possession it's a good time to start a new thread. There has already been some discussion on this over in my turbo III thread (discussion starts here : https://www.rx8club.com/series-i-maj...2/#post4932196 ) .
Reasons for choosing the Garrett 30-660 : finally there is a no compromise, high flow, quick spool, compact turbo that will actually fit nicely on the Renesis in a low mount position.
Goals:
1/420-430whp
2/Widest power band ever seen on a Renesis
The setup :
Garrett G30-660 1.01AR
Manifold : self built log style (see Turbo III thread)
Wastegate : 38mm Tial
Intercooler : Custom vibrant vertical tube
BOV : Synapse DV
Fuel : modified stock pump basket with 340l/hr AEM pump
Injectors: OEM brown P1 , uncapped yellows P2 and sec
Tuning : Bretttus self tuned with Mazdaedit
Huge thanks to Gregs for hooking me up with this little beauty!

Here are the 3D prints for the first production run. These are all spoken for . Should be turned into cast stainless in the next few weeks covid lockdowns permitting !

Brett, your never ending quest for small improvements is a great story to follow. Having learned a ton of things about turbos and related items from your previous thread I will be following to see how this turns out.
Maybe make a few extra manifolds to sell in the RX8 market, I'm certainly not the only one interested in purchasing it.

sure there are, but we can save that for my thread
on 2nd thought, it may not work out on RHD. So for your situation that may be correct. Keep forgetting that the toilet bowl swirls in the opposite direction down there than up here.

G30-660 vs GTX35 (To4b) They look very similar . G30 comp hsg is slightly bigger than the TO4B , GT 35 is slightly longer (center of turbine to center of comp outlet). The 30 has a 0.7AR vs 0.6 for the TO4B ..... Garrett did a lot of work to get a larger AR within the same dimensions.
The GT35 turbine (top) supposedly flows the same as the G30 (bottom) . We will see................
Took a couple of attempts to get compressor lining up just right . 1.01 Turbine housing is very tight fit but at least it does fit. Barely enough room for my heat shield.

I'm curious to see what type of response you see from switching from the T04B hosting to the new one. I was running a GT3076R with a T04E compressor housing and I switched to GTX3076R with a T04B and there was a noticeable difference in torque below 5K. The GT30 felt like it had more power down low but it fell on it's face up top. The GTX has more airflow based on the MAF readings and doesn't fall in it's face up top. I think I'm going to switch back to a T04E in the future.

sometimes that's a good approach, just walk away for a bit and come back with a fresh perspective.
you'll figure it out, just a matter of time.

sorry for your troubles and also sounding like a broken record by asking again, but will a T3 turbine housing help?
Was also curious to confirm the ID of the turbine inlet manifold adapter flange; thinking it should be approx. 60.xmm ID?

Team , it's nothing to do with that. The turbo fits fine .
It's just me atm.
Re the adaptor..... Don't have access to it any more but we discusssed it in the other thread and I gave you a dimn. (measured with vernier calipers).
