Our new Twin kit

[zayrx7]

We are completing this kit and will be taking it to the dyno soon, these are gt28r turbos with a v-mount set up.

Pics of the manifold please!!

[zayrx7]

We aren't releasing pics of manifold yet! we will after we dyno tune the car for results.

Pics of the manifold please!!

No needs pics! :D

It's single pipe from the exhaust port to the turbo turbine inlet.
WG's are integrated, so no mess of pipes just for the wastegates.
You can get an idea of the pipe routing just by looking at the location of the turbos.
Single pipe "downpipes."
"Hard" part is all the merges - both inlet and exhaust side of things...

BTW, those look like GT28RS's?
I don't think they are the larger GT28R's, since those run the larger T4 compressor covers...

Do you see IWG's on the turbos, also they are gt28r. Do I need to take a pic of the invoice just to prove they are what they are.

No, I do not SEE the wastegates in your pic.
Sure, you're welcome to use EXTERNAL wastegates on your turbos.
GT28's all come with internal wastegates?
External wastegates just add to complexity, which in turns adds costs to your kits.
If you're trying to keep costs down, adding external wastegates doesn't make any sense.
If you're trying to make a no-cost-limit kit, then add the complexity with external wastegates.

"GT28R" is a FAMILY of Garrett turbos.
The "GT28RS" is just one model under the "GT28R" family.
Why don't you tell us what exact GT28R model did you use instead of getting your panties in a bunch?

His panties are constantly twisted.
IIRC this was already done @ RX7store.com, car made 450whp @ 17psi... again... IIRC. I thought about doing this, then realized I could make better torque/power, less complexity, less heat etc etc... the only thing I'm missing is the larger price tag and the ohhh snap factor. Aside from that... meh.

Now.. if it was a compound turbo setup, then I would be interested.... but looking at the pics and seeing two identical turbo's... no... no its' not

I'm just waiting to see the manifold. I'm looking forward to more of those AMAZING pie-cuts...



:suspect:

[zayrx7]

I was the one who installed that turbo kit at rx7store, that kit was a pain in the ass. We couldn't get the turbos to stop surging against each other, this manifold is nothing like that. I don't remember that kit making 450hp, will need to go back and check that.
