Cast Twinscroll Long Runner Full/Partial turbo system group buy

Does the Rx7 forum think there is enough interest for a full or partial Cast Long Runner EWG Turbo System Group buy?

Basically we would do either an SXE, EFR or TDX based kit;

Turblown Engineering RX-7 TDX61Turbo System

Turblown Rx-7 BorgWarner Airwerks/SXE Turbo System

Turblown Investment Cast 347SS T4 Twinscroll FD3S Turbo Manifold Group Buy

What are the primary benefits of the long runner set up, as opposed to your cast shorty?

Its for external wastegate turbos.

Also, it would be a more budget friendly option for people who don't want to spend $2,000 + on an EFR turbo with the internal waste gate.

Most of the new single turbo builds are using Borg Warner's Airwerks series of turbos ($600-1000) and this manifold would compliment them well at less than $800.

I say there is no reason for you to NOT be already making these.

We are moving forward with this, and will release a bunch of information soon.

You can see we have scanned the welded version in CAD in the videos section on our FB page

http://www.facebook.com/Turblown/
We are now reworking it for optimum performance. We will release a new video soon showing the exact changes and how it will outperform the welded versions.

Looks good Elliot! Would these guys come with the option of ceramic coating?

Are those wastegate flanges for the TiAL 38mm wastegates? Also, I assume they'll fit the larger EFR turbo's just fine, correct?

Its going to be around 6-8 weeks roughly for the batch of 100 units to be finished.

These are flanges for the turbosmart comp40 wastegates, but the Tial MVS( 38mm) also fit.

Yes this fits all of the EFR EWG T4 turbochargers, all S300SXE. I haven't test fit the new S400SXE, but the old S400SX units do fit( I suspect the S400SXE might not, as the X models have bigger compressor covers).

What is the weight difference between this cast unit and the similar SS model?

Out cast IWG manifolds weighed slightly less than the welded version.

I expect the new EWG manifold to weigh a little bit more, as the main runners are larger for some distance. This will naturally add more weight. Our cast manifolds are no where near as heavy as OEM cast piece, or cast iron pieces like the HKS manifolds.

The guys from Vic Time Attack are going to test out one of our samples early next month. The car is a semi pport 2 rotor running an EFR 9180 with the T4 1.45 housing. Car made 600rwhp last year on the 1.05 housing. Car is fully instrumented with turbine shaft speed, EGT, and exhaust back pressure .

^ How tight is that with some of the larger turbos, like an EFR 9180?

1.05 clears fine, the 1.45 is a tight squeeze against the OEM LIM( still has clearance, but not much)...

Are there any test fit pictures in a car with a/c, heat hoses, etc.? Looks great in a stripped down body.

Good deal! I'll be running a 1.05 9174 in mine. I just need to get permission from "the boss" to siphon off some money for one
