Maybe a new turbo kit coming ?
 

An interesting article on motoIQ, it would be sad that after all the R&D it would not be produced.

I think the new Garrett 25 series, either 550 or 660, would have allowed more options. They have a V-band turbine inlet with an internal wastegate that would eliminate the need for a dump tube, simplifying the plumbing in a very tight area. SOS's kit does this, but with an older Garrett turbo and 5-bolt downpipe interface rather than a V-band. P-Tuning had a ramshorn manifold with external wastegate, but they including a dump pipe that merged into the downpipe. @yamahaSHO used an IWG BW EFR 7064 turbo on a custom ram's horn manifold with a twin--scroll T4 turbine mount. The G25 IWG is single scroll V-band or rather restrictive T25. I think people have hit over 800hp on a T25. However, the EFR is a 9-year-old design, the G25 is new. In some tests, people have found the EFR has minimal if any spool advantage over the current Precision turbos, but they don't have IWG. The EFR has a recirculating BOV built into the compressor housing and a 3-port boost solenoid on the compressor housing further simplifying the installation. In the small frame models, is available with a housing that has a 90° or in the aftermarket even swiveling 90° outlet.

Although I haven't seen anyone do it, using an IWG also provides the option to use an electric wastegate actuator eliminating the boost solenoid entirely and the related vacuum lines. This would drive the wastegate directly from the ECU and is common on production cars, but virtually non-existent in the aftermarket. The compressor maps in aftermarket turbos are also much more aggressive than production turbos.

Very cool. This looks really nice. I can't wait to see the final product.

I would've certainly preferred an IWG turbo for myself (if I ever were to consider adding a turbo which doesn't look very likely right now), but Khiem obviously has different ideas/plans than a track turbo car now so he's doing what's best for him and his goals. Very cool article seeing how prototyping can be done these days. Definitely excited to see the final product.

Pay attention to this picture and how the wastegate actuator hangs out from the centerline of the turbo. It's very unlikely the wastegate actuator would fit given the tight packaging constraints.
