Planning my turbo set up

If it's not a daily driver I would even consider a 9lb flywheel. Imo a turbo s2k is much faster and more fun than a sc one making the same power. Honestly making 400whp is rather easy for a f20 or f22. Instead of making a custom exhaust have you considered an e cutout?

One big difference between PTuning and SOS is the wastegate. SOS uses an internal wastegate (which I'm usually a fan of) but with the older Garrett 5-bolt flange. The newest Garretts and BW EFR dump the IWG into the housings V-band flange. PTuning uses an external wastegate and offers a downpipe that includes a merge of the dump tube. They also ship with an older Garrett turbo.
Both of those kits tuck the turbo under the manifold keeping a lot of the heat out of the engine compartment and making plumbing and installing the downpipe easier.
I'd be a fan of the BW EFR for this application because of the internal wastegate, integrated BOV on the compressor housing, mount for the included 3-port WG solenoid on compressor housing, availability of compressor housings with 90° (from BW) or swivel (aftermarket) compressor housings, and the lightweight turbine wheel. To me, less plumbing is always an advantage.
The trick with all the turbos in this application is the efficiency of the compressor at the low pressure-ratios of a high-compression turbo engine on pump gas. OEM turbos are designed for that (now usually with direct injection and sometimes variable turbine housing vanes). Aftermarket turbos, less so.

The car is not daily driven but I do want it to be comfortable. I saw SOS had 11.5 and 8.5 flywheels, so I have options there.
I've had some pretty poor experiences with e cutouts, but it's been years since i've had one so perhaps they are better now (or I just did it poorly). I had one on a turbo SE-R I built years back and overtime it failed (like 1.5 years). Any recommendations on a solid one? I'd consider it.
