Soon bro!
The Synergy 20G. Pretty decent turbo for the money. If i don't do that i'll be saving for the new BorgWarner EFR 7163 turbo. Crazy hybrid turbo that will kick down serious power but spools extremely fast, almost stock like. Only problem is you'll need Full Race up pipe and downpipe which is added money.
Pump vs E85
Pump and E85 compared with a typical Stage 2 08+ STI
Damn near stock turbo spool with nearly 200whp more by redline... not too shaby

Car: 2008 Subaru Impreza WRX STi
Tuner: Me, Paul Leung of YimiSport Tuning
Dyno Info: Dynojet 424X
Ambient Temp: 95*F
Elevation: about 1300' ASL
Transmission: Stock 6MT
Gear: 4th
Peak HP at RPM: 440whp @ 5900rpm (E85). 350whp @ 5900rpm (CA 91 octane)
Peak Torque at RPM: 443ft/lbs @ 3600rpm (E85). 353ft/lbs @3600rpm (CA 91 octane)
Baseline hp/tq for a stock on same dyno: 230HP/255tq - 2008 STi
Target Boost: 25 PSI (E85), 22 PSI (91 Octane)
Target AFR: 12:1 (gasoline scale on E85), 10.9:1 on 91 octane
Fuel: E85 and CA 91 octane pump gas
Mods:
- Full-Race uppipe and catted downpipe to locate a Borg Warner EFR7163 (2013 release turbo, one of only a handful that have made their way out in to the world) in stock location. Ready to bolt up to all OEM or aftermarket parts that will fit the stock turbo (inlets, TMIC's, FMIC's etc...)
- Fujitsubo Legalis R catback (with the 2.5" taper intact)
- Custom YimiSport 73mm CAI
- Custom YimiSport FPR kit
- APS turbo inlet pipe
- Grimmspeed hybrid EBCS/MBC boost control
- Deatschwerks 1000cc injectors
- Synergy 300lph fuel pump
- Cobb AP
The narrative that no one cares about:
Stock motor (60k miles), stock TMIC and stock exhaust manifold. Basically just enough mods to supply enough fuel, sample the incoming air and get it out the back of the car as quietly and cleanly as possible
Every so often a turbo company introduces a product that "spools like small turbo X, but make power like BIG turbo Y". Physics being the b!tch that it is, has usually proven such claims to be more hype than reality So when Geoff from Full-Race told me about a new turbo that would spool like a turbo 10lbs/min smaller than it's rated flow, my interest was piqued, but my BS meter was similarly pegged. I'll let you guys be the judge, but I think even on my less than fully supported test platform, Borg Warner and Full-Race have come pretty close to their claim.
I have always wanted to have a Subaru that made 500wtq before 4000rpm and still made over 450whp. I'm not quite there yet, but with a couple more bolt-on mods I can easily see it happening even on the stock block. In the mean time, I've been enjoying one hell of a broad powerband and nearly instantaneous boost recover all in a damn near stock appearing packag

I was lookong at that exact same setup im debateing on a couple turbis myself i was looking at the synergy 20g 3" inlet one which is actually a 601 turbo. Or the atp gtx3071 or 76 or just wait for that full race kit. But that kit looks really good

My buddy has a GTX3071 and puts out 349whp/350tq on pump 91 with a built motor. On E85 he has 440hp and 470wtq. It's a good turbo but i think he doesn't hit full boost until like 4600rpm or a tad later. Synergy makes some good stuff for a decent amount of money which is why i'm considering it. Honestly i'll probably end up with a 20G because i know the EFR kit is going to cost an arm and a leg since you will need the turbo, uppipe, and downpipe but i still want it for earlier spool.
