Hi guys. A topic to show you my swap which is allmost finished.
The original engine of my GT86 was broken. So i bought a wrx 2015 FA20DIT (new).

Here are the mods which are finished:
- exhaust towards driver side
- FMIC (same volume as WRX TMIC)
- a complete intake manifold to integrate dual injector ports
- GT86 PI injectors + FA20DIT DI injectors
- lambdas, maf moved
- evaporative valve removed
- intake depressure + bypass for mastervac brakes

Remaining work : engine tuning.
- i ve kept the GT86 wiring (almost plug n play with FA20DIT sensors)
- the engine starts but doesn t sounds well even with playing on the tune (100% PI, 100% DI, lean, rich...)
- tactrix OP2 + ecuflash write/read sucessfull

I ve seen WRX2015 roms and ignition tables (and AVCS) are very différent from GT86. So i m thinking about buying a complete WRX2015 ECM + keys.
