So after many months of research the engine build is finally underway.
I settled on the following

Ej207 semi closed deck case halves
2014 sti 2.5L crank for 2.1L cap
Manley rods
Weisco pistons
GDB heads with 272 kelford cams, new springs and retainers
Acl bearings
Arp 625 studs
New cam gears and belt
New gaskets

This will be mated to the following that already exists on car (V6 STi)

Autronic ecu
UEL headers (wrapped)
Process west top mount
Autronic ecu
Standard intake (stock look for mr po po)
3"dump pipe and 3" dump pipe
Sti 6 speed (long ratio)

Only thing i cant yet settle on is turbo.
Torn between blouch 20g xtr or a stock fit atp gt3071r

Im aiming for 370whp+ on 98 ron (or a high ten second pass)

I believe the top mount will be my limiting factor.

Also what injectors do people recomend for the above.
