Recent results of my SC42 billet. It is not the latest version of the SC42+ but the standard billet SC42 turbo (with black casing). I had this upgraded with ceramic bearings, metal bearing cages and with an uprated 1.2bar actuator.
Made 456bhp Not bad from a 420bhp rated turbo. Car is an animal now.
Supporting mods:
Forged 2014 VA SCDB 2.5 Engine.
SC42 billet custom rebuild by Turbo Dynamics JE forged pistons Manley piston rods ACL race bearings New genuine 2.5 Subaru crankshaft RCM head studs RCM stopper head gaskets RCM oil pump kit RCM timing belt kit TGV delete Secondary air system delete Exedy pink box clutch
AS Performance ultra-light flywheel Genuine MAC 3 port boost solenoid RCM 340 fuel pump Uprated Perrin oil cooler setup
Forge turbo blanket RCM 3 bolt GT spec stainless steel headers fully DEI wrapped. Harvey Smith trick up-pipe to suit SC42 fully DEI wrapped Invidia divorced 3" decat downpipe
Invidia full 3" Q300 stainless exhaust Perrin silicone turbo inlet pipe Tial Q 50mm BOV with 11 PSI spring Injector Dynamics ID1050 injectors flow matched including wiring adaptors Perrin ASM-FUL-300 fuel pressure regulator kit NGK heat 7 plugs K&N Typhoon 69-8007TWR induction kit Fuelab fuel pressure gauge, fittings and fuel pipe to go with Perrin FPR.
Process west 4" FMIC setup, modified with Tial Q BOV port
Final fitment and mapping y Enginetuner. Mapped on EcuTek Racerom.
Sure there's more I've forgotten. Most parts purchased with future power increase in mind which is why a lot is over-specified for this power level. Engine will either get another rebuild to CDB 2.5 or 2.35 next.

Really impressive. Did you have to go MAFless? I have a hybrid VF48 with larger compressor wheel on a ball bearing which was limited by the MAF.
Thanks

Nope, still running MAF. Was prepared to go mafless but Martyn at Enginetuner said it's only needed at much higher levels and car will drive better with MAF. So long as you have a decent induction system the MAF isn't restrictive.
