Thank you for your inputs Master Jedi's!

So for my current engine to surpass the 140kw mark the following items need to be addressed:

1. Aftermarket Camshafts (Rocket Motorsports M22x)

2. Aftermarket Valve springs (Rocket SL)

3. Clip-On Retainers

4. Better Header (Recommendation?)

5. Re-tune the Apexi ECU to utilize the above mentioned upgrades.

Will the OEM Fuel Injectors & Fuel Pump be sufficient to feed this newfound thirst? (I'm guesstimating NOT lol!)

5. Bin the Apexi & replace it with an S300 or Neptune RTP (with Moates Demon)
It'll make about 4kw more everywhere... (not sure why)
nb: Of course you can keep using the Apexi as you've got it & it works

Probably make even more with a VIPEC or LINK G4 too... (great timing control on these)

Add some RDX injectors with a Aeromotive fuel pump with the above tuning solutions and I will love you long time.
PS I have the injector kits in stock for B series and fuel pumps can be had same day from a Sydnet based supplier.
