Just so people understand what this is about YOU MUST MATCH YOUR CAMS to your inlet and exhaust manifolds or you will not get the full benefits from the cams,and Adrain and myself both know how well this head works with its valve job.

Ah yes, very good point....

Time for better pipes too

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.
