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!)
