1: Do I need to add head shims?
2: manifold/tuned pipe choice? Here in Hong Kong I can't get your tuned pipe set from shops which I am sure is perfect match to your engine. We have OS and Nova here. Because the track is not big, I am looking for acceleration than top end performance.

Thanks you

I only run VS04 with original head shim with 25%, in both track TRC and ACO no additional 0.1mm shim is needed, the power band is more than enough and no need to over-tune the engine.
I run Max 90-+90 manifold with One 2163 pipe, I've tried Max manifold with OS pipe but the fuel consumption was high.
