I got a b16a with portflow springs and oem retainers and ctr cams. On the dyno i only reved to 9K but it seemed like it wanted to keep making power. What setups are you guys running and any recommendations in what to upgrade to?

81x77 b16a, sleaved, manley rods, cp pistons gt30r, victor x fullrace manifold.

TIA

 

My stock port B16 head made peak power at 9800 rpm on nitrous with crower 3's. and my turbo B16 stock ports made peak power at 9500 rpm with Gsr cams. it just wants to flow.
I'd suggest upgrading the retainers. other than that, it seems like a solid setup
