Hi guys....

I'm new on this forum and i just need some advice/opinions from you guys that have had first hand experience with these Cams as not many guys from South Africa have these.

I have a stock b16A5 motor with a 57mm exhaust & 4-2-1 header as a daily drive. I've been lookin' at getting a good set of cams in my car & have narrowed my search down between BC4 cams & BC3+ cams.
To get these in South Africa is flippin' rare as the import costs are very high.

My goal is to get around 120 -130Kw (163 - 176 whp) from my dinky lil' b16. Would i be able to hit this goal power. the car is rated at 110Kw (149whp) in its current state from my tuner.

I'm getting the BC4's at half the price of new BC3's because they're used parts.
If i go BC4's i know i need to upgrade the valvetrain & bump the compression up to really make these Cams shine. Are these cams too harsh for a daily drive?

The BC3+'s are pretty much bolt on but will these cams make me hit my target output?

Please feel free to leave advice on what needs to be done to my b16 with either of these setups. Thanks
