Hi, im running a B16 with DTR pistons ,P&P head, 5anglevalve job,flat valves ,VibrantJ spec4-2-1 header,DIY ITB 48mm, currently running CTR cams, does i can run BC4 on mi set up or you recomend BC3+, im reving it to 9k so i can take advantage of the 4's but clearences(piston to valve ) and 3+ dont make power over 7900 if im correct, what should i do???Can someone tell me?

 

the BC4's will carry power higher then the +3's. they start to fall off abotu 8200 i think and the BC4's keep claiming..depending on your set up...i have a set of BC4's if interested

the 4's are too big for the 16. i'd say stick with the 3+'s. they will still pull up high with its short storke & the ITB's. what's your c.r.? i'd assume if you used a set of 4's in the 16, you'll have to rev above 9K to peak out. you need make power under the curve, especially with the torqueless wonder. just my .02.
