BC specIV vs. Scunk2 stage 2 for B20/GSR? i'll be runnin 11:5 or 12:1 comp. and i'd like to keep the stock idle characteristics. will be tuning on dynojet. my goil is to make 220WHP hanging around 9000+RPMs. all positive input is welcome. thx.

 

Same vtec lobes. BC4's have larger primaries but are easily streetable. Mine idled at about 1100 with a bit of lumpiness. Even without tuning, they will both idle just fine. That's the advantage of variable valve timing. Now if you had a non-vtec head, your idle would dearly suffer with those vtec sized lobes.

 

thx for the info bambam. any other input from HT

 

if your looking for stock or close to stock idle get the skunk2 stage2's.

You ever run BC4's? They idle fine.

 

i have bc4's in my motor. im just saying skunk2 stage2's have stock or close to stock primaries.

 

ok the cam caricteristics i want. i want a close to stock primary with a hard cross-over to the vtec lobes. if i wont power i'll winde it past 5'800rpm. but for normal (not beating the **** out off my newly built motor) driving i'd like close to stock fuel economy.

 

bump

Having a hard crossover has no advantages. This is a ricer mentality.

 

your kinda rite. but what i mean buy that is i'd rather have normal OE characteristics in my primary and all out performance in my secondary. maybe not the best idea if i wana get 220whp.

The smaller the primary, the more valvetrain wear that will occur when you do decide to cross into vtec.

 

cam chose is so complex
