BC V2 264/264 cams

[Shift_Dr1ft]

Hey guys, I have researched but I didnt get the results I want. So I am in the market for some crower 264/264 V2 street cams for my N/A s13 (KA). From what I heard these are plug and play. Since there is a higher lift will I pass smog? Because I read somewhere that if you change the cams into higher duration it will affect smog. My second question is how much rwhp will I gain from these cams. Anyone running these cams and is satisfy with them? I have seen some dyno charts but they were on turboed cars. How are the power range for these cams? Thanks a lot guys.

Also curious. Actually someone suggest cams for a DD that will see HPDEs and other track stuff.

Thats a big cam for an N/A setup imo.

Too much for a DD? What about with machined SOHC pistons?

yeah, I've always thought of 264 as entry turbo size cams, I would consider more along the lines of 256 (don't know if bc makes them) but hp at the wheels wouldn't be more than 10 if that, on an engine like the KA most people don't think that cams are even worth it unless you're going to fully build the motor

p.s. I have 264's on my s14sr and they are pretty high quality, never drove on stock cams though so I cant say if there was any real difference in power

People have run the 264's(v2) pre-turbo just fine picking up some power also. with all increased duration some tq is lost in the low rpm but the breathing on the top end makes a big difference.

I would have to think these would affect our emissions and you don't have a hope to pass without a tune. I dunno what your states smog test involves so I can't guaranty you will ever pass.

Even though they claim not to need upgraded springs. I think this is more of a marketing ploy that you won't get coil bind or something. I think you will have some float and I question the long term.

Anyone run 264's on a T28? You guys think those cams are mismatched for the turbo?

[babowc]

I'll be running 264 on a Z31 T3, if that matters.

The V2 has the dizzy drive because its made for altimas, you'll have to cut that off.
easily done with a saw.. did mine today.

You did what? :tweak:

BC cams had a distributor gear for FWD KA's.

RWD ka's didnt use them so you would have to cut them off with a dremel tool or saw, which is retarded because BC just released set of cams for both FWD and RWD ka's to save costs i guess...

[babowc]

^probably.

it's no big deal.. just cut it off and done.
it's pretty fucking gay I paid ~$300 for a set of cams and I had to take a hacksaw to it, but oh well...

Altima Distributor runs off the key slot on the end on the cam...

Yeah, you have to cut that off on a RWD KA. AMS/Turbo240 had a writeup on how to do it.

too big? lmao. thats how na cars make power. its not like they have a snail pushing in more air. i have the 264 cams in my s14 . i also have some other mods. im actually going to do some 304 duration cams soon. building a 12.5 to 1 bottom end. my car made 183 to the wheels. i also degreed the cams using the jwt cam gears. deffinatly worth 150 bucks. honestly i didnt feel a whole lot from those cams until i degreed them whith the gears.

On an SR, yea, the T28 is out of breath with just the stock cams, so adding 264s on top won't gain you much. To me it felt like I did gain some HP up top, and the MAF voltage went up a little bit towards redline, but it wasn't a huge difference. Felt like less difference than adding 1 psi of boost.

This makes me want to go 272 just for the idle! :aw:

What? No its not.

im running crower 272's on my sr with a gt32r and it really helps me spool that monster up, i mean my motors fully built, ported and pollished head valves valve springs retainters, the works so... its probly everything in conjunction with eachother, but i was running the 264's with the same setup and i can definitally feel the difference between the two

How is driving around in traffic? I've always been under the impression that high lift/high duration cams = stuttering, hardly any power in stop and go traffic. I'd imagine a lower compression 2 liter would be worse than a higher compression (assuming aftermarket pistons) 2.4 liter. Input? :bigok:

[sunnys14]

I felt a noticeable low end loss on my KA-T going from stock 232/232 cams to 248/248 cams. I'd imagine a bigger low end loss going to 264/264, but im sure some cam gears with correct timing can make up for the low end loss.

If you buy these Cams, make sure you know how to set valve clearances and expect to have a few days of down time if you have to order in different size shims for the cam buckets, We had a few customers with problems when not properly shimming the buckets and having tolerances that were too tight and too loose. Problems that were most likely do to coil bind. Also get the spring and retainer kit. I really don't feel comfortable about running a bigger cam on stock springs that most have seen over 100K in their abused lifetimes some more...

the whole spending 300$ on some cams then having to take a grinder or saw to them did not sit very well with me or my customers. I wish they would have taken a few extra minutes on the RWD sets and just did that machining for their customers. I Think this sways a few people from even trying their products.
