Difference between Spec A's, B's, and C's?
I hear all this talk about Toda Spec A's, B's, and C's. They're cams, right? But what's the difference among them and what is the respective benefit to each. Involved question, I'm sure, but you're the guys to ask. Thanks.
They all have different amounts of lift and duration
Spec A - Street cams
Spec B - Mild (rough idle, top end power, etc)
Spec C - More Agressive (like B's but / more duration = more top end, etc)
hope this helps a bit
I'm sure others will go into detail

If you have a type-R and don't want to modify a TON of things to make your car run right, just get JUN Type 2's.
Drop them right in, and even with minimul to no tuning, they are going to make power.
JUN 2= best cams for stock Type-R's on a budget.

I'd beg to differ, ImportReview. But then again, my census for comparison is not exactly there. I have only seen one dyno sheet of JUN 2's and it did not impress me. For the best street ITR cams I would recommend Spec A cams.
Show me what these Jun 2's got!!

T: Please call JUN.
Its hard to talk about anything except Toda on this particular board. I notice alot of people are biased or favor Toda for some reason. Maybe I deserve it because I like JUN cams and favor them. I just tell it like it is though. People on here know that by now. LOL
But I stand by the specs and the Dyno on this one. Jun 2's are going to give you more peak power than Toda A's..on a stock head.
Especially on a stock head. I don't want to argue with you Mike. I think posting up a few dyno sheets would generate a flame war. People at this point, are not going to change their minds. I want to keep it peacefull with you, could you please offer some insight to exactly why Toda A's would make more power?
Just having or seeing a dynochart or 2 with those cams really is not proof. I have seen a few motors with Type-R cams at 216 Hp naturally aspirated. That doesn't mean that R cams are better than JUN 3's because I saw a few JUN 3 cams with similar mods at 214 HP.
Heck I heard a company made 265 WHP with their cams, and I tried them VS JUN 3's and they made 10 HP less. This doesn't nec. mean that if they use JUN 3's in that 265 WHP motor, they will make 275. This is an example..
Cams are a very complicated matter and when you go into ported heads, you really don't know what cam will be the best unless they ported the head to those exact cams.
I got a head from Endyn that was suppossedly ported to Type-R cams. Endyn stressed to me that any other cam besides Type-R would be a loss. I was told by that company that JUN 3's would lose power because it had too much duration. That the head flowed too much air for the JUN 3's. That is what they said.
So, against that companies wishes, I put in JUN 3's. They made 14 HP more at the wheels that the Type-R cams, that were suppossedly mated to that head by the porting.
I guess what I am trying to say is that with stock heads, different cam profiles are going to be pretty predictable in terms of performance. And repeatable.
But with ported heads, you can't take anyones word for it and just have to try it.

gah!
don't take it outside! We wanna watch!
Seriously, we're all adults here - share the facts please.
Check mail, Sparky.

i've noticed that too, everyone here is partial to Toda's...well, most everyone

Mention the word Toda and people come out the woodwork praising to Allah that they are the best cam in the world.. To say most people are partial to Toda on this board is an understatement.
Toda's are reliable, good quality, put down good HP, etc. Why go with something that is unproven or that only a handful of people have dyno tested and/or had success with?
damn....i was actually thinking about dumping my R cams for some Toda A's or JUN's.
it is true peeps here are biased. mention Crower or Skunk2 and everyone(except FAST94GSR
) yells TODA!!
i know all cars are gonna respond differently. so dyno graphs really dont mean too much to me. ive too many where toda will out perform, and then i see some where JUN is king.the way i see it is if i see some car haulin *** and i ask what he has, it makes me want to get the same ones. so i guess word of mouth or what i experience is worth more to me. because the more i hear about a certain product, the more i want to . Am i the only one?

I don't really care who makes a particular cam, as long as it makes good power in the right part of the powerband.
I have seen time and time again, that Toda Spec A cams offer awesome power gains over stock in a *fairly* stock setup. Spec B's on the other hand, I am not a fan of. Personally, I had a real hard time getting decent power out of them on my friend's car. He had all the "recommended modifications" as well, and he was still slightly under 200whp. Yes, they pull hard up top, but I just don't like them.
This doesn't mean that I am talking **** to people who run the Spec B's. If you do, and you love them, and they make awesome power... GREAT. You had better luck than I. Maybe it takes more experience to tune them, I don't know.
Skunk2 cams are excellent. I have NEVER seen a GSR with stock compression put down 180 and 130 to the wheels until one of my friends put Skunk2 cams in his GSR. I would be interested in seeing these cams in action on a highly modified motor. But again, like the Jun2 cams... I have little to no experience with these cams.
I have dyno'd all three Crower grinds for VTEC engines, and I was not very impressed. Out of the three, I would have th say their "Road Race" grind is the best overall. But in all honesty, I would choose OEM ITR cams over these Crowers.
I don't want this post to be a flame war, but rather people just sharing information with what they have. Post dyno sheets if you have them, and post engine modifications as well.
Let's have some good clean fun(although it may be hard with Jun being the black sheep among Todas). I am VERY interested in seeing JUN results.

Crane Roller rockers...5,000-13,000 rpms power band, 12.00mm lift and 266 deg of duration.

I wonder what kind of gains can actually be had out of those things. I'm sure the fact that the rockers weigh 52% less helps.
Also, there is way less fricition. I won't be the guinea pig though!

I think I will just stand on the sideline on this one.
I think people knwo what i think, I must have posted 20 charts on cam comparisons in the past.
I like the cams in this order:
#1 Jun 3
#2 Jun 2
#3 Skunk 2
#4 CTR
Those rating include performance for the money, how well they work overall, and how well they work in a variety of applications.
Toda Spec C would for sure be amoung the best cams....thats if they didn't cost you your left eye or left leg. They are VERY expensive to get to run right...you need alot of mods to get what you want out of them.
Not so with JUN cams. Or Type-R cams, Or the Skunk 2 cams.
I am going to have to do a JUN 2 VS Skunk 2 test...
because they are very similar.
My essay ends there. I don't want to start anything insane. This issue has been covered.
Mike K...I am reading your e-mail and will reply. Good stuff Mike.
YOu argue intelligently.
