these are the specs on both cams:
Spoon INT:11.53,256@1mm EXT:11.13,245@1mm
Skunk INT:11.58,252@1mm EXT:10.90,249@1mm
ok now for a b18c1 with 11.5:1 comp. which cam is gonna give me better mid to high end performance or are they to close in spec to even be able to notice. I can get them for about the same price so thats not an issue. the car is daily driven and raced on the weekends.
thanks for the help

 

I don't know about those two choices, but I have a JDM b18c with 11:1 CR and skunk2 stage2 cams, and all I have to say is Yeah baby!!!!

 

it would appear that the Spoon cams would have more lift/duration than the SK1 cams... with that compression, you'd be better off running SKII cams.... but to answer your ?- Spoon might win the race

 

Can't go wrong with the Skunks...

Get what works...

 

Get a bigger cam.

 

If you had to choose between those two. id go with spoon.

Cant go wrong with oem quality.

so you think i have enough compression to get good use out of a bigger cam?
with bigger cams comes alot more expense(valve springs, retainners) will i notice it enough for the extra cost?
do you recommend any?

 

Gee, I wonder what cams I like better.

Skunk2

 

you guys that are saying SK2 why? what is the reasoning? I'm looking only at lift/duration and his compression. The Spoon cams are more suited for the application.. so why are you saying SK2? I'm not hatin' just wanting to know the rationale

OK, how about between Spoon, Skunk2, and Toda As?

Skunk2 cams have a good rep. They're CARB legal for those livin in California. They make good power mid/high end, and past the stock redline. It works perfectly fine on your STOCK valvetrain without a problem.

Those are some things that make the Skunk2 cams a good choice.

Now I'm not saying Spoon and Toda cams are wack. All three are respectable companies.

How are you making your calculations? I'd be intrested in hearing how to calculate the ideal duration/lift with your compression numbers.

 

Realistically, he should be running JUN III, SK2II or the like with that compression. I usually reccomend 11.5-13:1 compression for those cams. I'm taking that theory and applying it to the two cams listed0 instead of saying go bigger- and that is how I come up with the rationale. Now, that's not to say that the SK2I cams aren't good cams, I'd just use those profiles for 10.0-11:4 compression. Why? Because if you're running a high profile cam with low compression- I love to do this- you actually LOSE that compression by .4 (I believe) Now, if you have a high comp motor and you run a low profile cam in there, you aren't going to see super gains because the cams won't be effectivly using that compression. Instead your compression will hurt the performance a little. I'm not saying you won't see gains, but with a higher comp motor, it is my belief that you can run a bigger cam- effectively lowering your comp- on the street and be safer with the pump fuels. I hope that kind of makes sense... I've had a few so my explanation might be a litte fuzzy.... LMK if it doesn't

 

ok here are the specs of the mild cams

skunk2 stage 1: int 252 dur/ 11.5 lift exh 249 dur/10.8 lift
spoon sports: int 256 dur/ 11.5 lift exh 245 dur/11.1 lift
toda a's: int 290 dur/ 11.6 lift exh 280 dur/11.2 lift
jun type 1: int 265 dur/ 10.9 lift exh 268 dur/10.0 lift

question is which is better for mild setups and why? toda A's seem to be the most agressive of the bunch with wild duration

wow you really think that i have enough compression to get good numbers with the jun III's. i always thought that the magic number for those cams was 12:1 ??

 

- Stage I
INTAKE lift- 11.58 mm, duration 252 @ 1mm
EXHAUST lift - 10.8 mm, duration 249 @1mm

- Spoon
INTAKE lift - 11.53 mm, duration 256 @1mm
EXHAUST lift - 11.13 mm, duration 245 @1mm

-Toda Spec A
INTAKE lift - 11.6 mm,duration 250 @1mm
EXHAUST lift - 11.2mm, duration 240 @1mm


Toda doesn't advertise their cam specs at @1mm, which is why you may think it has alot more duration then it actually does.

The stage 1's own the toda a's in duration. For 11.5:01 compression, i think stage 1's would be perfect. With stage 2's in there, you'd be left with something to desire. On a street car, the stage 1's are perfect. CARB exempt, stock idle, mildly aggressive. You don't necessarily need big cams to make power. Something that people always seem to neglect is headwork. If your head can't flow, then your "big cams" are useless.

In the beginning of summer, i had toda b's in my gsr w/stock gsr head. It made 194.9 on the dynapack. Mid way through summer, I shredded a timing belt and bent all my valves. While the head was out, i got a street competition head work package from joe alaniz. I swapped my cams out for skunk2 stage 1's because i wanted some more reliability. When tunning day came, i was hoping to at least keep the same amount of top end power as my toda b's. However, to my surprise, i made 15 more peak hp then my toda's! From 6000 up until 8500, i absolutely pissed all over my old set up. The toda b's still made more midrange then my skunk2 stage 1s, but for the top end gain i got, i think it was worth it.

Not many people i know run spoon cams because they're expensive, so i can't really comment on that. Just wanted to shed some light on the stage 1's.
