whats going on... this weekend im going to purchase skunk2 stage 2 cams and skunk2 valvesprings & retainers...i have a 2nd gen jdm b16a with 10.4 compression., is that compression decent for the cams??? or should i add a thicker headgasket to bump it up alittle bit

 

10.4:1 is kinda on the low side for the stage2's. look into a "thinner" headgasket to raise the compression.

 

bump it up to at least 11...if not go with the stage1's

 

ctr cams

 

you could gain another 0.2 CR with high CR valves if they aren't uprated already. Thinner Gasket, both would increase CR to around 10.8:1 without milling

 

o okay so do u think with the 10.8:1 compression it could handle the stage 2 cams ? also would i need to get aftermarket cam gears?

just strip 2 layers off your oem headgasket. That'll bump it up to 11

 

u serious ? ^

 

bump

 

High lift cams "like" high compression, but that doesn't mean they need it to run. I had Skunk2 Stage 2's in my 10.1 GSR, and it made 180/130 on a Dynojet. All bolt ons. High comp = higher numbers.

 

mill the head .030 s2s2 cams ******* love comp

 

Chances are you'll get some top power from them but you'll loose other places.

B16 does not like big cams, skunk 2 stg2 have itake valve closing at 49 ABDC, what this means is that you'll leak a lot of your already low compression away (known as dynamic CR if you care).

Ideally you are looking at 11.5:1 static comp on B18C for these cams and your B16 is different world compared to this.
B16 I would not put these cams before 12:1 staticCR at least, but hey that is just mu opinion...

Unless you want your car to putter around until it hits 7000+ I would suggest you look into CTR cams (which might be slight overcam anyway). You know what you get, quality is gueranteed and still gives you room to grow in the future...

 

good info

 

just get the s2s2's, you know you will eventually be doing more work to your motor. Why buy ctr's now, to just have them removed down the road when you build your block or do headwork? s2s2

he's right... i'd get the s2s2 also... sooner or later your gonna want more power.

 

S2S2's (blox B's) made more power over S2S1's on a friends 9:1 compression turbo motor. The gains might have been higher with more compression, but they still made more power.
