I just bought a jrsc street kit. I plan on swapping the pulley out for the 3.8 pulley before i put it in. My question is how will skunk 2 stage 2 n/a cams work with this setup? I have em but they're not in my car yet. Any info will help.. thanks.

i had BC stage 2 cams on my JRSC setup before and it didnt gain much at all. i was losing psi and power. when i switch stock cams it made more power and psi all around.

thanks for the cam info. here's my setup for the near future. Any advice or opinions will help thanks.

jrsc (street kit) 3.8 pulley coming soon.

thinking about 650cc injectors
might need a clutch but was wondering how much power the stock clutch can handle?

Did you get it tuned with the new cams??? I put the BC stage2 F/I cams in mine and love them. After the final tune I lost about 2psi of boost but made nearly 20 HP. I made more torque but forget the numbers, somewhere in the neighborhood of 10 lb/tf.

I didn't make much off the bc cams either. Was raving to 8700 rpms thouh lol

ill be doing the skunk2 stage 2's and supertech single springs on stock retainers (skunk2 springs are TOOOO stiff) and im curious about my results. im not going to rev past 7700 so im hoping the setup takes liking to the new sticks and makes some more powa

people, people, Hold up a minute. I would advise everyone on this thread to read the post on all the forums about the junk2 cams. I personally have a friend on this forum who had the junk2 stage 2 cams, and he toasted his motor in 2 months maybe less. those cams jump the teeth and that was the end of a 270whp ep3 k frank. please do more research before you guys use those cams. check out k20a.org

my skunk2 cams also made my motor blow, had modified tensioner and supertech dual springs and retainers. Only took 1000 miles before it took a shit

Where are you getting your cars tuned? I conservatively capped my redline at 7,500 rpm because my EP is my daily driver and still made good gains from the cams.

I only gained about 10whp with the 4.0 pulley on my a3 with the bc stage 2 cams. When i did the 3.8 pulley and meth I saw over 20whp gains with the cams. I was the fastest a3 JRSC on this site till 04ep3hatch came along!

ok ill say this, these cams cannot make your motor blow. the biggest thing that PROBABLY had to do with it was the dual springs, that is such an increased pressure on the chain, tensioner, and guides its not even funny. there is no need to go that high on a daily driven car, i would only use duals on a race setup revving to 10K. what stage cams did you have? was your tuner knowledgable? and did you abuse the car

RHCP0801
02-15-2011, 07:54 PM
i had stage 3 cams, yea he was knowledgeable and tuned many k cars, no i didnt abuse the car at all. I never abuse it and it just shut off on me when I was leaving a stop sign in 2nd gear at like 10mph

I'm hoping to see some gains with the Skunk2 Stage 1s with my JRSC-R setup when I get dynotuned these next coming days.

id be partial to beleiving the dual springs put so much tension on the chain that even the modified tensioner couldnt hold up. the skunk2's only downfall is the fasramp. it snaps the valve open so the engine can really breath, but like talon said in another post that the timing belt on older b-series absorbs the shock from it, the kseries have nothing to absorb it

GIGGIDY! whens the dyno im interested as well!

Same set up as you with Stage 1 cams sitting in the box.
Looking forward to your numbers!

yea but you cant use single spring retainers with stage 3 cams, it was a combination of the fast ramps on the cams and the chain just being stressed

im still waiting to get my jrsc in and tuned before i put my cams in. 2nd week of march is when its goin in and getting tuned. Im gonna wait till i'm tuned to put my cams in or maybe sell em to get water/meth. I have z3 spings, ill talk to my tuner before i go with this setup. I want to hear some more info about this too.

Ur gona have to get re tuned for the cams. If u have em u might as well do it all at once

Ya true. I just don't want to waste my time with em if I'm not going to see any gains.

I currently have Skunk2 stage 1s in my car and planning on going JRSC-R with 3.8 pulley. Really interested in what you numbers are going to be, let us know!

I was wondering about this? I have the street kit and plan on swapping the pulley. Do i need to do the map sensor relocation? I actually emailed jackson racing about this and they said i didn't have to do it. Can anybody give me some info on this please? thanks.

i dont want to go crazy with the A3 i dont think, i want to keep it real oem with driveability so i might just get a new cam from chris at xenocron, he has one laying around. but i dunno as well. i might go ivtec killer to

Aww man. I think the Stg 2's would be safer than going with the vtec killer setup. Just grab a hybrid racing chain tensioner and a set of supertech valve spring and you should be good to go.

I blew my A3 a fews ago and am in the process of getting a K24A1 which will get all my current mods along with the Crower Stg 2's and my AIS meth kit. Good luck to you! My motor died from a mechanical over rev :facepalm:

Did you upgrade you springs/retainers with the BC cams? I'm shopping for valve train and don't want to swap to springs that are too stiff, it'll be for a K24A1.

So I got dynotuned tonight. Gained 7hp and 11 pounds of torque at 11.3 peak PSI. Tuner said the car makes power quicker throughout the midrange but falls off quicker at high end. I'll post some graphs once I scan them.

yea. bought BC springs and retainers

ok soo n/a cams do work ok but you lose a little psi or boost but the hp makes up for that cool cool...:pop2:

still not understanding why people put a N/A cam on a boosted car.
You have to look for a cam that minimizes overlap.

Yes, lift and duration. It's why I'm on OEM Cams. ITR intake and '04 a2 exhaust cam. Midrange through the roof and still pulling power at 9k rpm. Honda FTW!

Sorry, Skunk 2 = junk IMHO.

Because it has been proven to work on two lobe applications. The hasport crx picked up 20+ when they added skunk2 stage II cams to a jrsc k24a4. Beechstreet just picked up 7hp and 11tq with stage I cams. However, when it comes to 3 lobe, I haven't seen any proof that n/a cams work well with a supercharger, but they are being used in some applications turbocharged on k20a.org putting down 600+
