Quick question here. I am going to be running the following:

Skunk2 Stage II cams, valves, springs, retainers, Type-S Pistons, Skunk2 Intake Manifold, 2.5" exhaust, modified DC Sports header.

Where should I set my VTEC crossover? Right now with the ECU I'm running, it's hitting at 5500 RPM, which feels way too high. Also, will a dyno-tuned chipped ECU handle this setup adequately?

Ye Ol' Dyno will show you the way
I think to get the most out of that setup would be to run a Hondata...but thats just me...I always do things overkill

 

oh and by the way, with jun cams, vtec engangement will be RAISED to atleast 5900 perhaps higher. The idle lobe alone is bigger than the stock vtec lobe, lol its intense.

 

Anyone have any experiance with S2 Stage 1's? Im considering those after a header and vafc, and possiblely Type-S pistons. From what i've gathered, it increases the powerband all throught the rev range up to the stock redline, as opposed to the stock cams where they start dropping off around 7k. Is this correct guys? Point me to any dynos that you know of, thanks.

 

crower 2's w/completely stock head and bottom.

195/150... sorry no before stats, everything was done all at once.

should be good to see,

were 284 with 240 duration at 0.050 and 11.2mm lift

Anyone know how JUN cams will work with stock JDM 10.6 pistons? I can't afford the Type-S install. I guess it's close to the same as Crower Stage III's VTEC duration/lift.

Well, i would think that it would work fine, but bumping up the compression will definatly yeild more horsepower from those high-lift cams.

 

car will run fine with stock pistons and jun cams, thats how im runnin until i go jun bottom end

 

Jun cams and valvetrain hit a 190 UNTUNED basline run. Vtec crossover is at 6000 RPM's

NEWSFLASH:: You cannot use the secondaries with jun cams!!!!!!!

why cant the stock operating intake work with jun cams?
it worked fine for me.

if you didnt have the secondaries open then the lack of air flow would choke the cams in vtec.

and my vtec crossover is stock 4900. and that is on the JUN ecu. you just have to have very very good exhaust flow so they wont bog or flutter.

i make 220 whp on a mustang dyno. totally untuned! i dont have any back to back cam runs though. jun cams.

 

stock vtec crossover is 5200.

Soon as i cap my secondaries for them operate correctly, car stalls. I leave them open, car idles perfect. I have a good exhuast system and thats the only thing ive narrowed it down to.

The idle lobe on the jun cam, is bigger than the stock vtec lobem thats saying something. everyone i know with jun cams has their vtec crossover between 5800 and 6200 including a jun b16 motor with the jun ecu. SO i dont know where you got your jun ecu, or who tuned your car, but

To make that kind of HP on a mustang dyno is crazy, he's doing something right, not wrong

 

JDM H22, AEM CAI, DC header, Thermal Exhaust:


JDM H22, AEM CAI, Imagine Engineering header, Head milled .020", STR 70mm TB, STR cam gears, Crower Stage 2 cams and valve train, V-AFC tuned. (low peak tq due to tuning issues, you can see the dip)


JDM H22, Type-S pistons, 3" short ram intake, Imagine Engineering header, Head milled .020", STR 70mm TB, STR cam gears, Crower Stage 2 cams and valve train, V-AFC tuned.

 

Im thinking about getting some Crower S2's or the Skunk2 S2's. Im getting the jackson racing supercharger in the future, what ones should i get?

 

Did you dyno tune your car? What cam gear settings are you at with the Jun cams?

if your going FI then you must run FI cams. im not sure if turbo cams are the same as sc, but check into it

 

Im running the crower 2s with the big idle lobes, so far they have been good except for destroying the auto tensioner......other than that, Im happy with the low end.....I dont have numbers yet, i have to fix that little tensioner right quick before the dyno.

 

How do the larger idle lobes effect the idle...is it really ruff/noisy?

And do they cuase the car to have better low-end & Mid-range...as well as top end obviously?

Did your gas milage get better worse or stay about the same (assuming you are not in VTEC all the time now).

Thanks

Stock primary lobes are for girls

 

anyone have type S specs?

I got this info from my own measurements and Automotive Engineering,
March 1997:

Measured at 1mm lift.

Normal H22A vs. "Type-S" H22A
Intake opening (BTDC)
15°..................15°
Intake closing (ABDC)
40°..................45°
Duration: 235°..240°

Exhaust opening (BBDC)
40°..................45°
Exhaust closing (ATDC)
15°..................15°
Duration: 235°..240°

Gross valve lift measured w/1.55 rocker ratio
Normal H22A vs. "Type-S" H22A
Intake:
(mm) SAE (mm) SAE
(11.5) 0.453"..........(12.2) 0.480"

Exhaust:
(mm) SAE (mm) SAE
(10.5) 0.413"..........(11.2) 0.441"

thank you did not see them due to all of these bullshit threads that push this one 5-6 pages back. All of the official ones should be sticky

 

I just degreed stock 1993 H23A1 cams:

Measured at 0.050" lift.

Intake opening (BTDC)
-21° (so that is 21° ATDC)
Intake closing (ABDC)
24°
Duration: 183°

Exhaust opening (BBDC)
30°
Exhaust closing (ATDC)
-20° (20° BTDC)
Duration: 190°

Gross valve lift measured w/1.67 rocker ratio
Intake @ cold .003" clearance:
~0.370"

Exhaust @ cold .006 clearance:
~0.370"

You will notice that there is **** for overlap, in fact none. So this is why H23 cams suck after 5300 rpm in NA applications. The poor engine just can't breathe. It is a good cam for low end torque and boosted apps (duh).

does somebody here have crower stage 2 all motor cams on there lude with stock springs and retainers?what happens i if u leave the stock ones with crower stage 2 cams???
