Well I finally got my k20a3 dynoed over the weekend and here are the results.
This is a before after comparison from the stock k20a3 cams vs. k20a2 cams.
I went with the k20a3 exhaust rocker set-up, i think i'm herd about it being used other places, i think* this might be one of the first times results have been posted from a a3. The rest of the engine is stock internally.
Here are some pictures of the rocker set-up...
I've actually been running this set up for a little over a month now (~1100miles) and have had no problems at all.
ok i run the k20a2 intake and exhaust cam with the k20a2 rocker arms modified to run vtec properly what is the difference betwwen my set up and yours is there any advantage of running it your way without the low cam
damn, after all the work i did to do an a1 headswap on my a3 block with skunk2 stage II cams and I only hit 180 with a PRC intake manifold, 3in intake, dcrh, and small 2.25in exhaust. I should have just done something like this with the a1 head. Maybe I will try porting my a3 head and trying this. So explain this, did you do any swapping order of the exhaust side rockers? Or is it just plain a2 cams on the exhaust side.
u make less hp and tq below 4700rpm with this setup than your stock k20a3 that is why i use the k20a2 rocker arms modified for vtec so you run on the low cams till 4700 and then switch to the high cam to get a better powerband how ur idle do u have a vid
I can't find what the spec is for the TB base setting. I'm used to Volvo's where 1/4 turn off the stop is the norm, so that's how I set this one..
The problem is I have an idle of about 1800rpm after the initial startup high-idle.
There is an additional problem where the AFR's are super rich...
The point of this thread is to compare dyno tuned charts to compare low, mid and top end gains to benefit helping us all understand where power was made and using what mods.
if you would like to share tuned calibrations to benefit others understand what different settings affect different...
There seems to be two different VTC units.
I looked up the TSX ones, and all of the years use the 15830-RBB-003 part number. The samething with 05-06 Base and Type S RSX.
While the 02-04 Base and Type S RSX use the 15830-PNC-003 part number?
Does anyone know the differences? Or are we just...

K24a4 with k20a2 head . 12.5.1 compression drag cartel 3.2. Super tech valve kit going into an integra. Have a 5 speed out of a base rsx lying around, any good reasons to go with a 6 speed over the 5? High way driving is not a problem since car never sees the highway. Also if I go 5 speed now...
