found out something interesting today...

when the engine temp is below 30degree C - VTEC will not engage

lol and no, i wasnt revving the sh*t out of a cold engine, the engine temp was actually 92degree and oil temp 85degree... ECU just thought it was cold (trying to see if on cold start the engine advances ignition / increases fuel)

hehehe

ok so update is:

the K20 head puts the water outlet in a different spot, so my custom made air intake now sits directly ontop of the radiator hose, meaning my intake is about 50-60degrees

sucking in hot air = sluggish performance!

so i must make up a new intake... more time and money!

as for the stock ecu - when running with the J32A3 throttle body, the a/f ratios sit similar to what they used to, except under vtec... they used to sit around 11, they now lean out to 13.5... so im loosing power there!

im playing around with my options, i only drove it around for a day, so given more time i can see it learning... otherwise i may go piggyback ecu

thanks for the update!

The toda headers look good glowing like that - nice and even too so the flow is obviously pretty damn even across all primaries. How did you take that picture (how hot does the manifold have to be?)

I'm also curious as to why you didn't just change the cams? I'd always thought that in terms of flow the Accord euro k24a head was essentially the same as the DC5r k20a head?

You're probably getting sick of me saying this now, but...

definitely get this thing tuned! You're really not going to make the most out of the k20 head and all of your modifications unless you do. I also want to know what the real gains are when changing heads!
