did anyone got that email from honda? i don't know if it has been posted, SI has been confirmed with a k-series, K20Z3.

• Compression Ratio 10.5:1
• Improved fuel efficiency
• Significantly advanced low rpm torque and top-end power

Civic Si

139 torque is shitty!

yes, a 2.0-liter, DOHC iVTEC® 4-cylinder engine K20Z3

so the next question, whats the diff between the a3 and the z3? besides the numbers

 
Rep Power: 424

The Z3 is true DOHC VTEC like the K20Z1. The A3 was variable intake lift only. My guess is the Z3 is a K20A2 with some minor change to the cam profile that warranted number changing.

that's pretty cool... wonder if there's a k20z or k20z2 out there somewhere

hmmm, in that case i would if u'd need to change the cams or the entire head to reach z1 numbers

Significantly advanced low rpm torque and top-end power

lol! nice try

i jus got my car and driver a few days ago; and they already reviewed the Si with great ratings

Get out of the dark. Temple of VTEC has everything you want to know abou the Si, including some good powertrain info with regards to the naming scheme and such.

Its more like a euro R engine.

The balancer shaft of the si is heavier than the The Type S engine resulting in a few less HP on the Dyno (Inertia). Its advatange is however it revs up smoother than the K20Z1. The transmission gears 1 through 5 are the same as the type S, gear 6 is taller and the final drive is the same of the 2005 Type S.

So its an improvement over the k20a2 or k20z1.

ok simple question. if you're driving a stick and let's say you're on gear 5. do you have to put it in gear 4, then 3, then 2, then 1, before going to a full stop and brake? or can you just put the gear on neutral whatever gear you're in then clutch brake right away?

 
Rep Power: 313

You can just go to neutral then hit the brakes. I personally go down the gears and use the engine to stop the car, then I apply my brakes.

thanks man. i always thought about that because everytime i drive a stick (uncles truck) i just put it in neutral then break when i'm about to stop on the light. never did i do the slowing down the gears.

never downshift into first, just dont

 
Rep Power: 0

what do you mean? u mean the last downshift is at 2nd gear? does that also mean, never fully stop on gear 1? instead you put in neutral, fully stop, then gear 1 when about to go?

 
Rep Power: 321

1st gear only meant for starting out, never downshift to first gear. As far as breaking i know I shift into neutral when coming to a stop, never ride the clutch. I guess downshifting fromt 5th,4th,3rd,2nd will work too.
