What's better k20a2 or k20z3?

the k20a2 is the one you want. both are ivtec, but the k20a2 head is more like the b series vtec. the k20z3 ivtec is built for more fuel economy.

Similarly, you may ask, how can you tell the difference between k20a2 and k20a3?

The k20a2 has higher compression pistons, more agressive cams, dual valve springs, and a tri-Y header with larger primaries than the k20a3. If that wasn't enough, the K20a2 has a completely different - and more advanced - method of iVTEC than the a3.

Also, how much boost can a stock k20z3 handle? But stock internals should hold 14-16lbs of boost.

In this regard, is the k20z3 a good engine?

Once again, not doubt the K20Z3 is superior to the B series and it's one of the best NA 4 cyl engines made. I now agree with the other two posters who said the Civic couldn't make more HP then Honda's flagship sportscar.

How much HP does a k20z3 have?

The 2.0-liter, dual-overhead camshaft K20Z3 engine in the Civic Si Sedan produces 197 horsepower at 7800 rpm and 139 lb. -ft. of torque at 6100 rpm.

Is k20 better than k24?

For most street applications, the K20 provides more than enough power to push a lightweight Honda around. For those who want more low-end torque and more over-all power, the K24 is the better choice if you're willing to pay for it.

Which k24 is best for boost?

The best combination for good power and good torque would be the k20/k24 head and block combination. k24a2 (tsx-short block), and k24a1 (accord long-block). I think the k24a1 accord block is taller and hence has better piston/valve clearance if you plan on running the vtc beyond 40 degrees.

Which is the best k24 engine?

The tsx will be the best k24 block but will also be the most expensive by a lot. k24a2, tsx motor~ $2500-3k. K24a3 and K24a4, accord and element block, need to change pistons, usually a lot cheaper, $500-$900.

What RPM does VTEC kick?

At 3000-5400 RPM, depending on load, one of the VTEC solenoids engages, which causes the second valve to lock onto the first valve's camshaft lobe. Also called 16-valve mode, this method resembles a normal engine operating mode and improves the mid-range power curve.

How much boost can a stock k20a2 handle?

Registered. Theres some out there boosting 20 psi. If you go with a gt3076r, you will have good spool time(3500 rpm full boost) and make your goals. If 300 or 400 is your goal, you should have no problem with the stock motor.
