Quick Answer: What’S Better K20a2 Or K20z3?

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..

Is it worth building a k20a3?

k20a3 is not worth building. you need high compression to be able to utilize power at high rpms … k20a3 compression just isn’t high enough.

How much horsepower does a k20 VTEC have?

How much HP can a k20 handle?

The K20 motor can handle about 318-326hp with no problem. But if you want more hp change out the rods and pistons.

How much boost can a 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.

Which is better k20 or k24?

If you’re on a super tight budget, the K20 is a better choice, as it’s super cheap and easy to find. The K24 is a little bit more expensive, but the extra 400cc of displacement allows for more power.

What RPM does VTEC kick?

It depends on the engine. Most Hondas had vtec crossover in the low to mid 5000rpm range. You had 2 camshaft profiles, 1 optimized for low-mid rpm driveability and fuel economy and another for mid-high rpm power.

What is the difference between k20a2 and k20a3?

“The EP Civic Si’s DOHC i-VTEC engine (K20A3) has the i-VTEC on the intake side only, plus the VTEC-E mechanism for low-RPM fuel economy – while the DC5 RSX Type-S (K20A2) has i-VTEC on both the intake and exhaust cams.

Does a k20a2 have VTEC?

The K20A2 is the “real” DOHC i-VTEC engine, utilizing the standard DOHC VTEC cam setup we’re all familiar with. To help you understand the differences between the K20A2 and K20A3 engines. Let’s start out by defining some terms: VTEC – Variable valve Timing and lift Electronic Control.

Can you put a k20a2 head on a k20a3?

Yes, the k20a2 head can swap directly onto the k20a3. You will need the k20a2 ecu as well or a reprogrammed k20a3 ecu.

Is the k20a3 a good motor?

The K20A3 has the power of a B16, more torque though. It is a decent motor compared to the B-series.

How much HP does a k20z3 have?

Is k20a3 VTEC?

The K20A3 uses only two cam lobe profiles on the inlet. Under 2200 rpm, this engine is a effectively a 12 valve engine, and over 2200 rpm it is a 16 valve. There is no VTEC mechanism on the K20A3 exhaust valves.

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.

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.
