The 2009 K20 was an i-VTEC "High Performance" engine tuned for power. The new one is a different engine tuned for maximum economy, and no i-VTEC. IRL, the 1.5T in regular, non-Si tune, approaches that 197hp, with more torque than the old 2.0Si engine, in the case of the 6MT Sport / Sport Touring Hatch. (Close to 200hp/200lb.ft torque). A regular 10G Civic Turbo is faster than a 9G Si (Stock vs Stock).
The new 2.0 is an I-Vtec. And with the ktuner you can lower the Vtec engagement. My old 2008 Honda Fit has the fuel efficient Vtec version 1.5 engine. It would only open one intake valve during normal operation to save fuel. Then it would open the second valve during Vtec engagement. So it didn’t have lift control. Lift control is where it makes more power on the top end, which is found in the new 2.0. It’s just missing lift control on the exhaust side like the old 2.0 had, which is how it had such a high useable rpm range.

Yeah anybody who rides with me are surprised with the power it’s got. It might be the base engine but it’s no slouch.

My 2010 Si would scream. Fun car miss that car. Nothing beats Reving it out to 8500 rpms. Except mid range torque. God I love my 19 Si

The 09 civic SI has a K20Z1 I believe and that has true VTEC ringing out the rpms to near if not 9000 RPM. And the 2016+ (FC2 sedan an coupes) have a K20C1 as there base model engine, making 158 HP and 128TQ from factory on the crank, or so they say. But the difference is as where your k20Z1 has a true VTEC platform, the FC2's K20C1 is with a what they call I-VTEC, but is actually a EI-VTEC( Efficiency Intelligent Variable Timing and Electronic lift Control).

What EI-VTEC does is kind the best of both world where its cammed for fuel efficiency then power. Plus it revs to only 6700 rpm and "VTEC" does not always kick in bro.
Correction 2006-2011 Civic SI used the K20Z3.
The K20Z1 was used on the 2005-2006 Acura Type S.

The Vtec on the new 2.0 is set from the factory to 6400 rpm which is really high. But with a ktuner it gets lowered to 5600 rpm which makes a big difference.
