8th Gen Vtec head on 7th Gen
Hi,
i duuno if this was the right place to post so if its in the wrong place move it plz.
anywho i was wondering if its possible to put the 8th Gen I-Vtec on a 7th Gen.
im in australia and we gont get the 7th gen vtecs here, and i want to see if it possible cos i would like the small amount grunt the vtecs have.
thanx in advanced

Our motors are just too different the new technology of I-Vtec is nothing like the traditional VTEC plus the 8th gen civic has drive by wire anyway.
Civic: i-VTEC Valve Control System
To achieve more performance and more fuel economy, the Civic's 1.8-liter i-VTEC engine uses an innovative and new valve control timing to minimize pumping losses during cruising and low engine load situations, an important factor in creating more efficient engines. Pumping losses are lowered when the variable valve timing allows an intake valve to remain open for a brief time period as the piston begins its compression stroke. By keeping an intake valve open during part of the compression stroke, some of the volume of unburned air/fuel mixture in the cylinder moves back inside the intake manifold and lowers the volume being compressed, or \"pumped.\"
The pumping loss reduction yields enhanced fuel economy similar to an engine with a smaller displacement (the equivalent of a 1.5-liter engine) during cruising.
During cruising or other stable, low-load driving conditions, the new engine utilizes a dedicated set of cams to close one of the intake valves and retard that valve's timing, exerting backpressure on the air-fuel mixture.
This reduces the actual intake air volume. Meanwhile, the throttle is opened wider to provide optimum control over engine output. Opening the throttle valve, in other words, widening the path that the air flows through – reduces pumping losses to result in a significant improvement in engine efficiency.
During high load situations, the VTEC system provides high output valve timing for maximum power. Gone is the normal valve timing, replaced by two fundamentally greater extremes. A dual-stage air intake, a lightweight powertrain and optimized gearing further add to the performance character of the vehicle.
Whereas traditional VTEC operation changes valve opening duration based on higher oil pressure during high rpm operation at one side of the valvetrain's rocker arms, the Civic's i-VTEC system can switch valve timing duration at low rpm and low oil pressure using two hydraulic actuators on both sides of the intake rocker arm. This engagement method is similar to that used on the Civic Hybrid, Accord Hybrid and Odyssey i-VTEC systems.
This Civic's i-VTEC valve timing reacts to driving conditions related to throttle opening, vehicle speed, engine rpm and gear selection. A sophisticated drive-by-wire throttle control, air flow meter and dual-stage air intake allow the Engine Control Unit (ECU) to create seamless transitions between the two modes of engine operation.
You're better off buying a VTEC head off someone in America, the price shouldn't be too high for you since the US dollar has gone down in the dumps in relation to international currency.

Rep Power: 0 You can use the head off the civic VI (hatch) same motor but with Vtec. It will be costly unless you can do all the work yourself or find it cheap at a junk yard. Got to weigh up the cost vesus the outcome.
