thing I love about Hyundai's are that parts are interchangeable, so im not worried about finding parts for the job kinda just worried about the ecu business see I have other plans for the engine too.
when getting into car modification I learned that a turbocharger dose not increase economy at all... soon after VVT was introduced to me.
I believe with VVT and a higher air flow power to weight ratio goes flying but without burning double the gas. get higher power with better miles I think its depending on the engines exhaust power, and the turbo itself.
small engines cant spool up turbos at around 1-2.5k rpm wich means its like running without a turbo, no jackrabit start. VVT helps controll the amount of airflow needed meaning there should not be any air flow restrictions played by it. better airfilter are shown to increase the mpg and Horse Power, so as long as the turbo spools a little to make Intake manifold Vacume to be at 0 we would be good.
now you might be thinking that without a turbo only with a Wide open throttle can we reach 0 with is right but its not like gunning the engine.
throttle position is still lower but you are getting better air flow without the extra need for more fuel once it goes over the 0 then you are boosting and using more fuel.
tho engines do create more horse power when they are leaner they still explode when they are lean too.
and with VIT I think it would be even better.
if you remember what a turbos function is for, it was made to use the waisted power coming out of the exhaust to spin a fan that increases intake air flow.
this exhaust power is in ever gas powered vehicle and I think it should be used and not waisted because it is being created.
if I get a factory made ecu for the VVT engine it wont understand the turbo airflow.
