    I've asked some tips about this engine at one Japanese guy and that's what i've found, IT'S ASTONISHING!!!!https://minkara.carview.co.jp/smart/userid/283168/car/736457/2104007/note.aspx?fbclid=IwAR0UEZAcFEBgBz6JpiNo_Mmgg998c3L1pp0P6g5eUD-VKKYm9U9cZuK5DWE and a throttle body mod...

    I feel the same way..i think the ecu is the very limit of the engine.. My very next mod is a straight muffler to improve gas exhaustion, which helps gains power to the high rpm range.. By the way the 3rd gear spool up over 110 kmh.. (65mph?) Did you follow Rauf cars on youtube? He has an 120bhp...

    Here we are with an update! I tryied the car with the air conveyor mod and it’s really improved, it’s super-ready at the throttle, a more rapid response, and more you push more you have because the in-pressure raise... big thumbs up at this mod, super recommended. And A sprintfilter sport...

    I’ve done a new mod in these days, an upgraded air feed for my little nissan note: that’s the before without the grill removed that’s the before with the grill removed, how you can see the air can pass through only by these little holes.. After porting the plastics ( you can see the scoop upon...

    The downside of which mod? The seats removal or intake mod? And in both cases why downside? I'm sorry but i'm a english newbie and i don't understand some common saying..? By the way with these mods the car it's completely transformed..it take corners in maravellous way without squeaking the...

    Yeah it is, i’ve fitted the new intake hose, The gas pedal seems more responsive, more ready, it’s clearly a gain in term of the immediate availability need of air from the engine... By the way, i’ve removed the rear seats, ( 50 kg) The car Have a more responsitive steering and it Feels...

    Improving the breathing on the K12 CR range of engines (Now Fitted)

    I'm not obligated to do this fortunately, i mean take attention to the bonnet because it's not fitted into the slam panel but in a lower and smaller subframe..then for that i'm completely in safe.. On the other side i don't have a big flat surface where i can easily fit the scoop, instead i am...

    Why i have to cut in this shape? For the flux direction? I think the flux anyway reach the elbow in the same way.. or not? I think the feed’s edge re-direct flows Indipendently and it doesn’t matters the beginning of the rim/feed/scoop. So you’re agreeing me? Tell me your idea..

    Now we have all we need! Let's begin now! (don't look so much at the garage, it's not mine, i'm not so messy..) Beginning with a cleanse from the excess of glue around the feed and his friend spigot Creating some space with a grinder, some file shaping, using some chisel to blow off the teeth...

    I do not buy other parts because i've already spent 40€ and that's enough, plus 60 for sprintfilter, i will file it creating necessary space to fit it without problems.. I've found some thin reflective materials, maybe one day i'll fit under it..

    Hi John, yeah i’m pretty sure it’s that the reason for the hole.. but it’s worse for performance soaking warm air.... I was thinking to insulate the upper airbox from the rocker cover.. what do you mind? And what about lower airbox resonator? It is better pluging it? It’s definitely better the...
