so tempted to do one of this project on my dd myvi.. Currently, uphill mex highway also struggle.
Btw hex, do you mind sharing your setup(management, turbo, injector size, gasket mm) ? saw your graph, around 4-4.5k, afr dipping. is that ok ah?
Management= E-Manage blue(dyno and tuning done at GT Auto by thomas)
Turbo= stock YRV
Injector= YRV injectors
Engine= Stock internals+gaskets. All main screws changed to studs
Exhaust= 2.2inch
Suspension= BC Racing BR Series Coilover
Fuel system= Walbro racing fuel pump/Fuel regulator
Brakes= Honda odyssey single pot/Sumitomo brake pads
Tyres= 195/50/15 AD08R yokohama
Additional mods= Oil cooler/Atf cooler(Reliability)/1.3 bar works radiator cap
Engine/Gearbox oil= Motul 4100 15w50, GB = sunoco fully synthetic
Installed an additional walbro fuel pump and a fuel regulator for a better fuel pressure on high rev.
A friend of mine who had the previous setup on an automatic had constant gearbox flare but he had no ATF cooler. So i decided to install a ATF cooler and have never experience a flare.
For the injectors, what I can recommend is to use stock myvi injectors, and have an additional not mistaken 1000cc injector which will be activated during boost only(since e-manage blue cannot control injector spray) This will be very fuel economical instead of upgrading all injectors.
Previously noticed a slight temperature increase during top speed/100% foot down. Solved by changing to a 1.3 bar radiator cap.
Future plans. Aiming 200hp
1. Upgrading to a bigger turbo
2. Overhaul+Strengthen engine internals, using YRV pistons,installing oil jet
3. Changing to a manual transmission if my GF wants to be a rider haha
4. Replacing back to stock injectors, and adding an additional 1000cc injector which will be activated during boost only.
Anyways I don't plan to put too much power on the little myvi, the car itself is not design to withstand so much power, other parts would start to wear off eventually. Would prefer to spend on a more suitable sports car(saving up for a skyline R34 :D)
Mechanic= Fuelworks performance garage in batu caves(basically 10 meters away from jian hang)
Exhaust= Jian hang exhaust in batu cave
tuning= GT Auto Sunway
