    Wink Turbo upgrades

    Has anybody heard of turbo upgrades for the optima 2.0t? Thought I'd start a thread because I'd love to get a bigger turbo.

    As far as I know, the stock turbo is integrated into the exhaust manifold (like the GTR). So someone would potentially have to make a whole package that included an exhaust manifold and downpipe at minimum. I don't know if this has been done already with the Optima since I haven't been around very long. But I'd seriously doubt it since it's considered a sporty family sedan. But you never know!

    You could look at getting the larger turbo/exhaust manifold from the current gen EVO - same engine, different compression and turbo. Then you would need to write new software code, and steal the heads off off the donor EVO engine to lower your compression so you can increase the boost.

    That there engine is just about maxed out. A new turbo is prohibitively complicated....we'd get some decent gains out of a software reflash, I personally would concentrate my efforts on bugging tuner companies.

    Yeah I've been bugging the **** out of everybody. I'd like to produce around 350whp, a bigger turbo would completely change are cars. Somebody will eventually produce a bigger bolt on turbo. I've already talked to turbonetics about this and they are looking into it but are not sure when it will be available.

    It wont be that hard to do as long as we can find a way around the electronic wastegate actuator. Thats gonna be the fun part.

    ^^ That's right - the engine's performance and fuel efficiency characteristics are so closely linked to the turbo's location, it's being a twiin impeller design, and the fact that the software can manage the wastegate so precisely (cuz it's not mechanical/pressure controlled) - that's how we get the almost zero-lag, and 34 mg fuel economy with 274 HP. I also read an article somewhere about the engine internals, and the Hyundai engineers were quoted as saying the HP possibilities are almost maxed out, that it could maybe/only safely get into the high 280's without danger of destruction.

    I would assume the tuner would handle that. Who that tuner is I do not know. But my S4 has less lag with these turbos than the smaller ones did. I don't know what the tuner did, but I love ECU controlled boost! :-)

    need a ecu tuner before you bother looking at swaping turbos and stuff. Can't so anything with out a proper tune.

    Even slapping on intakes/turbo-back exhausts change the A/F ratio and should be tuned for imo.

    Sounds like you should have bought an EVO.
    Good luck with this mod...you don't know what kind of monster you'd be unleashing, and I'm not talking WOW, more like, will it ever work.
    Youll never get that kind of power to be usable in this kind of car, without a completely new drivetrain and computer programming.

    This thread should have been titled, BEAUTIFUL DREAMER!, IMO.
