so I am seriously considering this kit
http://www.gmpartshouse.com/19212670-lnf-turbo-upgrade-kit.php

It seems that the harder I drive the car and spin up the turbo's the faster the car drives which would lead me to assume that this turbo upgrade kit would increase the performance of the Karma..

I have a few questions, I know there are some tech's here, or at least used to be :)

Does the ECU for the ICE needs to be flashed?
and is the ECU custom for the fisker?

so this is all fine..
TMAP sensors
Connector pigtail
just some minor rewiring. :)

This upgrade was available as a factory-installed GM option on the Ecotec LNF motors but Fisker decided to get the standard ones, so that should tell you something about whether it would get you any advantage.

Also, you may consider this post by Nimsys that seems to indicate that the ICE never exceeds 235 HP and that the maximum theoretical capacity of the generator is 250 HP, which means that the extra 30 HP from the upgrade would never actually be used, even if it were available. Unless you are confident you can hack into Fisker's bespoke Hybrid Control Software to change the car's operational limits, all you are doing is adding weight and complexity to your car. And even if you can modify the software, you are risking pushing the generator and the generator's inverter beyond their rated limits which I am guessing the Inverter will not allow you to do, at least for very long.

Finally, I am not even going to consider what effect modifying the ICE will have on your warranty.

Not trying to rain on your parade here, but I would suggest thinking this through carefully before modifying the ICE in your Karma.

The ICE isn't the limiting factor in the Karma's performance. So I don't see the point in upgrading ICE components.

Actually, recall in Fisker's response letter to the Texas fire they said that the ICE never operates at a peak power output of more than 170hp or 180hp @ 3500rpms, well below its 260hp limit. This was all new to most of us, as we thought it was working hard given the harsh sound when the accelerator was mashed.

Right. There's still plenty of overhead in the existing ICE, so no reason to go swapping the turbo, etc.

I suppose one could probably do the equivalent of "flashing the ECU" to get more performance. I believe Fisker has things set as they are now to mitigate NVH issues.

Upgrading the ICE is like pimp your IPhone charger and hoping to shoot the Angry Birds faster. I believe you would need to increase the current limit from the battery to the e-engines.

This discussion makes me feel better knowing that the Karma's performance can be enhanced with some software tweaks and without having to replace any of the hardware. Seems that Fisker were very conservative with both the electrical and ICE-related components' operational limits, and thus left a lot of KWH/HP on the table that we can potentially utilise once they get more confident with the drivetrain and modify the software to allow us to get closer to the limits, or even to exceed them briefly down the road.

Dropping weight is probably the only hack worth pursuing on this one. Maybe in the future there will be some cool "chips" out there to turn your Karma into a monster. But for now, if you would be willing to chuck the solar roof for a lighter look-a-like and maybe finding some lighter seat options, you would be more happy than with the engine upgrade.
