The car is about 1300kg/2850lbs (curb weight) and has 260hp from an inline 5 cyl 2.0 litre turbo Engine and FWD.

Take a look at the Tesla based projects using the 'small' front drive unit (here) and 'small' rear drive unit (here). These typically weigh ~90kg including the transmission and inverter (so you can dump the ICE clutch, transmission, diff, etc). Peak input power is ~220 kW (294 HP).

An open source inverter controller (here) is currently being tested in several cars with a range of different Tesla 'large' and 'small' motors;

Tesla Powered BMW E31 8 Series - 'large' rear motor with Tesla battery modules

Tesla Powered Nissan 350Z - 'large' rear motor with Tesla battery modules

1967 VW Split Screen Van - "ICE Breaker" - 'small' rear motor with Tesla battery modules

1978 VW Beetle 1303 Convertible - "ICE Breaker 2" - 'small' rear motor with Leaf battery modules

The open source controller supports a wide range of battery types ranging from ~250V to ~400V. Depending on your range and top end requirements a battery containing 10 Tesla Modules might be a suitable choice.

Open source solutions are also in development for the Tesla charger (here), BMS (here), DCDC, Air Compressor, etc., etc.

If you add your location to your profile it might be possible for you to visit one of the developers and discuss your project if that's helpful.

I guess the only downside is that batteries will be expensive at 250V+ but that might be the price you have to pay for simplicity.

If you're looking for performance you'll need to invest in some decent batteries... Leaf modules are pretty cheap but probably don't have the performance you need... Volt modules might be a better fit... What's your budget?

Is there any other good reputable source selling Tesla parts?

Here is a good place to start

Thank's for bringing up CE-approval, I'll have to check with the Swedish equivalent of TÜV, that might actually be a problem here as well.

If you do need a CE certificated drivetrain then afaik New Electric are the only company that have invested in the testing of Siemens and HPEVS in Europe.

Going forward a number of people have expressed an interest in testing and certifying the Tesla components for use in countries that require it.

I built a Super Seven replica about ten years ago and then there were no rules (in Sweden) that stated parts had to be CE-approved. An electric converison follows the same approval process as my Super Seven, so I hope that this will not be an issue. I will be shure to double check this before getting to deep into the build though.

New rules were introduced across Europe in the last couple of years... some countries decided to implement more stringent requirements including EMC certification (The Netherlands). Here's a thread that discusses some of the issues;

I would suggest trying to find someone in Sweden who has registered an electric conversion recently
