Starlet 2e Ep81 Manual

Hello,
I'm new here, and have a lot of questions regarding the Starlet EP82 GT Turbo which I hope you can answer.
My quest is to build a left-hand drive Starlet GT Turbo as I live in Denmark. Denmark have very strict rules in tuning and lot of documentation is needed to get the mods authorized. I'm aiming to get all mods authorized as I don't wanna mess with the ensuarance companys.
In order for them to accept the conversion from a Starlet EP81 1,3 XLi with 75bhp to a Starlet EP82 1,3 GT Turbo you have to document :
- Technical suitablity - You have to document that the increase in bhp and topspeed can be handled by the supension and brakes. This has been documented before in a BMW 320->325 conversion where they documented that the 320 and 325 uses the exact same suspension, and that the brakes had been upgraded to the same size discs as the 325 uses. So I need to document that EP81 and EP82 bodys is the same and I used the brakes and suspension from an EP82.
- Emission requirements - The new motor must meet the same standard as the original motor, and this need documentation. This documentation can be done by either sending the car to Germany for emissiontesting (costs 1500£ per test, so this is not an option) OR find car which uses the same motor and some papers on what emissions standard it follows.
1. question. The only difference in Toyota Starlet EP80, EP81 and EP82 is motorsize (EP80 = 1.0l , EP81 = 1,3l, EP82 = 1,3l Turbo...) and luxuary equipment such as air condition, power steering etc. The body of the cars is the exact same?
2. question. Does parts for EP82 bolt directly on EP80/EP81 without any mods? then it will be easy to document that I swapped the entire suspension with the one from an EP82.
3. question. The Starlets in Denmark have to approve the Euro1 standard in emission. Since Great Brittain is also an EU country I think you have to follow the same standards, but it seems you have some special MOT tests for exhaust emission that the car has to pass quiet often? Anyone how have a link to the british standard emission standard or documentation that it follows euro1?
The euro1 standard says 2,72g CO per km I think.
