Audi 80 t89 really great with power!

Hello, I’m new here! I have an Audi 80 t89 Bj 87 with the 1.8S 90PS, but the engine sucks because I need more power! I’ve been 18 for half a year and have been driving the car ever since! The car is optically really horny and looks like the car has 500hp but now I want to have a bigger engine! Had he made chip tuning, bought a chip from ebay and built in with a buddy, after that the part went off well, the chip should have the Wa I want to install a 20V Turbo now, which will then also get such an ebay chip so that it gets real power! Would you like to ask with what cost I have to calculate, engine I already have over 300tkm down, but doesn’t matter, do I come with 500€? Because that’s all I have because I’m still Azubi! Dude thinks the old brake can stay in it, that’s right? I also got 140hp and you can notice that, but I still need more power! already bought a fat new spoiler so that I have a really good press pressure on the highway later on, the old BMW should not have anything to do with me, no buck me to let them heat me up! Had a really cool race against a 3 Series BMW was really cool, really let the engines awoke and then let go with full speed, that was fat, but the guy in the BMW didn’t expect that I had such a fat tuning chip in it and therefore didn’t follow. So people tell me what I have to do! Sports exhaust I have already lying here for this, which also brings another 30hp as well as an open sports air filter I already have which should also bring again 7hp, that will become a murderer carre, will certainly have around the 300hp when everything is finished!
