You have to go in order here....you can't just slap a big turbo on and drive the car. 1st fix your car so that it runs right as it sits now. Then once you get that taken care you'll need supporting mods for the bigger turbo. Which will include bigger injectors, but in order to run bigger injectors (correctly) you will need a way to tune the car (s-afc or any other tuning device). Btw way, I gave you my compression gauge when you bought the car....you could have tested it before buying it.
As far as the 15.1, I also think it has nothing ot do with the car but rather with your driving. You ARE making 340whp, reguarless of being tuned or untuned and reguarless of your compression. If a stock supra with less power than you runs 14's, you should be going faster because you DO HAVE more power. That's not to say that you wouldn't have more power (and therefore still faster times at the track) if you fixed your car, but as it sits you should be running faster than a 15 with 340hp.
