those injectors might be good to about 300whp at the most, after that youll be running near 100% duty cycle. also i wouldnt boost more that 10psi on that bottom end. 10psi on that turbo should be quite a bit cfm and should produce some pretty decent numbers, thats if that stock 1.8 revving to only 7k can spool it up. also, you might run into the problem of the car falling on its face in between gears
