I had a giggle when I saw that , knew it wouldnt work .
Fuel lines / rail too small
Throttle body too small
You would have to run stand alone , the biggest high impedance injector is 870cc @ 4 bar or about 1000cc @ 5 bar which still doesnt flow enough for the gt42 .
Biggest you can go is around a gt 3076 . That should still net you around 400whp + !
Then you would need to find an o2m box cause you'll be tearing the 02J apart !

either way unless you got a $20k+ budget your not gonna be able to get the power , and once you do unless its drag only you wont be able to use it !
