the above is a 96 brighton full swap. this brighton came with obd2. r180, brembos and the dash. the dash doesnt fit too well because it has the old style door cards from the 93-95/6 L. rs door cards fit with the new dash but they are hard to find and cost over 350 each side. that car with stock sti swap is verry fast and i mean verry fast. i dont know why you want 540 horsepower, with a car that weighs nothing 300 is just fine
