I have swap my V6 for a 4.6 and i can say yes u do need donor car? Is there anyone who has done this and can give me some tips. I have a 2003 mustang with a 2004 4.6 engine and tramission. Im on my final stages and just want sum tips. I love the new power no regrets.
how far along are you? im doing one myself. little more work than i expected. waiting on Sniper tuning program for my lap top to flash the box and tune it. Made alot of improvements long tubes,pro chamber no cats, cold air, k-member ect ect. did not have donor car so its taking me a while to finish it. mitch
