I have a ‘97 c5 a4 with an LS1 and I’m planning on swapping in a remanufactured LQ4, will the lq4 just drop right in and connect to the stock pcm and electronics if I have ls1/ls6 accessories on it or are there sensors that won’t work or wiring harnesses I’ll need etc
Thanks in advance

You will need to drill one hole in the front of the block for the alternator bracket. Otherwise all will bolt on like it was meant to be.
Well,you WILL have another 100# on the front end....

Thank you kind sir, I’m not super super worried abt the 100 on the front end because I find the comfortability a 0 mile iron block gives me to be worth it with boost. I just got a great deal on the car runs great with a 220k mile ls1 but I do plan on poppin that old old motor out and rebuilding the transmission so I pretty much have a newer, faster vette for pennies on the dollar
