You might remember Furches Performance’s FWD Monte Carlo with a turbocharged LS4 V8 we shared last month. Since then Brandon Furches received many questions about how he mated the LS4 V8 to a 4T80E automatic transaxle. So much so that he made a video explaining how he did it. Listen as Brandon explains how to combine a 4T80E with a LS4 and make sure to read the description (on YouTube) which includes valuable tips not covered in the video.

I’m prepping to do this swap on my cammed 06 GXP. I have HP Tuners and an curious what is needed for the swap (tuning wise)? I may be asking something dumb but I’m just starting this project. If it’s tuneable with my current ecm a copy of your trans tune to get me started would be great if you don’t mind? Thank you for your time.
Hi Matthew. I recommend contacting the builder at Furches Performance.
could this go in a 60s/70s vw beetle? would the motor be in front or behind the axles
Please advise me how to use a 500 cu” Caddy on a 4T80e. Thanks, Richard waughrichard@yahoo.com
Never happen the 4T80E is V6/90 bolt pattern it won’t adapt to BOPC bolt pattern
