Evening people, hope everyone is well.
As some people will know I run a youtube channel and have well documented the CR140 and CR170 engine swap series, if you have not seen it go check them out @Jonbuildz on youtube.
However It's time to level up and complete a TFSI conversion and I will keep this thread active once achieved.

Re: TFSI Engine Conversion
So before everyone thinks I’ve gave up on here (it’s all uploaded to my YouTube but I love a forum post ) let’s start to walk through the project.

Re: TFSI Engine Conversion
So we had to strip down the TFSI making sure we took the required pieces. This only cost me £600 so it was a cheap tfsi but had a gearbox fault (dsg).
