Hi, I'm looking in to doing the 20v turbo conversion. I have a hgt 155. I've read lots of threads and been on different forums but can't seem to get close to what I want to no! I'm aware the 155 has a few differences to the 147! Electronic odometer and a vis system and 147 hasn't. Question is will the looms be different to one another? As I've heard the 147 is plug and play with the turbo lump?

The technology between the two cars is unbelievable

I'm currently doing a turbo conversion on my 155 marea
And been told to expect 2 days just wiring

The braking system is also different
