s3alex how do you find your turbo conversion? is it the best option to go for?
The good news,if you like,is that the development work has all been done,and AMD can fit you something that will work,and doesn't require all manner of cutting and bending to get it in,which is how the kits from the USA arrive.
There's no questioning the quality of the BSH kit,but it IS very expensive,and still requires some work to get it sorted for an RHD car,and the major plus is the tubular manifold,which GT3Turbo can make up in any case,should you need maximum top end power.
Mine is the ATP kit,which is nicely sorted by AMD and GT3Turbo,and works well...I chose a GT3071 as the thing runs up quicker than a GT 3076,and is more usable in that respect.
Personally,I'm happy with this kit,and those who've had a run in it will vouch for the power over at VAGOC......there are still a couple of mapping issues to be sorted,but that's not a big deal,and the other thing is fuelling,as most of the kits using RS4 injectors do smoke a bit when you hoof it.
That's an injector related thing,and not something you can do much about aside from maybe reducing the fuelling,but that has it's own problems,hence the mapping.
You will need a bigger intercooler,and a good wad of cash...I reckon the thick end of £5-6k all in,excluding brakes,suspension etc.
