So I was thinking about a vr6 swap after I get my hands on a mk1
And I came across a website that sells a conversion kits MK1 VR6 Conversion Stage 1 + [EWMK1VR6S1] - $999.99 : Welcome to Eurowise Webstore

They also have wiring to join up to the stock wiring that should be released soon

So has anyone done the conversion kit ? Or one like this
And what are the most common problems when doing the swap ?
Thanks guys
