    • Somebody swapped an Audi RS4 4.2 FSI V8 into a VW Transporter van and added a pair of turbos - 745+ horsepower

      There are some crazy swaps out there but BoostAddict had yet to see a Volkswagen Transporter van with over 700 horsepower. The van belongs to T4 Transformations in the UK which does various Transporter van conversions.


      They decided to get a bit nuts with this one and swapped in an Audi B7 RS4 4.2 FSI V8. They then had Fouire Fabrications add a pair of turbos:

      T4 Transformations RS4 Engined T5 got a couple of turbos fitted by Fourie Fabrications and did 745ps 817nm on the MRC Stage3 Remap. This is a stock engine, stock compression and running 10psi to start with
      On the stock motor and the stock 12.5:1 compression ratio with 10 psi of boost they are making over 700 horsepower:


      The van is pretty quick too running 12.2 @ 116 in the 1/4 mile. It is going to surprise a lot of people that is for sure.

      Why build something like this? If you have to ask you simply won't understand.

        Such a cool project, but such a poor choice of turbochargers. Thing is going to be lag city, better turbo sizing would have made this thing even more ridiculous! Honestly doesn't matter really, thing is badass

        I might be wrong but I think they plan to turn it up. Probably will require a built motor at that point.

        What turbos should they have used?

        Well if you look closely, they are older model cast wheel either GT3071, or GT3076. The 30 series units can be pretty laggy, and the cast wheels are just past their time. A couple of Gen 2 GTX2863's support 800hp, and Gen 2 GTX2867's support 900hp. They would spool a good 500+RPM faster than those old GT30's. If they wanted more head room a set of GTX2971's would support 1100WHP. Thats the size turbo we use on all our ecoboost upgrades, on a 2.3L, we have near stock spool, and 550WHP support.

        I wonder why they used old turbos, huh. Oh well, awesome project.
