Thread: Mk4 1.8t turbo mod

  1. #1

    Default Mk4 1.8t turbo mod

    Has anyone made a hybrid turbo with a ko3 and k04 turbo? And does anyone know if a 1.9 tdi turbo would fit a 1.8t?

    Yeah, Frankenturbo.

    Anything can be possible if you have the right tools and fabrication skills to install the Garrett's VNT-15 on a gas engine.

    I have the tools and skills but I've been in the performance diesel world and not trying my hand out at boosted gas engines I just wasn't sure if it would be worth it. I did crunch some numbers and was thinking the tdi turbine with ko3 compressor housing should be a quick spool and can do somewhere around 30psi but I thought I'd ask if anyone has done it or heard of it being done before.

    That is a really interesting idea. I found a few links, it seems they hybrid 15/17 together while k03/k04 hybrid together. Not sure if they hybrid k03/15 though.

    This link talks about the Garrett 15 hybrid in the Turbo section.

    I guess it's time to build myself a franken-monster lol. I will post my progress and details how to build one and the outcome of the creation, but if anyone wants to chime in and add their thoughts please do I like constructive criticism and opinions.
