Turbo! Not sure how difficult but an LS swap would be just as awesome too. The 4.2 is a special engine but the power, price and simplicity of an LS is unmatched.
Still awesome either way. Looking forward to next video! Great car and appreciate the attention to detail.
@@aaronlive1541 this depends. If you are to use only the stock pulley that comes with the kit, then yes you can have the insides all stock. But going to a smaller pulley, it is best to have at least upgraded rods. ( @amtuned sells them). As for piston. There is still no info on exactly how much the stock pistons can withstand. But in my set up I still am using the stock pistons, no issues so far
I have a feeling, you're on-brand with yellow accents. Looking forward to seeing the new prototype in your car. Congrats!
Where did you get the 7psi pulley for the VF? I believe you ran a bigger pulley, correct?
The smaller pulley I got from Alex at amtuned. And I did run the larger pulley back when the engine was completely stock inside. Switched over to the smaller pulley when I got the engine built from Alex with the stage 1engine build
Love the vids and sick S4. I’m near Denver too, driving a B7 S4 Avant manual and a big turbo UrS6. I feel like my S4 is putting down 100 hp at this altitude. Ha.
Thank you! Haha yes unfortunately altitude is a big enemy to NA cars. But I'm sure the urs4 is a blast to drive!
