would be that if Z1 uses the same spec parts as JWT does then it might be worth the little savings since they both would be building the turbos from other manufacturers parts. One question I have is why Z1 is selling their 500 turbo for 1650 when I saw a post where John said that they were selling their 550-600 (inbetween a JWT 500 &600) turbo for 1600?!?!?
Z is back and running!!!! If it's not one thing it's another!!
