Does anyone have these or know much about them?

There's not much info on the JWT site but they seem quite cheap.

Well i have the Sport 500s,and after 2 previous zeds with stock turbos with de-cat mongoose system i thought that the spool up etc was very good,but these 500s are wicked in comparison,so much power so quick,when i first got my present zed with these turbos they actually caught me out on a roundabout on way home from picking it up,respect is now certainly given to them,would defo recomend them,and they bolt straight on ,no mods,and easy for 500bhp,the 600s require some modification to fit,:D Tony

Sport 600 Turbocharger

•600 HP potential.

 

•Significant air flow increase from 4200 RPM

 

•Relatively good spool-up with dual POP-Charger system installed.

 

•Bolts on without modification using all stock components.

 

 

The Sport 600 is designed for engines capable of up to 600 HP. They produce a significant air flow increase at moderate to high boost levels due to their low back-pressure design.
