I am wanting to SC my Z and i know all about the vortech kit but i haven't heard anything about this HKS kit any input would be great. thanks

 

My input is go with an ATI procharger, the rotorex kit is very expensive for its output. The ATI is upgradeable (you can change cogs to go above 7psi) definetly can get to the 400+ mark with ATI. do a search in the forums for ATI or procharger there should be a bunch of diffrent threads about them...

 

Please search!!

free bump, someone will help you out with the info you're looking for dude. I've searched for info on the hks rotrex as well and there's just not that much out there

 

The HKS is a non-upgradable kit. While the quality is great, it is not worth the money IMO. Go with an ATI or a Vortech both of which have their own pros and cons and are both capable of over 400whp with pulley swaps.

 

IIRC they're not even selling the Rotrex anymore.........

 

To sum it up-it's weak sauce and overpriced, sorry man look elsewhere for power...
