I have a set of brand new SZ expansion dps in 3 inch SS 5 bolt that are coated ceramic and polished. $685 . These are from before they switched to the new cheaper supplier.
Used HKS2530 bb turbos, spin freely, no issues when removed from customers car. Turbine housings are ceramic coated but a but the ceramic is no longer shiney. As with all hks turbo's they have provision for egt probes in the turbine housing. Asking $2400
