As title says, what is the absolute most responsive aftermarket turbo available for an RB25?
The factory turbo on R33's delivers great response and driveability and can deliver around 10psi of boost safely without spinning the ceramic turbine wheel off.
If not for the ceramic turbine wheel, would I be correct in assuming that the factory turbo would be able to deliver roughly 14psi without losing efficiency, and make around 230rwkw?
Is there a turbo with similar A/R's, trims etc to the factory Garrett but with steel/inconel/alloy wheels?
If so name it please!
