Blue it's definately the vf39 we just don't seem to have the specs for it. I am going to try to contact ihi and see if they can give them to me.STIBLuE said:I looked and read everything about the STI specs nothing about what Turbo there going to use. I would just like to know the Size??
The turbo 'size' (if you wanted to simplify it as a single magnitude) can't be determined by the number. The VF34 is not the biggest IHI found on a WRX. The VF22 is. The rule is, the higher the number, the newer the turbo. That's how it typically goes (there are exceptions irrc). So, the number/name doesn't tell you anything we don't already know.STIBLuE said:The VF39 is the biggest turbocharger Subaru makes then? What size turbo does the EVO have? VF39 that sounds huge. I think the biggest I read was a VF34.
