Anyone know this : The exhaust housing from RB20 can be changed to match the RB25 unit? If so, theoritically, the RB20 exhaust + RB25 inlet housing match would spool faster? Thank you
A few feeks back, i went to Auto Vision to change my ATF and to do a flush. I also changed the filter and was "supposed" to change the gasket. Instead of the gasket, they used a sealant. They said no...
