The T62R is the largest series of turbo that HKS currently makes, larger than their former flagship model, the T51R series. Because of its enormous size, this turbo takes longer to spool than the GT turbo series and is only recommended on engines 2.6 liter and larger (also on rotary engines). HKS claims this Turbocharger is capable of reaching a maximum of 1200hp but here at Future Motorsports have pushed this turbo to 1343hp on numerous occassions without issues.
