The new TD05-68HTA is FP's successor to their former 18G turbo and utilizes Hydraulic Turbine Assisted (HTA) compressor technology, allowing the 68HTA to operate with less backpressure and lower compressor outlet temperatures to maximize low and mid-range rpm boost response. This means that the 68HTA compressor is capable of pushing a max volume of 47lb/min while still spooling faster than any standard 18G. The 68HTA TD05 (2.4 inch inlet) compressor housing is coupled with a 7cm exhaust housing, designed for the best compromise between top end power and boost response. The TD05-68HTA features an internal wastegate and includes an 8psi wastegate actuator designed to offer the best performance when tuned between 18-28psi. The TD05 68HTA is a true 350whp turbo with a noticeable but tolerable lag increase on a 2.0 WRX. The 68HTA is a good 'medium' sized turbo option for 2.5 WRX and STI models, ideal for low and mid range power with an incredibly fast spool. You can expect the FP 68HTA to make between 320-360whp when tuned with proper supporting modifications.
