Description

The HTHRacing TRB-KIT-K20-CIVIC0611-GT35 is a comprehensive turbocharger system designed for K20 engines, specifically for the 2005-2011 Honda Civic Si FA/FG/FK/FN/FD chassis. This kit includes a GT35 turbocharger, a thick-wall turbo manifold, and a downpipe. It is engineered to support up to 500 horsepower, making it suitable for enthusiasts seeking significant performance gains. The turbocharger specifications include a 3-inch inlet diameter and a 2-inch outlet diameter, with a 1/8 NPT oil inlet. The compressor features a .55 trim and a .50 A/R, while the turbine has a .50 A/R. The kit is designed for converting naturally aspirated K20 engines to a turbocharged setup.
