On the positive side: the header runners are long and wide, promising even exhaust gas distribution and good flow - both things you want in a header, and both features that are sorely lacking in the stock "log" style exhaust manifold, which is uneven and restrictive.
In evaluating this piece before installation, I can honestly say that there were things I liked about its design and things that I wished had been done differently.
This is not an inexpensive modification, something worth keeping in mind as you read through the following praise and criticism. The external wastegate, which is required, is not included in the price of the header. The turbo header comes flanged for an external wastegate and includes a 2.5" mandrel bent and TIG welded downpipe. The entire header is ceramic coated, a process which increases the life of the header by enabling it to withstand temperatures to 1,500 degrees. The TIG-welded turbo header features mandrel bent, 14 gauge, stainless steel tube runners and laser cut flanges. It comes flanged for Garrett T3-series turbochargers, which are capable of delivering significantly more performance and response than the stock CT20 turbos that Toyota shipped with the 22R-TE engine. The LC Turbo Header, Part # 26-150, is designed for the Toyota 2WD and 4WD trucks, 4Runners and Celicas powered by the 20R/22R/22RE/22RT-E engines. The engine had previously been converted to run a Garrett T3 turbocharger in place of the factory CT20, so this would truly be a test of the efficacy of the turbo header vs. My test vehicle was a 1986 4x4 truck with a factory 22RT-E (turbocharged) engine. Since I have long wanted to add a turbo header to my 22RT-E, I decided to purchase and install their turbo header. They recently introduced a turbo header and turbo kit to their product line. LC Engineering has been making performance products for Toyota 22R-series engines for over 15 years. The LC Engineering 22RE-T turbo header has some great benefits, but could use some refinement.
