Looking at the January 2009 version of Option Magazine we found a section on quick and durable tuning at around the 500ps mark on a variety of engines. One of them was the 13B-REW with RE-Amemiya's mechanic Aoki-san's comments. The theme of the article is Get the Good Balance. Starting off with some maintenance tips on checking the ignition coils and making sure that you are cooling the engine correctly the article jumps right in to using 3-piece Apex Seals as the OEM 2-piece units are not recommended for over 450ps. Obivously recommending the 3-Piece RE-Amemiya seals it is also noted that these 3-piece seals are also used in the RE-Amemiya D1 GP FD3S. Turbo selection for this amount of power is best selected between the HKS T04R series and TRUST T88 series. RE-Amemiya has always chosen TRUST Turbines and their selection for the Tsukuba Circuit version FD is the T88-33D 17cm. Keeping the secondary injectors as is and upgrading the primaries to 850's looks to be just enough at this power while keeping the fuel pressure right at 3.2kg/cm with the use of an upgrade fuel pump and regulator (in this case RE-Amemiya selected the Nismo Fuel Pump and SARD Type-RJ Regulator). Engine management is done through the HKS F-CON V Pro+e01. With the maps finely done and boost set at 1.0kg/cm2 along with a slight side port Aoki-san states that this is his recommendation for building a quality power and solid performing 500ps FD3S.
Obviously the boost levels could be higher for more power but the theme of the article is Get the Good Balance...
