![]() The 71 really is the ideal turbo for the EJ25 found in WRXes and LGTs. ![]() We recommend the 67+ for people with a stock block and it produces safe power levels for stock blocks, ie. The 67+ is designed to make around 350-400 whp on pump gas, and ~20 psi whereas, the 71 would make around 400-450 whp assuming supporting mods, and the turbo is the bottleneck. Both rock the same larger turbine wheel (TD06SL2) which has proven to be ideal for the EJ25 motor, so the difference is in the size of the compressor wheel and how much they flow or in other words how much power they can make. Size Choice: for the LGT fitment, we have arrived at two ideal sizes: the 67+, and the 71.Which turbo is just a question of how much power do you want, and do you want or need a ball bearing center section. This means you don't have to compromise with your turbo selection, and you can continue to use your other upgrades designed to work with the stock turbo like LGT-style flanged intercoolers. SteamSpeed fully supports WRX (08-14) and Legacy GT (05-09) with the same excellently designed and tested turbos for the STI in an LGT stock-location fitment.
