Subaru BRZ remap

The BRZ runs Subaru's FA24 2.4-litre naturally aspirated flat-four, producing 231 bhp from the factory. This is the same engine found in the Toyota GR86, built jointly by the two manufacturers and sharing its core architecture across both badges, a genuine platform relationship rather than a marketing line.

We will be direct about what that means for a remap. There is no turbo on this engine, so a calibration cannot open up boost the way it can on the FA24's turbocharged relatives elsewhere in Subaru's range. What a Stage 1 calibration can do is refine timing and fuelling, sharpening throttle response and smoothing the delivery through the rev range, a genuine but modest improvement rather than the kind of jump a boosted engine delivers. for the exact refinement achievable, but do not expect a large bhp figure on a naturally aspirated engine, and we would rather tell you that now than oversell the car.

Stage 1 calibration on the FA24 is a refinement exercise, honestly framed, and it is not the only work available. A standalone rolling road session, without any remap attached, is a genuinely useful option on a naturally aspirated car, giving you a documented baseline figure whether or not you go ahead with a remap. Economy remapping is worth considering for owners who want smoother throttle response for daily driving. Launch control coding is available on cars specified with it from the factory. We do not offer a Stage 2 programme on the naturally aspirated FA24, there is no supporting hardware pathway on this engine that would justify one.
