86/BRZ Turbo Guide
So you want to turn the power up on your FA20 powered 86/BRZ? Which turbo kit is for you? Before Racefix Parts was conceived I went through the exact same process myself. As I dove deeper into the world of turbocharged FA20’s the answer became more and more clear. Sydney Motorsport Engineering.
SME seemed to have it all right. Cheaper than the competitor kits, hand made components made out of a shed in Sydney, Australia and whilst their turbo sizing seemed obscure compared to other manufacturers a quick glance at a dyno graph quickly showed how lovely the power delivery was on the G-Series turbos. Hand made stainless steel exhaust components, mandrel bent aluminimum intake components, a clever and well though out intake (instead of the hot air intake others offer) and an awesome power delivery with a very high ceiling for peak power? I was sold!
So which SME turbo kit is right for you? We have 4 off the shelf turbo kit options to satisfy essentially every need in the 86/BRZ chassis. Check out the comparison graph below for a visual representation of how each turbo responds.
Our FBOMB kit is the entry level way to boost your 86/BRZ. It features an oil cooled turbo utilising journal bearings. Whilst it isn’t the forefront of turbo technology it is more than safe and capable of some happy laps on track whilst copping the miles of a daily driver or the fun weekend car. It is still possible to achieve some fairly high dyno figures with the FBOMB kit however it does so at fairly high boost pressures. Looking for more? Lets dive into our G Series turbo kits!
Our G Series kits are the next step up with the G30-660 being our flagship. These kits feature ball bearing turbos with water and oil cooling. The larger nature of the turbo’s allow for more peak power but also allow for a more track friendly power curve bringing the torque in a little later and more linearly.
For predominantly street driven cars we recommend the G25-550 as it brings the power in a little earlier and harder. For track driven cars we recommend the G30-660 as the torque curve is a little lazier and much easier to drive and modulate in a track setting. The later torque will also keep the engine internals and gearbox components happier for longer in a track car.
For the street car that will see the occasional trackday on E85 we also offer a G25-660 which splits the difference retaining the lively nature of the G25 power delivery with the linear torque delivery of the G30.
On a standard, unopened FA20 all 3 G Series turbos will see very similar peak power at the same boost levels.
