Australia’s First Turbo GR86/BRZ.
Well she’s finally here - Australia’s first turbo FA24 GR86/BRZ. To say this moment is a long time coming is an absolute understatement. We originally test fit an SME turbo kit to a 2022 BRZ almost 12 months ago to the day. Since then we have waited patiently for the PVS BRZ to arrive, ECUtek to release software and Mike from SME has been squirreling away making the necessary changes to the incredibly capable SME G-Series turbo kits to build a production kit to suit the new 2.4L equipped GR86/BRZ twins.
Before you ask, no, the kits aren’t compatible with FA20 powered cars and the list of unique components is quite long including updated sump, updated intercooler and intake piping, updated dump pipe, updated oil feed, updated water lines and ofcourse updated bracketry including some relocations of factory brackets.
Checkout the YouTube video below for some details on the kit, power runs and ofcourse power output before heading back here for a deep dive.
Welcome back, you’ve now learnt that the new FA24 is INCREDIBLY efficient in making power and torque - perhaps unsurprisingly but I don’t think anyone was expecting almost 400Nm (295 ft-lb) out of a standard clutch and injectors on a 98 octane tune (93 RON for our American friends). Whilst this may not sound like alot its 20Nm more than #project86 made on it’s 10PSI G30-660 E85 tune which is incredible.
What is the power gain?
Since we shot this video on Wednesday night Tyler has spent hours trawling through the BETA ECUtek software perfecting the tune coming away with 236kW (316 HP) and 386Nm (284 ft-lb) at 8psi on the standard clutch and injectors on fuel and timing numbers that would be safe as a daily driver, weekend cruiser and be more than safe to thrash around on the odd trackday. Whilst these aren’t huge numbers it’s only the beginning and the new FA24 is showing huge potential to elevate the 86/BRZ chassis even further. Just incase I haven’t said it enough this is on the factory clutch and injectors. The FA20 powered cars were always very welcome to modification but equipping a standard car with a clutch and injectors that will do these kinds of power numbers is incredible. Even on most factory delivered turbo charged cars and increase in torque of over 150Nm would require an upgraded clutch and injectors. Subaru has certainly looked after us here. For reference the redline is the same car on it’s standard power run - 153kW (205 HP) & 232Nm (171 ft-lb)
How does it compare to the FA20?
Below is 3 power runs overlayed. The solid green line was a 9psi run that Tyler had to roll out of due to the fueling being on the lean side. Solid orange is the 8PSI run reffered to in the video and the dotted red line is an FA20 car with a G30-660 on a 10PSI 98 tune. You can see that even with less boost the FA24 greatly out performs the FA20 particularly between 3500-4500rpm. I cannot wait to see what the numbers and power curve looks like with more fuel and then E85!
If you have any questions at all regarding this info or turbocharging your 86/BRZ please don’t hesitate to reach out here.
In the coming weeks ECUtek will hopefully release updates to it’s tuning software to allow for injector scaling so we can flick the car onto E85 and really see where the party is at before road and track testing the car extensively. It’s pretty awesome that we could supply a customer with a turbo kit tomorrow to go into PVS and drive out with a power increase of 80kW and 150Nm for a smidge over $10k supplied, fitted and tuned while retaining the standard injectors and clutch and the ease of 98 pump fuel. Exciting times ahead for sure!
