This past weekend we were at BIR Octane Autofest. Saturday morning we had the shop RS in the autocross event, resulting in a 2nd place finish!🏆
Last week we put in a different suspension setup and it handled everything very well
More results from this weekend on the way🏁
Not every project that comes through our shop is a high-horsepower build.
Paul's latest Tech Talk features a Subaru Outback getting a remanufactured engine.
The owner loves the car and decided it's worth investing in keeping it on the road.
From daily drivers to performance builds, we help Subaru owners get the most out of their vehicles.

❗️FRIDAY FEATURE: Rahim’s 2024 GR86❗️
Built with an HKS GTIII-RS bolt-on turbo kit featuring the iconic T51R mod, paired with a full flex fuel setup from Delicious Tuning including fuel pressure and boost control upgrades.
Supporting mods include ID1050x injectors, DW300C fuel pump, Omni 3 Bar MAP sensor, Radium catch can setup, and an AEM oil pressure gauge for added reliability and monitoring.
Finished off with a custom flex fuel calibration in-house by JM Auto using ECUTek. 🔥
First time ever on this track. Definitely sloppy run, getting used to new power band on lower boost still. Will have new coilovers installed before next track weekend.
Lol and launch control is still set to low for the turbo size.

Fun weekend with many highs and lows at Blackhawk Farms Raceway!
Lots of highs and lows shaking down these two cars. Long way to go to have them completely ready.
But very proud of the team! The JM RSTI went on track on Friday for nearly 8 track sessions. Then Saturday another 4 more in the morning and standing start in the afternoon! The amount of abuse this car withstood is a statement to progress and quality.
The JM 24 WRX on the other hand had some cooling issues and will be back to the drawing board! After new ARP head studs and upgraded radiator the airflow just was not there. With the large intercooler and oil cooler we are needing some hood vents to allow more airflow. So this hood will be getting cut up and prepared for our next event for more testing!
Will post a few videos tomorrow.
Dyno results for Jay’s 2020 STI are here! Pushing over 880hp and nearly 700ft lbs of torque, this should make for a fun car on the track! 🏁
