I'm hoping they don't keep it ESS only installed because I want to do a full engine balance and build. I suspect they might plan on tuning them on a per car basis though.

For stage 3 pistons are required and depending on the power rods also. You will also need an upgraded clutch. Cats will be optional but we recommend runing a euro spec exhaust system. Stage 3 will only be available for cars that come to us for installation as proper installation and tuning is required on each car.
Pricing has not been set on stage 3 yet. We are hoping to deliver the stage 2 kits around $8k-10k depending on spec.
