A cookie-cutter super-safe JWT ecu has powered a pair of notable stock block KA's for years (one for 4+ years) at over 1 bar of boost. That's 350rwhp@15psi for one, and 360rwhp@15psi for the other. With a SS rom tuning, you'll have a custom tuned ecu to run more power, more timing, and still be safe. It's a good time to have a KA-T
These 2 cars simply installed the turbo kit, ecu, fuel and a boost controller and cranked it. The KA can be a healthy motor, just don't skimp on fuel or maintenance.
