I personally have experience trying to make slow cars fast. The 1st gen Dodge Neon was one of the best handling cars of its era even winning a SCCA National Championship a few times; Mostly because Dodge was paying good contingency money and attached good drivers.Lmaooo why you gotta do me like that 😂
Anyway basic bolt-ons would make the DOHC version a low 14 second to high 13's second car and it had aftermarket support for serious parts like camshafts and pistons.
The Forte along with the majority of the Hyundai/Kia cars don't have that sort of legacy or support. So it ends up being throwing good money after bad when a Forte GT can run low 14's stock if you stop spinning the wheels off the line. With a few mods, it can punch above its weight.
You can't claim ignorance or some other reason for not knowing the GT existed. Kia makes the DCT free (no charge option) and the enthusiast pay extra for the privilege to have a manual transmission. in other words it's made for the low information customer, no excuse not to buy it other than it's out of your budget but that's hard to believe.
