Well, if you have to get the car anyway, you're gonna have to be realistic with yourself first: the Elantra GT will NEVER come close to what an Evolution or WRX will have to offer, not to mention the more tunable Japmobiles out there like Silvias, RX7s or even the last couple words in performance, Skyline and Supra.
All this aside, thats just on the dyno,and maybe on the strip...elsewhere, the driver counts for as much as a hot turbo setup or correct gearing,the driver is an integral part of the racing soloution, and with the right skills you will be competitive.
Start with tyres,what are others running on the course, and what works for them?Asking around in your area and hanging out with the folks who do the AutoX where you are can yeild plenty of useful tips,especially when it comes to gearing and shift and brake points on the track.Suspension setup will have much to do with how you drive the car, it WILL have to be dialed in to how you want it to be,and will doubtlessy be a major factor in what your results will be like, especially when you're looking for that last itsy bitsy iota of traction...
When it comes to the engine,it depends much on the track and how you're geared for it: will you benifit more from a quick-revving NA setup, or on-tap boost with a blower?Are any others running turbos on the course...and what kind of turbines are they using?Do they have antilag...?
Try following what the more successful competitors are doing, and tweak it round more towards how you want things to be, I wishg you all the best, and CONGRATULATIONS on the impending birth of your child!
