When you get the Nissan 240SX, keep it, do not sell it. If needed, use the master cheat for all the performance parts, you must upgrade this car to the max. First you have to change your cars' mode to drag, then apply these following parts:
Wheels-(any kind)set zones 2,3,and 4 to 100% on the rear wheels only, don't touch the front. BodyKit-stratospeed widebody stage1 and set zone to 0%, you need your downforce drawn toward the spoiler. Hood-any of course. Spoiler(needed)-gentera style 403 stage1 and set all zones to 100%. Rollcage stage2 and if you want, racing seats up to you. Next apply stage3 engine, drivetrain(important), forced induction, suspension, brakes, tires, and stage4 nitrous(if unlocked). Now your car is fast....But not fast enough, you have traction and speed but you also need...acceleration, no one told you about that huh! I have setting that will make you unbeatable, your car will perform over 1000ft wheelies with max speeds up to 235mph, make Karol Monroe look like a wuss. Here's the best part, Tuning:
Suspension-rear shock compression rate set to stiff, rear shock rebound rate 5 notches to soft, rear spring rate set stiff, ride height to low, rear roll bar stiffness 5 notches to stiff, rear tire pressure set 7 notches to low. Engine-start boost to high, nitrous pressure 5 notches to high, and now the Drivetrain gear ratios. Each gear is adjusted a # of notches from the center:
1st gear 7 to short, 2nd gear 5 to short, 3rd gear 2 to short, 4th gear 2 to tall, 5th gear 6 to tall, final 7 to short.
Now you must remember two things, hit nitrous at 4th and no missed shifts and your newly improved dragster will hold a wheelie all the way to the finish in a quarter mile drag. Hit nitrous at 5th gear in half mile drag.
