I don't know what your talking about. Put the same motor on the NTC3 that is on the 4-tec and you would go just as fast if not faster after changing the gears. Speeking from experiance, if you are looking for speed out of the box and that is it for running in a parking lot, go with the 4-tec, I did, but then I wanted to control the car. I went with the NTC3. I changed the gears in the NTC3 and put in a Rossi Pixi Black. 12. The car now will hit 60 easy. The last race at the sugar bowl in Ga, on the OVAL, ran a 5.280. It averaged 47.7mph.....that makes a strait away speed around 60-70mph If all you people out there have a touring car for speed, bring it to an oval track. after all, what do you do in a parking lot.
