Why not do the toggled vss trick? and unless you got some serious mods there isnt any point in trying to wind that motor out in 4th, it will take a long time to climb up there and then it will blow, prolonged high rpm added to 3100 with no oil cooler plus heavy car that probably still has a cat = high temps. high temps = kaboom. unless you are fast enough to max it out in a quarter, you are gonna burn your bearings up trying to get up much over 120 or so. If you dont scorch the bearings the tranny is gonna cook man. you dont wanna do that to a 16.5 second car, its for getting groceries, not racing.
