You can add all the mods you want, be John Force. But if your car is not putting out 425 to 450rwtq. I wouldn't destroy the car trying. You'll need a healthy strong running car first and foremost. This is where the number is so small in persons who have achieved this great time. As many know most stock turbo Z's have their factory install turbo's still and miles over 100k. So compression and Turbo failure is a top concern when asking so much performance out of the car. Things to remember are the cars weights in 3500lbs ( avg. ) plus the weight of the driver. They have a squatting suspension system that is made for autocross more so than drag racing. Plus if you have all these things your still going to need things like, a good prepped track and a good 50 to 60 degree night helps.
