I will be ordering a zex dry kit today. It is adjustable from 75-125 hp. I just had a set of motive 4.10 gears put in last monday and I love them. I will be installing my speedcal this afternoon. I just tried to not drive the car as much because of the unwanted extra miles. My car has 40,000 miles on it right now. My current mos are as fol mods are a mac catback and k&n drop in filter, motive 4.10's and a steeda tri-ax. I am going to run the 75 shot through the car. I got an excellent price on the kit and I had to buy it. I plan on upgrading all of the usual bolt-ons but, I have to buy school books for this semester so I will just have to wait. Future mods will include: mac prochamber, c&l plenum, c&l intake, and a bbk 75mm throttle body. All of my suspension is stock right now so I will be upgrading it as well. I had planned on getting my bolt ons first but the price for this kit was very good

 

good deal i'd go get a speed cal to correct the gears b4 anything......or a tuner. School before your car though I learned that the hard way.

 

I ordered a speedcal last week and it should have been here today but I guess I will have to wait until tomorrow. School will always be first. I just had some extra cash and I was ready to mod again. It's addictive!

 

I guess your running a stock tune? Just a word of caution....running Nitrous without a custom tune, or at the very least, a Air/Fuel check on the dyno is very risky. Many have lost their motors due to an unknown lean condition. Contrary to what you may have heard nitrous is not "Plug and Play" :bash: Just not worth it IMO

are nitrous and 4.10s a good combo????

 

Depends on if you can hook it or not.

 

As with any ratio change that's adding to the torque multiplication, you'll come up on redline a lot faster. You'll want to have RPM windows switch and pills to cut the nitrous at like 3000 5200. Do not bounce off your rev limiter with the nitrous running! You'll walk home.

4.10s are a good gear in general. I'd probably leave it at 3.55 or 3.90 but I'm really conservative.

Running nitrous in any amount without a tune is plain silly. Sure lots of guys get away with it, lots more have 256,000 piece intakes and vented blocks because of it. Get a tune and that'll take care of the speedo too. If you don't know for certain your A/F under WOT with nitrous you're taking a chance of walking home.

 

Not sure, but doesnt the Zex systems have a computer that adds or subtracts fuel so that the mixture never gets too rich or too lean??

 

it adjusts only to bottle prssure not ot the cars air fuel ratio. so its just making the kit work better not safer for you. I will say a tune is a good idea but i am one of those guys who dont have one and run a 125shot have been threw 9 bottles with it so far. But i can read plugs and have fuel upgrades so i am bit better with this then most people are.

And 4.10's and spray are good if you have trraction like said before without your gonna be loosing time do to tire spin. Mine spinds pretty hard in 1st as is with a 125 on dr's and a stock rear end.

 

The intake design and plastic construction on 96-04 GT's isn't good with wet kits. You can get pooling of gas at the bottom of the intake and eventually you will blow your intake into a meeeelion little bits. Keeping the minimum RPM above 3K helps keep that from happening.. just don't engage the gas till you've crossed 3k.

Spike... 125shot? wow... more than I'm used to seeing. Leaves tire marks in 3rd gear I'd bet.

 

No it hooks pretty good. I run lakewood lowers and 275/40/17 Nitto Drag radials and i have a stock rear end so I only have really bad spin in 1st gear then it hooks pretty good in 2nd and 3rd and 4th just bit hard. With stock 245's that i barrowd from a freind it spinds pretty badly into 3rd gear, which is pretty fun.

 

I don't know what traction is like from a standing start.. I have 275's street tires on back and they're spin material till 3rd gear on motor (250rwhp) if I shift hard.

I do have 300# rear coil overs though so I expect to have lots less initial traction... it corners like a slot car though.

 

ahh handling thats what these things are soppose to do right, lol i dont really care about corning i live in florida where we have no turns just straight roads so i am more into going fast in a straight line. My next suspension mod will be either steeda or Eibach drag springs.

 

handling... what they're supposed to do... naw! They're supposed to have a lot of power at a minimum of cost wrapped in unremarkable styling. Serious.. that's the market up till the 05's came out... which upscaled it a tad but not much.

In any case, I see your point for your case.

 

Yup, just like they said earlier...get it dyno tuned, and stay away from the limiter!
I got mine tuned for a 100 shot and I set my limiter to 6500 and I shift at 6000, and I haven't hit it yet...(knock on wood), but with a wet kit it isn't nearly as dangerous as a dry(bouncing off the limiter that is).

 

well, I have decided to stick with the all motor route. My main goal was to reach mid 13's. I have ordered a few more goodies and canceled the order on the nitrous kit. The new parts are as follows: K&n fipk II, 70mm throttle body, upr plenum, and a sct 4 banks chip. I am still undecided on the mid pipe because I love the way the car sounds now with the mac flowpaths, I know I will get better gains with an off road midpipe but I dont want the car to be too loud. I am trying to search for a car with the mac prochamber on in because I want some sound clips.

 

I have a MAC Pro-Chamber on mine with a Magnaflow cat-back. Trust me, you won't be disappointed with the sound. I don't have any sound clips right now, but my friend might and if he does, I'll PM you the link to it.

 

What tires you running in the back? I suggest you be carefull untill you can replace the rear axles cause youll deffinately snap them with the combo your running.

 

darn right it is.... nitrous loves the gears!

 

I'm on the stock axles with just 3.73's and mine's fine so far (knock on wood). Best 60' is a 1.73 on the bottle and a 1.84 on motor.
BTW: that was on Nitto DR's with about 15 psi in them.

 

well its a hand toss some times they hold for awhile sometimes they die.

Mines got around 100 passes on them and tons of street launches also and they are fine. with 275 nitto drags and a 125shot out the hole.
