I'm thinking about installing a zex ket into my 04 Mach 1. I was curious if anyone has done this yet and what shot they are using. I want to put a 150 shot in it but I want to make sure the motor can handle it. For the most part the car is stock. I only have an intake, full magnaflows, and msd coil on plugs.

I would stay a bit safer with a 100 shot. Also an adjustable tune for the nitrous would be a great addition. Other saftey features you should invest in would be a window switch and wide open throttle switch. That will keep the nitrous off until you are at WOT and between the designated rpm range that you set in the window switch.

I have a zex wet and have hit it with 175. Zex shot are under-rated. Their 175 is same as nx 150. For a shot that big you need to retard timing 4 degrees and up the wot fuel. Both can be done with a tuner. I have a complete zex kit for sale including purge and msd digital window switch. Great system

K. He said zex. The brain box is a the wot switch and you don't need to do anything with 100 shot. The computer compensates instantly for the added oxygen. You need a tuner for sure. My sct does everything you need. 125 needs 2 degrees retard. 150 needs 4 degrees. 175 needs 6 degrees and wot maxxed out.

Thanks. I was def going to get the sct tuner before I ordered the kit as well. What are u selling your zex kit for?

From prior experience with nitrous on any motor i would definitely go with a supercharger as a power adder. I dont care what anyone or parts salesman says nitrous is very rough on an engine
