Zex question
I have a civic with a GSR swap, the motor is an 2001 and has about 30k on it or so. I was wondering for a zex 75 dry shot what i would need to do to not have to worry about retarding the timing or is there no way to really do this without having to worry about problems. As of right now i run 93 octane gas. If i ran 94 octane gas would it be safe or if i had 94 octane gas and some octane booster? just wondering cause id rather not have to retard my timing and have crappy performance N/A. Im thinking about getting the MSD SCI+ but im not sure if i will end up being it. Any feedback ideas or anything would be greatly appreciated.
Thanks
Matt

I'd get the MSD SCI+. I'm running the exact setup I think you want to be. Right now, i'm running my ignition timing at a 2degree advance all the time, so therefore if I want to run a 55 shot, I set the ignition to retard 2 degrees so that it brings it back to 0 when running nitrous. right now I have the 65 shot jets installed, so I have my SCI to retard the timing 4 degrees, then if I ever wanted to go w/ a 75 shot, i'd retard it 6 degrees. if you are gonna run a 75 shot, DEFINATELY upgrade your fuel pump. I got a Walbro off ebay & it rules. the ZEX site says you don't have to, but it's just a good idea. Also, if already running a 94 octane fuel, octane booster isn't gonna do jack. It might bring it up to like 94.3, but nothing noticable at all.

Your stock fuel pump will be fine. In addition to retarding ignition timing, make sure you run one heat range colder than stock, copper plugs, and gap them around .030" since you'll be running nitrous....I run NGK BKR7E plugs in my car. Octane booster doesn't do anything good, and it leaves deposits in the injectors and such.

I'm a little sketchy on platinum plugs, I've heard of a lot of people melting them while spraying...just an FYI.
