94 GT nitrous questions...

[JSFIRE79]

I run the 125 shot off a zex kit in my 93, and I used to use the autolite 23's gapped at 35.. car ran very reliable with 160,000 miles. I now have different heads and cam but still running the ZEX for a while... My suggestion is this start out using a colder plug and keep your timing at 10 and run the 75, then pull your plugs ( not just one) and read them...if they look good bump up to the 100 ( I always kept my timing at 10 for this) but lower yours to 8 and then repeat above......if all is good then hit 125 if it's all good after the run bump your timing a little... bump it a little bit at a time and see how it runs.....if your MPH is going up you should be alright if you start leveling off or drop then lower it back down. I ran 16 degrees on 110 race gas. with the 125 shot ran beautifully but I also had the fuel system and GT-40 heads and a Nitrous stick...Just rememer to read your plugs even at a 125 shot...
