I got a Nos kit about a week ago and everything is good. I am worried about blowing it though. I am spraying a 75 wet shot. I bumped up fuel pressure to 45 psi and im trying not to be too trigger happy. People tell me to tune it, but wat should I do. I also have i / h / e and pulleys + MSD wires. Also im getting a msd 6a + blaster coil. Iridium spark plugs are bad? or not... Please help!!! btw its a 5th gen.

 

If you tune it you should be okay. my buddy has had a 75 shot on his car for the last three years and his car runs fine. ah yeah he goes through atleast 1 bottle a month

 

-ditch the iridium plugs asap. get plugs that are two steps colder. Zex makes plugs for the prelude that are already at the correct temperature setting. or you can use NGK plugs. just search for the PN.

-get something to retard your timing. MSD ignition box with timing retard is common.

- get that thing tuned. when it is tuned properly you shouldnt see any fluxuation in your fuel graph from with and without spray. that is why you have a wet kit.

- i suggest getting a new fuel pump as well. a walboro 255lph is the common.

- clutch. your stock clutch will be going bye bye very soon.
