Didn't know where to post this so I put it here. Anyway, I want to buy the NX throttle switch activated import stage 1 nitrous oxide kit (Adjustable from 35-50-75 WHP) for my '93 Civic. Here's the link to the product: Honda Civic Nitrous Express Import EFI Stage 1 Nitrous System at PRO Civic.com . At the bottom it says for a 50 shot you should buy 2-step colder Iridium spark plugs and upgrade ignition, for a 75 shot that you need the plugs, "definitely upgraded ignition and plug wires", retard ignition timing by 2 degrees, and possibly a stronger clutch. Does anyone know for sure or have any experience with nitrous on a pretty much stock (intake, header, exhaust) D-series and know what else I should get to run a 75 shot if anything? I'm not planning on using it a WHOLE lot, just when I get really pissed and need to relieve stress or occasionally to have fun and surprize mustang owners . Oh by the way, do flames really come out of the exhaust like in the movies? Haha that's a serious question I've never actually used nitrous.
