i want to start prpping my engine for nitrous and i know i need tr6 plugs and a good ignition system like a msd 6a. my questions are if i install the tr6s in my car now, what would happen, good and bad? and my other question is how do you hook up a msd 6a to the ignition coil?

 

it'll be fine with tr6's now,no worries.

MSD sells a plug-n-play harness for hooking up thier boxes.

 

it wont do anything, like less fuel economy or something like that?

 

you might lose .5 miles to the gallon,my car still got 24 highway mpg with tr6's.

 

i'd get msd6al for nitrous not msd 6a,
I'm not an expert by any means but, if you get 6al you will then get the msd revlimiter which cuts out spark, as the stock computer rev limiter cuts out fuel which is a no no when spraying the juice...

yes it cuts the spark. you will also want to have someone program out the stock rev limiter. i would run the digital 6 personally. spend the money, youll be happy you did.
