so ive been doing lots and lots of reading over this summer trying to get a good idea of what i should and shouldnt do with the gf car, first thing we are going to tackle this winter is spark (its a 84 SE just for future reference) and ive been weighing the options of a MSD 6A or a DLIDFIS set up. I like the MSD for fact that it would be clean, simple, and straight forward and i havent read about anything that says i shouldnt. On the other hand the DLIDFIS set up uses GM ignitors which take place of the crappy stock J109s that cost about as much a good liver on the black market, but its a cluttered set up in which you need 3 coils and some way to place the three ignitors and extra wiring. Does the MSD get rid of the J109s so to speak? thats pretty much the deciding factor as they will both cost about the same for me, also with the MSD box i could just run off the two leading spark plugs and forget about the trailing as ive read the trailing only do about 10% of the work. i just want to get all of this cleared up before i start in one direction and i should have gone in the other.

thanks
Zak

 

and another thing i forgot to ask about is if i did go with the MSD 6A could i use a FC coil for the leading plugs then use a MSD blaster2 to run to the dizzy in place of the leading socket and run the trailing plugs off the distributor?


its a horrible picture i know but i hope it gets the point across and both coils will be off of the MSD box just fyi

 

There is no horsepower benefit to running trailing. People have dyno'ed with and without trailing, one right after another (with proper cooldown time of course), and saw no change in power.

I would go with the 6AL if you go with MSD, for the rev limit function. I have MSD coils run off of the stock dizzy and ignitors and noticed that it was much easier to start the car (absolutely no changes anywhere else when i wired in the MSD Blaster 2's).

Lots of people run the DLIDFIS and love it. I just had the MSD's from my old FB (the PO had them installed), so I wired them in.

 

i figured the 6A because the ecu has the rev limiter even though the soft touch ignition rev limiter is alot easier on the engine

im just trying to weigh the pros and cons of both set ups but i like the simplicity of the MSD system but the DLIDFIS system seems to be the cats meow

 

i use to have a 6AL box, but i've had better luck with 2gdfis actually

whats that little restaurant on main street in seward, close to the aquarium? best damn clam chowder evar!

 

oh man we're talking 5 different restaurants easy the one closest to the aquarium is Cristos then going up the street it would be Alaska Nelly's, Thorn's Showcase, Apollo's, and i cant remember the name of the last one

but thanks for the input guys

also i bought one of these to install with the new upper and lower radiator hoses and i didnt realize it until it got here the tube looks a little restrictive, im assuming thats not a good thing?

 

Apollo's is the one. damn good food! i'm thinking about taking a trip back up there this summer. if you need "local" help with your car, Nick at Underground Performance (in Anchorage, right across from the Merril field tower) is real good with them. ( www.undergroundperformance.us )

 

i know the shop and funny thing is i never thought to call and talk to nick about some stuff lol next time im in anchorage i might have to do that

thanks for the input

 

i know he's good with em! when you go, tell him greg (the guy that bought his first gen) says hi!

 

alrighty will do!
