: 50lb. MSD's with 100 shot?

I am planning to run a direct port 100 shot wet system in my 1994 G20 with the 10:1 JDM motor. I would like to run the 50 lb. MSD injectors and JWT fuel rail that I have awaiting my winter turbo conversion and I thought why not throw them in now as an extra safeguard, but the question is how do I control these and I don't want the JWT ECU yet. Will an S-AFC work for the meantime. I am also running a Walbro 255 lph already and am planning on installing a MSD 6AL. Also, which plugs would anyone recommend for this setup. Thanks

As long as its wet direct port, you'll be fine. Adjust your air/fuel with the S-AFC ( on a dyno please :D ), then just spray it. The wet kit injects a stable air fuel mixture.

Although a 100shot is kind of big, and I can't offer any warranty claims here :D

Are you saying not to even put in the 50 lb. MSD's and just use the stock ones and get it tuned well before I spray?

You can do it either way. Put the injectors in, tune it, and spray, or wait for your turbo. As long as you've got the injectors leaned way out to a good a/f ratio, then you're fine.
