Default turbo guys need alittle help

I got a 99 gs 300 Im finishing and I need to know what plugs to run and will the stock plug wires hold up. Ive got some NGK BR7ES's but the base is to big (21 mm), is there a NGK plug the same as the BR7ES with a 5/8 base. And the wires Im just unsure of... My set up is dual BB T66, RC 555s, S-AFC, FMIC, 75 shot, thicker head gasket, stock bottom end, 12 to 14 psi on 93 pump. Hopefully running by the end of the week

Do you think 555's are going to be enough for a T-66? Why not 720's, at least. Dual walbro intank pumps, 4row fmic, port the head with some hks 264 cams. As far as plugs go, Iwould use irdium.

Well the RC 55os are enough when you cant run but 12 to 14 pounds of boost because the stock bottom end wont hold much more. Its a 99 model with 30k, when the car needs the rebuild Ill build it to hold 25+ psi (that what the compressor maps say the turbo is good at). Now Ill be in the 500 to 600 hp range @ 10 to 14 pounds of boost. @ 25 pounds the turbo should get it into the 700s RWHP. The FMIC thats on the car now is HUGE so thats not a problem, head work, cams and injectors I can see needing somewhere down the line. I already have a Haltech E6S-8, MSD and a few other goodys for the next step, Im just not yet ready to pull the motor. The fuel lines, rail and pump are all good for 1000 hp so that one part of the set up thats not going to hold me back. Thanks for the feed back, the more the better.
