What rating should i run for my new Fuel Pump?
What PSI should the regulator be set at? With boost compensator correct?
What special things should i do to my ignition setup for my turbo?

Which search button have you tried?

lol.
Maybe he should open up a thread on "How do I use the search function", and what is it used for"?

yeah with dial up it takes me 45 minutes to find an answer, the search button on site seems to be too vague.

I was looking at a walboro 255 pump and that seems like it would be more than enough to sufice my turbo needs.

Still havent found out exactly what rating i need my regulator to be with my 7-10psi turbo for my 12a. A good link to a site or exact specifications would help.

I've been searching for nearly 3 years, haven't found all the answers yet either. So I guess dial-up will take you 9-12 years. By that time, you could read the entire forum and actually learn something.

Walboro 255 is a good pump, more than enough for a 12a turbo. I use the mallory regulator on Robert's site(www.rotaryshack.com). Any regulator with a vacuum/boost port on it will work, for a simple turbo setup get one that goes up 1:1(1psi fuel for 1psi boost). If you're running a modified nikki carb then set it at 4-5psi at idle, around 7psi if you're using a weber. You can use the stock ignition, but I'd suggest getting a MSD 6a box, 6al if you want a rev limiter. Get single prong NGK's and set the spark plug gap to .010 if you don't want the spark to be put out under boost.

you should explain this part "Get single prong NGK's and set the spark plug gap to .010 if you don't want the spark to be put out under boost." Why the single prong and what do you mean by the spark going out under boost?

The stock plugs are NGK's, but they're 4 prong and can't be re-gapped. If you're running 14.6psi then you have basically double the air/fuel mix you would have n/a. More air/fuel in the engine means higher pressures inside the engine, and it makes it harder for the spark to jump the gap. If the pressure gets high enough that your ignition system can't supply enough voltage to jump the gap, then it won't spark. The plugs I normally use in my car are NGK b8eg's, gapped to .010, I think autozone can get them, but I buy them from a motorcycle store. My friend that works at a Mazda dealership got me a set of rx8 plugs, the leading plugs are 7 heat range, too hot to run in a turbo car, but the trailing plugs are 9's, I use them in the leading on my car, gapped to .010, and they work great and seem to last a lot longer than the b8eg's.

Thanks, that helps alot. I understand the whole plug situation now, but i heard that you use single ignition? Or combined ignition so they fire at the same time or locked timing?
