my turbo build will begin next month... just getting together the last couple little pieces i need... but my hold up right now is what injectors to go with... i'm going to be running a single 68mm turbo set up. i have a local guy doing the turbo for me. ( was in hot rod magazine for quickest 6 cylinder *white camaro running 10.60's* :eek: ) pretty sweet... but bottom line is... he knows the ins and outs of the turbo systems. but i know you guys will be much more helpful with choosing the proper injectors. i plan on running around 8 PSI... thank you in advance for any help

what about brand...? any tips? i've been shopping around the internet for a couple of weeks now...
Ford 80's and 1 step colder NGK iridiums are what I run. Make sure to gap them down around .030 or even tighter around .027 for 10+psi.

I thought that for every 100 hp you make you need to go one step colder on the plugs Chris. So shouldn't you be going to 2 steps colder maybe?

That's just a general rule of thumb. Harrison runs the same plugs and has made 865 with no spark blowout. If you gap them down tight they are fine.

so... would it be a "safer" bet to run the 2 step colder plugs? and i guess what difference would there really be in running the 2 step colder compared to the one step gapped down?

What you doing for Fuel pump ? I run Brisk RR14's ( Two step) Gaped at .32 , I would go 2 step as you would want to crank that bad boy out for sure .

ok cool... now would they have disabled that hob switch or just completely removed it when they took the s/c off? i do remember the dealership saying i have above average fuel pressure. if i need to get one... any suggestions?

It may still be hooked up but obviously wouldn't kick the 2nd pump on without boost. Look for the round black switch wired in near your battery. That's usually where it would mount.

It would probably be near the firewall on the driver side and would be connected to the brake booster hose and would be tapping into a splitter.

Correct me if I'm wrong but the fuel pressure is unrelated to the number of pumps and entirely related to the fuel pressure regulator. Additional pumps just allow you to maintain pressure, the fpr controls the pressure.
