what do lifters have to do with it's ability to make power?

will you be using the stock TB or going for a 65mm one?

In normal applications a bigger TB doesn't really do much. However, in the JRSC's a bigger TB does make big gains, so go with the biggest that fits.

I already have a FC 65mm TB. It's just been sitting in a box. I keep forgetting to order a Focus throttle cable. BTW, I've also been toying with idea of using a 4.6L Mustang 70mm TB. It's the same one that Ford Racing uses on the FRPP intaks manifold. If you're gonna go big, why not REALLY big?

I'm wondering that too. If anything, the boost will help push the valves open. I'm not going over the stock rev limiter either. Is this some old school V8 myth?

The down side to hydraulic lifters;
Hydraulic lifters have a greater chance of floating at high RPM's and under high power applications ("valve floating"). The chances of floating goes up with wear on the lifters. this means that you have to back off the power a litle bit at high RPM's. Shouldn't be pushing the Zetec past 7K RPMs much anyway, so it shouldn't be a problem.
I'd suggest solid lifters if you're going big power and/or high RPM's.

I wouldn't even push 7K rpms boosted. It's not just the valvetrain, it's the Rods. The stresses on stock rods, under boost, are approximately 30% more at 3000rpms, even with double the HP. At 6000rpms, though, the stress are multipled so it's not double the stress it's like tripled or more.
That's why I like turbo's cause you get all the boost down low, in my setup anyway, where the rods can handle the stress easier, but the JRSC only gives full boost up high where the stresses are much higher. On the upside, I hear it can be easier to tune a SC since the main power is in the upper RPMs so timing and fuel is easier to dial in right.

Yeah, but you really didn't have any power.
