Will my S366 support a set of 200/30's? or am I better off with just stage 2 160/80's? Im just about to buy injectors and I wanted opinions. I want to make close to 450HP. My Supporting mods are, TW chip, 4" exhaust, 6637 intake, T500 HPOP, 6.0 Intercooler, Electric fuel, Built trans w/ triple disk tc, and im considering head studs, valve springs, and push rods because my motor has 200K on it. What are your thoughts?
Definitely do head studs, valve springs, and pushrods if you want to keep it reliable.
Depends on the exhaust side on your turbo, but if it's spec'd like the S366 Jake sells it will run good with hybrids, but will need an external wastegate to keep back pressure down. If I was going to bother with putting an external gate on the turbo, I'd run 238cc or 250cc w/ 100% nozzles.
If you don't want to bother with gating the turbo, I'd run either 160/80s, 160/100s, or 180/80s.

Do you really think it would need to be gated Travis? I agree that gating it would help keep the BP down, but I think you could run that turbo without a gate and still be just fine. An S366 isn't that much smaller than an H2e is it?

With your mods and a s366 an 180/80 you could do 450hp and not worry about the WG
The S366 is the good choice if your looking to be right around 500hp. This turbo is an excellent match for stage 2 injectors, we have had this turbo and stage 2's make over 450rwhp. The turbo will flow 1100cfm and is a good turbo as well if towing or doing a lot of street driving.

If it had an 83mm turbine, he could probably run it without a gate, but the S366 most run has an 80/73mm turbine and a .91 housing. There may be a larger housing available that might help, but I don't know how much. In order to get the 83mm turbine, you have to step up to the S400.
The exhaust side on these turbos is tight, which is awesome for a towing turbo. Hell just look at some of the stock injector guys running this turbo without a problem. IMO, when you start asking for over 450hp from it, gate it. With 238-250's, you will be asking for 450+hp.
OP, the reason I didn't touch on the 200/30's is because I have absolutely zero experience with them. I would venture to guess that with the 30% nozzles, you'd be fine without gating an S366.

Hmm you make some good points. That's a little tight for a turbine housing. But for someone like me running measly little stage 1's, the S366 would be the ticket.

I just got mine done Chase, S366 with my stage ones. So far on my test drive it seems like it will be real good. I need to get hooked up to give it a better test, but so far, so good. Spools darn near as easy as the stocker.

Yeah, it's tight. I run a .90 housing on my S400, but since I have a little bigger turbine wheel in there, it flows a bit more exhaust than the S300s these guys are running.
I'm not sure how the 200/30's perform. I would ask your injector builder what they think. I think they would work great. They are hybrids, so they shouldn't use much oil. Hell they should be able to be run with a stock 17* being hybrids and having a small nozzle. Also since they have a small nozzle and only being 200cc, I think the turbo would be fine as far as back pressure is concerned, even with a .91 housing.
