I've seen and heard of guys running the S366 but don't know where to get one. What are the specs? I've heard 66/74/14..is that correct? Are they a quality charger? Streetable? Affordable? Any input is very much appreciated..thanks guys

 

There are a bunch of places you can get a 66mm s300. And price varies widely depending on where you get it. That also changes with way it is set up. It can come with a variety of exhaust wheels depending on who the builder is as well.
You can get a box stock Borgwarner s366 for around $1100 from AGP turbo. It will have the 74mm exducer, and a .91 A/R T4 housing. Bullseye power also sells them, as do, Industrial injection and HTT.

Honestly, I would be looking at a 64/71/14 if I were going to be running a single with your fuel. It will spool much better than the 66 will, especially if you go with a 66 with a T4 housing.

Reason I'm looking at a 66 is because I'd like to step up to some 240's. Would a 64 be able to handle the fuel from the 240's?

 

I'm running 200s with my Industrial Injection super phat shaft 66, which is a 66/71/14 and it spools great! My truck is a dd and I tow around 20,000 lbs a couple times a week.
