s366 turbo Specs are 66/74/16 .91 a/r with nongated t4 exhaust housings. Exhaust wheel is clipped for added flow.

Also how much would it cost for a waste gate and what would yall recommend?

I am also running factory injectors guys. I plan to up grade to 150 hp when I find some.

So is would this be a good turbo for me? its a daily driver and pull sometimes but not competition.

I don't have any mods on hardware on the motor.

 

You'll need more than 150's, a Smarty, and a juice to spool that charger. If you want to run 150's, a Smarty, and the Edge and still be able to pull stuff I would look into something around a 62/12. JMO

 

so what size of injectors would u recommend if I got this turbo ? so ur saying it wouldn't be a good towing turbo?

 

No it wouldnt. Way too big for towing. Unless your towing a sled down a 300 ft track in a lower class.

To spool that turbo you'd need 200 hp above stock injectors and a Smarty and prob still not be getting full use out of that turbo.
It will be waaaaay laggy causing you to black out intersections and egt's to soar before you get enough air to run well.

I would say a 64-71-14 max size for towing. And even with that size, youd still need a atleast a Smarty or Juice or something to help with the 150's.

Keep your juice and smarty, get some 150's and something like 62-71-12 will be a little laggy, but flow good air, keep temps down, and prob be just about right.
Coarse with any more then 45 lbs boost, put in head studs!

Before my compounds, I would tow on a daily basis with 150's, My Juice on 2, and my D-tec 62-65-12 keeps up just fine.

 

With the T4 housing, you'll need an exhaust manifold to fit the big flange like the ATS Bigfoot.
I don't like adapters, too big a change in flow direction and speed.

 

GT3788R stage 3 would be lots for 150 sized injectors. Who's injectors you planning on running? I'm just running a stage 1 on my 02, its lots of turbo for my little 110's sticks. If your towing, twins is the only way to make them work.
