Turbo sizing

[scrapecc]

I'm looking at my options for my turbo upgrade. This truck will never tow again so a big single is fine. I'm looking at the s366 but I can't find anything down in the .80 ar range. Should I get another housing and machine it? Or will the .88 ar t4 housing be ok? I don't want a ton of lag while driving around town.

So lets hear it from the experts. What do you guys think?

Have you checked out River City Diesel? They have two different options for S366 turbo kits. I also know bullseye makes an S366 with a .70 exhaust housing. You probably want to stick with a 3 inlet since there are V-band to T3 adapters, unless you want to do some custom fab work.

bullseye s366/71 with a .70 t3. Great turbo! you can also get a .76 divided t3 or .80 t3

.88 t4 is really hard to spool.

Ok, so i'm guesting I've got to get a t3 housing machined then? I know rcd sells what they sell, but the price tag is out of my range that I am willing to spend. I can fab what I need to make it work. I'm just trying to put everything together on the reliable and cheap side. I want to see if I can put something together that is around 600 rwhp for around 4k. (not including tranny). We'll see if I can make it happen.

So far i'm into all the parts I need for my reg cab short bed for about 1,200 bucks. I'm patient so this is probably a project for this fall or next winter.

what are you thinking needs to me machined?

Well nothing I guess if the t3 housing will fit over the 74mm exaust turbine wheel.

you can get it in 65,68,71,74mm wheels.

I'm able to find a s366 with a 74mm wheel. But they are all t4 housings. But super cheap. You can get one of those for under 900 bucks. But the exaust housing is too big. But I wonder if the bigger .91 split housing with a diverter valve on it would spool quick.

Would a s366/71/.70 need a gate, Matt? Thanks.

From what I have been seeing on fuel you will be fine but if you want to spray you will probably need one depending on how much fuel you have and how much you spray.
