I have a 83 ar t4 outlet s366. I was wondering what size vband this is. I measured the outlet diamter at 3.25 and the size of the flange at 4.25. Do i use a standard 3.25 flange? I have read somwhere that you can use a standerd 3.5 vband flange and clamp. I dont know what to order.

 

You can't just get the 3.25" v-band flange because it is set at a different angle than Garrett or Precision. The S366 w/ the T4 outlet is a John Deere part originally. You need to contact Bullseye Power, as they have that v-band clamp & Flange available for that size.

Talk to Dave H. or Bill Devine

 

Its a 4.21" V band.

 

i have a bep s366 with a .91 turbine. what i did was weld a 3" v-bang flange onto the tubine flange.

 

Boner. I have a 366 in my hands right now and I need a weld on flange for my downpipe. Argh. Where is John Deere when I need him?

 

Order these from a John Deere Dealer

Special T-bolt clamp - Part # RE40048

Weld flange (80mm) - Part # R87732

You're welcome ;-)

 

I went to a turbo diesel supply shop, they gave me the right flange and clamp. Cost me like 30 bucks for both.

 

Holy frikken shizmofrakk

How the hell did you find this information? Thank you!

I also found them here:

Wow we are all running the same turbo. Awesome!

What are everyone's power goals?

I have a 1.9L miata. Only 4 other people have run turbos this large on Miatas before so I'm not sure how much power to expect. I'm guessing 25psi will get me to 580hp, 30psi 630hp? Dunno.

 

Miata cylinder heads are much different than honda B-series, despite similarities in displacement size. Time to just go to the dyno, get it calibrated and find out, at this point. Guesstimating just seems to give people false hopes.
