Hi, I have now a 2500 with the hy35. Back in my turbo buying days I bought these 2 turbo's which are brand new. Would this be ok the build twins?

S300S046 from a john deere 6.8

Thanks for the help

 

what are the specs on the 2 turbos?

 

The 2nd one if you have to use one of them.

 

do you know the specs?

 

that's the question no Idea...

I was going to try the s300 and s400 as a couple

 

yea if they're s300/s400 based, its a good chance they'll work together, but you need to pull the covers and get measurments on the wheels

 

so nobody? Anyone know where I could find online specs of these?

 

get a $10 set of calipers or even eyeball it with a ruler to get a guestimate of the compressor and exhaust wheels. The s300 looks big to use as a top turbo. Your hy over the s400 should work though. Might want to do an external wastegate along with the internal.

 

I cant remember what the s400 is but I know if its a normal s300 is a 57/65/14.
As long as you have a good amount of fueling, the s300/s400 would prob be a real good combo.
Prepair for head studs, fully built trans etc etc though. That couple could make alot of power. Id guess 700 hp and 60 lbs boost? Maybe more if all worked right.

 

Is it a problem that the exhaust housing from the small turbo isn't split you think?

I remember when I bought them that I did do some research and that they came out just fine, but I can't find the correct specs online anymore. I listed them both on ebay, if they sell ok I would go for a complete set. I don't want make more then 600, I want low EGT all the time

 

What do you mean split? You mean the wall shown in this pic?

Yes like that one

 

I read once why its split like that, but cant seem to remember why.

I think I remember reading that if you cut that wall out, it does something for quicker spool/lower egt slightly. Or something like that.

Hopefully someone else will chime in. But if it came like that new.. Id say its fine.
