My car ate a valve and if I decide not to rebuild it I would have my turbo from it which I could possibly put on my truck. It's a AGP built dual ball bearing "Delta 65" which is just a 65lb compressor wheel of their own design in a .70a/r 4" inlet, 2" outlet compressor housing. It's a T3 .63a/r exhaust housing with a P-trim wheel. I'd have to run an external gate, but I've got a couple of those laying around too. The compressor is still good to 30+psi but I don't have a map for it.

Would it be good for a single charger? Would it be better than the HX?

If I got a large turbine housing for it, would it work with my HX for a twin setup? What size would I have to get?

 

my buddy has a gt35 turbo on his 02 24valve dodge.

its the same thin. .7ar compressor 2 inch outlet,4 inch inlet t3 .63a/r
and it runs ok, kinda hott egts with .63 compressor housing. id definatly want something bigger. but .7 compressor is kinda small too. youd be better off with your mods to just get an hx40 or something

 

Dan your *** is ALWAYS tryign to push an hx40. Until your truck can beat mine stfu hehe

 

.70a/r is just the compressor housing. It's the same inlet and outlet as the hx35, but I see that I made a mistake where I put it as 2" instead of 2.5" outlet.

I'm suprised that it's hot on egt's unless it's just the .63a/r exhaust housing choking it some. He's probably got the t350 exhaust wheel, which is normal for those turbos. It doesn't flow as much as the p-trim.

This is a 650hp turbo on a gas engine so it suprises me it wouldn't flow enough, but I don't know too much about matching turbos to diesels.

 

no the .63 a/r housing is way small.
maby if your cruising around in a stock truck it would be do able, but as soon as you push some fuel it will sky rocket drive pressure and throw the egts threw the roof. even prolly with an external wastegate.

@85 305 an hx40 is a great cheap dependable ugrade over stock. almost anyone pushes the 40 as a start. a noobie like you wouldnt know that tho

 

Dude I'm all for an hx40. You know that. Oh wait, your a klein. You dont know that

 

What would be a good match then for a housing? I don't want any more lag than I have now. With the new tighter converter it's even almost too much for me now waiting on it to spool.

Do twins normally spool later than the stocker when you use the stocker?

Basically I like fast spooling stuff for the street and that's what this truck is for me. If it was a 4wd or short bed or at least regular cab then I might think of drag racing but that's not the case for me.

 

The problem with "fast" spooling turbos on a diesel is to get that you need to give on the other end,which means higher EGT's due to a tighter exhaust housing and no top end charge due to the smaller compressor wheel.

On a diesel pickup you will either excel in one or the other,spool up or top end charge.You will not find a turbo that does both as many of us have sought that for years and have yet to find it.

The turbo your telling us about is way to small to be efficent on anything more than a stock truck,even it its claimed to be a 650hp gasser charger.So you can have a better idea when you compare it to a gasser charger,look up the specs on a S300 or S400 framed charger when used on a gasser and see what it relates to for HP there and you will see what I mean.

 

I guess what I'm not understanding is how you can say this charger would be too restrictive even if I go with a .82a/r housing maybe. It flows more than a hx35 on both the intake and exhaust with the housings it has now. I've seen the maps for hx35's and had experience running them and hx30/40 hybrids along with the Delta 65. The hx35 is a quicker spool with a 12 housing and way quicker with a 9cm housing than the Delta 65. They don't make as much up as the delta 65 either, but it's not a huge difference. I also looked into the smaller s300 series extended tips when I was looking for a turbo for the car. They're in the same ballpark as the 65, but the s400 stuff is quite a bit bigger.

Just thinking about it, I woulndt think this would be a bad street turbo, but I understand it would choke some up top. What I really don't understand is how twins are set up and how to size them for different goals. I've seen dynos of say 500whp single turbo diesels versus 500whp twins and the graphs are night and day. The single spools late and peaks at high rpm while the twins have a table top curve with a very broad power range. How do you set up a small quick spooling turbo with a big high flowing turbo for both quick spool and bigger flow up top?

What would happen if I put a big housing on this delta and paired it with my hx35 how would they spool and flow?

 

im running twins, super 40 over an ht3b, if you want any help,tips, or pics of building a set. pm me ill be glad to help and lead you in the right direction
