Truck Turbos
It looks like some truck turbos might be a very cost effective solution to a single turbo upgrade. I am going to give it a shot but have found a lack of information on which turbos are well suited to a street ported 13b-rew.
Ive found that the Holset HX35 (from dodge) has a turbine A/R of .84 but can't find info on which models have this turbo or info on the compressor side
I've read on here that the powerstrokes have
.7 comp and 1.0 A/R P-trim turbines
don't know the years
Detroit diesel
TV7301 Garret. Compressor .78 , turbine 1.08. the compressor wheel is 3.00minor and 4.20 major. the turbine wheel is 3.30 minor and 3.80 major.
Thats all I have... I need some years and models so I know which one to grab b/c none of these people will know their turbo size. After this is over with I am going to start a website that documents the sizes of all stock turbos I can find info on. It should make a lot of lives easier...as it is there is NO info on the net.

Thats a good idea to document your research, see if i had id be able to help you more. haha. Anyway i know the TV7301 is still in production and its used on 2 stroke diesels. Its fairly cheap(750) and its as big as a T88 or so. Your only problem is you may need some extra poweradder to get it going.

The HX35W looks like it's all wrong for a 13B.
No, really!
If I'm looking at the compressor map right, it would be in surge at any RPM below about 3500ish. And it has a smallish hotside too.
For reference - on a 2.3 Ford, it builds next to no boost below 3000ish. The turbo being in the surge part of the map. By 4000, it will produce up to 29-30psi with no wastegate, *that fast*.

The holset HX-35 is the same KKK turbo used by SR Motorsports. Although there are different models of the HX35 so I would like to figure out whichs ones are which so I can get the right one and do my turbo kit for 1500 instead of 5,000$

The HX35 non-wastegate model has a much larger hotside (since it was used as a free-floating turbo) that might be good to use. You'd need an external wastegate, obviously...
It was used on '91-92ish Dodge Cumminses.

I drove around all day today looking for information on these turbos and came up with the most redneck, retarded answers I have ever heard in my life. I did find one place with a ton of turbos but "who the hell'd want an engine without no turbo?" ... oh gee maybe someone with a blown engine? DUR

You can buy the turbos new off the Internet for like 400-600$, most of these truck turbos are real cheap, its just finding the right model # since nowhere lists anything about sizine or anything.

Check the JY Turbo guys... a lot of them have these things figured out. Of course, all of it is for boingers, so you need to do some figuring, comparing what we know already of what works on boingers (for "known" turbos) and how they react to rotary exhaust characteristics.
It just seems to me that the HX35W *might* be OK on the compressor side, running into surge problems on the low end, but the turbine side is just too small. The HX35 as used on the non-wastegated early 90's Cummins Dodges had a much larger hotside to prevent overboost (free-floating setup) so this might actually be what we want for a rotary.
Two tidbits I've found on the HX35W's...
1.
And then this guy who put a HX35W on a Ford 2.3, with the wastegate disabled...
Looking at the compressor map, the reason the pressure flew up at 3800ish is because the turbo was in surge below that point. So the hotside was causing it to spool too fast on a piston engined 2.3 ?? Like I said, looks like the wastegated turbine housing is too small for a rotary

>HX30w?
Go with the HX30 on the 2.3. Worked with both a 30 and a 35 on a 2.6L
Conquest. With the 30, it made boost from about 1800rpm and up, 16psi
(wastegate setting) was in by 3K. The 35 made 8 psi at about 3000, and made
16 at 4500. Overall, the HX30 was the better street turbo, and only gave up
a little on the strip to the 35. Now, if the boost were cranked up, then
the HX35 would have been the way to fly.
The car ran low 12s with the HX30, and high 11s with the HX35.
The HX30 will handle the 375hp, no problem.

After a short warm up time, I did a quick 200 foot run to see if I would be able to get any boost. The road in front of my house was too short to do anything but stab for 3 seconds and let out. But I heard the turbo make that wonderful sound over a fuggin loud *** exhaust. I saw roughly 3 pounds of boost at about 2500 rpm.
(....)
I started out from about a 1 to 2 mile per hour roll. I reved the gas and slid the clutch till it locked up at 2500 rpm. By that time I was on the gas hard. I stayed in it till around 3800 rpm when I saw the needle rocket up past 25 pounds of boost. By the time I reacted to let off the gas, the boost gauge showed ~28-29 psi of boost at ~4000 rpms!!!

Hi, some info I have on the 5.9 Cummins Turbo:
From 89 to 93 they have the "H1C" turbo with 18cm to 21cm
From 1994 to 1999 they have the "HX35W" 12cm and 14cm hsg
From 2000 to present "HY35W" 12cm hsg
All these turbos have a T3 footprint. 16cm non wastegated housing are available from performance diesel shop. I'm currently building a kit with the HX35 /12cm for a guy who makes road race and want a fast spool up turbo. If I can finish and test it before the snow begins to fall I will let you know how it goes.
hope it can help!
