Competition 4lhr as lower turbo on twins?

[Smokin59 4x4]

I have a Schwitzer 4lhr-753 turbo and was planning to use this as a lower turbo with a hx40 upper, but just want to be sure it'll work fine before I waste time rebuilding it. I'd also like to find out the turbine sizes but haven't been able to so far. Just use the truck for street/occasional strip. I'd like to get low-mid 13's someday with it but nothign too radical. Also is the exhaust flanges the same as an HT3b in case I decide to go with that later? Just don't want to do this twice. Thanks in advance.

I've searched on this, and found some comments that helped, but still looking for the housing sizes? Anyone?

Did you try www.diesel-central.com?



A few of those guys have more experience with "Non- TDR acceptable turbos, fuel, etc. " for lack of a better term.

Absolutely good guys over there on diesel central, good point Sled Puller. Ian, what did that turbo come from? I might be able to get a Schwitzer for free off a 2000 E7 Mack daycab 350hp, it doesn't look that big on the truck lol! Don't know what it is though, just its a Schwitzer.

4LHR is about equivalent to the HT3B in size and specs.

I wouldnt hesitate to use one in a twins set-up.

Not sure what it came off of for sure, I was told a 14L cummins but i've been told alot about alot and have learned not to take too much to heart. I knew it was a 4lhr and i've heard they've been used on twin setups, it was cheap, so if it wasn't going to work I would've made a cool end table or something lol. Is it more like the 26cm housings on the ht3b or the bigger housings? I'm looking more for top end power of course, with a hx40 16cm upper Im not expecting super super fast spoolup but a little bit would be nice.

The ones I have encountered usually have large turbine housings.
