Big Rig Turbo

I just got up here to my cousins place to work for the summer. The place I work for has a bunch of big trucks and with big trucks comes big turbos My cousins moved to a new place last year and with the property came a few other goodies, one such goody is a massive turbo that was most likely came off one of the old owners trucks. It is probably more than twice the size of the stock turbo on our trucks. I don't have any pictures or measurements of it at the moment (I'll try to get some tomorrow) What I am wondering is how hard it would be to get the oil lines hooked up, get a proper adapting flange and just generally get it to work... I am looking at getting a stage 4 injectors during the summer and would like for this to work as it would save me quite a bit of money on a new turbo.

i doubt it would fit with out HEAVY modification, and I doubt it would be worth all that extra time and money. sell the turbo on ebay and use the money to get a dominator turbo from beansdieselperformance.com direct bolt on and a great upgrade from what i hear. thats what i will be going with. and also stage 4 injectors? never heard of them. what is the cc rating on them. dan

I would think the lag would be NUTS on a turbo that big..... Probably still wouldn't flow enough air to get it fully spooled up and make it efficient enough to work... but lets see pics before i judge more...

Stage 4's ?????? Hybrids maybe are what your talking about? maybe B codes....

Robb I would wait till I got new injectors to throw it on so it wouldn't be THAT bad of lag I would think As for the injectors they aren't technically stage 4's I have been eyeing up the 490/xxx injectors from Swamps and will be ordering them as soon as money permits immastrokinnow as you can probably guess they are 490cc injectors... which would be nucking futs!!!

Jdap, Humm, I don't know man, even with those injectors I don't know if you'd be flowing enough, and I'd think there would still be some serious lag. I'm not standing there looking at the turbo, so I can really say **** but is it's HUGE then it may be a waste of time. A big turbo is great but if you can't get it spooled, or if it takes forever to spool whats the point? Again we'd have to see what ya got there. I'll reserve further judgment till photos.

I would not recommend those injectors until you have serious modifications to your engine, fuel system and trans. Otherwise you'd be wasting your money. You probably wont be able to spool the turbo off a big truck, they are made to work on an engine that could be 12l and spool at 1700-1800 rpms. In other words, it wouldnt spool on a 7.3l until probably over 3000 rpms. If you skip to a huge injector or huge turbo w/o the proper mods your truck WILL NOT be very streetable. 490cc injectors with the right supporting mods flow much more fuel than is needed to bend stock forged rods. I guess what im saying is your nucking futs for even thinking about getting 490cc injectors with your mods.

Thanks for the concern Luke... I was just saying that with those injectors I didn't think that it would be much of a problem to get it spooled up. I have plans for adding a lot more to the truck too such as intercooler, head studs, fire rings, rods, ported heads, pistons, big oil, FASS fuel, BTS tranny and the list goes on. I was thinking that after that it would be much more streetable and probably downright fun to drive!

I hope I got deep pockets too! I've been thinking about the money situation and I am hoping to have ~500hp at the end of the summer.

You'll need rpms along with fuel to spool the turbo. If the turbo doesnt spool until 3000 rpms, what good is it on the street?

For 500 all you need is modded h2e turbo, headstuds, valve springs, 238cc hybrid injectors, trans, fuel system, intercooler, custom tuning and intake/ exhaust. The setup mentioned above actually did well above 500rwhp in my truck and ended up bending forged rods in the process. It towed great and was a blast to drive.

Luke, don't some of the PSD pullers use like compressor wheels in the 80s? I remember reading something somewhere that guys were using that size.

However, those trucks are probably not daily drivers.

Good to know!!! I was thinking it would take a bit more to get to that level... now you have me itching to go to work so I can make the money for this ASAP. Did you have it on the dyno with that setup? If you did what were the numbers... I don't expect to be the exact same as you but a benchmark number would nice to have.

Get some info off the turbo first. there should be a tag on it. brand, model and exhaust housing size will be the biggest factors. The H2E is nearly twice the size of a stocker so you never know until you have specifics.
