a few performance questions

[blackcloudpsd03]

Can you run a t4 up pipe kit with the mechanical pump still in the valley ? I'm deciding if I want to put a s366 on or a fmw 467.7 at no point do I ever plan on having large injectors. Possible stg2's no more. I want to keep it turn key and go no headaches. And reliable. ( I learned with my dodge and 6.0 a hot rod truck only appeals to about the 2% of people looking for a truck)

What is the benefit of running a 17° pump in a obs? All I would have to do is switch over fittings from pump to pump? Gaskets are the same? ( is the 17° come out of a 01+ ??)

Truck in sig, or different, I'm assuming?
A 17 gives you more available oil volume. It should bolt right in, with the 94_97 gasket, and if in decent shape, will be plenty of oil for 160/0_30_100% nozzles.
A stock or 38r turbo with clean these up easily, and there's a bunch available, and if you look around, you can find all the parts pretty cheaply.
A t4 has way more available options, though, and if you want to try different setups, that's the way to go.
"Bruce" has a for sale thread in the classifieds, with a slightly diferent setup, maybe something to interest you. Sorry, I don't know how to provide a link.

No its for a 97 350. The truck in my Sig is my 6.0. With a 38r Dont I have to run the SD up pipes? They sound pretty nice. Dont you have to beat the fire wall with a 38r? To clear the WG arm? But the 366 is free. Lol

I will go check it out. Still doesn't answer if you can run a t4 turbo kit wityva factory FP

One more question I was poking around on the interwebz looking for injectors what's the difference from stg1 and stg2? A few sites I was on showed both 160cc injectors but with different prices.??? I figured 2's would be a 175-180cc I know 238/200's are 3's . I looked at rosewood. Rcd.. full force .. Swamps. What brands are you guys having good luck with?

38R needs the 99.5-03 turbo setup including uppipes, pedestal, compressor manifold adaptor and turbo inlet adaptor. Some have had to clearance the firewall a bit.

Don't know why you would run a bigger turbo and not install e-fuel. Stock OBS pump is only good for a touch over 400hp (and I mean just over 400, did 408 with mine and picked up horsepower just switching to efuel). You could always reinstall your old stuff when you want to sell your truck. Its not hard to install e-fuel.

To me an electric pump of a sd truck is way more reliable than the mechanical pump, plus if it does crap out its way easier to change on the side of the road. The electric pump will also be able to maintain adequate fuel pressure to keep the injectors happy.

 

[blackcloudpsd03]

Just wire it ko pwr? With a fuseable link? And Keep the factory fuel filter? Or ditch it also. ? I knew the pedistal had to be replaced as well as the up pipes. Does the WG arm hit the fire wall? Or the coupler on the up pipes? I know there a tight fit on the sd's

I know I say it now. I do t want this or that but it happens its a horrible hobby. I said it about my 6.0 and that didn't work too well. Is the d66 the same thing as a 38r?

strictly diesel sells all parts or a whole kit,

 

[psduser1]

If you have a 366 available, buy the t4 kit. Jake@Irate diesel has them, as well as several other vendors. Pretty sure most of them have obs setups engineered, bolt in and run.
X2 on going to e fuel, also.
As far as injectors, Tim at pis, Ryan at fullforce, Dave at swamps, and nate at unlimited all sell reputable injectors. Stage one is usually about 160 cc injector with a stock nozzle, stage 2 is usually same size with a larger capacity nozzle. Most folks here will ask for and reference injectors by size, i.e.160/30%, not "stage".
Personally, I see zero advantage to any nozzle size less than 80% over stock, if you are running any sort of custom programming.

 

[blackcloudpsd03]

^^^^ thank you that answered my question about inj size. Im just reading off the website I see it from. how big can you go on the oil side of the injector before you start dropping ICP press?

 

[psduser1]

I think most stock frame replacement pumps recommend 238 cc or smaller injectors, and medium-sized oil is sketchy. Big oil is reasonably nailed down.
Having said that, nozzle size plays a big reason in tuning, enough so that if you are considering how "big" of an injector you can run, I'd spend some time talking to your tuner of choice. There are some variables.

 

[blackcloudpsd03]

Besides dp php. Tw. How else is reputable? I know gearheads is tuning 7.3's I run them on my 6.0 and it blows idp out of the water.. With a 366 and 190/100's it wasn't too laggy hardly smoked. I know in the 6.0 world nozzle size has a big play into holding ICP press. Ie: 205/75 will hold but a 205/150 wont or a 225/100 holds

 

[blackcloudpsd03]

So would you need to run a 200-238cc to run a gt4294? I been reading around a lot of people like them. Just no one mentioned what size inj they are running

 

[bruce]

4294 is 70.3mm inducer, 200/80 would probably be the smallest i'd go, all the way up to 300/200's

 

[blackcloudpsd03]

How about tuners? If I did 200's and a gt42? 425 HP ish?

 

[bruce]

if you're only gonna run small hybrids just get an s366, no need for a gt42. Dyno proven, swamps, php, power-struck, tony wildman, gearhead, diesel innovations and dp all off tunning. 200/80's could make 500

 

[blackcloudpsd03]

Have any of you guys ran the fmw series turbos? The 467.7 ? For 500hp do you need studs? Bottom end work?..
