The stage 1's and 2's have the same cc, but with a larger nozzle it will empty quicker and the stage 2's are able to make about 75/100 more no than the stage 1's.

I was looking at this setup before I posted on here for your opinions first on upgrades.

425RWHP for that price seems pretty decent to me.

Peter, what is the "light modification" on your 02?

smokinstroker92 · Nov 29, 2013

If it were my truck I would run ff 250/100s, fuel system, and a 38r. With a strong hpop that should be a clean reliable 500 all day. I have a truck with 250/100s an stock turbo that's about 450 according to track times. This is all with gearhead tuning

Is there a big difference between the 38r and 366 as far as performance? I know the t4 allows for more options but that's all I really know.

As far as my trans I pretty much baby my truck most of the time except the every now and then little bit of fun. And i don't race or do pulls.

Would it be safeer going with a package like I listed before?

425 horse can be done for a lot cheaper than that package deal. you have another couple of hours to save 15% on injectors from performance injection systems. for you i don't think a t4 with s366 is worth it.

smitty4605 · Nov 29, 2013

I don't have the money yet so I will be paying full price unfortunately.

So is the 38r good for towing? (Sorry for asking all these questions)

Right now my current setup doesn't seem to like towing my single car trailer with my jeep on tons I can only imagine two jeeps and 27' gooseneck. Then again it could be bad now because of my leaky up-pipes.

38r is a great turbo. Its absolutely a great turbo for towing. Especially with a tuner and some slightly larger injectors.

I personally dont think an s366 is as durable or as wise of an investment as a 38r. They're cheap, thats about it. But there's something to be said for that too.

Idk. Ive never regretted purchasing my 38r. Now with the billet wheel that has totally obliterated that frikkin siren noise, its even better.

A stock truck with a tuner should yank that jeep down the road with no trouble.

Yep!! My brother tows a gooseneck that grosses 12k-16k weekly with a billet wheeled stock turbo and a tow tune from nltd and loves it...

Im very happy with how my dually performs and I would suggest how it's setup to anybody who wants a mild upgrade to tow with...

Ran that setup for a few years. Reliable with good power and manners. Only a nozzle swap away from 475-500hp.

smitty4605 · Nov 30, 2013

So the 38r is more reliable then 366? I just read everywhere to go with the t4 mount and be done with it. But since I don't plan on racing or pulling (well maybe one or two) the 38r would be my better choice? Does the 38r get a lot of surge with out the billet wheel?

Phhht. 38r is a throw away. Go 366

Smoked a bit
Turbo lit
That was it

You didnt like yours? Or are you thinking of your pmr's and got confused?

jaybuller · Nov 30, 2013

In my opinion the 38r is a great turbo, as long as you keep clean oil flowing to it and don't over fuel it - and keep it under the recommended boost levels! Who cares if it's a throw away turbo? Treat it right and it's gonna last long a the truck itself! For those that are gonna beat the piss out if it with 250 sticks should stay away from it but those of us who have smaller injectors and like to have a daily driver that spools faster than stock it's perfect and lasts! I would recommend the 38r for anyone from stock injectors up to small hybrids that's tuned to 425hp or lower

TyCorr · Nov 30, 2013

It'll cost you a lot more to run an s366. For building a towrig, that will be 400ish hp 38r wont be breaking a sweat.

In fact Ive done that before. I ran 175/80s and a stock 38r. With superiorly clean tuning(you couldnt actually make the truck smoke) it made 405hp. After adding 100% nozzles it gained about 15-20 hp and got hotter. Tweaked the tuning and it was still not as "right" as the 80% nozzle. I ditched the injectors to run a hybrid because it seemed they just werent quite enough. I wish I would have tried them out with my irate fuel system and srp1.1 because the truck runs so damn nice now even with stock injectors, im wondering of they wouldnt have worked out better.

Oh well.

If you look at Jake(lincolnlocker) signature theres a 2000 dually in there, that is over 470hp with 170/100 injectors. He has all the mods listed. That setup, according to him, tows waaay better than his brand new 6.7 powered f350 and getz better towing mileage.

Truck has a 6" lift on 37's. Built trans with billet converter, DP Tuner with 4 tunes. Ported compressor housing, full exhaust. AMP steps, traction bars, nice stereo system. And of course, ALRADCO aluminum radiator

Will be throing our intercooler in as soon as we get to it as well.

Thinking about doing HPOP, injectors, and gears. Also going to put air bags on it in the next week or two.

Touche'

Imo, stuff happens. You blow the 38r and youre out another 1300$ because you can't rebuild them... That right there could buy your 366 and if it blows it can still be fixed

yuuuuppp! Dead on right there..... but those of you that dont know, that is by far not normal! Dont take that hp number and think that you will make close to it.... it should be a 400-430hp truck and thats it.. ET puts it at 450hp and one mph run puts it at 470hp... still dont know of anyone with the same mods making close to that with time slips to prove it.. its a freak and nobody knows why or how it runs the way it does..

But it is a bad ass tow rig. I just coukdnt keep my foot out of it cuz it is way to fun to drive! Its my puller/competition truck now with more upgrades in the future.. thats the reason I bought the 6.7 and it could use a mild tune for sure..

Might not want/need gears after you do a hpop and inj upgrade.

smitty4605 · Nov 30, 2013

Can the 366 be ran with smaller injectors to keep everything somewhat happy? I just like the idea of t4 kit because of the new intercooler pipes and boots along with the new up-pipes. But if the Jake (lincolnlocker) had good luck with his setup then maybe that is the best way to go.

Im listening to your guys opinions and trying to soak in everything because you know a heck of a lot more then me.
