So I Have A 98 12v Auto Dualy Ex Cab I Am Looking To Get About 500 Rwh And I Am Trying To Find The Right Turbo Injector Combo To Start This Off Whith And Should I Get A New Exsaust Manafold Or Not I Have Checked In To Silverbullets Phatshafts And Supper Bees Where Else Should I Be Looking Also What Is Realy A Safe Psi To Go On Stock Head Bolts And Gasket

 

High Tech Turbos are very popular as well. I don't know much about the fueling on the 12 valves but you could get a set of 370 Marine Injectors, fuel plate, governor spring and a turbo. But before you throw major power at something, make sure your tranny is up to the job.

 

Well I Failed To Mention That I Have A 10 Plate Full Forward It Tows Daly And Sometimes 20000 Pluse Pounds

 

Hopefully someone else will chime in, my knowledge of the 12 valves is slim to none

 

Well Thanks Anyways Come On Guys I Know Their Is A Ton Of Knolege Her Give Me Youre Opinion

 

35-45lbs on stock head gasket/bolts.
I've personally pushed higher numbers and saw people push higher numbers, but then again I saw people pop head gaskets @ #37.

I am personally looking into the Super Phat Shaft 62 or HTT SS.

You'll need a set of good injectors to fuel the turbo tho so I would look for a good set of injectors. Marine 370s are probably the cheapest route but not most efficact from what I've been reading. I've read somhign about DDP4 or somthing like that?

What transmission do you have?
Star-wheel cranked up?

Edit;
Just read you have a automatic transmission.
I assume stock torque converter, if I where you I would bank some $$ for a torque converter if you're gonna start fueling it and pushing more boost.. espically if you're going to be hauling that amount of weight you'll slip the stock torque in lockup like nothing!

 

i allready toasted the tranny and got an art carr seem to be strong but i have only 250 miles on it i have a ton of smoke so i dident want to screw whith the star wheel yet and the 10 plate is slid all the whay forward but nowone will tell me the differnt charteristics of the differnt turbos top end bottom end driveability or psi and what kind of injectors i was wanting to get some whith more power aslo keeping fule milage in mind

 

well, when I had my 12v I threw a set of 370's in and was IMPRESSED at the fuel these things would flow. However, it came with a price. It had a horrible stutter at around 1200 rpms, very annoying. For the money, you can't beat the 370's, however a set of ddp 3's would be worth it, very smooth power.

 

How Did The 370s Do On Milage As Long As I Dont Get Worse I Dont Care I Sit At 10 To 13 Mpg But I Also Have A 2000 Pound Welder And About 1000 Pounds Of Crap In The Bed At All Times

 

I got about a 2-3 mpg gain when I could keep out of the skinny pedal

 

i have that problem as it is who is a good company to go to for them

 

It depends, you can get you're run of the mill 370 Bosch injector pretty much from any where,prices from 300-400 dollars. Now if you want insane power and smooth fuel, the sell hot rod 370's from Performance Diesel. They hone the injector out and made internal modifactions so you don't get that "stutter" I was talking about, however it comes with a price, 800 dollars. Check ebay for good prices on the stock 370 injector(just use a legit company, not an individual seller).
