Getting ready to do the mods on the cummins. I want to slide the pump plate, It has that one weird screw, Is it a beak off screw or what? How do i get it off? And can i actually slide that plate or should i get a modified plate? Its a 1996. Does anyone know if the bigger turbo housing does anybetter? What are the best mods for bringing this cummins up some?

I have my stock plate & the pump is turned up to fuel to 3800 rpm . No parts were replaced. The rpms were set to cummins maximum spec. The bigger housing is a big improvement over stock. I started moving the plate around so long ago (8 years ago) I vaguely remember useing a cold chisel to make a screw driver slot to remove. Then replace with new hardware. As far as the internals of the pump, I cant take you there, but a cummins shop manual could. You will also want to adjust the star wheel to start fueling sooner. Its been a long time since I had the pump / turbo housing work done, ( but I havent been able to wipe the smile off my face since).Im sure someone else could be of more help. doug PS injectors will complete the package.

Thanks for that info, Ya I was wondering what they meant by the star wheel. I guess it has something to do with throttle response? I'll have to find out where its located. So i guess i'l need a stonger govenor spring also. I think this cummins is maxed at 2700rpms, So it can go up to 3800? Thats more than my 6.2 chevy, I dont think i really wanna take it over 3100. Ok so the larger turbo housing is a plus. Can you hear the turbo spool now ? I want one of those long lasting smiles too !

The star wheel adjusts the preboost fuel (basically helps spool turbo). Its on the afc housing with a big I believe allen type screw. I took my break off screw on my afc housing off with a chisel also. If you want good mods either the number 10 plate is good or you can grind your stock one down if you dont want to spend any money. You can move the plate forward but watch you egts and dont forget to move the afc arm forward too. You do this by an allen bolt on the back of the housing. 3k gov. springs will really wake up the truck. I dont see you needing a larger exhaust housing unless you start to throw some more fuel at the truck.
If you want to get crazy then you can get some injectors and then maybe you will want a bigger exhaust housing or you can upgrade your stock turbo really cheap at www.htturbo.com to a hx35/40 hybrid. Oh yeah if start doing this be nice to your transmission:D

Right on! I think this engine is going to be the most fun i ever had messing with, Thanks for all the info, Cant wait to start with this project, I dont even have meters yet, So i wanna do most of it all at once.

What transmission do you have?

Its a 1996 2500 , 5 speed stock as stock can be.

Don't bang gears !! The 5 speed will bite back. Cost me plenty when my imput shaft let go.

I wouldnt get the bigger turbo housing unless you are making your turbo into a hybrid. Mine didnt really help anything, and it spools slower. I think i am going to put my 12cm(stock) housing back on soon with a modified wastegate. Go to www.tstproducts.com (http://www.tstproducts.com) to the technical arcticles. You will find a LOT of help,and visual information there. Good luck.

Copy the Not banging gears.. You can just tell that these gears are made to shift one way. They go in and come out one way. Any problems with the 5th gear nut yet? I wonder most about the KDP. Now thats scary. Can you notice a big change with the 246hp and 635tq ? That to me is perfect ! I think mainly i want to get the gauges in and the fuel plate and big head waste gate and get the star wheel adjusted for quicker spool and response, Then i'll be on my way. Who knows i may leave it a lone after that for a wile. Hey Merry Christmas

Definatley much better than stock. Pulls pretty darn good too:D I have the smallest pump; so you should easily be able to reach 246/635. I should be more around 270hp/700tq now. I definatley reccomend the Governor spring kit a lot for driveability. That and a fuel plate will really wake one up. If your 96 is out of a 5spd truck, then you have the big factory 215hp rated pump and if you only add a fuel plate, it should get you around 300hp/750tq. So i am sure you will be happy with a fuel plate. I also still get 22mpg highway; so you cant beat that. Mery Christmas to you too.

Ok i got the plate moved all the way forward and adjusted my star wheel and took out the turbo silencer, The adjustment on the afc housing you mentioned does what now ? I see it, it has that rubber cap on it, Do i screw it in ? And how far ? Thanks a Mil !

Another quicky ! In your opinion, If i bought new higher performance injectors instead of a fuel plate, What would that do ? About the same ? Or higher EGT's. "Can you beleive its 2006" I never though i would live to see a 2006 Dodge Mega Ram, Wow, Are we blessed or what ?

Ok i re-read my post, And what i meant was i know this isnt a racing transmision. Ok Another question: My turbo-lag\spool time is slow. I guess they dont spool till they have 20 psi from the waste-gate eh? Can and will it hurt it to adjust the gate ? I was trying to find on the web more info for that Bills Turbo-Master gate actuator, Sounded like the thing to have but the site i found only supply's for GM . Maybe they canned Dodge, I dont know. I guess i could e=mail them. But it would be nice to have that Turbo spool alot sooner, The star wheel didnt seem to effect the lag. Any one have any info fo me?

Hmmm. Well; the wastegate has no effect on spoolup UNLESS it is sticking open. It only affects maximum boost reading, and as long as you dont go to far with the fuel; then you can block it off all together and not hurt anything. 32psi is about as far as you can go with a stock turbo before it starts pushing hot air. On the spoolup; i really dont know. Does the truck have more power since you adjusted the plate, etc? My starwheel is as loose as it gets. Its possible your governor lever arm is riding under the plate and hurting your low end, and raising EGT's,and then finally getting onto the plate, and making some power. Only way to know is to check. If it has a stock turbo; it should spool pretty quick with even a little bit of work to the pump. Good luck

If your turbo is spooling to slow, try playing with the afc wheel. Rotate it towards the engine, this will add more fuel to help the turbo spool faster. Grind your stock plate down, this is free if you need more info I can probably find a pic somewhere. As far as turbo adjustment, you buy an adjustable boost elbow from tst or you can make your own fairly cheap from a hardware store. If you have a good plate, big injectors , gov.springs, boost elbow a free flowing intake and exhaust you should be around 400hp. If everything is tuned good. As far as you clutch holding I am not sure on that:D

Ok Ya I took the truck for a good ride today and yes there is more bottom end power and the turbo does work a little better. If i am at say 1000 rpms 4th gear and mash on it. It take aprox 4 seconds to spool, But 4th and 15-1600 rpms -Spools fast. I am sure its all workin as good as it gets with stock stuff, The star wheel gave me some accelerator smoke and bottom end power up. So ok I got the templates for grinding, But cant do it yet cause its slow at work and wife say no money spending till the work pics up. I mean i gotta get the Pyro in first or no deal , U no wut I meen ! Boy i really appreciate the help, I spent some time last night watching some Dodge sled pulls and i gotta say Theres no stopping me now, Its got my motor dieseling ! Thanks Guys !

Sounds like it is spooling up fine. That is just the characteristics of a turbo. Have fun with it;)

Yes, the killer dowel pin bit me . Yes, the 5th gear nut bit me ( under warranty though ) also lost a 5TH gear syncro(out of warranty) Head gasket bit me. Several track bars. Two starters. And to top it off cracked block syndrome( small crack in right side of block from freeze out plug forward about 4.5 inches. Heart breaking, yes but I still love my 12 valve. doug

What the heck did you do to it?:eek:

Eric

higher EGT's.

if it starts gettin hot pyro whys then advance the timing on the pump to about 16-18* that will cool her down a bit

What the heck did you do to it?:eek:

Eric I dont understand the question ?

I dont understand the question ?

Was it a #53 Block? They had documented issues with those

I dont understand the question ?

Just saying that was a lot of stuff to go wrong. lol Most the time the blocks dont crack on the trucks before the 53 blocks time.

Got Juice: He couldnt have had a 53 in a 96. They hadnt made them yet

Eric

I dont understand the question ?

i think what he meant was ...do you run the dog sh!t out of your truck... because of all the things that seem to have gone wrong with it

Six .two Turbo Your next step is the Non waistgated housing 16 cm housing. My truck runs 42 pounds of boost in 4th & 5th gears. I beleive my Timing is set to stock So that would be my next step. The only time I had to back out of it (because of EGTs) ,was when towing.

I would say that i never really beat on it. I sure it would break on the spot if I did. These days I mostly roll the power on gently. But there is enough power to break the tires loose in 4th gear (open rear). When I went to cummins to ask for help on the cracked block they were not surprised, & had seen a few come through there shop. I wasn't about to dump any more money into it , so made several attempts to repair the block. The latest fix is a product is called Zip Patch by Devcon( so far so good) but I wouldn't be surprised if it started leaking again. There is about 215,000 on the truck now. So I will just keep doctoring it up until something major fails.
But it runs flawlessly. I once ran dead even with a Mustang 5.0 from 80 mph to my red line 3800 rpm on 285 tires (do the math) . He didn't start to pull me till I hit 3800. Boy was he surprised.
