Engine/Transmission (1998.5 - 2002) PROPER ORDER FOR UPGRADING YOUR ISB

[Ted Jannetty]

Hello to all,

I had posted a similar thread months ago and thought I would post it again since there are so many new members, and this is a frequently asked question.



1) Guages, boost Pyrometer, optional transmission temp, or fuel pressure.

2) K&N air filter in the stock air box or a JRE Cold air Kit with Heat sheild.

3) 4" exhaust turbo to tail pipe, preferably mandrel bent aluminized.

4) Then some sort of fuel enhancements, i. e. Van AAken CPC or larger injectors, but not both at the same time until upgrades to the torque converter and valve body on Auto's, or a clutch on a manual

5) High quality low stall converter, preferably 1600 rpm, and a valve body modifications to recalibrate to handle the extra power.

I prefer the Star performance clutch on the manuals.

6) Depending on what you choose on #4 finish the job with injectors or Box.

7) 1/2 inch fuel system to feed that hungry powerhouse, and keep that injection pump cool and lubricated.

8) 7psi 100 gal. hr. pusher pump at tank.

9) 15 psi 100 gal. hr. lift pump on engine.

10) US Gear 20% Overdrive auxillary transmission so you can use all that new found power.

How's 1800 rpms at 75 mph sound?

11) A BD turbo mount exhaust brake to slow her down.



This information is based on my 19 years expierence modifying vehicles to fit the needs of individuals, buying parts that don't fit and making them work better than they where designed too, finding ways to put 850 hp to the ground with a 10 inch tire, soon to be 1100 hp 360 cubic inch small block chevy.

Leaving the starting line with the front wheels three feet in the air for the first 70 feet is a rush like you wouldn't beleive.



I love what I do! only second to my wife and kids.



I hope this helps

I edited this message to update, not much has changed!

Ted, somewhere in there, I'd reccommend going to a 16cm2 exhaust housing on your turbo. Our experience with the one we did recently, is that it's very responsive.

It also came with a higher pressure wastegate actuator.

Hello Powerwagon,
If yours has a wastegate actuator on it, it's probably a 14cm2 from a 230 hp motorhome.
I have been down this road many times before and proved that for most, it is not the thing to do, to much lost response, more smoke higher egts, lower average boost.

You have to ask your self a question, Where does the engine spend most of its time, Rpms and Throttle positions?

The factory turbo is sized for just that.

So Unless your going to race your truck Don't touch the turbo!!!

Interesting. According to the people who sold it to us, it WAS a 16cm2 housing. I guess they might be wrong... hmmm And it was a 2000 ISB. .

In any case, this truck will be used mostly for grunting around, loaded to about 13,000 to 17,000 pounds. It'll be used for crawling around the boonies, heavily loaded, doing service work.

I take it you're into drag racing?

I have wanted to ask you what nozzles you're using when you say "Cummins 300 hp injectors". The books we have don't list anything over 230HP. But, then, I think they have only the certified engines in them.

EDIT... UPDATE FLASH!!!

Ted, you were exactly correct. I apologize. We did use the 14 CM2 housing on that 2000. I hereby make a tardy resolution to never post before breakfast... #ad


In any case, that heavy truck and that turbo combo worked VERY well, with good low-end grunt - exactly as the owners need... It will be used off-road, in the mountains, where speeds and winding roads beg for wide powerbands. We were advised to use this, and it works - and works well.

I would agree to some extent that if this were a light truck, that ran on the highway and perhaps towed, needing max horsepower (read, rev that sucker and keep it up!) a larger housing would work better.

End mea culpa

Ted, how about an exhaust brake for stopping the new found power as well?

Don't forget an upgraded sound system. As far as I know that will not void the DC warranty... . YET. heheh

Ted is dead on with his recommedation against a larger turbo housing. A larger housing will kill your throttle response, as it is best suited for high RPM horsepower. A smaller turbo will spool up faster and is better suited to the low RPM grunt nature of our diesels.

My research has led me more toward reverse thrusters to provide adequate deceleration.

Powerwagon,
If that turbine housing came off a 2000 ISB, Dodge it's a 12cm2.

HVAC, I like that nickname BIG. It reminds me of Don Garlits.

"Big here"
Reverse thrusters are a warranty issue HVAC.
They can leak too.

The stock housing we took took off had MUCH larger openings than the one we put on. In fact, the openings are larger even than the housing on a stock 92, which we had in the shop today. I don't know how to estimate these things, but I would guess it's more like 20 or 24 than 12. To give you some idea, the stock 2000 openings were well over 1/4 inch wide, and the 14cm2 housing openings were about 60% of them.

Today, for instance, at a customer's request (a 1st gen'r and tdr member) we put on a 16cm housing on a 92. The original wasn't greatly larger, especially not the size difference of the one on the ISB we just did.

HVAC & Scott1... tisk tisk , two main hitters on the forum both making errors on the same thread... Scott1 read #9 on Teds post, HVAC read Scott1 laps and do the math again. . now guys we must provide exact info on the board or as sure as God made green apples someone will jump down and kick ya about spount'n bad info or worse yet selling somthing without declaring your a vendor... LOL... Gary

I guess my speed reading is too fast or the diesel is leaking onto my eyes. #ad

Math is theoretical big "Willy". Horsepower is emotional in theory.

"Willy", you spot "Large" cheatin', he's double postin' to gain an edge! I think Rob should flag him into the pits for a timed penalty. If he'd stay still for a couple minutes, I'd sneak up an let the air outta his tires (not easy on a dually).

 

[Ladders]

HVAC, u couldnt slo dwn long nuff to let the air out of anything, let alone duallies. Who's cheating??? not us'ns... ... . !!!!
