I recently sold my 92 4wd auto and bought a 93 4wd, 5 speed.
It has had the pump turned up slightly, the muffler taken off, and a large air filter installed.
Other than that is stock.
I have a pyrometer to install.

What would be the ideal build up for this truck?
I tow small loads (5-6k) several times a month, and several times a year I pull a 7000# trailer with a 3000# slide in camper (with water tank and gear).

I would like a logical list of things to do to this truck, with a focus on reliability and with fuel mileage being a consideration over more power. It has plenty of power as is.

I have been told to overfill the getrag transmission by 1 quart to help it lubricate.
I would like to install an exhaust brake at some point, but have read that I need to change the valve springs.
An exhaust is on the list also.

Also, if/when the getrag goes, what is the most common replacement?

 

What I am asking is what you guys would do to a truck like this?
Sell it?

The normal sequence seems to be larger exhaust, more air in, pyrometer, pump mods, etc.
Mainly, I want the standard recipe for a mild smoker and daily driver while still maintaining the 17.5/18 MPG.

At what point does the tranny become critical, and when it goes what should I be looking to replace it with?

 

To answer your question of what to do with a truck like yours (given your intended use), this would be my shopping list:

1)piston-style lift pump.---reliability/ability to support more fuel in the future
2)high flow banjos.---ability to support more fuel
3)hybrid turbo of your choice. HTT stageIII, PDR HX-35/16 etc.---ability to support and burn more fuel.
4)4'' exhaust---ability to get rid of more burnt fuel and get that big rig feeling
5)BOSCH 190 injectors---MORE FUEL! Good towing injector, from what I've read.
---trying to push a bunch a fuel through a stock '93 injector can be hard on the pump, according to the local BOSCH guy. Think of blowing through a straw that gets smaller and smaller. You're the pump and you have to work awful hard to get a good amount of air out the end of that straw. By making the straw end bigger, more air comes out for a given amount of work you put in. Said differently, the pump won't work as hard to maintain ''X'' flow with a bigger injector.

As for the Getrag, that's a tough one. There are a couple out there holding big power, but in short bursts. If you like to use all your power while towing, I would strongly recommend looking into a NV4500 or NV 5600 swap. I pull about 6k once a month with my Getrag and have had no problems. I built the tranny with cheapo bearings about 20,000 miles ago. So far, so good, but I neved load the tranny hard in first or second (weather I'm towing or not) and I don't use more than 1/3 throttle if I'm pulling over 10k. They look pretty tough (pics in gallery), but this is my only ride and I can't afford to have it down, so I drive like a wuss....

 

BTW----Welcome to DTR!!!!

 

Well said G1625S. I would add, go through all the fluids, rearend- additive if LSD and 85-140 since you plan on towing, t-case 80-90wt, getrag 5w30 synthetic 4 1/2 to 5 qts which is 1 to 1.5 qts over, engine oil, oil filter, fuel filter, check/clean air filter, flush/drain antifreeze, and grease everything. Thats all the basic stuff.

Then as G1625S said, a good hybrid turbo, I suggest a pdr hx35-16, piston lift pump- heck of a good idea, new injectors such as the 190's, outta make a hell of a good towing machine.

 

Jeez, I can't believe you guys forgot the 3200 RPM spring! Gotta put that in, especially towing with a Getrag.

 

oops, I was typing faster than I was thinking...and I type sloooooowwww

 

high flow banjos? what are those i havent heared of them before

 

The banjo bolts are what attaches the fuel lines to the filter head. High flow banjo bolts have bigger holes in them. You can get them from Geno's garage.

i would assume with a heavy fueled truck they would let the fuel flow better. so do they make a noticeble power increase or do they just make life easier on the pump?

 

Which banjo kit does a guys need for the first gen, or is it better to buy individually?

 

You only have/need two banjo bolts. Buy one tapped for 1/8" npt, and one non-tapped. They are the same banjo bolts as advertised for the 24V's.

 

thanks bill

 

As well as slightly overfilling your Getrag, service it every 15000 miles. It helps a lot.
