Hey Guess what?

[Diesel Freak]

My BOMBED 2001 HO is up for sale, and I will be getting a 1990 1st Gen!



The truck is a 5spd with over 300K on the ticker.



What should I look out for?

Yo Freaky Diesel-type dude,



By 'getting a 1990 1sg gen', do you mean you want specifically a 1990 model year, or any 1st gen? There's actually quite a bit of small differences between the years, but they're all still on the road...



Typically (and the Brothers in the Choir will back this up) the 91's up to the 93's have the factory intercoolers, and if yer looking you might as well go for one of those, and they also have the overdrives. No factory transmission will hold up to a big-horse Cummins (verses a stock one that is... ), but a stock to mildly turned up one will hold up just fine. My trans just has a converter, and not the best one at that, but good enough to do the job (for now :-laf ). That said, if you're looking, I guess I'd look for a 92 or 93, only based on the other goodies that are stock on 'em. And they're out there, just have to keep a lookin' and one will eventually fall in your computer screen, then you just have to beat the other bidder... (ebay rocks... )



Ask any question you can think of - there'll be somebody in here that'll give you the straight scoop. Heck, I think just about everything has either been tried or is currently working. ... oh, and welcome to the jungle!

the truck I am getting to replace my 24 valve is a 1990 5spd 4x4.



hey who wants to buy my 24 valve?

 

[Bluebird]

I vote for a '92-'93 a few more user friendly items included. Search autotrader.com and you can search across the country as a comparison guide and possibly find a great truck nearby. Good luck, this is a fine generation. I'm taking my on a long run today-I'm positive all will go well.

Patrick.

Cliff,

If I'm not mistaken, and please correct me if I'm wrong, but as I understand it, you already have the truck lined up? All the recommendations for different years/options do not apply.



Sometimes ya just gotta bomb what ya got!

Welcome to the 1st Gen group. This "BOMB"ing could be a lot of fun Oo. Oo. I'm going to try to go to Newberg at the end of Oct. - I'd like to talk to about this "beast" - if you'll be there.

[Diesel Freak]

cool



Newberg it is!

Well spank me and call me Wanda... . ... Freak... buddy... . tell us what your plans are for an engine and injection pump will ya... . ... no sneaking in here with a p-pump'er you dog... .



Keep an eye on him you guys...



Things to look for... we got lots of that kind of info in here on a search but...

Watch for the leaky stub shaft on the steering box. . and the lame steering coupler (all right were the steering shaft enters the s-box. )



Look real close at the steering box mounting plate that attaches the box to the frame rail. They can develope cracks on or around the "radius" of the contours of the mounting plate, and also around the bolt holes that are used to attach it to the frame.

Some times you need to really "load" the steering to see some cracks... . lift the front off the ground and steer full stop to stop right and left. If it's pulling away you should see it.

Next, open the doors and get a mech mirror... . with the doors opened 3/4 look into the opening behind the fender, just below the lower windshield corner... there is a natural oblong shaped hole (long teardrop shape really) and look just below that lower edge of the opening... these trucks can develope cracking of the cowling down there and let water into the cab.

There is an "official" fix kit for this... again it will show up on a search for "cowl cracks".

Check your throttle travel... have someone push the peddle down to the floor while you look at the throttle "cam" rotate. . is should pull the throttle shaft fully back. . if not, the cable is stretched a bit over time. You can fix that any number of ways with the most common being physically lifting the peddle/bracket up off the floor, effectively bending the bracket a bit.

You can also pull the throttle cable thru it's little retainer socket on the peddle and put a spacer of some sort on it so the cable is held tighter in.

Next an easy one... check exhaust manifold gasket creep... they will creep out slowly over time due to heating expansion and contraction.

Check and clean all your sensor connections on the intake manifold. Check and snug up the KSB solenoid connection and the start/stop solenoid connection too. .



Ok, that's all from me for now of the guys will acuse me of hogging it all...



Welcome to the stable 'Freak... .

1. wash all the gunk off the engine

2. Put Redline MTL in the transmission

3. Replace the brake fluid with Motul RBF 600

4. 60# exhaust springs

5. 16 cm Exhaust housing

6. Straight Pipe

7. 3000 RPM Governor spring

8. Gauges

9. add some fuel



since she is non intercooled, I bet she would respond very well to some WaterMeth injection!

Sounds like you're going for pure raw RWHP

Think about a Piers HX40 and make sure the 16 outlet is 4" then go see Rip for your 4" exhaust.

Over fill the transmission by 1 qt - it will quiet the Getrag down some.

If the pump is original it's close to its life expectancy. Just back off the high speed set screw for now. Wentland Diesel in Milton Freewater can build you a very nice pump - they did mine. Bumping up your existing pump is easy. I think your head uses the same injectors as mine. The '89 injectors were larger but that led to cracked heads. Others can jump in about the heads.

Those running HX40s, how much did it raise your cruising EGT at 70 MPH?



My 2001 runs right @ 650F and 6 psi of boost. How do the 1st gen trucks compare?



Does Holset make a HX40 compressor cover to fit the non I/C'd trucks? Of will I have to cob up something to fit the 2nd gen outlet pipe?

I normally run at about 600 F and 3 to 5 psi as I am running on the expressway at 70 to 75 with an empty bed and my fiberglass cap.

Does Holset make a HX40 compressor cover to fit the non I/C'd trucks? Of will I have to cob up something to fit the 2nd gen outlet pipe?

I think you will have to fabricate something. That is what I am facing in order to do an H1C compressor wheel upgrade to mine.

I think your head uses the same injectors as mine

All the non intercooled heads take the larger bodied (9 mm) injectors. . BUT, you can use the smaller (7mm) upgrade injectors by using the copper "adapters". There are a combination of a washer and a bushing that will allow the 7mm body to fit into a 9mm hole.
