I am in the process of buying a 92 Dodge D250 and I have been told that there are a few things that you should do immediately such as the kdp and turning up the fuel screw. I was also told that to straght pipe a diesel is not always the best route to go since a vehicle has a optimum operating temp and also not to run dual exhaust. As well I live in northern Canada and was thinking that a high idle switch would be good as well if I could have some suggestions that would be great.

Sounds like you have been talking to one smart person and several dummies.

Take care of the KDP and the timing case bolts ASAP.

You should wait until you have a pyrometer installed to turn the fuel screw.

The only reason not to straight pipe a diesel is if you value your hearing. It will not run colder.

A 4" single system is plenty big, but if you want duals they won't hurt anything.

A hand throttle is easier than a high idle switch.

 

DJTurbo/David, welcome to the forum! Yep, the KDP needs to be killed, and tampering with the IP is always fun. But be sure to get at least a pyrometer to keep an eye of EGT's. Straight piping is fine, if you don't mind the sound. It's actually going to help with temperature a little, due to less restriction. A 4" exhaust pipe will give you optimum performance. Optimum operating temperature? Never heard of that. There are high and low limits of course, but most of our trucks run around the 900° to 1050° range, under 'normal' driving conditions.
Not run dual exhaust? Why? Just split it somewhere around the differential and it'll be fine. Or go for stacks! It's possible someone was mistaken in thinking that duals would give less backpressure, which it would if you had a split manifold and two turbos...(mmm, there's a thought! ) but otherwise it should be fine.
Hope this helps, and give us some pics when you get it!

WELCOME!!

You are partially right, There IS an "optimum temp range" that any engine is designed to operate within, but you'd just about have to encase one of these trucks in ice to get close to being too cold..

The KDP is a biggie, the pyro next, then you are free to start playing!

 

Thanks for all the answers and I am thinking of putting donkey ears on it and I will post pics pretty soon I just have to finish paper work and then next weekend shes coming home.

 

One other think with the a pillar gauges can you buy ones that hold more than two gauges for 1st gens thanks again guys.

 

No the only pillar pod available for 1st gens is a dual pod.

However there is a single gauge Steering column pod available as well, it's for 98-02 trucks but will work on 91-93 1st gen trucks.

 

I'm pretty sure you used to be able to, but probably not any more. Still, there may be someone out there who does... Autometer make a 1 and 2 gauge pods that you can stack together. That's what I'll be doing when I get some.

 

ya thats what I was hoping to do is stack them together and hopefully end up with four gauges as the automatics sadly don't come with a tach.

 

Autometer, and maybe someone else, (Isspro?) make a steering column pod, usually used for a tach. The pod slides right over the column. Check this out. https://www.dieseltruckresource.com/...d.php?t=173561
Or there's the dash mounted version. So many options!

 

okay as well I noticed in the pics the guy who did the tach installation had a few gauges in the panel next to the steering wheel that would be a good place for a big tach.

 

David check this out. https://www.dieseltruckresource.com/...ht=show+gauges
There should be a bunch of inspiration in here!

 

okay thanks KD93

 

DJ Turbo,
you're 2 hrs North of me.
If you find yourself down Stettler way p/m me, we can hook up.

 

I will have to do that some time.
