Default Exhaust, Pump Tuning and Injectors

A nice DE exhaust system arrived yesterday, I was thinking of having all the hangers powder-coated. I'm not sure if this is a good or bad idea, any thoughts? The custom ASA Modifieds down-pipe is getting the Jett-Hott treatment and won't be here for another week so I have time to kill....

I'm also planning on having the IP rebuilt, from all the site searching I plan on a 3200 spring, Denny T stage 1 FP and that pump spacer I believe Cougar has written about. Is there anything else I should plan on upgrading pump wise?

Probably the toughest decision is which injectors to choose, I think the shop was recommending POD's but I may have to call them back.

What do you guys think? is next

Powder coating the exhaust hangers? Do you spend that much time under your truck?
Denny T stage one is similar to the M&H M2 that I have. It gives you a bit more control over fuel staging in my opinion. The M&H dynamic timing device (timing spacer) is worthwhile if you need/want to maintain stock or near stock timing. It increases the timing range by about 4 so you don't sacrifice your low end for more top end. I'd shy away from the PODs, there are better choices out there.
What are you doing for a turbo?

I do get under the truck quite often, but eliminating rust is an obsession with a 26 year old daily driver.
You're right I might as well get the fuel pin from M&H as well.
I've noticed the POD's weren't that popular around here. I don't have any idea what to look for, I just do a little mild towing and don't want to hurt mpg too much.
I'm gonna let wallet recover for awhile but I'm guessing on an HX35 2nd Gen if I'm reading the reviews around here correctly, unless I can get a custom turbo built by Pigiron....

POD smoke like a freight train and don't build much power.

I kinda place the HX35 in with the PODs. Good for their time but better things have come along. An HX40 or a popular one is one of the 351 variants I can't remember off hand. You already have the 4" exhaust, might as well put it to use.
Injectors are a really fickle subject. The discussions are endless. Number of holes, size of holes, spray angle, sac/sacless/minisac/microblind, edm or honed, pintal type. The main thing is don't have more fuel than the air flow can support. Otherwise you just generate smoke and high EGTs.

POD's are cheap HP but they have their drawbacks. With the range of 2nd gen tips available looking in that direction is worth your time.

A Garret Powermax Stage 2 would be a good turbo, little spendy but good. For more bang for the buck than an HX35 gor for an HE351. An HE351VE if you want to do a little mod work to get things working but it packs a lot of punch for cheap.

The HE351ve has an electronic controlled actuator, which are causing a lot of grief out there as they are expensive and are usually the main cause of failure, which most people overlook, so they send in the entire turbo for rebuilding, whereas it was only the electronic actuator. I read in a Diesel Magazine a few months ago, that some guy installed one on his first gen and controlled the variable vanes with a cable. We also drill the bearing housing and install a plug, that you are supposed to remove and squirt WD-40 in it to stop the vanes from sticking. Thats a crock. There are a lot easier turbos out there.

Those won't work being they are 24v.

However I do have several options available.
