need help selecting injectors
Ok, I have researched for the past 3 weeks and come to the conclusion that I need advice/help selecting injectors for my specific application. My truck just hit the shop due to my leaking head gasket getting to the unmanagable point. Might have other issues as I have a abnormal sound about 1750 rpms which sounds like a piston skirting or possibly a bad wrist pin. Been holding off as long as possible so I could accumulate goodies, but I can no longer hold off the rebuild.
I have stockpiled a
* colt stage 3 "big stick" cam and retainer
* colt tappets
* new cummins macanical lift pump
* pac brake remote oil filter
* ddp afc spring
* crazy carl tunnel ram intake
* arp head studs (standard, not 625+) Will be also porting and o ringing head
* adding the 4k springs to my pacbrake gov kit
* pac brake 60lb springs
* steed speed manifold from commonrail (also will be port matched to rectangular/ 12 vcalve style
* compounds using my he351cw, bd piping and I.I. s474
* case valve breather kit
* fleece coolant bypass kit
* and though I have not purchased them yet, was also thinking of picking up ddp's performance dv's
Now, I need injectors. First question is whos injectors, second is what size. I have the 215 pump, 5 speed. Daily driver and tow rig. Never tractor pull. south bend 3250 5k kit already installed. I've been toying with ddp stage 2 or 3, but do I really need to spend $850-$950 for injectors that I will never compete with?? read good things about SDX's, but can't for the life of me find a website and I've read many posts of peeps waiting 2 to 3 months waiting for thier injectors. I cant wait that long with my truck sitting in a performance shop. I heard DAP's were good, but for half the price of ddp's, I'm skeptical. any opinions out there???

Sdx 5x.014's or 5x.016's depending on what kind HP you want. The 16's would get mo hotta while towing though.

DDPs have the wrong spray angle for your Pistons unless your getting bigger bowls. I'd go with a set from Weston (Smokem on here) first choice or SDX 5x14s second choice.

These are what I'll be going with. http://www.xtremediesel.com/MAHLEMot...cePistons.aspx
I believe that is still stock bowl size/location.

pretty sure sdx is out of business. they were building to westons specs I think.
I just put a set of westons 5x14's in a couple months ago. cannot be happier. runs good and I am getting better mileage than I ever have. the price is better than just about any others as well.

Thanks everyone for all the great advice. Going to go with westons 5x.014's. just trying to make a final decision on dv's. I dont know what westons 100cc 7mm dvs translates to. I'm still definately in my learning curve in the diesel world, so forgive me

Weston can tell you how they compare in flow rate.
024 and 7mm are not equivalent from what he sent me.

7mm outflow 024s. If I remember correctly 024s are good for 50cc's. I definitely noticed a difference going from 024's to his 7mm's. With twins I don't think there would be an issue running his DVs. Mines a little smokier with them but the single 75 is pretty unforgiving. And I haven't had a chance to tune in my AFC to it.

SDX is no more. Chris Luttrell (Member here, xaq___) is now operating as Ducky Fuel Injection. Great injectors, great prices, great guy.
