I used one of those kits on my truck. Good parts, great instructions. Much easier to do than you would assume. Jim the owner is also a great guy to deal with.

I went with the stage one kit. A remarkable difference in horsepower. I went with his pistons rather than try and find someone to do it locally, and do it right.

I rebuilt mine at 220,000. The directions will show you how to measure them with a feeler gauge for tolerance. Mine were all fine.

Yep I will soon be send mine in to have Jim work his majic. I was gonna do them myself but I have high mileage injectors with worn poppet valves. If you have Jim do the build he doesn't charge to correct poppet clearances so its money in my pocket to have him do the work. Also Jim is recommending new nozzles on higher mileage injectors. I will be getting new nozzles as well. I think they are just shy of $400.

I just got done building my second set of DIY injectors. Excellent product and customer service. I highly recommend them. I built one set of stage 1's and one set of stage 2's for the new truck (not in because of the darn weather.!!!!) Very easy, and lot's of hp to be had. Love the DIY.

If I rebuild my split shot injectors to stage 1's will they work or do I have to run a chip with them or have something done to my PCM?

Call Jim, I have no idea. One of my guys wants to do something similar, but he doesn't know either. But Jim can answer all your questions.

Kawa I spoke to Jim about turning my splits into single stage 1's and it can be done but requires new Plunger and barrels which adds alot of cost. I think the kit he quoted me was between $700-800 which is what it is still costing me now because I am going with new nozzles.


808trucken to go to stage 2's yes its just a nozzle upgrade but you will still need to most of the stage 2 kit. If I were going to upgrade stage 1's to 2's that had low mileage on them (less than 30K) I would probably ask Jim about a kit with nozzles, tools, internal and external o-rings, and a parts kit. You won't need the nozzle springs. But I would send Jim an email and let him know what you are thinking and he will make suggestions and probably quote you a price for a custom kit.

I just did the stage 1's 2 weeks ago. Just not that hard to do. The instructions and pics are great. I went with the new pistons. Same reason as Fordforever. Like the duck says, lots of HP to be had. Well worth it if you ask me.
808trucken, there's no special tooles needed for the tips themselves. Once the injector is dissassembled, you can just dump them out.

I would highly recommend Jim as well. When I had mine done he was extremely helpful with answering all my questions through email and phone calls. In the end I sent mine in for him to do. He swapped a few parts and corrected the armature clearance on those that needed it. He also tests them before they are returned. All said and done it was a week and less than $500 including shipping and insurance both ways for mine. Very happy customer, good customer service goes a long way with me.

Mileage can be a good indication of wear, but maintenacne is critical. 140k miles is on the low side. If the motor has been well maintained, you should not need any additional machining or replacement parts. You can spend some time to get an idea of any needed machining by following the instructions on the Tech page of the DIY website. This can even be done with the injectors in the motor, with only the valve cover removed.

Again, maintenace is critical. I've personally seen injectors with 100k miles that were totally trashed, and 300k mile injectors that needed nothing but an overhaul. I'd also point out that 150k miles seems to be the practical service point when these injectors need an overhaul. They are mechanical items and have parts that were out like everything else. Just because your truck 'Runs Good' doesn't mean it's running as good as it could be...

Good luck.
