Injector upgrades?

[frashdog]

Anyone running upgraded injectors? Single shots?

Any difference running vo?

I want to upgrade my injectors. (and turbo, gt38r)
Probably some capable of 450+hp range, that can be detuned now for my pmr motor, till I get a replacement forged rod motor that I can just swap over to and turn up the juice.

LOVE my Swamps singles. They are basically stock-size injectors, but no 'pause' for the split-shot thing - so they flow about 30% more fuel, but use no more HPO.

Power is amazing and smooooth and most report 2-3 mpg increase. They do make engine slightly louder at idle, but no big deal. You do need 'custom' tuning for singles, but thats just a good excuse to get DP-Tunes!!

Any bigger injectors and ya need to upgrade HPOP. I'm gonna put Bob Rileys 'Pulse' HPOP in both trucks. 'Big Oil' as they call it, will improve performance even in STOCK trucks, but is required to get full performance from big sticks. I can see where my HPOP isn't keeping up w/the SS in my F350 w/my HPO press gauge...

The guys at Swamps are awesome and will answer all of our dumb questions. They also have looked at alot of VO-use injectors and generally feel no damage is done by using VO. The exception is injectors that have seen boil-out or other caustic cleaners.

Be aware that if your engine has 'powdered metal rods' the max recommended RWHP is 400. We've seen several come apart below that number though. Go to FTE forum and look for how to tell if you have PMR's...

I'll prolly put Stage II or III injectors in the Excursion (forged rods!!:chuckles and turbo will be upgraded to a ????? Of course, not until the BTS trans goes in later this year!

For those who don't know, BTS builds nothing but PSD trannies and garuntees you won't break it - no matter what you do with it, towing 30k lbs? - ok! drag racing and doing high psi 'boosted' launces? - ok! Sled pullin'? - thats fine too!

So what shoulld I go with to upgrade my injectors? I have the 7.3 ex with a v3.

Go with Swamps 175/146 Singles. 1500$
The stock charger will clean them up good.




OR some B codes

I am new to learning about injectors. What are b codes?

[2000XLIFTED]

The 175 Swamps injectors are the same body as you would find in OBS trucks. 1998 and older 7.3 was a single shot truck stock, swamps changes nozzles and stuff to get them to flow 175cc per shot. B codes are from the 466 CI engines like school buses. These things FLOW some fuel. DP Tuner could detune these injectors to run almost like the stock ones you have but with B codes big oil is almost a must because of the much bigger intensifier piston which pressurizes the fuel. B codes are 2000+ $

There are also hybrid injectors which are A code oil side and B codr fuel side- same oil requirement but more fuel.

At least I think so....

Good explanation. Get the Adrenaline HPOP ($500) from dieselsite.com for all the oil ya need for B codes or get the Pulse HPOP or Overdrive unit for RIDICULOUS amounts of oil for really big injectors!

'Big Oil' is a must for any PSD build-up, especially oversized split-shot injectors.

Jason, in another thread I think you mentioned that an injector swap was not that difficult for a DIY job. I've got a good amount of experience working on gas engines (especially rotary engines) but very little on my truck other than the V3 install.

Is it any more difficult than an injector swap on a gas motor? I think I read that the injectors are under the valve covers on this engine - is that right? Any major obstacles like the alternator need removing? Would you guess this could be done in 8 hours by someone reasonably competent?

I'll try and check the service manual, but I'm interested in the opinions that I won't get from the manual.

I *may* be changing my injectors in the near term because of my stupid experiment explained in my "smoking" thread .

Well i am down to the final decision. Do I go with Swamps 175/146 Single Shot Injectors, Tow (Mild Street) or the stage 1 single shots from full force? Is there something even better I am missing?

I really dont want to do any mods or upgrades to the turbo now but perhaps in the future and dont want to mess with upgrading my hpop. Let me know what you guys would do?

Hey jason, I noticed that you said abive that the excursions have forged rods. is this true for all of them or just some? I am considering stage 2 injectors and dont want to put myself in a position to have a problem should I have pmr's.

[2000XLIFTED]

All Y2K trucks are forged a few 01's are. You can check by engine serial number or a service port on the block. Open it and see if the rod caps have a bolt or stud with nut. I think bolts are PMR engines= small chip only

My vote is for the 175 swamps.

[skyskijason]

My vote is for the 175 Swamps. By all means - DIY!! Its nothin' but nuts and bolts. Yes, the valve covers have to come off, which means intercooler (technically, CAC -charge air cooler) tubes and a few other things - but all in all, not a 'technical' job (no micrometer or peices that explode into 1000's of watch-size parts!) I think you could do it the first time in a long day. There are several sites (ITP diesel, Swamps, DieselSite) that have good instructions.

BTW, as 2000X mentioned - my Ex is a Y2k and pre-dates the PMR's. Even a PMR motor can be 'built', they just recommend staying under 400hp - trust me, that is PLENTY!!

thanks for the advice. I went with 175 swamps and had my mechanic install them today. Only cost me about $300 for the install and then of course about $150 for a reburn of my tunes from jody. It's all being finished up right now and as a thank you for the business my mechanic, who also installed my v3, is cleaning everything up to look like brand new. I cannot wait to get behind the wheel. Only things left after this are a new turbo and a tranny at some point.

I'm jealous.
