some vendors sell their injectors by added horsepower capacity, some by estimated power to the wheels.

 

Is it possible to get a 300 horse gain out of simply changing injectors?

 

You can put +300 injectors in, but you are looking at needing supporting mods to get 300 hp out of it, surely in the fueling dept.

 

I'm not looking to do anything like that. I just want a better rig for towing and some more hp. Not trying to build a monster. I'll admit when I get to looking at parts it's hard not to want to buy the bigger, badder stuff and just make it a nasty mo fo. But its my daily driver and I'm not looking to break the bank or my truck. I need to maintain fuel efficiency as well as remain reliable. For now lol

 

To be clear, are you looking to get a 300 hp gain, or get to 300 Hp?

That 180 extra Hp. gets expensive.

300 Hp is easy cheesy and cheap, 480 Hp. will cost some money ( Turbo, Injectors, etc. )

 

How much weight do you tow???

If you do buy a 12V...go slow with the mods..You could over do it also...where your stock turbo will not handle the fuel..Then you start getting into expensive stuff like twins,studs,fire-rings..etc

The mods I would recommed to you is 3k or 4K springs,fuel plate and timing set to 15 degrees.Why I mentioned 215 injectors is because these are stock injectors on the 215 powered trucks and guys sometimes upgrade to different injectors and usually you could get them for a good price..Thats if you land up with a 175 or 180 powered truck.

So maybe hold out until you decide on your purchase..and just do the basic mods for now once you get it...You may have other expenses like a new clutch if you get a 5-speed or minor frontend work...Go slow with things and if you want more power we could go from there...Don't want to break your budget until we know what type of truck you get and what other maintance needs to be done...

 

None of the above. I was just curious if that was possible. I was confused earlier when the pumps and injectors were being referenced by number designations and that sparked another question about injector sizes and gains.

 

A lot, usually 2 tons on the bed and anywhere from 2-4 on the trailer. When I haul hay, I have a big horse trailer and 4 horses, and a gigantic 5th wheel trailer that my buddies 07 6 speed has trouble pulling. I haven't even tried to hook up to that yet. Mostly because I don't have a 5th wheel hitch. Was gonna convert the trailer to goose-neck but worried the adapter wont hold up to the weight. Its rated to 30,000 but it looks flimsy. And I haven't installed a 5th wheel on my 3500 yet because I'm not sure I'm gonna keep it. When I was hauling the hay I could only do 45 mph without pushing past 2500 rpms. Put 2 tons of feed on there for a friend of mine's pigs and could only do 50 mph. Betting if I hooked up the 5th wheel I'd be doing about 35! That's why I am thinking hp upgrade and tranny swap, or a different truck all together. The 01 I was looking at already sold. I have been looking around and haven't found anything else that I really like yet. And after the massively informative replies to this post I am not so sure I want to sell my rig. I DESPERATELY want a manual transmission right now, my front end is garbage, I am leaking oil and ps fluid now, and my exhaust is rusted and breaking apart, my fuel gauge quit working, and I bought the truck in Michigan so it has some rust. All reasons I was considering a different truck. But she has grown on me and I'm already having sellers remorse every time I look at her and she's not even for sale yet.

 

LOL, It is almost 2 years since I sold Brownie, and I still miss her. Even though I can only drive one at a time, the 12Valvers seem to weld themselves to you.

Unless you find a really CLEAN 12 Valve with a stick, you can do the trans conversion yourself much cheaper than you can build an Auto to stand up to the rigors of your planned towing. I wouldn't consider a stick if you wanted a hot rod, but for towing, at least in MY opinion, they can't be beat.

I would worry less about the cost as well, if I were going to swap in a manual, I would spring for the SB DD3250 dual disc clutch right from the get go. Other clutches might hold, but why run 80 percent, especially knowing what a pain it is to change one?

In the interest of full disclosure though, I fully plan to keep Greenie until I can no longer drive, so I am clearly biased.

 

Your truck sounds a little sick. Have you been maintaining the fuel filter and cleaning the screen under the lift pump? There's a bowl and screen on the bottom of the lift pump. I could reach over the lt. fender with a 17mm wrench and take the bowl off to get to the screen. It would be cheap to play with your a little. I've seen fuel plates on ebay for $35. IIRC, your takes a #8. Or you could just DL the instruction to slide your stock plate. Forward is more fuel. There's an AFC spring kit but I've heard they aren't very effective on the 180 auto - don't know if that's true. The afc kit was $35 when I had my 215. The gov. spg. kit was higher and takes some skill (mainly dexterity) to install. It really woke up the bottom end but then the top end felt weak, in comparison. By that time, I had my 11 plate figured out and I ground the defueling hump down a little. I'd ask around to see if the afc and gsk kits are effective on your before deciding what to do. Craig

 

Sadly no, I haven't done anything other than change my oil, filter and air filter since I've owned it. I'm trying to keep my tools in my box with it. Once I start fiddling its all over. I am gonna keep digging and learning then replacing or cleaning. Prob not a bad idea but I am always having to drive somewhere and if I break something I'm gonna be ****** at myself. I wanna do the KDP soon as I get back home and exhaust as well as fix my ever worsening oil leak so I'll look at the screen then. My alt and ac pump are covered in oil, not sure what would leak oil down there but I'll know by Wed. Got a couple days I can spend wrenchin instead of drivin

 

The oil cooler is right behind the ac and alt - maybe needs a gasket or tightening. The kdp isn't hard to fix. I cut a tab from some 1/4" stock and found a longer bolt - I think it's 8mm x 1.25mm pitch. The front cover doesn't have dowel pins so I used a mirror to eyeball when the seal was centered around the crank and tightened it down. Craig

 

Sweet, I'll check that out this weekend. Thanks for the help

 

We are here to help...Thanks guys with all the replys...

You sure haul heavy loads...I could see way a standard would be better for you..

 

That's definitely where the oil is coming from! I crawled underneath there and checked the bolts. They were tight so I'm gonna get a new gasket. @ Dave, light loads are no sweat. But the heavy stuff I def need a tough manual. I'm gonna save for the 6 speed and the dual clutch. Don't think I'm gonna do any fuel upgrades just yet. Gonna replace some other worn parts first and the tranny sawp then see how much I think I need more power.
