never seen this at junk yard

[mexlokote]

today i went to junkyard 30 mins away from my house i went to get a fender
for my truck and i came across this..

it was a 1987 c10

is it fuel injection? it said TBI

i was going to buy it but i didnt know what things to get any what not to get,
anybody have any idea what things to get?

[Telecasterjoey]

Thats the stock tbi setup, 87 was the first year for it.

What is it for

Just a glorified carb, the fuel is electronically injected instead of siphoned by air like a carb. Same purpose as a carb tho, it supplies the engine with fuel.

It keeps gas from running all over the top of the engine.

[meatwagon83]

its for removing and replacing with a carb, move along nothing to see here

[andrewmp6]

Yeah the early tbi injection is basicly a carb on crack.

Its to make your truck run great one day then barely run the next day.

Early ALDL TBI. 87-91 RV squares and 88-95 CK trucks had various mutations of that system. It's basically a computer controlled carburetor on steroids. It works quite well and provides better fuel economy than a carb as long as you maintain it.

Some of you guys are on crack.

The best thing that ever happened to GM trucks was fuel injection.

You can have your emission Quadrajets and the dozens of vacuum hoses around it. I'll take a TBI over that any day of the week.

I agree with the above statement by tx.f....wanna get in and go...no waiting for the cold blooded beast to warm up.....plus 3 or 4 miles better mpg

For the OP. TBI is a good set up for low to mid end torque, it is solid, stable, and dead reliable engines if you have the right wiring harness. The stock 350 TBI "swirlports" are excellent for torque. For instance, you could be pushing 255 ft.LBs at 2800 rpms and it slowly drop. These arent high horsepower engines though. People shun these engines because there mediocre port design and horsepower in higher rpms, they stop breathing at 5500 rpm with stock exhaust equipment, but ive had a roller H.O TBI in my 3rd gen camaro with just a Y pipe turn my car for me at about 6 grand.
Peak horse estimate 220 if you get the right swirl ports, they even make Throttle body injected intakes for vortecs and with those you could possibly push more with a reprogrammed spark advance, deleted o2 sensors, dual exhaust, mass air flow sensor swap, long tube headers, and i forgot, the updated edelbrock Throttle body unit that is a litte bit bigger also updated fuel pressure regulator.


hey guys, im not one to be rude, but if the OP wants to know of the engine, he can. Lets stop the bashing and keep her real

No emissions testing here (other than visual). All my vacuum lines except the brake booster and vacuum advance are plugged off and I can get almost 17 mpg highway

It's a flux capasitor!! Just don't go 88 MPH or you go into warp speed!!

Some folks don't like wires and scary looking parts. The ALDL TBI systems are dead simple and very tuneable in comparison to the SMPFI on the LS motors... I have no experience with the newer systems on my Impala yet but that speaks to their reliability.

Ugh!! I think you have that backwards

TBI systems aren't that desirable, very difficult to make any decent power with, and the software is extremely primitive, difficult to use and not much adjustability compared to a multiport fuel injection system, HPtuner makes it very simple.

With TBI you are stuck with tunercat or some other primitive software to do any tuning, and it's limited, simple batchfire stuff. It's not easy to negotiate around or use, especially for a first time tuner.
If you really want fuel injection you are better off spending the money on an Edelbrock injection setup that comes with the software, or a FAST EFI setup also with software or something along these lines.

I'll take my HPtuner and LS fuel injection any day of the week. Either that or run a carb long before I resort to TBI.

To the original poster, you found that setup right where it belongs, just keep walking,,,,,lol.

[jitteryguy]

dang ! this took a hard left turn.

Believe it or not, about 99 out of 100 truck owners want good fuel mileage and drivability and reliability and could care less how easy it is to hack the GM software on their EFI system for more mods.

[y5mgisi]

Some of you guys are nuts!!! A vast majority of tbi systems provide reliable, economic power for over 200k miles with only minor maintenance. Then, the day something goes wrong and its not a carb to rebuild, or you dont wnat to take the time to learn how to tune it, its all the sudden a piece of crap...

TBI is a win for folks not looking for max HP but want something cheap,easy, and reliable.

[Firebirdjones]

I figured that post would raise some hairs

You are 100% correct!

You're missing the point. Perfect cold starts, fantastic reliability, and being able to climb a steep hill in the woods without a single cough or hiccup... yes please. There's a reason GM used it on various engines for over a decade.

Can't believe all the TBI hate around here, sheesh. All you haters must not have a clue how to make a truck run, or you got your TBI info from someone else that can't make a truck run. I realize a lot of you guys (or gals) are going to take that the wrong way, but so be it.

[Firebirdjones]

Or,,,,maybe it's the TBI lovers that don't know how to make a carb work right.



It's not that I hate it, that's strong word, just that there are much better options out there now.

Common guys, you all are way to easy to get your feathers ruffled

[sethv]

Different strokes for different folks I suppose. I'm a huge fan of KISS, and a minimum amount of wiring. lol. The engine I have now is very not cold blooded and it starts almost every time without a hassle.
