Cheaper Fuel pump options: (From J-body.org FAQ)
Compatible fuel pumps that are direct bolt on and are better flowing:
'92-'95 S-10 Blazer with a Vortec 4.3 VIN:W
'89 Firebird 3.8
'97 C-1500 Chevy Pickup with a 4.3 Vortec VIN:W, a 5.0, or a 5.7
The specs for the pumps are as follows:
Stock pump - Free Flows 80psi@28gph (gallons per hour)
Operating Flow - 45psi@20gph
New Pump - Free Flows 100psi@47gph
Operating Flow - 51psi@41gph

Also with an Eco I would reccommend you get a custom intake manifold made to prevent fuel puddling common with this engine's stock manifold design!

Free flow = 0 psi
Dead flow (no flow)= maximum PSI
As pressure goes up, GPH goes down. All the "freeflow" #s are wrong.
A better example would be:
Freeflow - 47gph
Maximium Pressure - 100 psi
Operating flow - 51psi@41gph
Quote:
Autolite 103s cross to both Champion RS9YC (colder the Champion's stock plug) and NGK TR5 (same heat as NGK's stock plug)
NGK TR71 does not seem to exist. TR7ix does (small case so 'i' does not look like '1'). They have the same body design specs as the 2200/2.4 plugs (Not ECO) but the do not directly cross to any stock plug.
Delco FR2LS cross references to stock heat range plugs.

Don't need to change compresion ratio.
Don't need copper head gasket.
Shouldn't need rods (but they can't hurt)
Quote:
Don't need a fuel pressure regulator
Don't need a progressive controller (would be nice for off the line though)
Don't need any head work (although better exhaust valves would be nice)
Don't need Bearings
Don't need Lifters (leaves me kinda curious how to 'high rev' with the stock rev limiter in place)
Quote:
TR6s do not fit ECOs. I know several "experts" will argue this here.... mostly saying "they work in my car".
They fit in your car. They will fire in your car. But, the shorter plug leaves exposed plug threads in the head. The sharp edges of the threads increase the likelyhood of detonation as much (or more) than the colder plugs decrease it.

You need more MSD components than just a DIS-2 to make it function on an ECO
Quote:
10:1 is stock compression, forged pistons are a plus.
Don't need rods, GM has tested them to 320hp as per the 1st ECO build book)
Don't need regulator.
Probably don't need fuel pump.
Quote:
Don't need progressive controller.
Don't need ported head.
Definitely don't ever need bronze valve guides.
The ECO manifold is pretty much the same as the 2.4. Why is one worse that the other?

-Easier air flow going through the head causing less stress build up
-2.4's and 2.2's are known for throwing #3 bearing at some point in time
-The lifters just aren't good for high revving, they're great for high impact applications most commonly found in a racing application (spraying that much I'd believe it was a race application)

From what I understand you pop out the little valve that its there then connect the braided line. As for the complete instructions on every engine I'm afraid I don't understand what you mean. All nitrous systems for J's are pretty straight forward and instructions can be found at the nitrous manufacturers website. I just listed here in the sticky what was specific for that engine. 2.2-2200-2.4 guys would T off the high pressure fuel line, and Eco guys would pull straight off that aluminum line as pictured above.
If you need more help PM me and I'll get more detailed.
