I am wanting to do a V8 conversion from a 2.5L 4 cylinder. The engine from factory is very faulty and most people have blown them up and left the engine for dead from these models.
Was wondering what paperwork it takes to get the S10 legally swapped out using the ODB1 or ODB2 computer and smog equipment, under the NC Inspection laws.

92 models are not subject to OBD inspections. Must have catalytic converter though. It will have to pass the lights, tires, ball joints, glass, exhaust system (catalytic and no leaks) etc.

The engine you end up using has to be the same year of the truck or newer and has to have all applicable emission controls to that year. In other words you cannot use a 1991 or newer engine (since the truck is a 1992) and let's say for example, you find an LT1 out of a 1994 Camaro....the engine will have to have every emission control the 1994 Camaro had.

So yes that means you'll have to have the catalytic converters, EGR valve, charcoal cannister, etc.

Once the swap is complete you will have to have a referee station inspect it and verify the swap was done right using all applicable emission controls, etc. Then they'll give you a door jamb sticker that will indicate the truck is certified street legal and then you should have no problem passing NC inspection.

The following website deals with V8 S-10 conversions and has baed their info off of California smog laws. Good reading:

Best of luck. As a former V8 S-10 owner myself I can tell you these trucks can haul ass when set up right, get the same if not better fuel economy than the 4 cylinder (provided you keep your foot out of it) while having plenty of power on tap....and surprise quite a few unsuspecting folks.

I TOOK A 89 305 HO OUT OF AN OLD POLICE CAR AND PUT IT IN MY 92 S 10 WITH A 4.3 IN IT . WE TOOK THE FRONT END OFF AND MADE IT EASY TO DO .I DID KEEP THE S10 RADITOR WITH NO PROBLEM DURING THIS PAST SUMMER IT RAN ABOUT 195 TEMP EVEN WITH THE A C MY 5 SPEED MANUAL WORKS FINE.I TOOK EXHAUST MANIFOLDS FROM A 94 CAMRO 350. I HAVE AN OLD DAYNA 60 REAR END FROM AN OLD CAR WITH POSI TRACK GOING IN THIS SUMMER. I DO HAVE A LOT OF WHEEL HOP. BUT WHEN I WANT IT TO DO WHAT I WANT I WILL. I BOUGHT THE MOTOR MOUNTS FROM A PLACE IN MOLINE , IL. DON'T REMBER WHERE FOR $ 50. BUCKS. GOOD LUCKhttps://pics3.city-data.com/forum/ima...ons/icon14.gif

The best motor mounts are these: https://shell7.tdl.com/~jags/Pages/P...onvsnMnts.html

They adapt to the 2.8 liter clam shell mount (the ones that bolt to the frame) and then bolt to the side of the V8.

If your truck had the 4.3 in it, you can reuse the radiator, but it's usually best to opt for this radiator: https://shell7.tdl.com/~jags/Pages/P...-Radiator.html

Also for simplicity JTR recommends the 82-92 Camaro/Firebird low performance manifolds. Or you can use the shorty Hedman headers which only have small 1.5 inch primary tubes, so they're good for a 305 or maybe a less than 300 hp 350.

Wheel hop can be cured by getting a set of Cal Tracs, thru Jegs or Summit.
