What is the production date of your 92?
If its pre-may/92, then you had a spring type tensioner. If you installed that 95 engine without intalling the Fan support/Hydraulic tensioner from the 95, it will continue to jump time.
If it has the correct 6/92-95 hydraulic tensioner and all related pieces, you may have a failing/failed tensioner. And i know its a silly question, but (if you have a tensioner) is it screwed in all the way? It needs to be bolted down tight flush to the fan support.

I used the hydraulic on from the 95 also the 92 had the same. I did think of that and used the one from the 92 that had less then 200 miles on it. both are new... I had made sure the bolts are tight, I used the impact gun while it was out.

I am having a tough time visualizing why its jumping time then. Does it only do it when it runs? Have you tried turning it over by hand several times to see if anything is out of the ordinary?

Part of the problem is it won't run. I crank it over and it won't start. The motor is tight as all the internals are new so turning it over by hand sucks. I have only turned it about 4 revolutions. I am not sure as to way it is doing this either.

It will turn over by hand, it's just tight.....I Think I found one of the issues. the new timing belt is about 3 teeth longer then the old one........

haha uh, yea, that will do it.
I take it you didn't get your parts from Toyota eh?
If you ordered a timing belt from a 95, they may have given you a 95 Tacoma timing belt (5VZ)

I'm not sure what the belt is for but it no workie on this motor. I installed the old one and still no start. I am beating my head on the desk trying tofigure this out, I'm not a nOOb when it comes to engines. I also tried turning the crank one revolution then installing the belt, still nothing. I can't even get a back fire...it acts like there is no spark at all and I checked the whole system....nice blue spark at every plug.....

not this time. I got a kit online and it came with a timing set. should have known better....I had to throw the H/G in the trash, they were so thin and look like crap!!!! if I didn't have 1,000's into this motor I would just put in a 22RE-T.....

ok heres what my old boss told me on mine, same issue. its called washed out cylinders, its when you try to start your vehicle and flood the cylinders with gas on a new engine it takes all the oil out of the cylinders and the pistons dont have a seal, so you just hold that starter for a while and see if she'll fire up. scared me doing this cause i held the starter on for about a minute at a time, then she woke up and started.....

if all the match marks are correct with the timing belt, its in time. You can't have the crank one revolution off....since its exactly that. One full revolution, or 360 degrees. That puts it right back to where it started.
Engines have cam gears that are exactly 2x the size of the crank gear. hence the 4 stroke engine.
