first, here's what happens:
accelerate gently through first gear, shift at 3k. accelerate gently through second, shift at 3k. accelerate gently through third - this time it takes a while, shift at 3k. crawl through fourth but can't make it to 3k even with wot. put it in fifth and it won't accelerate at all - even at wot.
so here's the story:
i got a n/t 4g63 from a fellow dsmtuner from canada. he said it had roughly 60thousand miles on it. i tore it down to the shortblock. i left the crank, rods and pistons alone. i checked them and made sure everything was ok and it seemed to be. i eliminated the rear balance shaft and left the front one in without running the b/s belt. everything was cleaned and reassembled with new gaskets. the only difference in the engine is the brand new 3g lifters in the head and a blocked off egr valve using a block off plate. a few other things that i don't think are important but could be are that i have a solid intake pipe, header, and 2.5" exhaust, iridium plugs, and 10mm wires. i also have polyurethane mounts and haven't put the axle-back part of he exhaust back on because i need to have a different muffler put on.
after i dropped the engine back into my 92 laser, i fired it up. it was the easiest initial start i've ever had after extensive work. it ran great with the exception that it kind of sounded like a diesel engine. i let it run for a while and the ticking got a little better, but it's still pretty bad. the engine ran for about 20 minutes.
well tonight, i bled the clutch and took it for a spin for the first time in almost 2 years. it's been so long because i beant the intake valves when the b/s belt broke. i removed the engine to build something crazy and never got around to it. so it sat for a while. since i've got a fresh head gasket, i was taking it easy on her - that's why i was shifting at 3k.
so what's the deal?
here's a few other things that may or may not be helpful:
i used the original wiring harnesses and sensors that are on the laser - not the ones from the engine. i don't have a vaccuum hose going to the top (round part) of the egr valve - i don't know where that line goes anyway and i have a blockoff plate. what little gas was left in the tank was mixed with some fresh gas, but i've still got less than an 8th tank. my timing is on (both mechanical and electrical). the biss was tinkered with because i wanted to replace it with a newer one that i had, but i couldn't get it out. i believe i have it reset where it should be. i have a hacked maf which worked just fine on the car before the "new" engine. lastly, i haven't performed a compression check because i don't have the tool for doing it.
you're help is greatly appreciated. if i think of anything else that i should add, i will do so. if you need more information, let me know. i will also update if i make any progress or have anything else to add. thank you.

so we adjusted the CAS... maxed it out and it was still about 20* BTDC. out of time... but not adjustable electronically = out of time mechanically

Sweet! I had no good advice for you but I've been following this thread anyways. Glad to see you got it fixed.
