I just want to keep it that way (ECM) because it serves as the clutch safety and everything..

Got the car driving around the other night with nothing more than a wide band o2 sensor for gauges and it is pegged at 10:1 AFR with any throttle input... I wouldn't have thought that the tune from Wait4Me would have been that far off???

ig109

Ok.. So i put a few miles on the car.. About 30.. keeping it out of boost and running it gently.. ran into town to a car show.. shut it off.. went to start it back up to show a friend that it does indeed run and it sounded like the lifters were dead.. shut it off.. refired later.. same noise.. gauge reading 0 oil pressure..

Hooked up manual gauge... 0...

WTF.. has anyone had an issue like this where the oil pump just dies..

Did you swap oil pump pickup tube o rings? There are 4 different part numbers

ig109

Oil pump pickup was not the culprit.. Pulled drain plug and the pan contained what appeared to be metalic paint....

The plug magnet was a ball of shavings..

There are pieces in the bottom of the pan that are big enough to feel..

No clue what could have happened.. Aside from new head gaskets and cleaning all the external pieces of the engine it is as it was from the salvage yard.. albeit with 218K miles..

Any guesses as to what happened?

Sorry to hear about the engine. Maybe you spun a rod bearing?

Do you have any pics of the engine bay all put together?

Man that sucks!! I feel your pain, after i rebuilt the 4.7 in my Jeep and got it running the cam sprocket bolt snapped on the passenger side head and bent valves on the rebuilt head and nicked some pistons.... with only 15 minutes of run time!! But honestly I was following your build after recently picking up a 02 6.0 for my G body and tearing it down to find a spun bearing and researching to either n/a or f/I... after stroking it to a 408. may be a blessing in disguise? I just finished doing a ls1/t56 swap on my 85 Grand prix but want more power already! good luck and continue with the project can't wait to see it done!

Here's a picture of the engine bay all done.. No AC lines yet.. but it gives you an idea of what it looks like..

ig109

I haven't had time to pull it apart yet but here is my failure analysis..

6.0 with high miles (215K miles).. came from auto truck.. thrust bearings likely a little on the loose side due to miles.. didn't force prime engine ( i know better.. was just in a hurry ).. first crank was dry crank with clutch pressed in.. full forward thrust on bearing (dry) and that likely ruined the bearing/crank surface.. once it was running every time i pushed in the clutch to shift i would say that it worsened the wear.. once it got to the point where endplay was too great.. It pushed the G rotors into the oil pump cover and trashed the stuff..

BTW.. I am thinking about getting into these swaps next fall.. Seems lots of people are doing it now and I have a recipe that seems to work well..

Also.. If anyone following this thread is interested I have an LS2/T56 combo for sale in the for sale section.. Taking Offers..

Thanks for posting that pic. The swap turned out really clean! Im going a similar route with my turbo piping and I hope it turns out as well as yours. Keep us posted on the engine findings.

ig109

I just want to say one thing... if you live anywhere East of the Rockies.. and need an engine or engine/trans combo.. call Sam's Riverside in Des Moines and ask for Chuck.. Truely takes customer service to a whole new level..

That is all..

ig109

Pulled the engine apart last night.. just as i thought.. thrust bearing was trashed.. oil pump also trashed.. just my luck..

Got another engine on the way..

ig109

Looks like I am getting an LQ9 this weekend to replace the LQ4.. Kind of worrying that it has the higher compression.. Guess my tune will just have to be that much closer to perfect..

ig109

Got my LQ9.. It has what appear to be (judging by external cleanliness) a brand new set of 317s on it.. and new gaskets.. looks like the LQ9s are only 10.0:1 compression too.. initially thought they were 10.4.. so i guess I will end up just swapping my ZR1 gaskets and ARP bolts on this engine and throw it in there.. plan to port the oil pump this time through and pre lube the bearings on the lower end as well as use the garden sprayer pre luber method to force oil everywhere..

Just waiting for clearance from the surgeon who worked on my kidney before i start pulling and tugging for engine install..

I'm glad to see you got a new engine.. Are you using the truck exhaust manifold on the drivers side?

ig109

It is the a factory truck manifold that I cut apart and added a V band to.. If I were doing it again I think I may have tried to run the Camaro L99 manifold on there.. and V banded that..

So does the truck manifold not fit very well? I'm asking a lot of questions because I'm just getting started on my turbo regal build. I built a log manifold similar to yours and I'll be starting on the drivers side soon. A build thread is in order so keep a look out.

The truck manifold leaves a bit to be desired.. If i had added a small piece of 2.5 inch pipe to it rather than directly welding the V band to it it wouldn't have been as bad.. If you look at my crossover the side that bands to the driver side madifold has a series of bends in it that snake it away from the frame and brake prop valve.. in fact.. once the pipes were coated and heat wrapped with two layers of heat wrap the wrap actually touches the floor a bit..

This is mostly due to my "forward" engine placement.. I put the engine in in a location that allows access and clearance on the stock AC box.. I don't like having to hack up a car to make something fit..

ig109

I am really thinking that once my Trans Am project is finished and sold and I am out of "projects" that I will start trying to pick up a few swaps for people...
