Yet another motor rebuild

Well, it has been a while since I have been around these parts since the ole' Saab broke in January of this year. Seems to be a spun bearing since I have found fine flakes of metal in the oil. I was about to sell the car at wholesale, but they offered $500 for it and I know I could have easily parted it out for more than that. Next I decided to see if I couldn't donate it for maybe a nice tax write off, but still not worth it. So, basically I was stuck with a car that I didn't know what to do with. After some thinking I finally decided to rebuild the motor and I am in the beginning process of doing so. Like most people these days I would like to build it into a B234, but I think the price outweighs the benefits so instead I am thinking of just replacing the bearings, JE pistons, worn parts in the motor, as well as a turbo (still looking at those options). At this moment I have the motor lift attached to the engine and have completed all steps, from Dip's site, to pulling the motor except I am having trouble removing the engine with the trans still in the engine bay. I don't know if it is that I don't have clearance to maneuver the motor out or what, but I would like to leave the trans in the bay if possible. If anyone could help me out I would appreciate it.

you are not going to be able to leave the transmission inside the engine bay. You'll need to remove it from the motor one way or another. Take the transmission off while you have the engine hooked up to the lift. On DIP's sight he meantions that you will need a load leveler to remove/install the motor and tranny combo at the same time

Hey Bran....Make sure all hoses, grounds, cables, connectors are detached, then then you can lower the engine and tranny onto a dolly as a complete unit. The car should be on stands high enough to enable you to slide everything out of the passenger-side wheel well, if you partially remove the well liner.

Yeah, I definatly would not try to lift the motor, they come out pretty easy from the bottom with the subframe removed.

Just removed the the engine tranny combo from underneath last month. It's easier than your think (as long as those subframe bolts are not tooo rusted )

If your going through the hassle of rebuilding the motor and putting in JE pistons - 2.3 is the only way to go. At this point all you need to do is source a 2.3 crank - as the pistons and block are identical.

I was under the impression the B234's had different rods too, but if not hell yeah I am going to have to try that route. Thanks for the advise everyone.

You do need the different 2.3 rods... Difference is crank, rods and pistons... I did this swap and the drivability of the 2.3 motor was well worth the cost in my opinion... Its just like a 9k or viggen on the spool-up of the turbo, about 500rpm earlier and another 50 ft-lbs of torque across the rpm band...

I love my 2.3 motor in my ng900... Its a great combo....

you will have an easier time dropping the engine rather than lifting it from the top. you will have to jack the front in way up there though. yanoz and drew are right.
