i'm looking to replace my car with a junkyard motor anyone have any advice on what i should do? car got hit on the side, 50k miles they've only had it for a couple weeks. Engine needs the Oil pan R&R is that a bad sign?

 

no its not a bad sign i would have them replace and fire it up so you can listen for noises

 

Usually engines come with some type of warranty.

My buddy just replaced his engine with the Saab 9-3 motor (identical - only small modifications needed)

 

doesn't come with supercharger and its out of the car already it does however come with a 90day warranty but would suck if i put it in and it broken.

 

would the Bottom end of the saab 9-3 Motor LK9 bolt to the LSJ head?

 

We swapped oil pans and the girdle look the same. So I would think so

 

Can i drop in the whole saab motor. I've been reading that thread on super saab but how much of a pain is the wiring
saab motors are also alot easier to find as well as CHEAPER to buy from the junkyard

 

What wiring? just trade all your LSJ sensors over and plug in. Have to use LSJ coil packs (saab ones didnt provide spark)

Also drill out intake manifold holes for the larger LSJ bolts and shave down the nub that sticks out so the tensioner doesnt rub.

 

what u mean trade over? would it require me to cut and splice all the wires?

 

No. All sensors have plugs on them. Unplug them, pull motor, take sensors off old LSJ engine and install/replace on the saab engine, replug in once motor is installed.

 

thats a plug and play it's that easy huh?

 

Yea besides the stuff i listed, and swapping oil pans.

 

is the LK9 any stronger in the bottom end than the LSJ.

 

Nope.

 

its not an lk9 , its a b207 is the engine code.
one of the sce members swapped to the saab
engine and word on the street is that stg1 zzp
is the cams that is on the b207


he just have to grind a part of the engine so the
idler pulley doesnt grind on the engine.

 

which head flows better LSJ or b207r? and if i have LSJ cams/solid lifters could they fit into a b207r head? or just stay with my head

my Options have come down to.

Buy a LSJ motor for 1500-2k

Buy a B207r 600-800 .cheapest possible way

Buy B207r Plus build my LSJ head with cams,lifters,springs and swap, if possible, make decent power for price.

Get a shop to Rebuild my motor from ground up. 1800~$ thats with P&P and balancing.

I really just wanna get my cobalt up and running to enjoy it again.

trying to do this for UNDER 2k
