NA 109
« on: November 11 2013, 07:13:28 PM »
Just picked up a 109 out of a 87 cutlass, stripped it down to a bare block.
Found 2 dot rods, all the pistons pushed out the top NP. bearings showed some wear as do the cylinder walls.
What else is worth saving other than the heads, rods and front cover?

See if the crank is the more desirable 'turbo' crank.

Pretty much block, rods and misc fasteners.   The rods are supposed to have lesser bolts in them, but I've never heard of one coming apart without the factor SPS units though.

Pick up is the same and you can weld a baffle in the pan.

I've heard it's pretty easy to make a baffle out of a VCR case.   You can even see the 'Y' from 'SONY' on my pan. lol

Is the balancer of any use? Could it be used on an internally balanced crank?

Does it have the fins on the back to trigger a crank sensor?

If it was a injected engine then it would have the trigger on it. If it doesn't then it would work for any NA or 83 and earlier turbo Buick. It can be made into a neutral balance but will need the trigger put on it.

Thanks gents I was talking to a buddy he just picked up a internally balanced crank he might try to use it is there any advantage to a trigger with more fins? would that not just confuse the ECU?
