*/C vs. N/A differences (series 1)
I know there are a few internal differences. Since I am going all out on the rebuild of the */C motor, and replacing many internal parts along the way, I am in need of this information. I can find many S1 N/A'* around here, and 1 in particular since it only has 80k on the clock. So far, I only know that the pistons and connecting rods are different. The crankshaft is the same. In particular, I want to know if the camshaft is the same, but any other parts that are different please post. Maybe once a complete list is done, maybe post it in tech info.

Here'* the list as I know it:
Pistons (pistons and rods use a sleeved/bushing wrist pin, rather than floating like the L27)
Rods
drive axles (much beefier)
harmonic balancer (don't re-use your original 93 balancer. Get a new one)
fuel pump (new also. This and the HB are long past due)
LIM (duh)
accessory brackets
wiring harness
PCM
This is off the top of my head. I've probably overlooked one or two little things.

Ooops...I guess I should have stated "long block" differences :? Basically, the rotating mass (w/exception of the crank and cam) is the only difference between the L27 and L67. Remember, only discussing internals, no accessories.
My balancer looked good from what I could tell, but will replace it when this Frankenmotor is running. Same with the fuel pump...will prob go with a Walbro unit.
Thanks for the input guys...I will have pics of the teardown up soon, already have the radiator-side head off, should have more comming off tonight or tomorrow.

I posted the other 'non rotating' stuff simply because someone else in the distant future may dig this topic up for a different purpose than you are needing it for.

The frame and subframe are identical. But the L67 powered cars USUALLY have FE2 suspension.

I may very well need that hoist when I go get that motor. A local shop is doing me a huge favor by letting me do half the work for this buildup, and the other half of the work has been done via trade on some car audio equipment I am not using, so parts is all I need to come up with.
