3.2 from SC vs. 3.2 from 3L turbo?

[}{arlequin]

some theoretical opinions please


all things being equal, what are the advantages/benefits (if any) of using an early turbo case to build a ss 3.2 vs. a ss 3.2 being built from an SC donor?

assume that P&C's/cams/intake etc are all identical.

is the difference in the crank? rods? length or weight?

thanks.

Correct me if I'm wrong, but early 3.0L turbo uses the 2.7 crank, being lighter and offering better revs... (but isn't quite as strong)

Chris is right; you could use either one, but if you are at the "parts collecting" stage you might as well sell the 3.0 turbo case to a 2.8SS racer and use an SC case for your build. the SC 9-bolt crank bolts stay tight better at very high revs, but for a street application this is unlikely to matter. If you have a case, crank, and rods you really want to use, I don't see why not.

that's the problem. i'm sitting on parts for both versions and other than uniqueness and a hidden desire for a frankenmotor, i'm not sure of any other benefits

i know there was something w/ the crank journals, but i don't remember. turbo pump would be nice to have as well. anyone know if intermediate shafts between an SC and 3L turbo are the same?

If you're building an engine 3.0 or larger the 3.0 turbo case has no advantage.
The 9 bolt crank of the SC is better in all aspects.
The advantage to the 3.0 turbo case is that you can put a 66 mm crank in it to make a high revving engine.

The intermediate shaft is the same.


Consider me a buyer for 3.0 Turbo case.
